Composite decking doesn't rot like wood, but it still traps pollen, mildew, and oxidized film in its texture — we clean it the way manufacturers recommend, without voiding your warranty.

About This Service
Composite and Trex decking is built to resist rot, but its textured surface still holds onto pollen, mildew spores, and a chalky oxidation film, especially on Capital Region decks shaded by trees for part of the day. Using the wrong pressure or the wrong chemical can void a composite deck's manufacturer warranty, so we follow manufacturer-approved cleaning guidelines built specifically for composite boards — a different approach than the wood-focused method used on our broader deck-patio-cleaning service.
Why It Matters
We follow composite manufacturer cleaning guidelines (including Trex-specific recommendations) so your warranty stays intact.
Composite's textured surface traps mildew spores and pollen deep in the grain — a hose alone won't pull it out.
Correct pressure and dwell time clean the surface without scarring or dulling the composite finish.
Removes the gray, chalky film that builds up on composite boards over a season or two of sun and shade cycling.
Unlike wood, composite doesn't need to be re-stained after cleaning — one visit and you're done for the season.
Our Process
We measure the deck square footage and give a firm flat price before scheduling.
Furniture, planters, and grills are moved or protected before cleaning begins.
A composite-safe cleaning solution and controlled pressure lift mildew, pollen, and oxidation film from the board texture.
Final rinse, furniture reset, and a walkthrough of the finished deck with you.

“In a state of bereavement we reached out and got an earlier date. When we returned from funeral proceedings the house was impeccable. Even areas we had no time to prep for were done. Nice work for sure. Call them — you won't be disappointed!”
