In Shawinigan-Sud as in the older streets downtown, a large share of homes predates 1980, often with an attic that has never been touched. Mauricie winters are unforgiving: heating bills climb fast in a house losing heat through the roof, and the reasonable cost of properties here makes the insulation investment all the more logical. A few inches of blown-in insulation change the whole winter. Get your price online in two minutes, without waiting for an estimator.
