A neglected deck becomes a safety hazard — algae-covered wood gets slippery fast, and ground-in grime accelerates weathering and rot. Our deck and patio washing service in Lancaster County restores wood, composite, and stone surfaces safely without stripping finishes or blasting through pavers.
Lancaster's warm, humid summers are ideal for deck use — and ideal for algae growth. Shaded decks and patios in Lititz, Manheim, and Elizabethtown can develop a visible green film within a single season. Wooded lots in Ephrata and Columbia accumulate tannin stains from leaf decomposition that turn wood gray and discolored over time.
We clean wood decks, composite decks, concrete patios, paver patios, and natural stone surfaces throughout Lancaster County. Each surface type requires a different approach — the same pressure and cleaning solution that works on concrete will damage a composite deck. We match the method to the material every time.
Pressure washing wood decks requires restraint. Too much pressure opens wood grain and causes fuzzing, splintering, and premature weathering. We use lower pressure with a wide-fan nozzle and follow the wood grain to clean effectively without damaging the surface. Pre-treating with a wood-safe cleaning solution breaks down algae, mold, and tannin staining before the rinse pass.
A clean deck also prepares the surface properly for staining and sealing — if you're planning to refinish your deck this season, our cleaning service is a logical first step. We recommend letting the wood dry for 48–72 hours after washing before applying any stain or sealer.
Composite decks require soft washing — high-pressure washing can void manufacturer warranties and damage the surface finish. We use low-pressure application of composite-safe cleaning solutions to remove algae, mold, and grime without harming the material. Many Lancaster homeowners are surprised how much cleaner their composite deck looks after a proper soft wash.
Concrete patios handle higher pressure well. Paver patios require more care — high pressure can displace joint sand and damage the finish on certain paver types. We assess your specific paver type before starting, use appropriate pressure, and restore joint sand after cleaning if needed.
