Make your upstairs livable again this summer.

If your second floor hits 85° while the thermostat reads 72°, your AC isn't broken. Your insulation is. Spray foam stops the New England summer heat at your roof before it ever turns into a $400 electric bill or another sleepless night upstairs, and keeps your heat inside come winter.

Summer in a Massachusetts home

By peak summer, your AC has already lost the fight.

On a 90° day, your attic hits 140°. That heat doesn't stay up there. It radiates down into the rooms your family is trying to sleep in. Spray foam is the only insulation that actually stops it, in every season.

Peak-summer bill doubled

Eversource and National Grid rates keep climbing, and an unsealed attic forces your AC to run twice as long for half the comfort.

Bedrooms 10° hotter upstairs

You set the thermostat to 70° downstairs and the kids' rooms still read 82° at bedtime. Cranking it lower doesn't fix it. Sealing the attic does.

Sticky, humid air inside

New England humidity sneaks in through every gap in your envelope. Your AC can't dehumidify air it can't reach in the first place.

AC running nonstop

If your compressor is running 18+ hours a day during a heat wave, it's not just expensive. You're shortening the life of a $7,000 system.

Our services

Spray foam done right, for every space in your Mass home.

From the attic baking above your bedroom to the warehouse running your business, we install spray foam that keeps every space comfortable through every season. Cool when it's 95° out, warm when it's 15°, and a lot cheaper to run year-round.

  • Even temperatures upstairs
  • Lower heating & cooling bills

  • Warm floors year-round
  • Stops humidity, mold & pests
  • Healthier air inside your home

About Patriot

Built in a Rockland garage. Trusted in homes across Mass.

Our owner started Patriot Spray Foam Insulation in 2016 with a simple idea: Massachusetts property owners deserved a crew that cared about their home as much as they did. After the training, the certifications, and the hands-on hours, he built the company on his own terms.

He still runs every job alongside the team today. Same owner on your site, same crew on the next street over. That's what locally owned actually looks like.

Integrity

Honest, transparent, dependable. If something isn't right, we say so before we sell it to you.

Customer first

Your home, your timeline, your call. We're working for you, not the other way around.

Excellence

Every cavity sealed, every seam clean, every install done with the same care we'd give our own house.

Environmental care

Less energy wasted heating and cooling leaky houses is a win for your wallet, and for the planet your kids will inherit.

From homes across Massachusetts

What summer feels like after Patriot.

Google review

"Our kids' bedrooms were 10° hotter than the rest of the house every summer. Patriot foamed the attic and now the upstairs finally feels like the rest of the house. The Eversource bill dropped almost $200 the next billing cycle, and we already know we'll be cozy in winter too."

"Cape humidity used to soak right into the house. After they sealed the crawl space, the AC actually keeps up, the musty smell is gone, and our floors aren't ice cold anymore. Patriot was easy to talk to, fair-priced, and clean. Worth every dollar."

Dale W. Barnstable, MA
Google review

"Got three quotes. Patriot wasn't the cheapest, but they were the only crew that walked the whole house with me and showed me where the heat was coming in. Family-owned, straight answers, no pressure. House finally feels right in both seasons."

FAQ

What Mass homeowners ask us first.

Is spray foam insulation worth it?

Yes. Spray foam is one of the most effective insulation solutions available because it seals air leaks while also insulating. It improves comfort, reduces drafts, increases energy efficiency, and helps protect against moisture issues.

Can insulation help lower my energy bills?

Yes. Properly installed insulation reduces energy loss throughout the home and lets your heating and cooling systems run more efficiently. The result is lower monthly bills and more consistent indoor temperatures.

Does insulation help with moisture and drafts?

Yes. High-quality insulation, especially spray foam, seals air leaks and reduces moisture intrusion. That improves indoor comfort and helps protect framing and finishes from condensation.

Is old insulation a problem?

Older insulation often loses effectiveness over time, especially in older homes. Outdated materials may no longer provide proper thermal protection. Upgrading can significantly improve comfort, efficiency, and overall home performance.

Do you offer residential and commercial insulation services?

Yes. Patriot Spray Foam Insulation provides residential and commercial insulation services throughout Massachusetts.

What areas of Massachusetts do you service?

We serve homeowners and builders across Massachusetts from our base in Rockland, including the South Shore, Greater Boston, MetroWest, Cape Cod, Worcester County, and the North Shore. Call us to confirm availability in your town.

Our summer calendar fills up fast. Book ahead and walk into the next stretch of 90° days with a house that finally feels the way it should. The same install will keep you cozy through winter, too.
