Every surface, one crew.
Each surface has its own page: what it involves, how it's done, and what it costs.
What exterior cleaning includes.
Exterior cleaning, or house washing, is two methods matched to the surface. Soft washing is a low-pressure rinse with a cleaning solution that kills algae and mildew at the root — for siding, roofs and cedar, which high pressure would crack or strip. Pressure washing is for the concrete, pavers and stone that can take it.
Pick one surface or the whole house. For homes and businesses across Suffolk County.

Walk around the house.
Long Island winters leave the same six problems on most homes — moisture, shade and tree cover do the rest. Here’s what to look for, and what fixes it.
Green on the siding
Algae, usually on north-facing walls and under the gutters, where moisture and shade let it grow. Soft washing kills it without damaging the siding.
Black streaks on the roof
Algae that thrives in humid air, running down the shingles from the peaks. Roof cleaning is a soft wash — never pressure.
Gutters overflowing
Winter storms fill them with leaves and sticks; the overflow stains the siding below. Gutter cleaning clears and flushes them.
A darkened driveway
Dirt, algae and tire and oil marks on concrete and walkways. Pressure washing is made for hard surfaces.
Slippery patios and grey decks
Algae on pavers and wood makes them look dirty and turn slick after rain. Pressure washing at the right setting for the material.
Cloudy windows
Dirt, salt residue and water spots left by winter storms. Window cleaning covers the glass, screens and frames.
How often, and when.
Most homes need an exterior cleaning every 1 to 2 years. Houses under heavy tree cover, or with shaded, damp sides, go green sooner.
Spring and early summer are when most people book, once winter has left its dirt, algae and debris behind. Gutters run the other way: they’re a fall job, after the leaves come down.
Typical intervals
- SidingEvery 1–2 years.
- Roofs and cedar shakeEvery 1–3 years.
- Driveways, patios, walkwaysAbout once a year, ideally spring.
- GuttersWhenever they fill — fall, and again after winter storms.
Green outside, black inside?
Algae is a cleaning job. Mold isn’t.
What it costs.
There’s no flat price: a single-story ranch with a short driveway and a three-story shingle house with a paver patio aren’t the same job.
Free estimate. The price you’re quoted is the price you pay.
Size and height of the house
Square footage, number of stories and roof pitch decide how much equipment and time the job needs.
Which surfaces
Siding alone is a smaller job than siding, roof, patio and gutters together — choose one surface or the whole house.
How much growth and staining
A season's algae rinses off faster than years of mildew, moss and ground-in stains.

Frequently asked questions
Straight answers on cost, timing and methods.
How much does exterior house cleaning cost?
There's no flat price — it depends on the size and height of the house, which surfaces you want cleaned, and how much growth and staining there is. The estimate is free, and the price you're quoted is the price, with no hidden fees.
What does exterior cleaning include?
Whatever the outside of the house needs: siding (vinyl, brick and stone), roofs and cedar shake are soft-washed; driveways, patios, pavers and decks are pressure-washed; gutters are cleaned by hand and flushed; and windows are cleaned outside. You choose the surfaces — one or all of them.
What is cleaning the outside of a house called?
Exterior cleaning, or house washing. It's done two ways: soft washing, a low-pressure rinse with a cleaning solution that kills algae and mildew, for siding, roofs and cedar; and pressure washing, for hard surfaces like concrete and pavers.
How often should a house exterior be cleaned?
Every 1 to 2 years for most homes, depending on tree cover and moisture. Roofs and cedar shake usually every 1 to 3 years, driveways and patios about once a year, and gutters whenever they fill.
When is the best time of year?
Spring and early summer are the most common, because winter leaves dirt, algae and debris behind. Gutters are the exception — fall, once the leaves are down.
Can pressure washing damage my house?
Yes, on the wrong surface. High pressure cracks siding, strips paint, loosens shingles and forces water behind panels. That's why siding, roofs and cedar are soft-washed and pressure is kept for concrete and stone.
Do you clean commercial properties?
Yes — homes and businesses across Suffolk County.
