Prizm Exteriors' top priority is becoming the most-trusted pressure washing company in the Merrimack Valley, and we've got the drive, determination, know-how, and customer-centered philosophy to make it happen. We match and exceed the standards of corporate-run pressure washing companies, but provide a more personal, one-on-one work relationship that revolves around our core philosophy of courteous, attentive service.

Prizm Exteriors is your Merrimack pressure washing choice when you want the highest quality pressure washing "before and after" transformations. We're the pressure washing company you can trust with tough jobs like driveway and commercial cleaning, or jobs that require more finesse and soft washing skills like house washing, roof cleaning, gutter, and window cleaning.

For premier personal and professional service, Prizm Exteriors is the Merrimack Valley's preferred pressure washing company.

House Washing

We've got the high PSI, heavy-duty, commercial-grade equipment for brick, block, and concrete houses and the low-pressure and no-pressure, chemically assisted, soft washing processes for wood, stucco, and vinyl siding. Prizm Exteriors will bring the maximum clean to your New Hampshire home with zero damage, even if you live in a glass house.

Roof Cleaning

Regular roof cleaning is a smart, cost-effective way to extend the life of your roof. We can clean and protect your roof and help you avoid the high cost of roof-replacement while avoiding damage to fragile shingles with our soft washing process.

Deck & Fence Cleaning

Whether you're improving the look of your patio, deck, or fence for backyard barbeques and entertaining, or preparing for painting, staining, or weatherproofing, we've got the equipment and expertise to do the job right. We will remove built-up algae and dirt from your wooden fences and decking to bring them back to life using low pressure and biodegradable chemicals to avoid damage.

Concrete Cleaning

We utilize cutting-edge technology and eco-friendly cleaning solutions that penetrate porous concrete at a molecular level and root-out tough oil, rust, and grease stains, restoring your driveways, sidewalks, and parking lots to their original pristine appearance. Prizm Exteriors has the tools, technique, determination, and training for the toughest stains and surfaces.

Gutter Cleaning

Your home's gutters protect your home's foundation, and no one wants foundation issues, so it's important that your gutters are always functioning properly. Gutter cleaning is a lot trickier than you would think and an amateur can often end up causing additional problems, so it's a smart move to trust a professional with the important chore of gutter cleaning.

Window Cleaning

Broken windows are the most common type of damage done by amateur and DIY pressure washers, so it's always best to hire a pro. You can trust Prizm Exteriors to treat your windows with TLC and have them looking as clean and transparent as when they were first installed.

Commercial Pressure Washing

Your business's first-impression begins in your parking lots, sidewalks and storefronts, and extends to your interior spaces. Unsightly stains, wear, and discolorations are a blemish on your business's brand. You can trust Prizm Exteriors for dependable, personalized service and to keep your business property always looking its best.
