Brossard has entire streets of split-levels, cottages and bungalows built between the 1960s and 1990s, well before today's insulation requirements. In these homes, the temperature gap between the main floor and upstairs almost always points to a tired attic. Bringing the insulation up to R-50 evens out comfort and lowers the electricity bill, with no invasive work. Because these house models are so well known, our online calculator gives an exact price from your address, no salesperson to let in.
