Insulation Services in Thunder Bay, Ontario
Trusted Insulation & Rebate Experts in Thunder Bay
Thunder Bay’s homes are largely older wood-frame houses built for a rugged northern climate — but many of them predate modern insulation standards and quietly bleed heat through under-insulated attics and leaky rim joists. From Port Arthur and Current River to Westfort and Fort William, our certified team brings these homes up to today’s R-60 attic standard so you hold onto the heat you’re paying for, winter after winter.
Deep in Northwestern Ontario’s boreal region, Thunder Bay faces long, brutally cold winters with heavy snow — which means insulation upgrades deliver some of the fastest paybacks anywhere in the province. PolarCore helps Thunder Bay homeowners qualify for up to $2,350 in government rebates, with $0 upfront for most homes, and we handle every piece of the rebate paperwork from assessment to approval.
