Red Seal CertifiedWhat Insulation Services Do We Offer in Saint John?
Greenfoot provides spray foam, blown-in, batt, and soundproofing insulation for Saint John homes, covering attics, walls, basements, and crawl spaces.
Our team of experts offers a wide range of insulation services to meet your specific needs — from thermal performance to acoustic comfort.
Spray Foam Insulation
R-6 to R-7 per inch (closed-cell)
Closed-cell and open-cell spray foam provides superior air sealing and the highest R-value per inch. Creates a seamless vapor barrier that eliminates drafts and moisture intrusion.
Best for: Basements, crawl spaces, rim joists, exterior walls, and areas requiring air sealing and moisture barrier
Blown-In Insulation
R-3.2 to R-3.8 per inch
Loose-fill cellulose or fiberglass blown into attics, walls, and enclosed cavities. Fills irregular spaces and gaps that batt insulation misses, providing excellent coverage.
Best for: Attics, enclosed wall cavities, hard-to-reach spaces, and topping up existing insulation
Batt & Poly Insulation
R-3.1 to R-4.2 per inch
Traditional fiberglass or mineral wool batts with poly vapor barrier. Cost-effective for new construction and accessible renovation projects with standard stud spacing.
Best for: New construction walls, accessible attics, floor assemblies, and renovation projects with open stud bays
Soundproofing Insulation
STC 45-65 rating
Specialized acoustic insulation to reduce noise transmission between rooms, floors, and from exterior sources. Mineral wool and resilient channel systems for maximum sound control.
Best for: Shared walls, home offices, media rooms, bedrooms above living spaces, and exterior noise reduction
Why Do Saint John Homes Need Better Insulation?
Saint John's cold winters and humid summers create unique insulation challenges, and upgrading can reduce heating costs by 30 to 50% while preventing moisture damage.
Saint John's position on the Bay of Fundy creates a uniquely challenging climate for homes. Extreme tides, persistent fog, and maritime cold demand insulation that handles both thermal and moisture performance. From Uptown heritage buildings to East Side developments, every home benefits from proper insulation.
Saint John's Insulation Challenges
Bay of Fundy fog and tidal moisture create extreme humidity conditions year-round
Uptown Victorian and Edwardian homes have minimal insulation and significant air infiltration
Salt air from the port accelerates deterioration of traditional insulation materials
Port and industrial noise in the South End and Lower West Side requires soundproofing
How Greenfoot Insulation Helps
Closed-cell spray foam provides the moisture barrier that Fundy exposure demands for basements
Blown-in attic insulation achieves R-60 in Victorian-era homes without disturbing plaster ceilings
Batt insulation brings Kennebecasis Valley homes up to modern energy efficiency standards
Soundproofing reduces port, rail, and industrial noise for South End and West Side residents
Winter Temperature

"FIXED A LONG STANDING ISSUE I HAD FROM POOR INSTALLATION BY ANOTHER COMPANY!"
The two technicians Tanner and Halim were excellent, did a great job, very tidy, and identified 2 problems with my heat pump head, and fixed a long standing issue I had from poor installation by another company! Thank you very much, looking forward to using Greenfoot again.

"I ONLY WISH THEY INSTALLED OUR HEAT PUMP ORIGINALLY"
Great company to deal with. We hired them to move an existing heat pump after the original installer refused to help us. The estimator and the installer were both very polite, careful and thorough. I only wish they installed our heat pump originally. I would hire them again without hesitation.

The Greenfoot Team did amazing work in our home. Our old house (built in 1959) feels like a brand new construction thanks to the ductless heat pumps, spray foam insulation and HVAC installed by the friendliest staff! Everyone we spoke to from Greenfoot was helpful and just seemed genuinely happy in their job.
