Pressure Washing & Exterior Cleaning Services in Massachusetts

Our Pressure Washing & Exterior Cleaning Services

Wash Bros is a family-run exterior cleaning company started by brothers Louis and Dominic in 2023, and every job we take in Massachusetts comes down to one principle: you don't need more pressure, you need the right chemistry. A 4,000 PSI tip will strip the algae off your siding and the paint, the seal, and the surface texture right along with it. The smarter approach is to match the method to the material, dissolve growth at the root with biodegradable surfactants, and rinse gently. Below is how our full service range fits together, and how to pick the right one for your surface or your problem.

Residential vs. commercial: where to start

If you own a home, you're choosing between two camps. Most siding, roofs, and painted surfaces want a soft wash — a low-pressure application of cleaning solution. Hard, durable flatwork like concrete and pavers can take real pressure. We handle both sides of that on the residential menu, from a full house washing to deck cleaning, patio cleaning, fence cleaning, and pool deck cleaning.

On the commercial side, property managers and business owners deal in scale and liability. We run commercial pressure washing for storefronts, dumpster pads, gum removal, and degreasing, plus fleet washing, parking garage cleaning, HOA pressure washing, and apartment complex pressure washing. The difference isn't the equipment — it's scheduling around foot traffic, certificate-of-insurance requirements, and keeping a property looking maintained year-round.

Soft wash vs. power wash: which surface gets which

This is the decision that protects your property, so here's the plain version:

• Soft wash (under ~500 PSI). Vinyl, aluminum, fiber cement (Hardie board), wood siding, stucco, and every asphalt-shingle roof cleaning we do. The pressure only carries the solution; the chemistry kills the algae, mold, and mildew. High pressure on a roof voids shingle warranties and blasts off the protective granules — non-pressure cleaning is the only safe method.
• Higher pressure (1,500–3,000+ PSI). Concrete, asphalt, brick, and stone flatwork that can handle it — driveway cleaning, concrete cleaning, sidewalk cleaning, and paver cleaning with a flat-surface cleaner for even, streak-free results.
• Hot water and heat. Grease, oil, and gum need hot water pressure washing. Heat does what cold PSI can't, which is why restaurant pads and garage floors get it.

When in doubt, the surface decides — not the machine. If you'd rather just describe the stain, our power washing page walks through how we choose.

The Massachusetts problems each service solves

New England weather writes the maintenance calendar here. A few patterns we see constantly:

• Black streaks on roofs. That's Gloeocapsa magma, a hardy algae that feeds on limestone filler in asphalt shingles. Our algae removal and roof soft wash clear it at the root so it doesn't grow back in a season.
• Green and gray film on north-facing siding and shaded patios. Inland humidity, pollen, and tree cover across Worcester County, MetroWest, and the Pioneer Valley feed algae and mildew. Mildew & mold removal and a house wash handle it.
• Moss and lichen on shingles and north-side hardscape. Common under tree canopy; moss & lichen removal lifts it without tearing up the surface.
• Salt-air corrosion and oxidation. Coastal homes on the Cape, the Islands, and the North and South Shores fight chalky oxidation removal on siding and gutter brightening to clear those tiger-stripe streaks.
• Stains that won't budge. Rust removal, oil stain removal, efflorescence removal on brick and masonry, and graffiti removal each need a specific solution, not brute force.
• Brick, stone, and stucco. Our brick cleaning and brick & stucco cleaning are gentle enough for the historic colonials and Victorians this state is full of.

Rounding out the list: gutter cleaning to clear interior debris, exterior window cleaning for hard-water and screen buildup, post-construction cleaning, and paint preparation washing so new paint actually bonds.

Smart bundling saves you a trip

The crew is already on site, so combining services is where homeowners get real value:

• Gutters + house wash. We clear and brighten the gutters while the siding solution dwells.
• Roof + gutters. Soft-wash the roof, then clean what washes down into the gutters in one visit.
• Driveway + walkways + steps. One flatwork session covers the sidewalk cleaning and entry hardscape with the driveway.

Seasonal timing for New England

The window that matters is spring and fall, roughly 40–75°F. Spring clears the algae and salt that the freeze-thaw winter drove deep into porous surfaces; fall clears leaf tannins and growth before the next freeze. We avoid washing in a hard freeze and time solutions for humidity so they work, not evaporate. As a rule of thumb: house exterior annually, roof every one to three years, driveways and flatwork every six to twelve months.

Why a surface-matched, fully insured local crew matters

A national franchise reading a script can't tell salt-air oxidation from inland algae, and a uninsured weekend operator with a rented machine can leave you with etched concrete, streaked vinyl, or a voided roof warranty. Wash Bros is fully insured — certificate of insurance available on request — and we protect your landscaping, manage runoff, and use biodegradable surfactants that are safe around plantings and well water. We carry a 5.0 rating across 130 reviews because we treat your property like it's ours.

We clean across the state, from Boston and Worcester to the South Shore in Quincy and the North Shore in Salem.
