Pressure Washing & Roof Cleaning in Half Moon Bay, CA

Roof Soft Washing
Safe, low-pressure cleaning that kills moss, algae, and lichen at the root. Coastal roofs need this more than anywhere — fog and moisture accelerate growth dramatically. Results last 2–3 years.
House Washing
Stucco, wood, brick, and fiber cement siding cleaned with material-specific solutions. We remove salt residue, mildew, and biological growth without damaging paint or finishes.
Driveway & Hardscape Cleaning
Concrete, pavers, flagstone, and decorative hardscapes restored to like-new condition. Driveways, walkways, patios, and pool decks.
Gutter Cleaning
Complete gutter cleaning and debris removal. Coastal winds bring extra debris — we also install gutter guards to reduce maintenance and prevent water damage.
Window Cleaning
Professional exterior window cleaning for all types — single-story, multi-story, and architectural glass. Remove salt film and fog residue for crystal clear ocean views.
Deck Cleaning & Refinishing
Wood, composite, and Trex decks cleaned and restored. Coastal decks weather fast — we bring them back to life and protect them from salt air and moisture.
Solar Panel Cleaning
Restore up to 30% energy efficiency with professional panel cleaning. Salt spray and fog residue reduce output fast in coastal areas.
Patio & Fence Cleaning
Wood, stone, and masonry fences and patios carefully cleaned and restored. We remove years of coastal buildup without damaging surfaces.
⚠Ô∏è Protect Your Homeowners Insurance
Insurance companies across California are canceling policies based on visible roof moss, algae, and staining — using aerial and satellite imagery to inspect properties remotely. Over 2.8 million policies have been non-renewed in recent years. Coastal homes like those in Half Moon Bay are especially vulnerable to heavy biological growth that triggers cancellations. Professional roof soft washing removes these red flags and can prevent or reverse non-renewals. Proactive exterior maintenance isn't just cosmetic — it's financial protection.
