Every Lake of the Ozarks property with a deck knows exactly what summer looks like on that deck — sunny afternoons, evenings on the water, meals outside with family and guests. What those same property owners often know less well is what is happening to that deck surface over the course of a full season and multiple LOZ winters: the gradual darkening of the wood grain with embedded algae, the slick green film that appears first on the shaded north side, the gray weathered look that develops when a deck has not been cleaned or maintained in a season or two, and the black mold patches that establish themselves in the corners, between boards, and anywhere moisture lingers.

Deck cleaning is the maintenance service that stops that progression and reverses it — removing the biological growth, surface grime, and embedded contamination that accumulates on lake decks faster than almost any other outdoor environment. Done right, it restores the appearance of a deck dramatically, prepares the surface for the staining or sealing that protects the wood long-term, and removes the slip hazards that algae-covered deck boards create for anyone walking on them.

My Handyman LOZ has been cleaning and maintaining decks at Lake of the Ozarks since 1992. We clean wood decks, composite decks, dock decking, stairs, railings, and connected outdoor surfaces throughout the LOZ area. We know how lake conditions accelerate biological growth on deck surfaces, we know how to match the cleaning method to the deck material, and we know how to prepare a deck surface properly for the staining or sealing that follows. Whether your deck needs a quick seasonal refresh or a thorough restoration cleaning after years of accumulated wear, we bring the experience and the right approach to do it correctly.

Why Deck Cleaning Matters at Lake of the Ozarks

At Lake of the Ozarks, deck surfaces face a set of conditions that accelerates their deterioration beyond what most inland decks experience. Understanding what is actually happening on a deck surface and what regular professional cleaning prevents
helps explain why deck maintenance is one of the most important investments a lake property owner can make.

•Biological growth destroys wood from the surface in Algae, mold, and mildew are not just sitting on top of deck boards. They are actively colonizing the wood fiber, producing moisture and organic acids that break down the wood surface, accelerate graying, and create the conditions that lead to rot. Regular cleaning removes biological growth before it reaches a depth where cleaning alone can no longer fully address it.

•Moisture retention accelerates rot Biological growth on deck surfaces traps and retains moisture against the wood far beyond what natural rain and humidity alone would cause. The constant moisture retention from algae mats and mildew colonies creates ideal conditions for wood rot to establish in deck boards, joists, and structural framing often starting in places that are not visible until the damage is significant.

•UV exposure degrades wood surface Missouri summer UV breaks down the lignin in wood fibers, causing the gray, weathered appearance that develops on unprotected or poorly maintained decks. Regular cleaning removes the biological layer that amplifies UV damage and, when followed by staining, provides the UV-blocking protection that significantly slows this process.

•Algae creates serious slip hazards A deck board covered in algae is one of the most slippery walking surfaces at any lake property. Wet algae on wood has almost no traction, and falls on deck surfaces are a genuine injury risk particularly for vacation rental guests who do not know the property well and may be wearing inappropriate footwear near the water.

•Appearance affects rental performance and property value A gray, stained, algae-covered deck is one of the first things arriving guests notice at a vacation rental, and it is one of the most visually prominent features a buyer sees when evaluating a lake property. A clean deck signals a well-maintained property. A dirty one signals the opposite regardless of how the rest of the property is maintained.

• Stain and sealer cannot compensate for lack of cleaning This is the maintenance reality most often misunderstood. Applying deck stain over dirty, contaminated wood produces a finish that looks bad immediately and fails within one season. There is no shortcut that replaces proper cleaning as the foundation of every deck finish project.

Deck Cleaning for Homeowners, Vacation Rentals, and Commercial Properties

The reasons for keeping a deck clean vary by how a property is used, and My Handyman LOZ serves the full range of Lake of the Ozarks property owners with experience matched to each situation.

Full-time lake residents and seasonal homeowners invest in deck cleaning as part of a regular maintenance program that protects the deck structure and keeps the outdoor living space looking its best. For most lake homes, a spring cleaning before the season removing the mold, mildew, and biological growth that accumulated over the winter is the baseline. A fall cleaning after the heavy summer growth season is a valuable addition for decks with significant sun exposure, heavy shade, or proximity to moisture sources. Annual cleaning followed by periodic restaining every two to four years is the maintenance program that keeps a wood deck performing and looking well for decades.

Vacation rental owners operate in a different reality. The deck is one of the most-used and most-photographed outdoor spaces at any lake vacation rental. Guests spend time on the deck every day of their stay, and arriving guests notice its condition immediately. A clean, well-maintained deck reads as a high-quality rental property; a stained, algae-covered one reads as a poorly managed one and that perception flows directly into reviews, ratings, and booking rates. My Handyman LOZ works with vacation rental property owners and managers throughout the LOZ area to keep decks cleaned and maintained on schedules that match peak rental seasons and guest arrival expectations.

Commercial properties at Lake of the Ozarks resorts, restaurants with outdoor seating, marinas, and other facilities with wood or composite deck surfaces have guest-facing deck areas that reflect directly on the business. Algae-covered or visibly deteriorating deck surfaces at a commercial property communicate poor maintenance standards to customers who have choices about where they spend their money. Professional deck cleaning as part of a commercial exterior maintenance program protects the facility’s appearance, keeps surfaces safe for customers, and avoids the accelerated structural deterioration that comes from deferred maintenance.

Common Deck Problems We Solve With Professional Cleaning

Lake of the Ozarks deck owners recognize these conditions immediately. If any of them match what you are seeing on your deck, it is time to schedule a cleaning:

Green algae coating on deck boards

The most common deck condition at lake properties. A green, slick coating of algae that develops across the deck surface — particularly in shaded areas, the spaces between boards, and on north-facing deck sections. Algae on wet deck boards is a slip hazard and a wood surface accelerator.

Black mold streaks and patches

Black mold is common on deck surfaces that retain moisture — shaded areas, areas near the home’s exterior wall, between deck boards, and on the underside of horizontal rails. Once established, black mold spreads steadily if not removed and treated.

Gray, weathered, dull deck boards

Wood that has lost its color and turned gray from UV exposure, biological activity, and oxidation. Weathered gray decks often respond well to professional cleaning with brightening chemistry — bringing back a noticeably warmer, cleaner appearance.

Brown tannin staining

Natural tannins leach from certain wood species — particularly cedar and redwood — when exposed to moisture, leaving brown staining on deck surfaces and surrounding concrete or hardscape. Deck cleaning chemistry addresses tannin staining effectively.

Mildew and surface discoloration

Dark, patchy discoloration from mildew colonies that establish on surfaces where moisture is retained. Mildew is pervasive in the warm, humid LOZ lake environment and develops on decks faster than most other outdoor settings.

Embedded dirt and debris

General surface accumulation of dirt, leaf debris, pollen, and organic material that packs into the deck surface and between boards over time. Heavy surface contamination traps moisture and provides the organic substrate that algae and mold colonize.

Old, failed stain or sealer residue

Decks with previous stain applications that have peeled, grayed, or otherwise failed have contaminated, contamination-bonded surfaces that must be cleaned thoroughly before new stain will adhere. Professional cleaning with appropriate stripping chemistry addresses failed stain residue as part of stain preparation.

Deck cleaning as pre-stain preparation

A deck heading toward staining or sealing needs professional cleaning first, without exception. Stain applied over a contaminated surface fails within one season. Our deck cleaning sets up the surface for a stain application that lasts.

Wood Deck Cleaning vs. Composite Deck Cleaning What’s Different

Not all deck cleaning is the same. The right method, the right chemistry, and the right pressure settings depend on what the deck is made of and what condition the surface is in. My Handyman LOZ adjusts our approach to each surface type rather than applying a single method to every deck regardless of material.
Z

Wood Deck Cleaning

Wood decks — whether cedar, pressure-treated pine, redwood, or other species — are porous and vulnerable to surface damage from excessive pressure. The right approach for most wood decks at Lake of the Ozarks combines a cleaning solution application to dwell on the surface and break down biological growth chemically, followed by controlled low-pressure rinsing that removes contamination without raising wood grain, eroding the surface, or forcing water into the wood structure. For wood heading toward staining, a deck brightener step after cleaning restores wood tone and pH balance, opening the grain for optimal stain penetration.
Z

Composite Deck Cleaning

Composite decking is not immune to biological growth — in fact, the textured surface of many composite products traps organic material and supports mildew and algae growth readily, particularly in the LOZ climate. Composite decking requires a gentler approach than most wood decks — lower pressure to avoid surface scuffing or heat damage, and cleaning chemistry matched to the composite manufacturer’s recommendations for the product. Many composite deck products have specific care guidelines from the manufacturer, and we are familiar with the major brands found throughout the Lake of the Ozarks area.
Z

Dock Decking Cleaning

Dock decking faces the most demanding cleaning conditions of any deck surface at a lake property. It is closer to the water, exposed to wave spray and wake splash, subject to fish cleaning residue, oil drips from boats and engines, and the most intense biological growth pressure of any surface at the property. Dock decking cleaning is a specialized subset of deck cleaning that we handle regularly throughout the LOZ area. The approach combines deck cleaning technique with attention to the specific contamination types — oil, fish residue, bilge splash — that dock boards accumulate in ways that standard decks do not.

Our Deck Cleaning Process — The Right Method for Every Surface

Deck cleaning done correctly is not a matter of pointing a pressure washer at the boards and moving it across the surface. The method, the chemistry, the pressure settings, and the sequence of steps all matter — and getting them wrong produces a result that either fails to fully clean the surface or damages the wood in ways that affect every subsequent maintenance step.

Step 1 — Deck Assessment and Preparation

Before any cleaning begins, we walk the deck and assess its condition. We identify the deck material, note the type and severity of contamination present, evaluate whether any boards show rot, structural damage, or fastener failure that should be addressed before or alongside cleaning, and determine whether the deck is heading toward staining after cleaning. This assessment shapes the product selection, the method, and the pressure settings for the job. We protect adjacent siding, landscaping, and any furniture or features that should not receive direct water or cleaning solution contact.

Step 2 — Pre-Treatment of Biological Growth

For decks with significant algae, mold, or mildew growth — which describes most Lake of the Ozarks decks by mid-season — we apply a professional cleaning solution as a pre-treatment and allow it to dwell before washing. This step is where the chemistry does its work: the cleaning agent penetrates and breaks down the biological growth at the cellular level, making it significantly easier to remove completely without relying on high-pressure mechanical force alone. Pre-treatment followed by low-pressure rinsing produces a deeper, more complete clean than pressure washing without pre-treatment — and does so without the surface damage that excessive pressure causes.

Step 3 — Soft Wash or Controlled Pressure Cleaning

We apply the cleaning method matched to the deck material and its condition. For most wood decks at Lake of the Ozarks, this means a soft wash approach — low pressure, thorough coverage, and cleaning solution doing the primary work of removing contamination. For composite decks, we use appropriately gentle settings matched to the manufacturer’s guidelines for the specific product. For dock decking with heavier contamination — oil, fish residue, embedded grime — we may use controlled pressure in the appropriate range for the board material after pre-treatment has done its preparation work. The approach is always matched to the surface, not defaulted to whatever the machine is already set to.

Step 4 — Deck Brightening (Where Applicable)

For wood decks heading toward staining or for heavily weathered wood that needs tone restoration, we apply a deck brightener after the main cleaning step. Deck brightener is an oxalic acid-based solution that neutralizes the alkaline residue from cleaning chemistry, restores the wood’s natural pH balance, opens the grain for optimal stain penetration, and brings back the warm natural tone of the wood that graying and biological activity obscures. Brightening makes a visible difference to the appearance of weathered wood and a meaningful difference to how well stain penetrates and bonds to the cleaned surface. We advise on whether brightening is appropriate for each specific deck.

Step 5 — Rinse, Inspect, and Touch-Up

After cleaning and brightening, we rinse the deck thoroughly to remove all cleaning solution and brightener residue. We then walk the full deck surface — boards, between boards, stairs, rails, and any connected surfaces — inspecting for areas that need a second pass, contamination that persists in high-growth areas, or spots that were missed in the initial application. Only when the full deck meets our standard do we call the job complete. We document the finished work with photos for out-of-town property owners and vacation rental managers.

Deck Cleaning as Preparation for Staining Why It Cannot Be Skipped

If your Lake of the Ozarks deck is scheduled for staining, deck cleaning is not an optional preliminary step — it is the most important part of the entire staining project. A stain application is only as good as the surface it goes onto, and the condition of that surface is entirely determined by how well it was cleaned.

Here is what happens when stain is applied to a dirty deck: the stain bonds to the biological growth, embedded dirt, and surface contamination rather than to the wood fiber itself. The bond to that contamination is weak and unstable, and the stain fails at the rate the contamination fails — which happens quickly. Stain applied over mold or algae develops a streaked, blotchy appearance as the biological material under the finish continues to interact with the wood surface. Stain applied over old, failed stain residue that was not stripped peels within a single season.

Beyond adhesion, dirty wood does not absorb stain evenly. Contaminated areas absorb differently than clean areas, producing a blotchy, inconsistent finish even with a quality stain product applied correctly. Wood that has been properly cleaned and brightened absorbs stain uniformly, producing the consistent, rich finish the stain product is designed to achieve.
My Handyman LOZ handles both deck cleaning and deck staining, which means the prep and the finish are done by the same crew under the same quality standard. There is no gap between two separate contractors no assumption that the previous contractor cleaned adequately and no cleaning crew that skips the brightener step because it is inconvenient. We own the full sequence from bare wood to finished stain and we hold ourselves accountable to the result.

If your deck needs cleaning as a standalone service this season and staining is planned for later, we advise on the best timing to ensure the clean surface is ready for stain when you schedule it. If you want to do both in the same project cycle, we coordinate the full sequence properly.

Where We Clean Every Deck and Outdoor Wood Surface at Your Lake Property

My Handyman LOZ provides professional deck cleaning for all outdoor wood and composite surfaces at Lake of the Ozarks properties:

Main house decks

Single and multi-level wood and composite decks attached to the home. The primary outdoor living surface at most lake properties and the highest-priority deck cleaning location for both appearance and structural protection.

Dock decking

Wood dock boards and composite dock decking at boat docks and covered slips. Dock decking faces the most intense biological growth and contamination pressure of any deck surface at the property and typically needs the most thorough cleaning.

Dock stairs and gangways

Stair systems connecting the home or yard to the dock level. Stair surfaces are a fall hazard when contaminated and are often overlooked in cleaning projects that address only the main deck surface.

Detached decks and pool decks

Freestanding deck structures, pool deck areas, and outdoor entertaining platforms separate from the main house deck.

Pergola and covered structure decking

Deck surfaces under pergolas and covered outdoor structures that retain moisture and biological growth from overhead leaf and debris accumulation.

Screen porch and sunroom decking

Wood floor surfaces inside screened porches and enclosed outdoor rooms that accumulate grime, pollen, and biological growth despite partial protection from the elements.

Deck rails, balusters, and fascia boards

Vertical and horizontal rail components, baluster assemblies, and fascia boards that accumulate biological growth and require cleaning as part of a complete deck surface restoration.

Wooden retaining walls and fencing

Adjacent wood structures connected to or near deck areas that benefit from professional cleaning as part of a comprehensive exterior wood maintenance project.
When appropriate, deck cleaning can be combined with dock cleaning, house washing, and concrete cleaning in a single visit bringing all connected outdoor surfaces to a consistent clean standard at once.

Complete Deck and Exterior Services Available With Your Deck Cleaning Project

Deck cleaning is the foundation of deck maintenance, but it is rarely the only thing a lake deck needs at the same time. My Handyman LOZ is a full-service exterior contractor, which means we can address the complete scope of deck and property maintenance work in a coordinated project rather than multiple separate visits.

  • Deck Staining — The natural follow-on to deck cleaning. After a thorough clean and brighten, the deck surface is properly prepared for stain application. My Handyman LOZ handles the full cleaning-to-staining sequence so prep and finish are coordinated under the same quality standard.
  • Dock Cleaning — Dock decking and full dock structure cleaning is frequently combined with house deck cleaning in a single project visit — bringing all wood surfaces at the property to the same clean standard at once.
  • Deck Repair — Cleaning often reveals deck boards with rot, structural damage, loose fasteners, or failing connections that should be addressed before staining. My Handyman LOZ handles deck repair so nothing gets covered over or left to worsen.
  • Wood Replacement — Rotted or severely damaged deck boards and structural wood components are replaced as part of a comprehensive deck restoration project before cleaning and staining proceed.
  • Dock Repair — Dock structural repairs — damaged framing, failing hardware, compromised dock boards — are identified and addressed when we clean dock decking, so the full dock structure is sound before any finish work proceeds.
  • House Washing — Many of our deck cleaning customers schedule house washing in the same visit to bring the entire exterior of the property to a consistent clean and maintained appearance.
  • Power Washing — Concrete driveways, walkways, and hardscape surfaces are power washed in the same project visit — a comprehensive exterior cleaning that covers every surface.
  • Dock Roof Cleaning — Dock roof cleaning paired with dock decking cleaning addresses the full dock structure in a single coordinated visit.
  • Vacation Rental Maintenance — Property managers and vacation rental owners can schedule comprehensive seasonal maintenance visits that combine deck cleaning with staining, dock services, house washing, and all related exterior work in a single project.

Ask about bundling services when you call for your estimate. Coordinating deck cleaning with staining, dock work, and house washing in a single project visit is more efficient, more economical, and produces a result that looks consistently maintained from every angle of the property.

Safety, Protection, and Property Value Benefits of Deck Cleaning

The value of professional deck cleaning at Lake of the Ozarks extends well beyond a better-looking surface. Here is what regular professional deck cleaning delivers for a lake property:

  • Slip and fall hazard elimination — Algae on wet deck boards is one of the most dangerous walking surfaces at any lake property. Professional cleaning removes that hazard completely, restoring safe traction to deck and dock surfaces that get wet regularly. For vacation rental owners, this safety improvement is directly connected to guest wellbeing and liability management.
  • Prevention of structural wood rot — Biological growth on deck surfaces traps moisture against the wood and accelerates the rot that undermines structural integrity over time. Cleaning removes the growth that drives that moisture retention, allowing the wood to dry properly and significantly reducing the conditions that support rot development.
  • Extended deck service life — Decks that are regularly cleaned and maintained last substantially longer than decks that are neglected. The cost of staying current on deck cleaning and staining is a fraction of the cost of deck board replacement or full deck reconstruction that deferred maintenance eventually requires.
  • Optimal surface preparation for staining — A properly cleaned and brightened deck accepts stain evenly, bonds it securely, and produces a finish that lasts multiple seasons rather than failing within one. The investment in deck cleaning is also an investment in the longevity of every stain application that follows.
  • Improved property presentation for rentals and sales — A clean deck is one of the most powerful before-and-after improvements visible at any lake property. In listing photos for rentals or sales, a freshly cleaned deck significantly enhances the property’s appearance. In person, it creates a strong first impression that carries through the guest or buyer’s entire experience.
  • Maintenance issue identification — Professional deck cleaning involves a close inspection of the full deck surface that reveals loose fasteners, damaged boards, failing rails, and early rot that might go unnoticed until the damage is extensive. Catching these issues during a cleaning visit, when they are still manageable repairs, saves significant money compared to discovering them when they require structural intervention.

Why Decks at Lake of the Ozarks Need More Maintenance Than Inland Decks

Property owners who move to Lake of the Ozarks from inland locations are consistently surprised at how quickly decks deteriorate here compared to what they experienced elsewhere. The difference is real, significant, and driven by specific conditions that characterize the LOZ lake environment.

The moisture environment at Lake of the Ozarks is unlike most inland residential settings. Lake humidity keeps deck surfaces damp longer between rain events. Morning dew is heavier and lingers longer. Wave action and boat wake splash reach dock decking and lakeside decks regularly. The water table near shoreline properties is high. These conditions create a persistently moist surface environment that is ideal for algae and mildew growth — far more so than the same deck would experience fifty miles inland.

The biological load in the LOZ air environment is elevated compared to inland settings. Algae spores are abundant near the lake surface, windborne from the water and deposited on every exposed surface. Mold spore counts in the humid, wooded LOZ environment are high through the warm months. Once those spores land on a damp deck surface, they establish quickly — and the deck’s proximity to the water ensures it stays damp enough for them to thrive. An inland deck might develop visible algae growth in its second or third summer without maintenance; a lake deck can show it within a single season.

Tree canopy is a factor at many Lake of the Ozarks properties. Decks shaded by trees accumulate leaf debris, stay damp longer, and are in perpetual biological growth conditions that accelerate wood degradation. The combination of shade, debris, moisture, and biological pressure on a shaded lake deck can reduce the useful life of an unprotected wood deck significantly compared to what the same deck would experience in a sunny, drier location.

The practical implication of all of this is straightforward: the deck maintenance schedule that keeps an inland deck looking good is not adequate for a Lake of the Ozarks deck. What works as a once-every-few-years cleaning cycle at an inland property needs to be at least annual at the lake — and for heavily shaded or moisture-exposed decks, more frequent. My Handyman LOZ advises every customer on a realistic maintenance schedule based on their specific deck’s conditions, not a generic recommendation.

Why Choose My Handyman LOZ Since 1992

There are plenty of power washing services that will clean a deck. What sets My Handyman LOZ apart is the approach — the right method for the right surface, the preparation that makes the cleaning result last, and the full-service capability to address everything a lake deck needs in a single coordinated project.

  • Over 30 years at Lake of the Ozarks — Since 1992, we have cleaned, stained, repaired, and maintained decks throughout the LOZ area. We know what biological growth looks like at every stage, which cleaning approaches produce the best results on the surfaces common to lake properties, and how to identify structural issues during cleaning that need to be addressed before they compound.
  • Honest assessments, not upsells — When we look at your deck, we tell you what it actually needs. If a cleaning and brightening is the right answer this season, that is what we recommend. If damaged boards or structural issues need attention before cleaning and staining proceed, we tell you clearly and honestly so you can make an informed decision.
  • Full deck and exterior contractor capability — Cleaning, staining, repair, wood replacement, dock work, house washing — My Handyman LOZ handles the complete scope of lake property exterior maintenance from one contractor. One call, one relationship, consistent quality across everything that needs doing.
  • Surface-matched methods and chemistry — We do not apply one pressure setting and one cleaning product to every deck regardless of what it is made of and what condition it is in. Wood gets treated differently from composite. Dock boards with oil and fish residue get treated differently from a patio deck with algae. The right match of method and chemistry produces better results and protects surfaces from damage.
  • Residential, commercial, and vacation rental experience — Whether you are a full-time resident, a seasonal homeowner, an out-of-town vacation rental owner, or a commercial property manager, we have the experience and the communication practices to serve you well — including the ability to work independently for owners who are not on-site.
  • Local Lake of the Ozarks knowledge — We are not a national franchise or an outside crew. We live and work here. We know the lake communities, the properties, and the specific conditions that lake decks face through every season — and we build our business on the quality of the work we do for the neighbors and property owners we serve.

Frequently Asked Questions About Deck Cleaning at Lake of the Ozarks

How often should a deck be professionally cleaned at Lake of the Ozarks?
Most wood and composite decks at Lake of the Ozarks benefit from professional cleaning once a year — typically in spring before the season or in fall after the heavy growth period ends. Decks with significant tree canopy overhead, north-facing exposure, or heavy shade accumulate biological growth faster and may benefit from cleaning twice a year. Vacation rental decks with high guest traffic and constant exposure often warrant more frequent attention. We assess the surface condition and advise on the right cleaning schedule for your specific deck.
What is the difference between pressure washing and soft washing a deck?
Pressure washing uses high-force water to blast surface contamination off a deck. At the wrong pressure or with the wrong nozzle, it damages wood grain, raises fibers, erodes the wood surface, and can drive water into joints. Soft washing uses lower water pressure combined with cleaning solutions to break down biological growth chemically before rinsing. For wood decks especially, soft washing produces a thorough clean without the surface damage that aggressive pressure washing causes. We match the method to the deck material and condition.
Does my deck need to be cleaned before staining or sealing?
Yes — always, and without exception. Stain or sealer applied over a dirty, moldy, or algae-contaminated deck surface bonds to the contamination rather than to the wood. The finish fails prematurely, often within a single season. Professional deck cleaning removes all surface contamination and opens the wood grain to properly accept the stain or sealer product. My Handyman LOZ handles both deck cleaning and deck staining, so the prep and the finish are coordinated and done correctly.
Can you clean composite decking as well as wood?
Yes. Composite decking at Lake of the Ozarks accumulates biological growth, mildew staining, and general surface grime just like wood decking — sometimes faster in shaded or moisture-exposed conditions. Composite decking requires a gentler approach than many wood decks — lower pressure and appropriate cleaning chemistry matched to the manufacturer’s recommendations. We adjust our process to the specific composite product and its condition.
How long does deck cleaning take?
A standard residential deck cleaning at Lake of the Ozarks typically takes between two and four hours depending on deck size, the amount of biological growth present, the number of levels, and whether connected dock decking or stair systems are included. We give you a realistic time estimate when we assess the job. If deck staining is planned as the follow-up step, we advise on the required dry time before stain can be applied — typically 24 to 72 hours depending on weather conditions.
