Sound deadening for cars in Canada: what it costs and what to buy

Updated 4 November 2026

Car sound deadening in Canada costs about CA$18 to CA$22 for a small pad or a 3.7 sq ft pack, about CA$25 to CA$41 for an 8.7 sq ft mat, and about CA$74 to CA$98 for a 25–36 sq ft kit. Bulk kits cost from about CA$355 to CA$770. For current prices, send a request on BlaBlaPrice, where the AI looks through sellers' websites and price lists in Canada and shows what it finds.

Local rules and warranty

A widely shared discussion says that properly installed car soundproofing does not void the vehicle warranty, but your own warranty terms are the final word, so read them before fitting anything. Canadian sound-insulation standards are written for buildings, where a minimum STC rating of 50 is required in laboratory tests, so check a car product's own specification instead of a building rating.

Season: plan the fitting before winter

Winter in Canada runs from December to February, and a cold garage makes fitting slower and less pleasant, so November is a sensible time to plan the job. From June to August the car is easier to work on in a warm garage, which suits a longer session with the panels off.

Sizes and how it is sold

Canadian listings mix square feet with millimetres, and thickness is given in mil, such as 50, 80 or 197 mil. Work out the area you need before comparing prices. Products are priced in Canadian dollars, and the bulk kits cost many times more than a single pad. Ask each seller about delivery to Toronto, Montreal, Vancouver, Calgary or Ottawa before you order.

What to write in the request

Say which parts you want to soundproof, such as doors, floor or roof, along with the car model and year. Tell the seller whether you want a DIY kit or fitting, the area you need, the city and your budget.
