Why Customers Choose Our Power Wash Team
Walker Painting has served Long Island since 1995 and has painted 12,000+ homes. Most Walker Painting painters have been with the company for 15+ years, so the crew that arrives is a vetted, long-tenured one. The company handles pressure washing before painting on most of its jobs. Every employee is reference-checked and has multiple references. Residential homeowners in Nassau County, Suffolk County, Queens and Manhattan call the same number, and the company is serving projects from a single deck to a whole house.
The company is licensed in Nassau and Suffolk counties and carries liability insurance for New York City work. It is also lead-safe certified for pre-1978 homes, which matters when washing touches old paint. Reviewers rate Walker Painting 5.0 stars across 300+ Google reviews, and phones are answered 24 hours a day, 7 days a week.
Power Wash Pricing and What Affects the Cost
The company has not published a fixed price for pressure washing, so this page gives no number. Cost moves with the size of your home, the type of surface, the amount of algae, mildew and grime, the height of the walls and whether roof edges and gutters are part of the job. Two houses of the same size can still differ in price.
Get a free on-site estimate, and it turns those factors into a quote for your home. Estimates carry no obligation, and you can request one by phone at 516-447-2732 or through the contact page. When you compare quotes, ask what each washing services price covers, such as cleaner, rinsing and the schedule. Payment terms and materials belong on that list, because the company has not published them here.
How Our Power Wash Process Works
The painter explains each stage at the estimate. A typical washing visit moves in this order.
- The painter inspects the surfaces and writes the estimate.
- The crew moves furniture and covers plants near the washing area.
- The crew rinses the dirt and debris off the surface first.
- The crew uses a cleaner where algae, mold or mildew shows.
- The crew rinses the cleaner away from the top down.
- The surface dries before painting, staining or sealing finishes go on.
- The painter walks the completed work with you.
When painting follows, every paint job carries a one-year written warranty against paint failure.
Power Washing: What the Service Actually Includes
The washing service covers pressurized water, a cleaner when the surface needs one and a rinse that carries the dirt away. It cleans siding, decks and concrete, and it prepares those surfaces for paint or stain. Walker Painting lists it as its own service.

Which Siding, Deck, Patio and Brick Surfaces We Power Wash
Surfaces people ask about include pressure washing for vinyl and wood siding, brick, stucco, concrete walkways, patio floors, a wood fence and a deck. The company has not published a washing surface list, so confirm yours at the estimate. Roof edges and gutters are worth raising too.

Power Wash Assessment and Estimate Planning
The painter checks your home’s surface material, the amount of buildup, the access to each wall and the weather. Those checks set the washing method, the schedule and the quote. Crews can start as early as the next day once you book an appointment. Ask about access and the hours the crew will be working.

Power Wash Methods for Vinyl, Wood, Stucco and Concrete Surfaces
Washing techniques vary by surface. Firm pressure suits concrete, while vinyl, wood and stucco take a gentler wash, because too much pressure puts the surface at risk of damage. A cleaner handles algae and mildew, and a plain rinse handles loose dirt. Ask which method your home needs.
Power Wash Aftercare for Siding, Decks and Gutters
After the washing, the surfaces need time to dry. Trimming plants back from the walls and clearing gutters helps keep algae and mildew from coming back. Check the shaded walls and deck of your home each season, and book another wash when green film or black streaks return.
Preparing Your Home, Deck and Yard for the Wash
Move cars, toys and furniture away from your home’s walls, close the windows and tell the crew where your outdoor water spigot sits. Walker Painting uses heavy canvas drop cloths on its painting jobs, and the same protection habit carries over to the washing prep.

How Power Wash Work Fits With Our Other Services
Washing is often the first step of a bigger job. Walker Painting offers house painting, exterior painting services, interior painting and commercial painting, including painting exterior walls and painting interior rooms. It also does wallpaper removal and installs wall covering, and its painters repair rotted wood, a structural problem a wash can reveal.

The part most painters skip is the part we’re known for
Prep, protection and paperwork. It is not glamorous, and it is the whole difference between a paint job that lasts and one that doesn’t.
Your home gets protected
We move everything to the center of the room, use casters so nothing scars the floor, and lay heavy canvas drop cloths, never plastic sheeting underfoot.
Lead-safe certified
We are a certified lead paint renovator and have completed the full certification coursework, which matters on almost every pre-1978 Long Island home.
One-year written warranty
Every paint job is covered by a one-year warranty against all paint failure. It is written down, and you get a copy.
Crews you can vet
Every employee is vigorously screened with multiple references. Most of our people have been with Walker Painting for 15 years.

Rated 5.0 across 300+ Google reviews
WOW, thank you to Sal and his team. The professionalism and flexibility working with Sal was like no other. We would happily refer them to anyone looking for a team of caring people who do a tremendous job.
They are fully staffed, which is rare.
Paula’s exterior came with significant rotted wood. The crew handled the repairs without delay, and leaned on Dave and Sal to pick shades that stayed true to her home’s classic traditional style.
Frequently Asked Questions About Washing
Should I tackle pressure washing of my deck, siding or patio on my own?
A do-it-yourself (DIY) wash can damage siding or wood when the pressure runs too high. Walker Painting offers the service, so get a free estimate for your home before you rent equipment.
How can I keep algae, mildew and dirt off my home between washes?
Trim plants back from your home’s walls, keep gutters clear and rinse dirt off the deck with washing as needed. Shaded walls grow algae and mildew first, so check those each season.
Do you provide a free estimate and a quote?
Yes. Washing estimates are free, on-site and carry no obligation, and the painter quotes the washing after looking at each surface.
Can power washing damage my vinyl siding, brick or stucco?
It can when the pressure is wrong for the material. The painter checks vinyl, wood, brick or stucco first, so ask how the crew sets the pressure for your home.
What weather suits pressure washing a deck, fence or concrete?
Dry, mild days suit washing, because surfaces must dry before painting or staining. Rain and freezing temperatures delay the work, so the crew plans around the forecast.
How much does it cost to pressure wash a home, deck or concrete patio?
The company has not published a price list. Request an estimate, and compare what each quote includes before you decide.
How long does power washing take for siding and gutters?
The company has not published a duration. The size of your home and the buildup decide it, so ask for a schedule at the estimate.
Do you handle surface preparation and peeling paint before painting?
Yes. Most houses that Walker Painting paints are power washed first, and the exterior painting workflow covers scraping, sanding, repairs, caulking and priming.
Which areas do you serve?
Walker Painting serves Nassau County, Suffolk County, Queens and Manhattan. Nassau County is the primary service area.
