Exterior Cleaning in Biddeford, Maine

Exterior Cleaning for Biddeford Homes

Biddeford is an old mill city on the Saco River, and its housing shows it. Around downtown and the mill district there are older multi-family buildings and houses with clapboard and painted trim. On the coast, Biddeford Pool, Hills Beach, and Fortunes Rocks are lined with shingled homes that face the open ocean. We handle soft washing, house washing, roof cleaning, gutter cleaning, and pressure washing across the city, and we pick the method to suit the surface.

Why We Soft Wash Instead of Pressure Wash

Soft washing is a method that relies on our special proprietary cleaning solution to kill organic matter rather than high pressure. While high pressure washing may appear to remove the moss, dirt and algae, it doesn’t kill it. By killing algae and fungus, your exterior surfaces remain clean longer than with a pressure wash. This method is commonly used for residential and commercial properties, as well as on surfaces like roofs, decks, and fences. With our high quality equipment and professional detergents, it is the safest and most effective method of cleaning exterior surfaces. 

On the coast, salt does the damage. Homes at Biddeford Pool and Fortunes Rocks take wind and spray straight off the Atlantic. Salt is hygroscopic, so it pulls moisture from the air and holds it against siding long after the weather clears, and that lingering dampness is what feeds algae and mildew season after season. Rinsing the salt film off is as important as treating the growth. Downtown, the older multi-family buildings have more siding, more trim, and more stories to cover, and grime and mildew build up on the shaded sides. Inland, wooded lots keep roofs damp enough for black streaking. The streaks are Gloeocapsa magma, a cyanobacteria that settles on north-facing planes first and feeds on the limestone filler in asphalt shingles, so leaving it alone costs granules and roof life.
