Deck & Fence Cleaning in Bethesda, MD

A clean, well-maintained deck or fence is one of the most visible features of your outdoor living space. Unfortunately, wood and composite both face the same enemies in the Bethesda climate: UV exposure, humidity, mildew, algae, pollen, and the constant cycle of wet and dry. Within a single season, even a brand new deck can lose its color and pick up a layer of dirty green or gray film that ages it visually by years.

We approach decks and fences differently than driveways or siding. Wood is soft and easily damaged by aggressive pressure, so we use a low-pressure soft wash combined with wood-safe brighteners and cleaners. This system strips away mildew, algae, oxidation, tannin staining, and graying without raising the grain or splintering the surface. The result is a uniform, refreshed wood tone that's ready to stand alone or accept a fresh coat of stain.

For composite decking — including Trex, TimberTech, and Azek — we use composite-safe detergents that lift the chalky white film and stuck-on debris that build up between the boards. Pressure washing alone often makes composite look worse by leaving streaks and embedding dirt. Our chemistry-first approach delivers the bright, uniform look you expected when you originally invested in the deck.

After cleaning, many homeowners choose to add our staining and sealing service to lock in the renewed appearance and protect against future damage. Sealing wood after a thorough cleaning is one of the highest-return projects you can do for your outdoor space, and it dramatically extends the time between major restorations.
