Deck Cleaning
Wood, composite, and vinyl decks restored to original color and texture.
Material-Specific Deck Cleaning
Every deck material requires different care. Pressure-wash wood too hard and you splinter the surface and damage fibers. Composite decking can be scarred by aggressive equipment. Vinyl needs even gentler handling to avoid staining or surface damage.
We calibrate pressure, angle, brush attachment, and solution type for each material. A wood deck gets carefully applied pressure (usually 1,000–1,500 PSI max) and may benefit from gentle brushing to restore grain. Composite decks use lower pressure and biodegradable detergent. Vinyl decks get soft-wash treatment similar to house siding.
What Discolors Your Deck
Green or black algae and mold growth thrive in shaded, moist deck environments. Graying is oxidation, a natural weathering process that also leaves the surface dull and slippery. Ground-in dirt, leaf debris, and pollen accumulate in wood grain and composite texture.
Regular deck cleaning (every 1–2 years) prevents deep staining and deterioration. In Knoxville's humid climate, decks under tree cover need more frequent attention. Cleaning also reduces slip hazards and extends the life of protective coatings.
Deck Cleaning & Preparation for Staining or Sealing
If you're planning to stain or seal your deck, professional cleaning beforehand is essential. Any dirt, algae, or weathered surface layer interferes with stain adhesion and longevity. We clean thoroughly, allow proper drying time, and can discuss timing for your next sealing or staining project.
Wood decks often benefit from light sanding or brightening solutions after pressure washing to restore a fresh appearance. Ask us about pre-stain options during your estimate.
Frequently Asked Questions
Can you clean my composite deck without damage?
Yes. We use lower pressure (usually 1,200–1,500 PSI) and avoid high-pressure concentrated spray on composite. Proper technique keeps the surface safe while removing growth and staining.
Should I seal my deck after cleaning?
For wood decks, sealing within a few weeks of cleaning is ideal—the wood is clean and can properly absorb the sealer. We can recommend products and contractors, or discuss timing with your staining plans.
How long does a cleaned deck stay clean?
That depends on shade and moisture. Sunny, open decks stay clean 2–3 years. Shaded decks under trees may need cleaning every 18 months.
Is it safe to use a pressure washer on my deck?
Professional equipment and expertise, yes. Homeowner rentals are risky—they often run too high and cause damage. We have the right equipment and know how to use it safely.
Can you remove rust stains from my deck?
We can address light rust stains with appropriate solutions. Heavy rust may require specialized treatment or grinding. We'll assess during inspection and let you know what's possible.
