What GTA Homeowners & Builders Say
"Northstar spray-foamed our basement and rim joists. The cold spots are gone and our gas bill dropped 35%. Crew was on time and spotless."
"Hired them for fireproofing on a 6-storey build. Hit every inspection and stayed ahead of schedule. We've already booked them for the next project."
"Removed nasty old attic insulation full of rodent damage and topped us up to R-60 in one day. Highly recommend."
"Got three quotes — Northstar wasn't the cheapest but the most professional by a mile. Quality of work was excellent."
