House Washing Services Long Island, NY

What House Washing Actually Does for You

House washing removes the layer of grime, mold, mildew, and algae that builds up on your siding over time. In Suffolk and Nassau Counties, our coastal humidity creates perfect conditions for that green and black growth you see on north-facing walls and shaded areas. Left alone, those organisms don’t just look bad—they feed on your siding and shorten its lifespan. A proper house wash brings your exterior back to the way it’s supposed to look. It protects your investment, boosts curb appeal, and stops organic growth before it causes real damage. We use soft washing for vinyl, wood, and stucco siding because high-pressure methods can strip paint, dent surfaces, or force water behind your panels.

Soft Wash vs Pressure Wash

Why We Don't Blast Your Siding

There’s a reason we use soft washing for house siding. High-pressure washing might seem faster, but it causes problems. Water forced at 2,500+ PSI can strip paint, dent vinyl, crack fiber cement, and push water behind your siding panels where it creates mold and rot you can’t see. Soft washing uses low pressure—about the same as a garden hose—combined with cleaning solutions that actually kill mold, mildew, and algae at the source. The result lasts longer because we’re not just blasting dirt off the surface. We’re treating the organic growth that keeps coming back. We’ve seen what happens when unlicensed operators show up with a pressure washer and no training. Stripped siding. Broken seals. Water damage inside walls. That’s not maintenance—that’s creating repair bills. Our crews know which surfaces can handle pressure and which ones need a gentler approach. Your vinyl siding, wood trim, and painted surfaces get soft washed. Your concrete, pavers, and brick get the pressure they can handle.

House Wash Process and Coverage

What's Included When We Wash Your House

We clean all your exterior siding, trim, soffits, and fascia. That includes the areas most homeowners can’t safely reach—second stories, peaks, and spots that require ladders and proper equipment. We’re not just hitting the easy parts and calling it done. Before we start, we protect your landscaping and check for any areas that need special attention. Then we apply our cleaning solution to break down the mold, algae, and built-up grime. After it does its work, we rinse everything with low-pressure water that won’t damage your siding but will leave it actually clean. If we spot issues during the wash—damaged siding, failing caulk, areas that need masonry repair—we let you know. A lot of our customers appreciate that heads-up because it lets them address small problems before they become big ones. And because we handle multiple exterior services, you can often get those repairs done in the same visit instead of waiting for another contractor.

House Washing FAQs

Common Questions About Our Service

How often should I have my house washed in Long Island?

Most homes in Suffolk and Nassau Counties benefit from house washing once a year. If your property is close to the water, surrounded by trees, or has a lot of shade, you might need it more often—maybe every 8 to 10 months. The coastal humidity here creates ideal conditions for mold and algae growth, especially on north-facing walls and areas that don’t get much sun. You’ll know it’s time when you start seeing black streaks, green stains, or that dingy film that makes your siding look older than it is. Regular washing isn’t just about appearance—it actually extends the life of your siding by removing the organic material that breaks it down over time.

Will pressure washing damage my vinyl siding?

Yes, if it’s done wrong. High-pressure washing can crack vinyl, strip paint, dent surfaces, and force water behind your siding where it causes mold and rot. That’s why we use soft washing for siding—it’s a low-pressure method that cleans just as effectively without the risk. Soft washing combines gentle water pressure with cleaning solutions that kill mold, mildew, and algae at the source. The results last longer because we’re treating the problem, not just blasting it temporarily. Pressure washing has its place—we use it on concrete, pavers, and other hard surfaces that can handle the force—but your siding deserves a safer approach.

What's the difference between power washing and soft washing a house?

Power washing uses high-pressure water to blast away dirt and grime. It works great on driveways, walkways, and concrete, but it’s too aggressive for most siding. Soft washing uses low pressure—similar to a garden hose—combined with specialized cleaning solutions that break down mold, algae, and mildew. The chemicals do the heavy lifting, so we don’t need force that can damage your home. Soft washing is safer for vinyl, wood, stucco, and painted surfaces. It also lasts longer because we’re killing the organic growth instead of just pushing it around. We use both methods depending on what we’re cleaning, but for house siding, soft washing is the right call.

Can house washing remove black streaks and green algae from my siding?

Yes. Those black streaks are algae, and the green stains are usually algae or moss. Both thrive in Long Island’s humid climate, especially on shaded or north-facing walls. Our soft wash process uses cleaning solutions designed to kill that organic growth at the root, not just rinse it off temporarily. Once we treat and rinse your siding, those stains come off and stay gone longer than they would with plain water or pressure alone. If the growth has been there for years, it might take a bit more attention, but we’ve handled plenty of homes where owners thought the staining was permanent. It’s not—it just needs the right approach.

Do I need to be home during the house washing service?

Not necessarily, but many homeowners prefer to be around, at least at the start and finish. We’ll do a quick walkthrough before we begin to point out any areas of concern and make sure we’re on the same page about what’s getting cleaned. At the end, we’ll show you the results and answer any questions. If you can’t be home, that’s fine too—we just need access to water and the ability to move anything that might be in the way, like patio furniture or potted plants. We’ll communicate with you ahead of time so you know exactly what to expect and when we’ll be there.

Is house washing safe for my landscaping and plants?

Yes, when it’s done correctly. We take steps to protect your landscaping before we start. That means pre-wetting plants, covering delicate areas if needed, and using cleaning solutions that are safe when properly diluted and rinsed. Our soft wash method uses less pressure, which means less splashing and overspray compared to aggressive pressure washing. We’re not careless with your property—your plants, mulch, and garden beds get the same attention and respect as your siding. If you have specific concerns about certain plants or areas, just let us know and we’ll take extra precautions.
