Away from the coast, the enemy is moisture. Shaded, damp areas of Cambridge homes grow a biofilm of pollen, algae, and mildew that thrives on north-facing and tree-side walls. Soft washing kills that growth at the root so it stays gone far longer than a quick rinse, while heavy spring pollen and winter road-salt grime get cleared in the process.
Soft Washing vs Power Washing in Cambridge
The single most important thing on any Cambridge job is matching method to material. Soft washing uses low pressure plus a cleaning solution that dissolves grime and kills algae, mildew, and moss at the source. It cleans deeper and lasts longer than pressure alone, because the growth is dead, not just knocked loose.
That means soft washing for siding, roofs, stucco, and cedar — roughly under 100 PSI on asphalt shingles, 100–500 PSI on vinyl, under 200 on cedar, and under 400 on historic brick — and true pressure washing (2,000–3,000 PSI with a surface cleaner) reserved for concrete and other hard surfaces. We confirm the right setting against each surface on site before any trigger is pulled.
Common Exterior Cleaning Issues in Cambridge
The New England climate creates predictable problems for Cambridge properties. We tackle them all:
- Black streaks (Gloeocapsa magma algae) and moss on asphalt-shingle roofs
- Green algae and mildew on north-facing siding, common on shaded Cambridge lots
- Slippery algae and mold buildup on shaded decks, patios, and pool decks
- Freeze-thaw cycles spalling brick, cracking joints, and lifting decking
- Cobwebs, dirt, and organic film collecting under eaves, soffits, and trim
Best Time to Pressure Wash in Cambridge
For Cambridge homes, late spring through early fall is the sweet spot. We like late May and June for siding — it removes the season's pollen and the previous winter's salt film together. Roofs and pool decks clean up well through dry summer windows, and concrete sealing is best done before the road-salt season returns. We avoid washing in freezing temperatures, when water can ice on surfaces and force its way into cracks.

Hiring a Pressure Washing Company in Cambridge? Read This First
One honest note for Cambridge homeowners: the lowest bid is often the most expensive. A price far below market rate usually means something is missing — workers' compensation, professional equipment, or experience — and the repair bill for stripped siding or a voided roof warranty dwarfs what you saved. Massachusetts doesn't issue a "pressure washing license," so the credential that actually protects you is insurance. Wash Bros is fully insured, with a certificate of insurance available on request.
Exterior Cleaning Tips for Cambridge Homeowners
Wash after peak pollen
Late May into June is ideal — it clears heavy oak and pine pollen plus early-summer mildew in a single visit.
Plan deck washing for early fall
Clean and seal wood decks before winter so freeze-thaw moisture can't work into the boards.
Insist on soft washing roofs & vinyl
High pressure voids shingle warranties and forces water behind siding. These surfaces should be soft washed, not blasted.
Pre-soak and cover landscaping
Watering shrubs and beds before service and shielding them during application protects your plants from cleaning solution.
