Why Patios Get So Dirty on Long Island
Long Island's climate creates ideal conditions for outdoor surface contamination. Our warm, humid summers promote rapid algae and mold growth. Overhanging trees — common in neighborhoods like Bayport, Great River, and Holbrook — drop organic matter that stains surfaces and feeds biological growth. Road runoff and salt air from the South Bay contribute to additional buildup.
Left uncleaned for more than a season or two, patio surfaces can develop a slippery algae coating that creates a genuine slip-and-fall hazard. Regular annual or biannual patio cleaning isn't just cosmetic — it's a safety issue for your family and guests.
Deck Washing: What You Need to Know
Wood and composite decks require special care. Too much pressure can splinter wood, raise the grain, or damage composite material warranties. Our deck washing approach uses:
- Wood-safe cleaning solutions that kill mold without bleaching out the wood fibers
- Controlled, appropriate pressure for the deck's material and age
- Even, overlapping passes to avoid lap marks
- Post-wash inspection to identify any boards that may need repair before sealing

Pool Deck Cleaning
Pool decks around Long Island require extra attention. Constant water exposure, algae growth, and sunscreen residue create a stubborn buildup that's also a slipping hazard. We regularly clean concrete, pavers, and travertine pool decks across the region and can handle the scale of both residential and HOA common areas.
Spring Cleaning Tip: The best time to clean your Long Island patio is mid-to-late April, just as outdoor entertaining season begins. Book early — spring is our busiest season and schedules fill up fast across Sayville, Bohemia, and surrounding towns.
