Airtight, weather-resistant seal
Foam expands into cracks and gaps where batts are ineffective, stopping household air infiltration and drafts at the source.
Serving New England for over 30 years
Seal it once. Save every season.
Spray foam insulation expands to fill the cracks and gaps that fiberglass and cellulose leave open, forming an airtight, weather-resistant bond that cuts heating and cooling costs for good.

Benefits
Insulation that also stops the air.
Standard insulation slows heat. Spray foam slows heat and seals the leaks that let it escape in the first place.
Lower heating and cooling bills
Outperforms fiberglass by air-sealing the home, boosting the efficiency of your furnace and air conditioner and cutting utility costs.
Greener home, smaller footprint
Less energy burned for the same comfort. Our open-cell foam is water-blown and vegetable-based, with no ozone-depleting chemicals.
50–70%
of the energy consumed in an average home goes to heating and cooling. Inadequate insulation and air leakage are the primary causes of that energy being wasted.
Spray foam vs. the rest
Why we spray foam:
Fiberglass, cellulose, and rock wool slow heat down. Spray foam slows heat down and seals the leaks that let it out. Here's how they stack up.

R-value measures resistance to heat flow per inch of thickness. Higher is warmer. We install both open-cell and closed-cell spray foam and will recommend the right one for your building in the on-site assessment.

Testimonials
What our customers say.
Homeowners across New England on the crew, the process, and the difference they felt afterward.
We've already noticed a 5-degree difference on the third floor since Pro-Spray did our insulation. The heat retention is so much better that we've actually turned the heat down on the first and second floors. The whole house feels warmer and our bills should show it too. Thanks guys!
Everything looks good, your guys did a great job with everything. The inspector was impressed too, which says a lot.
Really appreciated how flexible you guys were and how fast the turnaround was. The process was easy, with no headaches. The work came out great, and we can already feel the difference.
The crew showed up on time, pulled out the old insulation, sealed off the work area, then got to spraying. Worked hard the whole time and cleaned up when they were done. Room's completely draft-free now. Great job all around.
Job looks excellent. What stood out to us was how fast and clean the spraying was. I could tell they knew what they were doing and really appreciate the care they put into it.
Friendly, professional, quick - exactly what you want. If any of our friends need insulation work done, we're sending them your way.
