Green film on shaded walls
Algae on the north side of a house or under trees holds moisture against siding, breaking down the paint film and inviting rot at the laps.
Exterior Painting in Quincy
Pressure washing and soft washing for Quincy siding, porches and granite steps

Quick answer
Pressure washing in Quincy covers cleaning siding, trim, porches, decks, fences, walks and granite steps with the right method for each: soft washing with a mild cleaner and a low-pressure rinse on clapboard and cedar shingles, higher pressure only on concrete and sound masonry. Typical ranges run $0.31 to $0.73 per square foot of surface. The walk-through sets the real number.
What pressure washing covers with us
The words pressure washing cover two very different jobs. True pressure washing uses a concentrated stream at high pressure and suits concrete walks, driveways, granite steps and some sound brick. Soft washing applies a cleaning solution that kills mildew and algae at the root, then rinses it away at little more than garden hose pressure. On an old wood house in Wollaston or Merrymount, soft washing is almost always the correct method.
We wash houses as the first step of exterior painting, and as a stand-alone service for homeowners and landlords who want siding, porches and walks cleaned between paint cycles. Before we start, we look at the siding type, the condition of the paint, caulk joints, window glazing and any spots where water could be forced behind the cladding. Then we choose a method and pressure for each surface rather than running one setting around the whole house.
When is it time to pressure wash or soft wash your Quincy house?
Black spots on porch ceilings
Mildew thrives on sheltered surfaces that rain never rinses, such as porch ceilings, soffits and the underside of eaves on two-family porches.
Gray haze on bay-facing walls
A dull, slightly gritty film on the sides facing the water is often salt and fine sand, and it should come off before any primer goes on.
Chalk on your hand
Rub the siding. If a colored powder comes off, the paint surface has broken down and must be washed off before new paint will bond.
Slick walks and granite steps
Algae and moss on concrete walks, brick paths and granite steps get slippery in wet weather and after the first frost, a real fall hazard.
Planning an exterior repaint
Every exterior paint job should start with a thorough wash. New paint over dirt, salt, chalk or mildew fails early, regardless of the paint brand.
Soft washing versus pressure washing on old clapboard and cedar shingles
High pressure on 100-year-old clapboard does real harm. A narrow spray can drive water up under the laps and into wall cavities, gouge soft pine and cedar, strip sound paint along with the loose paint, and push water past old window glazing. On cedar shingles it shreds the surface fibers and leaves a furry texture that grays faster. That damage shows up months later as peeling paint and stained plaster inside.
Soft washing avoids all of that. We apply a diluted cleaner with a low-pressure pump, let it dwell for several minutes to break down mildew, algae and dirt, then rinse from the top down at low pressure. Because the cleaner kills the organisms instead of just blasting the surface, the siding stays clean longer. Loose paint that comes off during a soft wash was ready to fail anyway, and we scrape it during prep.
- Soft wash: clapboard, cedar shingles, painted trim, porch ceilings
- Low to medium pressure: vinyl and aluminum siding, sound decks
- Higher pressure with a surface cleaner: concrete walks and driveways
- Measured pressure on granite steps, walls and curbing
- Gentle masonry wash: old brick with soft lime mortar
Cleaning solutions, rinse water and protecting plants during a wash
Our house wash mix is a diluted sodium hypochlorite solution with a surfactant that helps it cling to vertical walls, adjusted in strength for how heavy the growth is. On wood decks and fences, we switch to oxygen bleach and oxalic brightener, which are gentler on wood fibers. Rust stains from gutters and nails get a separate rust remover so the rest of the wall isn't overtreated.
Before any cleaner goes on, we soak plants, shrubs and lawn edges with plain water so their leaves don't absorb the mix. Sensitive plantings get covered. We rinse them again during and after the wash. Outlets, light fixtures, doorbells and dryer vents are taped and bagged, windows are closed and checked, and we point the rinse away from open soffits and attic vents.
Why salt film near the water changes how we wash and when we paint
Houses within a few blocks of Quincy Bay, Wollaston Beach and the Neponset River mouth collect a fine salt film every time the wind comes off the water. Salt draws moisture, so paint over it stays damp at the bond line and blisters early. We add an extra fresh-water rinse on the water-facing walls and check that the surface feels clean, not gritty, before we call it done.
When washing is prep for paint, we're a bit more aggressive on loose and chalking paint so the scraper and primer can do their work, and we leave the house to dry for two or three days before any coating. Chalky paint is a powder left by ultraviolet breakdown, and paint applied over it peels. A proper wash removes most of it, and we follow with a chalk test before priming. Routine washing every two or three years, without painting, keeps mildew from eating into the paint film and stretches the time between repaints.
How a house washing visit runs from setup to final rinse
Surface check
We walk the house, identify siding and trim materials, note loose paint, failing caulk and fragile glazing, and decide the method and pressure for each surface.
Protect and seal
Plants are soaked or covered, outlets and fixtures are bagged, windows and doors are closed, and cars and outdoor furniture are moved out of the spray zone.
Apply cleaner
The cleaning solution goes on from the bottom up so it doesn't streak, then dwells for several minutes while it breaks down mildew, algae and grime.
Rinse top down
We rinse from the roofline downward at low pressure, carrying dirt and cleaner off the walls and away from foundations, vents and window frames.
Flatwork and stains
Concrete walks, driveways and granite steps get a surface cleaner at suitable pressure, and rust or gutter streaks receive a separate spot treatment and rinse.
Final rinse and check
Plants get a last rinse, covers come off, and we walk the house with you to check for missed areas and any paint that came loose.
What pressure washing costs for a house in Quincy
Typical range in Quincy$0.31 to $0.73per sq ft of surface
The range covers soft washing siding and trim or pressure washing flatwork, with protection of plants and fixtures. A typical Quincy single-family or two-family, porches included, often falls near the middle. The walk-through sets the real number.
What moves the number
- Total square footage of siding, plus porches, decks, fences and walks added
- Height and access, since two-families and triple-deckers need longer reach and more care
- How heavy the mildew, algae and salt film are on shaded or bay-facing walls
- Siding type, from fragile cedar shingles to vinyl and brick
- Rust and gutter stains that need a separate treatment
- Number of plants, fixtures and parked cars to protect on a tight lot

Why Quincy houses near the bay grow mildew and hold salt so quickly
Quincy wraps around the bay, so a lot of the city lives with damp air. Morning dew sits on siding into midmorning, fog rolls in along Quincy Shore Drive and summer humidity rarely breaks for long. On the tight lots of Wollaston, North Quincy and Montclair, two-families shade each other and the side walls barely see sun. Out on Houghs Neck, Squantum and Adams Shore, shingled cottages take wind-driven salt as well. Those conditions feed green algae and black mildew on north faces, porch ceilings and the lower courses near the ground.
Much of the housing is old clapboard or cedar shingle, some covered later with vinyl or aluminum, and the original siding and glazed sashes can't take high pressure. Paint on pre-1978 houses is presumed to contain lead, so we don't blast it off. Any loose paint is handled with lead-safe scraping, ground sheeting and cleanup. Our washing season follows the exterior painting season in eastern Massachusetts, roughly May through October.

Pressure Washing questions from Quincy homeowners
Is pressure washing safe for the original clapboard on a Wollaston two-family?
Not at high pressure. Old clapboard can be gouged, water can be forced behind the laps and into the wall, and sound paint gets stripped with the loose. We soft wash wood siding with a cleaning solution and a low-pressure rinse instead. It cleans as well or better and kills the mildew rather than just knocking it off the surface.
How long after pressure washing a Quincy house can the painting start?
We wait at least two to three dry days before priming or painting. Wood siding absorbs some rinse water, and paint applied to damp wood blisters or peels. In humid stretches near the bay we check with a moisture meter before starting. The wait also lets us spot any paint that loosened during the wash so we can scrape it.
Will soft washing hurt the shrubs and gardens around a Merrymount house?
Our process is built around protecting them. We soak plants with clean water before the cleaner goes on, cover the most sensitive ones, keep the solution diluted, and rinse plants again during and after washing. Leaves already full of water absorb little of the cleaner. Minor tip browning on a very sensitive plant is possible, and we point those out beforehand.
Can pressure washing remove peeling paint from a pre-1978 Quincy Point house?
It will knock off some loose paint, but it shouldn't be used as a paint stripper. High pressure damages wood and, on houses built before 1978, spreads lead-containing chips and water across the yard and onto the house next door. Loose paint should be scraped by hand with lead-safe practices: misting, ground sheeting, collecting chips and HEPA cleanup.
How often should a shingled house on Houghs Neck or Squantum be soft washed?
Every two years suits most houses close to the water, where salt and mildew build up faster, while sheltered inland lots in West Quincy can often go three. Washing before mildew gets established keeps the paint or stain film healthy longer and delays the next repaint. Many owners pair it with porch and walk cleaning each spring.
