Your driveway isn’t just dirty. It’s covered in organic growth that’s slowly breaking down the surface. Your deck isn’t just stained—it’s harboring mold that makes it slippery when wet. Your siding isn’t just discolored—it’s losing years of life because contaminants are eating through the finish.
Professional pressure washing fixes all of that. You get surfaces that look newer, last longer, and don’t create safety hazards. If you’re selling, clean exteriors can add 2-5% to your property value and help your home move faster. If you’re staying, you’re preventing expensive replacements down the road.
The difference between DIY and professional work isn’t just how it looks when it’s done. It’s whether your surfaces get damaged in the process. High pressure strips paint, etches concrete, forces water behind siding, and kills plants. Soft washing uses low pressure and the right cleaning solutions to do the job without any of that risk.
We’ve spent over ten years cleaning homes and businesses around Assembly Square and throughout Somerville. We’re a family-owned company, and we’ve built our reputation on being thorough, reliable, and safe.
Safe matters here because Assembly Square is one of the most densely populated areas in New England. Families with kids and pets need cleaning methods that won’t leave toxic residue on driveways or patios. Business owners need their storefronts cleaned without damaging finishes or landscaping. That’s why we use eco-friendly, non-toxic products and soft washing techniques that get the job done without the collateral damage.
You’re not getting a crew that rushes through and moves on. You’re getting people who don’t miss spots and who actually care that the job’s done right.
First, we assess what you need cleaned and what condition your surfaces are in. Not everything gets the same treatment. Concrete driveways can handle more pressure than wood decks or vinyl siding. We figure out the right approach before we start spraying.
Next, we pre-treat surfaces with biodegradable cleaning solutions that break down organic growth—mold, mildew, algae, dirt. This is the step most DIY jobs skip, and it’s why soft washing results last two to three times longer than high-pressure blasting alone. The solution does the heavy lifting, not the pressure.
Then we rinse everything using low-pressure soft washing or controlled pressure washing, depending on the surface. We protect your landscaping, move anything that needs moving, and clean up completely when we’re done. You get a free estimate upfront, flexible scheduling that works around your life, and surfaces that look the way they should.

We handle driveways, patios, decks, fences, siding, walkways, and commercial storefronts. If you’re prepping for driveway resurfacing, we’ll get the surface clean so sealant actually bonds. If your deck needs restoration, we’ll strip away the grime and old stain so you can refinish it properly. Graffiti removal is part of what we do for business owners dealing with vandalism.
Assembly Square has a mix of older residential properties and newer commercial developments. Older homes often have wood siding or composite decks that can’t take high pressure without damage. Newer buildings have materials that look great but show dirt fast. Both need the right cleaning method, and that’s not something you can figure out by renting a pressure washer from a big box store.
Power washing and pressure washing get used interchangeably, but they’re not the same. Power washing uses heated water and is better for heavy grease or oil stains on concrete. Pressure washing uses unheated water and works for most residential jobs. Soft washing uses even less pressure and relies on cleaning solutions. We use whichever method fits what you need cleaned.
Cost depends on what you’re cleaning and how much square footage you’re covering. Driveways typically run between $150 and $300 depending on size and condition. Whole-house exterior cleaning can range from $300 to $600 or more for larger homes. Deck cleaning and restoration varies based on square footage and whether you need staining afterward.
We give free estimates so you know exactly what you’re paying before we start. No surprises, no upselling once we’re there. The price reflects the time, the equipment, the cleaning solutions, and the experience to do it without damaging anything.
Renting a pressure washer costs around $100 for the day, plus you’re buying chemicals and spending your entire Saturday doing something that might not turn out right. If you damage siding or strip paint, you’re paying a lot more to fix it. Professional service costs more upfront but saves you time, risk, and potential repair bills.
For most homes, yes. Soft washing uses low pressure and specialized cleaning solutions to kill mold, mildew, and algae at the root. It’s safer for vinyl siding, painted surfaces, wood decks, and roofs. The results last longer because you’re treating the organic growth, not just blasting it off temporarily.
Pressure washing works great for concrete, brick, and other hard surfaces that can handle higher PSI. Driveways, sidewalks, and some types of stone patios benefit from pressure washing because you need that force to remove embedded dirt and stains.
The key is knowing which method to use where. A lot of DIY jobs go wrong because someone uses too much pressure on a surface that can’t handle it. We’ve seen stripped paint, gouged wood, broken windows, and damaged siding from improper pressure washing. Soft washing avoids all of that while still getting everything clean.
Most driveways benefit from cleaning once a year, especially if you’ve got tree cover or your driveway stays shaded. Organic growth builds up faster in damp, shaded areas. If your driveway is in full sun and you don’t have major staining, you might stretch it to every 18 months.
Decks should be cleaned at least once a year before you reseal or restain them. If you’re not resealing regularly, cleaning every year still prevents buildup that makes the wood slippery and accelerates rot. Composite decks need less maintenance but still get dirty and grow mildew in humid climates like Massachusetts.
Waiting too long means contaminants have more time to break down your surfaces. Algae and mold aren’t just cosmetic problems—they actively deteriorate materials. Regular cleaning extends the life of your driveway, deck, and siding, which saves you money on premature replacement or major repairs.
It can if it’s done wrong. High pressure applied incorrectly will strip paint, force water behind siding, crack seals, and etch concrete. Vinyl siding is especially vulnerable because too much pressure can crack it or push water into your walls. Wood siding can splinter or lose its finish.
That’s why we use soft washing for most siding and adjust pressure based on the material we’re cleaning. Concrete and brick can handle higher PSI, but even then, you need the right nozzle and technique. Holding a high-pressure nozzle too close or at the wrong angle causes permanent damage.
We’ve been doing this for over a decade, and we know what each surface can tolerate. Our equipment is professional-grade with adjustable pressure settings, and our team is trained to recognize when something needs a gentler approach. You’re not risking your property when you hire people who know what they’re doing.
Yes, we use cleaning solutions, and yes, they’re safe. We specifically use eco-friendly, biodegradable products that won’t harm your kids, pets, or landscaping. The solutions break down organic growth like mold and algae, which is what makes soft washing so effective.
Before we start, we wet down plants and cover anything sensitive. After we’re done, we rinse everything thoroughly. The products we use are designed to be safe once diluted and rinsed, and they don’t leave toxic residue the way some harsh chemicals do.
This is a big reason families in Assembly Square choose us. You’ve got kids playing in the yard, dogs running around, and gardens you’ve spent time on. The last thing you want is someone spraying harsh chemicals that linger. We’ve built our reputation on being safe and thorough, and that includes the products we bring to your property.
Yes. Graffiti removal is something we handle for both residential and commercial properties. Depending on the surface and the type of paint or marker used, we’ll use a combination of pressure washing and specialty cleaning agents to lift the graffiti without damaging the underlying material.
Brick, concrete, and metal surfaces are usually straightforward. Painted or porous surfaces take more care because you don’t want to strip the original finish while removing the graffiti. We assess the situation first and let you know what’s realistic.
Old paint removal works the same way. If you’re prepping a surface for repainting or refinishing, we can strip old, peeling paint so you’re starting with a clean base. This is common for deck restoration projects where old stain needs to come off before applying a new coat. It’s detailed work, but it’s part of what we do.
