You’re not just removing stains. You’re eliminating the organisms causing them.
Massachusetts humidity creates the perfect breeding ground for algae, mold, and mildew on every exterior surface. That green tint on your siding isn’t dirt. It’s living growth that spreads, holds moisture against your home, and comes back faster every season if you only blast it away with high pressure.
Soft washing uses low-pressure water combined with biodegradable cleaning solutions that kill organic growth at the source. The result isn’t just cleaner surfaces. It’s surfaces that stay clean because the spores, roots, and colonies are actually gone.
Your driveway stops growing that slippery film. Your siding doesn’t streak green after every rain. Your deck doesn’t need scrubbing every spring. The difference isn’t cosmetic—it’s structural protection that saves you money on repairs and repainting down the line.
We’re a family-run business that’s been serving Powder House Square and the surrounding Somerville area for more than ten years. We’re not a franchise. We’re locals who understand what Massachusetts weather does to your property.
You’ll work with the same team from estimate to completion. We use eco-friendly products that are safe for your kids, pets, and landscaping—not because it’s trendy, but because we live here too. Our equipment is professional-grade, and our process is designed to clean thoroughly without causing the damage that high-pressure washing often leaves behind.
We’ve cleaned hundreds of triple-deckers, Victorian homes, and modern condos throughout Somerville. We know which surfaces need soft washing, which can handle more pressure, and how to handle the unique challenges of older New England construction.
We start with a free estimate where we assess your property and identify which surfaces need attention. Not everything gets the same treatment—your roof, siding, driveway, and deck all require different approaches.
Once scheduled, we pre-treat affected areas with our cleaning solution. This sits for a controlled period to break down organic growth, oxidation, and built-up grime. For soft washing, we use low pressure to rinse everything away without forcing water under siding or damaging surface textures.
For harder surfaces like concrete driveways or walkways, we use appropriate pressure levels that remove stains and buildup without pitting or scarring the material. We protect your landscaping, windows, and any vulnerable areas before we start.
The entire process typically takes a few hours depending on your property size. You’ll see the difference immediately—surfaces look brighter, colors come back, and that dingy film is completely gone. More importantly, you won’t see that growth return nearly as fast because we’ve eliminated it properly.

We handle full house washing for all siding types—vinyl, wood, fiber cement, and stucco. Each material has different tolerances, and we adjust our pressure and cleaning solutions accordingly. You get a clean exterior without the risk of water intrusion or surface damage that comes from improper technique.
Driveway and walkway cleaning removes oil stains, tire marks, and that black algae that makes concrete look aged. In Powder House Square, where many homes have shared walkways and front steps, this makes a noticeable difference in curb appeal and safety—wet algae is slippery.
We also offer deck and fence restoration, which goes beyond basic cleaning. We can remove old stain, prep the wood, and get it ready for refinishing. Graffiti removal is available for commercial properties or any surface that’s been tagged.
For businesses along Highland Avenue or near Davis Square, we provide storefront cleaning that removes street grime, exhaust residue, and weathering. Clean glass and fresh-looking facades directly impact foot traffic. Power washing is particularly effective for brick and concrete commercial buildings that accumulate years of urban buildup.
Pressure washing uses high-pressure water to blast away dirt and stains. Soft washing uses low pressure combined with specialized cleaning solutions to kill organic growth like mold, algae, and mildew at the source.
High pressure works well on concrete and stone, but it can damage softer surfaces like vinyl siding, wood, roof shingles, and painted surfaces. It can force water behind siding, strip paint, gouge wood, and even crack older mortar. It also only removes surface-level stains—it doesn’t kill the organisms causing them, so growth returns quickly.
Soft washing treats the problem, not just the symptom. The cleaning solution breaks down organic matter and kills spores, which means your home stays clean significantly longer. For most residential exteriors in Powder House Square—especially siding and roofs—soft washing is the safer and more effective choice.
Most homes in the Somerville area benefit from professional cleaning every 1-2 years. Massachusetts humidity accelerates organic growth, especially on north-facing surfaces that don’t get direct sunlight.
If your home is surrounded by trees, near water, or in a shaded area, you might notice algae and mildew returning faster. Some homeowners schedule annual cleanings in spring to reset their exterior before summer. Others wait until they see visible growth or discoloration.
The advantage of soft washing is that it extends the time between cleanings. Because we’re killing growth at the root rather than just rinsing it away, treated surfaces stay cleaner 4-6 times longer than traditional pressure washing. If you’ve been cleaning your home every year and still seeing quick regrowth, the method matters more than the frequency.
Traditional high-pressure washing is not safe for roofs. The force can dislodge shingles, strip protective granules, and force water under roofing materials where it causes leaks and rot.
Soft washing is specifically designed for roofs. We use very low pressure—about the same as a garden hose—combined with a cleaning solution that kills the black algae streaks (gloeocapsa magma) that grow on asphalt shingles. This removes staining without damaging your roof’s integrity or voiding manufacturer warranties.
Many roofing warranties explicitly prohibit high-pressure cleaning. Soft washing is the industry-recommended method because it’s effective and safe. If your roof has dark streaks or green patches, that’s organic growth that holds moisture against the shingles and accelerates deterioration. Removing it properly extends your roof’s lifespan and improves your home’s appearance and value.
It can, if done incorrectly. High pressure applied too close or at the wrong angle can crack vinyl siding, strip paint, force water into wall cavities, and damage caulking around windows and doors.
We use soft washing for all siding types, which eliminates that risk entirely. The low-pressure application is gentle enough for painted wood, vinyl, aluminum, and fiber cement, but the cleaning solution is strong enough to remove years of buildup, oxidation, and organic stains.
If your siding is already compromised—loose panels, failing caulk, or peeling paint—we’ll point that out during the estimate. Cleaning won’t fix existing damage, but it also won’t make it worse when done properly. For older Powder House Square homes with original siding, this approach protects your investment while still delivering a thorough clean.
Most full house washing projects in the Somerville area range from $500 to $900 depending on your home’s size, siding type, and how much growth we’re treating. Driveway cleaning typically runs $200 to $350.
We provide free estimates so you know exactly what you’re paying before we start. Pricing factors include square footage, surface accessibility, the level of buildup, and whether additional services like deck restoration or gutter cleaning are included.
Lower prices often mean corners are being cut—either in equipment quality, cleaning solutions, or technique. We’re not the cheapest option, and that’s intentional. You’re paying for proper equipment, eco-friendly products that actually work, and a team that knows how to clean without causing damage. That means fewer callbacks, no surprise repairs, and results that last years instead of months.
Yes. We use biodegradable, eco-friendly cleaning solutions that break down naturally and won’t harm your landscaping, pets, or family. We’re not using harsh acids or bleach-heavy mixtures that kill grass and leave chemical odors.
Before we start, we pre-wet your plants and cover any sensitive vegetation. After cleaning, we rinse thoroughly so no residue is left behind. Our solutions are designed to target organic growth—not damage the environment around your home.
This matters in Powder House Square where many properties have gardens, shared green spaces, and pets that spend time in yards. We’ve been using these products for over a decade with zero issues. You won’t smell harsh chemicals during or after the job, and your landscaping will look the same as it did before we arrived—just with a cleaner home behind it.
