Your home’s exterior is constantly under attack — not from storms or saltwater alone, but from silent invaders you can’t even see. Algae, mold, mildew, and pollutants quietly eat away at your roof, siding, and paint every single day. The good news? Soft washing stops the damage before it starts.
Here’s what’s threatening your Greenwich home right now — and how to fight back.
1. Algae That Eats Your Roof
Those black streaks on your roof aren’t dirt — they’re living organisms called Gloeocapsa magma. This algae feeds on the limestone in your shingles, weakening them over time and reducing your roof’s lifespan by years.
Soft washing removes algae at the root with low-pressure, eco-safe cleaners that protect your roof without voiding your warranty.
2. Mold That Feeds on Your Siding
Green and gray patches creeping up your siding? That’s mold — and it thrives in Greenwich’s damp, coastal air. It traps moisture against wood and vinyl, eventually leading to rot, warping, or cracking.
A professional soft wash not only removes visible mold but also eliminates spores hiding in surface pores and trim edges.
3. Pollen, Dirt, and Airborne Pollutants
Over time, invisible grime builds up like a film on your home. This layer dulls paint, stains trim, and accelerates fading. Pressure washing might blast it off temporarily — but it won’t stop it from coming back.
Soft washing actually neutralizes organic buildup, keeping your home cleaner for months longer.
4. Salt and Mildew from Coastal Air
Greenwich’s proximity to the Sound means salty mist and humidity coat surfaces year-round. Salt attracts moisture, which feeds mildew and corrosion.
Soft washing removes both salt residue and mildew before they damage siding, gutters, and metal fixtures.
5. The Real Cost of Doing Nothing
Delaying exterior cleaning can cost thousands in premature paint jobs, roof replacements, and repairs. Think of soft washing as preventive maintenance — a small investment that protects your biggest asset.
