About This Service

Composite & Trex Deck Cleaning Done Right the First Time

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

What You Get With Capital Pro

Manufacturer-Approved Method

We follow composite manufacturer cleaning guidelines (including Trex-specific recommendations) so your warranty stays intact.

Lifts Embedded Mildew & Pollen

Composite's textured surface traps mildew spores and pollen deep in the grain — a hose alone won't pull it out.

No Fading or Etching

Correct pressure and dwell time clean the surface without scarring or dulling the composite finish.

Restores Board Color

Removes the gray, chalky film that builds up on composite boards over a season or two of sun and shade cycling.

No Staining Required

Unlike wood, composite doesn't need to be re-stained after cleaning — one visit and you're done for the season.

FAQ

Frequently Asked Questions

Can pressure washing damage composite or Trex decking?
Yes, if the pressure or chemical is wrong for the material. Too much pressure can etch or fuzz the composite cap, and some cleaning chemicals aren't approved for composite boards. We follow manufacturer-approved methods to avoid both.
Will this void my Trex or composite warranty?
Most composite manufacturers, including Trex, specify approved cleaning methods and pressure limits in their care guidelines. We follow those guidelines specifically so your warranty isn't put at risk.
Why does my composite deck look gray and chalky?
That's typically oxidation film combined with pollen and airborne dust settling into the textured cap over a season or two — it's cosmetic, not damage, and it cleans off with the right solution.
How is this different from your regular deck and patio cleaning service?
Wood decking needs a different chemical and pressure approach than composite, since wood can splinter or gray differently. Our deck-patio-cleaning service covers wood decks and general patios; this page is specifically for composite and Trex boards.
Do I need to stain or seal composite decking after cleaning?
No — composite doesn't absorb stain or sealer the way wood does. A cleaning is typically the only maintenance step needed.
How often should composite decking be cleaned?
Once a year is typical for most Capital Region decks, though heavily shaded decks under tree cover may need it more often to stay ahead of mildew.
How much does composite deck cleaning cost?
Pricing is based on deck square footage. We'll give a firm quote up front, and many homeowners bundle it with house washing or patio cleaning.
