Deck Cleaning & Sealing in Sarasota & Manatee County
Florida decks grow a black-green film in the grain that gets slick when wet and dull when dry. Composite and Trex boards hold it in their texture; wood decks add gray oxidation and tannin on top. Cleaned at driveway pressure, composite gets furred and wood gets shredded. Kelly K's cleans decks at deck-safe pressure with a mildew-killing treatment, and seals wood decks so Florida sun and rain don't take them back in a season.
What we clean & seal
- Composite & Trex decks — mildew lifted out of the texture without furring the boards
- Wood decks — gray and tannin removed, then optional penetrating sealer or stain-ready prep
- Railings, steps and lattice included; furniture moved and reset
- Dock decking where accessible — ask at the estimate

Our Process
How We Clean & Seal a Deck
Composite, capped composite, Trex or wood — and whether an old stain or sealer is present. That decides pressure, cleaner and whether sealing is on the table.
Mildew and algae killed at the root with a deck-rated treatment, then rinsed at low pressure so the board surface stays intact.
Wood dries fully, then gets a penetrating sealer with written cure instructions — or we prep it clean for the stain of your choice.
✅ 90-Day Clean-Back Guarantee
If mildew visibly returns within 90 days of a deck clean, we re-treat that area free. In writing, on every work order.
