Attic insulation

Blown-in fibreglass to today's R-60, with air sealing and ventilation baffles. Most attics are done in a day, from the hatch, without opening a wall. Slide to compare.

Before: old, uneven batts in an attic, with red ventilation baffles freshly installed at the eaves. After: a deep, level layer of blown-in fibreglass across the attic floor.
BeforeAfter

Left: settled batts at about R-15, baffles just installed. Right: blown-in fibreglass to R-60, level from eave to eave, every rafter bay still ventilated.

Nano roof treatment

Asphalt shingles dry out, curl and shed granules. Our nano-polymer sealer soaks into the shingle, locks the granules and makes the roof shed water again. A fraction of the cost of replacing, with a 10-year written warranty.

Why homeowners pick TrueNorth

R-60, measured

We blow to the marked depth and measure it at the end. The R-value goes on your invoice.

Baffles and air sealing

Every rafter bay vented, every gap sealed. That is what stops ice dams, summer heat and mould.

Wet or contaminated insulation is vacuumed out and the wood treated before anything new goes in.

Mould in the attic

It is almost never a roof leak. Warm, humid air from the house rises through gaps around pot lights and the hatch, hits the cold roof deck and condenses. Block the soffits with insulation and it never dries. We stop the moisture, treat the wood, then insulate.

STAGE 1Light fuzz near the eaves. Air seal, vent, treat the surface.
STAGE 2Dark stains spreading down the rafters. Treat all surfaces, replace wet insulation.
STAGE 3Black growth across the deck, insulation contaminated. Full removal, treatment, ventilation, new R-60.
