Green algae creeping up your siding. Black mold streaks under the eaves. Mildew on the north-facing walls. Our gentle house washing removes it all safely from any siding type with a quality commitment.
Columbus homeowners often notice green algae appearing on the lower sections of their siding, black streaks forming under gutters and eaves, and a general darkening of north-facing walls. These are not just cosmetic issues. They are signs of active bio-growth that can cause structural damage if left untreated.
Green algae on siding retains moisture against the surface, accelerating deterioration of paint, caulking, and the siding material itself. Black mold and mildew can penetrate porous surfaces like wood and stucco. On vinyl siding, oxidation and bio-growth cause permanent staining if not treated promptly.
Pressure washing siding is a common DIY mistake that causes more damage than it fixes. High pressure forces water behind siding panels, damages caulking and trim, and can strip paint. Our gentle process applies a biodegradable solution at low pressure that kills bio-growth at the root without any of the damage that pressure causes. Our quality commitment applies to house washing just like it does to roof cleaning.
