Siding Cleaning in Portland, ME
Soft washing for vinyl, fiber-cement, cedar, and aluminum siding — coastal Maine homes refreshed without damage to paint or trim.
Our Siding Cleaning Services in Portland
Vinyl, Aluminum & Fiber-Cement Siding
Salt air off Casco Bay leaves chalky oxidation on aluminum, green algae on north-facing vinyl, and mildew streaks under eaves. Our low-pressure soft wash dissolves and rinses them without etching the surface.
Vinyl: oxidation and mildew removal without warping
Aluminum: chalky residue lifted, original color restored
Fiber-cement (Hardie): safe for textured surfaces and painted finishes
Aluminum trim, soffits, and gutter exteriors
Wood & Cedar Shake Siding
Older Portland homes — especially in the West End, Eastern Promenade, and inland in Falmouth — often have cedar shake or painted clapboard that needs a gentler touch:
Painted clapboard cleaned without stripping or chipping paint
Cedar shake refreshed without forcing water behind individual shakes
Pre-stain prep — when you're planning to re-stain, we clean first
Bleach-free detergents on wood surfaces to preserve color
Brick, Stucco & Stone Exteriors
Brick and stone facades along Munjoy Hill and downtown Portland trap soot, salt residue, and organic stains. We use the right detergent and dwell time for each surface:
Brick: surfactant pre-treatment, low-pressure rinse — protects mortar joints
Stucco: gentle soft wash, never high pressure that can crack the finish
Natural stone facades and chimney bases
Historic facades — careful work where original tuckpointing remains

Coastal Maine homes need siding care a couple times a year. Here's what to think about between visits:
Plan a soft wash every 12–18 months on the coast — salt air mildews siding faster.
North-facing walls collect algae fastest — schedule those for spring after the last hard freeze.
Trim shrubs and trees touching siding to reduce moisture wicking and green algae buildup.
Don't pressure-wash bare wood, peeling paint, or older fiber-cement — soft washing is the safer call.

Siding Care Tips for Portland Homeowners
FAQs About Siding Cleaning in Portland
-
Coastal Maine homes do well with a soft wash every 12–18 months. Inland homes can stretch to 24 months. North-facing walls and homes under heavy tree cover mildew faster and may need annual attention.
-
Yes, when we use soft washing. We rely on low-pressure detergent application rather than high-pressure water, which protects paint, caulk, and original woodwork on older Portland homes.
-
Yes. Our gentle soft-wash technique lifts mildew and algae from cedar shake without forcing water behind the individual shakes or stripping the wood's surface.
-
Yes. Our detergents are formulated to break down salt deposits, oxidation, and the chalky residue that builds up on aluminum and vinyl siding from coastal exposure.
-
Spring through fall is ideal — we need temperatures consistently above freezing for our detergents to work. We typically book Portland siding cleanings April through late October.
-
Most single-family homes are a 2–4 hour job for a two-person crew. Larger homes, multi-unit properties, or homes with heavy mildew buildup may take a full day.
