Granby grew in successive rings: older homes near the centre, bungalows from the 1960s and 70s, then cottages and semi-detached homes toward the city limits. In the Eastern Townships, winter swings between deep cold and thaws, the worst-case scenario for an under-insulated attic, where condensation and eave ice take hold. Bringing the insulation up to R-50 protects the roof as much as the wallet. Our online quote gives the exact price for your home, with no one needing to stop by before the work.
