Pressure Washing in Andover, MA
Affordable, dependable pressure washing and exterior cleaning for Andover, Massachusetts homes and businesses. 5.0-star rated, fully insured.
Wash Bros provides professional pressure washing and exterior cleaning throughout Andover, in the Merrimack Valley, and the surrounding towns. From algae-streaked siding to grimy driveways and black-stained roofs, we restore the look of Andover homes and businesses with safe, surface-appropriate methods — soft washing where it protects your property, higher pressure only where the surface can take it.
In Andover, humidity does the damage. Tree cover and shade keep walls damp, feeding green algae, black roof streaks, and moss that hold moisture against your home. We treat the growth with biodegradable solutions rather than blasting it, so your siding and roof are cleaned thoroughly and safely.
Soft Washing vs Power Washing in Andover
Here is the rule that protects your Andover property: you don't need more pressure, you need the right chemistry. Pressure does not kill algae or mold at the root — biodegradable surfactants do. High pressure only blasts the surface, and on the wrong material it forces water behind siding, strips cedar, or carves "zebra stripes" into concrete.
For your home that means soft washing the delicate surfaces — siding, roof shingles, stucco, painted wood, screens — and saving high pressure for driveways, sidewalks, and pads that can handle it. It's the same standard roof-shingle manufacturers require to keep a warranty intact, and it's how we clean every Andover property.
Common Exterior Cleaning Issues in Andover
The New England climate creates predictable problems for Andover properties. We tackle them all:
- Moss, lichen, and weeds taking hold in paver joints and shaded walkways
- Green algae and mildew on north-facing siding, common on shaded Andover lots
- Oil, rust, and tire stains spreading across concrete and asphalt driveways
- Cobwebs, dirt, and organic film collecting under eaves, soffits, and trim
- Freeze-thaw cycles spalling brick, cracking joints, and lifting decking
Best Time to Pressure Wash in Andover
Timing matters in Andover. The best window for house washing is late spring, from late May into June, after the heavy oak and pine pollen has fallen — so one wash clears pollen, winter road salt, and green growth at once. Decks and wood are best cleaned and sealed in early fall before freeze-thaw weather sets in, and driveways do well in spring or early fall. We work the whole season, roughly April through November, whenever temperatures stay above freezing.

Hiring a Pressure Washing Company in Andover? Read This First
Before you hire anyone in Andover, verify insurance. Exterior cleaning isn't a licensed trade in Massachusetts, so a company claiming to be "state licensed for pressure washing" is using marketing, not a real credential. What protects your home and the crew on it is general liability and workers' compensation coverage. Wash Bros carries full insurance and will share a certificate of insurance whenever you ask — and we'd rather earn the job than win it on the lowest, riskiest bid.
Exterior Cleaning Tips for Andover Homeowners
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.
Bundle gutters with house washing
Overflow from clogged gutters re-stains freshly cleaned siding within weeks. Cleaning both at once makes results last.
Ask about hot water for grease
For patios, dumpster pads, and oil stains, hot water cuts grease far faster and safer than cold water alone.
