Professional Deck Cleaning in Lexington, KY
Professional deck cleaning in Lexington, KY clears the dirt, algae, mold, and mildew that make a deck look worn and slippery when wet. We pick the method from your deck’s material and condition, and we use soft washing where it fits. Getting ready for a cookout, planning to stain or seal, or just keeping the deck in shape? A regular cleaning protects the boards and your footing through Lexington’s changing seasons.
- Typical cost: starts between $200 and $450 for a typical residential deck
- Method: soft washing for wood, a gentle solution and controlled rinse for composite and PVC
- Composite or PVC? We check the brand first, since each sets its own pressure limit
- Staining or sealing next? Clean first, then let the deck dry before the finish goes on
- Guarantee: 30 days, and we re-clean the area free if the same algae or discoloration returns
Why Deck Cleaning Matters
Decks lie flat, so leaves, pollen, dirt, and standing water sit right on the boards while people walk over them. Tree pollen peaks here in March and April, and Lexington gets roughly 45 to 50 inches of precipitation a year, so a shaded deck often stays damp. That damp is what algae, mold, and mildew need.
Algae, Mold & Mildew Growth
Warm, humid Lexington summers create ideal conditions for algae, mold, mildew, and moss, especially on shaded decks that stay damp after rain. As this organic buildup spreads, it traps moisture against the surface.
Slip & Fall Safety Risk
Algae and mildew become especially slippery when wet, increasing the risk of slips and falls on walking surfaces, stairs, and entry areas of your deck.
Freeze-Thaw Stress
During winter, moisture in small cracks freezes and expands, placing extra stress on the deck through repeated freeze-thaw cycles common to Central Kentucky.
Staining & Wood Rot
Left untreated, trapped moisture leads to staining, discoloration, and wood rot over time, shortening the life of your deck boards.
We’ve seen these conditions on backyard decks throughout neighborhoods like Tates Creek and the Hamburg area, where mature trees give welcome shade and also keep the deck damp enough for growth to take hold.
Cleaning Wood and Composite Decks
Every deck is built differently, and each material responds best to its own method. Material, age, finish, and condition all change how we clean it. That’s why we inspect every deck before choosing the most appropriate approach.
Deck type | What builds up | How we clean it |
Wood (cedar, pressure-treated, redwood) | Algae, mold, mildew, and gray weathering | Soft wash and a low-pressure rinse, so the grain stays smooth |
Composite and PVC (Trex, TimberTech, and others) | Pollen, dirt, algae, and dark stains | We check the brand first, then use a gentle solution and a controlled rinse within its pressure limit |
Railings, stairs, and multi-level sections | Dirt and growth in corners, joints, and shade | Cleaned section by section, so every area gets its own level of care |
Wood Decks (Cedar, Pressure-Treated & Redwood)
Wood soaks up moisture, so it grows algae, mold, mildew, and weather stains more easily. Wood fibers are soft, and too much pressure can raise the grain, leave splinters, or damage the surface. That’s why we often soft wash wood decks. It removes the growth and helps protect the wood.
Composite & PVC Decking
Composite and PVC decking resist moisture better than wood, but they still pick up algae, dirt, pollen, and dark stains. Pollen and dirt that sit can feed mold, which is why Trex suggests cleaning in spring and fall.
Brands also set their own limits. Trex allows up to 3,100 PSI on its newer lines, TimberTech asks for 1,500 PSI at most and only for rinsing, and early-generation Trex shouldn’t be pressure washed at all. Bleach can lighten composite, and some brands don’t allow it. So we ask which brand you have first, then use the right solution and a controlled rinse that won’t scratch the finish or leave streaks.
Railings, Stairs & Multi-Level Decks
Railings, stairs, and elevated sections collect dirt and growth in corners, joints, and shaded spots where moisture lingers longer. We clean each section on its own, so every area gets its own level of care.
Our Deck Cleaning Process
Every deck is inspected before cleaning, so we can pick the safest method for its material, condition, and level of buildup.
Inspection
We begin by inspecting the deck boards, railings, stairs, and other accessible areas for algae, mold, mildew, staining, and signs of weathering. This allows us to determine the most appropriate cleaning approach before work begins.
Pre-Treatment
We apply a biodegradable cleaning solution designed to loosen dirt and organic growth. The solution is typically allowed to dwell for 10-15 minutes, giving it time to break down buildup before the cleaning process begins.
Soft Wash Cleaning
After the pre-treatment has done its job, we clean the deck using the method best suited to its surface, including soft washing where appropriate, to remove contaminants without using unnecessary pressure.
Final Walkthrough
Once the cleaning is done, we walk the deck and check for any spots that need another pass before we call the job finished.
Can an Old, Faded Deck Be Restored, or Does It Need Replacing?
Most old, faded decks can be restored. The boards underneath are usually still sound, and on a Nicholasville deck, years of green algae lifted off and the wood’s natural color showed through again. Cleaning also shows you the real condition of the wood, so you can decide about replacement with the facts in front of you.
Heavily weathered or gray wood may still need sanding, staining, or sealing to bring back its original color, but for most decks, cleaning does the heavy lifting at a fraction of the cost of a full rebuild.
Why Choose Our Deck Cleaning Service
Local Experience
Every job starts with an on-site inspection, so a wood deck gets the soft wash it needs while a composite deck gets a different approach entirely. On a Nicholasville deck, we walked the homeowner through what we were cleaning and why, since a deck that size takes time to do right.

Prepare Your Deck for Staining or Sealing
If you’re planning to stain or seal your deck, cleaning it first is an essential part of the process. Dirt, algae, mold, mildew, and weathered wood fibers can keep stain and sealant from bonding evenly. A coating over a dirty surface can soak in unevenly, stick poorly, or wear out sooner than it should.
Professional cleaning removes this buildup and gives you a clean surface to build on. It also makes loose boards and exposed fasteners easier to spot before a stain or sealant goes on. Cleaning can show problems the buildup was hiding, but it doesn’t repair them, so have a qualified deck professional look at any structural concerns first.
After cleaning, the wood needs time to dry. Most coatings want a couple of dry days, and the exact time depends on the weather, the wood, and the product, so follow the label. Even if another contractor handles the finishing, a properly cleaned deck gives their work the best chance of lasting.
