Absolutely — and this is not optional. Installing insulation over an existing moisture or water entry problem will trap moisture inside the wall assembly, leading to mold growth, wood rot, and structural damage. A reputable contractor will always conduct a thorough moisture inspection and ensure any water entry issues are fully resolved before proceeding with insulation installation. At Mas Air Home Comfort, moisture assessment is part of our standard process.

A typical residential basement insulation project in the GTA takes one to two days depending on the size of the space, the type of insulation, and the complexity of the layout. Spray foam projects may be completed faster since the product expands quickly and eliminates the need for a separate vapour barrier installation. Our team will provide you with an accurate timeline during your free assessment.

Yes. Basement insulation — particularly mineral wool (Rockwool) batts and open-cell spray foam — provides meaningful soundproofing benefits, reducing the transmission of impact noise and airborne sound between your basement and main floor. This is especially beneficial if your basement is used as a rental unit, home office, or entertainment space.

It depends on the insulation type. With batt insulation (fiberglass or mineral wool), a polyethylene vapour barrier must be installed on the warm side (interior facing) of the insulation, properly caulked and taped. With closed-cell spray foam, the foam itself functions as an integrated vapour barrier, so no separate poly sheeting is required. Our technicians will specify the correct approach for your project during the assessment.
