Complete Exterior House Washing on Long Island
Your home is likely your biggest investment. On Long Island, that investment faces year-round assault from humidity, salt air, pollen, mold spores, and temperature extremes. Over time, even the best-maintained homes develop green algae streaks, black mold patches, and a general dinginess that makes them look decades older than they are.
Best Power Wash LI's house washing service reverses all of that. Using our professional soft wash technique, we clean every exterior surface — siding, soffits, fascia, gutters, window frames, and trim — without any risk of damage. Your home looks like the day it was built.
What's Included in Our House Wash
- All siding surfaces — front, back, sides, dormers, gables
- Soffits & fascia — the overhangs and trim pieces most people forget
- Gutter exteriors — those black "tiger stripes" on gutters disappear
- Window frames & trim — every detail gets attention
- Foundation walls — the lower section that collects splashback dirt
- Under-deck areas — if accessible, we clean these too
Everything from ground to roofline gets cleaned. We don't do corners-only or quick-rinse jobs — your entire home gets the full treatment.
Our House Washing Process
We start with a thorough walkthrough, noting every surface type, problem area, and concern. All landscaping is pre-rinsed and protected before cleaning begins.
Our biodegradable cleaning solution is applied at low pressure from bottom to top, ensuring complete coverage. The solution penetrates organic growth and kills mold, mildew, and algae at the root — not just on the surface. After appropriate dwell time, a gentle low-pressure rinse from top to bottom reveals your clean home.
The entire process typically takes 2-4 hours for an average Long Island home. Larger homes or severely stained properties may take longer.
Siding Types We Clean
- Vinyl siding — Long Island's most common siding; soft washing removes green algae and black mold safely
- Wood siding & cedar shakes — cleaned without splintering or raising grain
- Stucco & EIFS — our solution penetrates porous surfaces for deep cleaning
- Brick — removes algae, efflorescence, and environmental staining
- Stone — natural and manufactured stone cleaned without damage
- Fiber cement (Hardie board) — safely cleaned and restored
- Composite & engineered siding — treated with appropriate solutions
Why Regular House Washing Matters
Beyond curb appeal, regular house washing protects your home's structural integrity. Mold and algae don't just sit on siding — they feed on it. Left unchecked, organic growth causes premature paint failure, wood rot, and permanent staining that no amount of cleaning can reverse. The cost of annual house washing is a fraction of repainting or re-siding.
For Long Island homeowners considering selling, a professional house wash is one of the highest-ROI improvements you can make. A clean exterior can add perceived value far exceeding the cost of the service.
What Affects House Washing Cost?
- Home size & stories — more surface area and height means more time and product
- Siding type — some materials require adjusted techniques
- Severity of growth — heavily stained homes need stronger solution and more dwell time
- Accessibility — steep lots, dense landscaping, or limited access adds complexity
- Add-on services — combine with roof cleaning, driveway washing, or deck cleaning for bundle savings
