Red Seal CertifiedWhat Insulation Services Do We Offer in Nanaimo?
Greenfoot provides spray foam, blown-in, batt, and soundproofing insulation for Nanaimo 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 Nanaimo Homes Need Better Insulation?
Nanaimo's cold winters and humid summers create unique insulation challenges, and upgrading can reduce heating costs by 30 to 50% while preventing moisture damage.
Mid-Island weather combines mild temperatures with frequent winter rain, while hillside neighbourhoods receive differing wind and sun exposure. A continuous thermal envelope helps reduce cold rooms and condensation across split-level floor plans.
Nanaimo's Insulation Challenges
Original insulation in mid-century and late-twentieth-century houses may be settled, compressed, or incomplete
Hillside lots create exposed upper walls and partially below-grade rooms with distinct insulation needs
Complex split-level rooflines leave short attic sections that are difficult to reach
Busy corridors and growing neighbourhood density introduce traffic and household noise
How Greenfoot Insulation Helps
Targeted spray foam closes awkward transitions between foundations, additions, and upper floors
A blown-in attic top-up restores coverage where older loose-fill insulation has settled
Mineral-wool nattes provide thermal and fire-resistant upgrades during open-wall renovations
Soundproofing makes suites, home offices, and bedrooms quieter in Nanaimo's busier districts

"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 young chaps, Marlon Marcuflo and Sylvia Richard, were wonderful to deal with. They were extremely polite, very tidy and efficient in their work, were right on schedule and did an excellent job. When they left the house there was no mess to clean up. I would recommend Greenfoot Energy Solutions to anyone thinking of upgrading their home.

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.
