Homes on an Open Coast
Pressure washing in Cape Elizabeth means working on homes that face the open Atlantic. The town has more water than land within its borders: about 31 square miles of water against 14.7 of land. Wind off the Gulf of Maine carries salt and moisture across yards, decks and roofs, and the result shows up as a gray film on siding, green growth on shaded walls and black streaks on north-facing shingles.
People stay put here
Census figures show that about 88% of homes in Cape Elizabeth are owner-occupied and that 91.9% of residents lived in the same house a year earlier. Households average 2.55 people. Owners who stay this long tend to think about upkeep in terms of decades, not seasons. Cleaning that is too aggressive can strip paint, etch stone and roughen cedar, so our approach is built around protecting the surface for the long term, not just making it look clean today.
How we wash a house exposed to the sea
We soft wash. That means a cleaning solution suited to the siding is applied at low pressure, left to break down salt film, mildew and algae, and then rinsed off. Cedar shingles, painted clapboard and vinyl all respond well to it. High pressure on a house that takes wind-driven rain all winter can force water behind boards and trim; soft washing avoids that. We also rinse plantings before and after, which matters on properties where landscaping takes salt exposure already.
Roofs that grow algae
The dark streaks on many coastal roofs are algae, not dirt. They hold moisture and look worse every year. The Roof Cleaning Institute of America and the Asphalt Roofing Manufacturers Association both advise against pressure washing asphalt shingles because it knocks off the protective granules. Our roof soft wash treats the growth at low pressure and lets rain finish rinsing it away over the following weeks.
Stone, decks and outdoor living
A lot of Cape Elizabeth homes have bluestone or granite walks, stone walls, brick patios and large decks built to take in the view. Each gets its own treatment:
- Decks and railings: low-pressure cleaning that lifts gray, weathered fibers without tearing the grain, ahead of a new coat of stain or sealer
- Stone and brick: a mild cleaner and a wide spray, tested in a corner first
- Driveways and paths: cleaning of winter salt residue, tire marks and organic stains
- Fences and arbors: gentle washing of wood and vinyl
If part of your property is near conservation land or a wetland edge, tell us. We will plan where rinse water goes so it soaks into lawn rather than running toward the shore.
A town shaped by its shoreline
Cape Elizabeth separated from Falmouth on November 1, 1765, as Maine's 23rd incorporated town. Portland Head Light, first lit on January 10, 1791, was the first lighthouse built by the United States government. Its tower is rubblestone lined with brick, a reminder of how much stonework this coast holds. The town also includes Two Lights and Crescent Beach state parks, and Fort Williams Park, which the town acquired after the Army closed the fort in 1962. Owning a home near this much protected shoreline is a big reason people stay, and keeping the exterior in good shape protects that investment.
Timing your cleaning
The outdoor season on the coast is short, and fog and spring rain can push drying times out. We schedule house and roof washing for late spring through fall and keep a close eye on the forecast. Deck cleaning should be done several dry days before staining. Brick and stone should never be washed with water when frost is possible.

Cape Elizabeth Questions
Will soft washing hurt my cedar shingles?
Not when it is done correctly. Cedar is soft, and a high-pressure stream can fuzz or gouge it. Soft washing uses a cleaning solution at low pressure to remove mildew and salt film, then a gentle rinse. It is the method we use on shingle-sided homes along the coast.
How do you protect gardens on oceanfront lots?
We wet plants down before we start, cover delicate beds when needed, and rinse again afterward. We also keep the cleaning mix as mild as the job allows. Many coastal gardens already take salt stress, so we are careful not to add to it.
My roof has black streaks. Is it dirt or something else?
On the coast it is usually algae. It spreads on the shaded sides first. A roof soft wash kills the growth at low pressure without stripping granules, which is why we never pressure wash shingles. The streaks fade over the next few weeks of rain.
Can you clean my stone patio and walls?
Yes. We test a small, out-of-sight area first, then use a mild cleaner and low pressure so the stone face and joints are not worn down. We avoid washing stone or brick when frost is possible, since masonry can stay wet for days.
