Sound deadening for cars in Australia: prices and what to check

Updated 4 November 2026

Car sound deadening in Australia costs from about A$11 for budget foam to about A$259 for premium tile packs, and a full-car kit of around 1.8 m² is about A$105. These are approximate prices from sellers' websites in November 2026. For a quote for your car and the areas you want covered, send a request on BlaBlaPrice.

Local rules and what to check

The ACCC describes a warranty as an extra promise a business makes about a product's quality or about how it will fix problems, so read the warranty wording rather than trusting the product name. Some sellers state that they may decline a refund if the product matches its original description, so check the returns terms before you order. Do not confuse this with building noise rules: the national handbook on sound transmission in buildings covers homes and apartments, not vehicles.

Season: fit it in the right weather

Summer runs from December to February and winter from June to August. Adhesive mats stick best in warmth, so fit them in a heated garage in June to August, because cold makes them harder to press down. In December to February, the heat is the reason many buyers add a heat shield at the same time, and several products are sold as sound and heat insulation together.

Delivery and how it is bought here

Prices are quoted per product, per sheet, per roll or per kit, and sizes are given in square metres (m²). Work out the area for the doors, floor, roof and boot before you order, and ask the seller for the coverage of each kit. Several listings offer Afterpay, ZipPay and click and collect, and shipping across Australia is common, so check the postage cost against the price.

What to write in your request

Tell us the car's make, model and year, the areas you want treated (doors, floor, roof, boot), whether you will fit it yourself or want a fitter, the area in square metres, your city and your budget. A fitter in Sydney quotes differently from a parts order shipped to Perth, so the city matters.

Describe the car and the areas in your own words in the BlaBlaPrice chat, and add a photo of the car or the parts if you have them. BlaBlaPrice looks through sellers' websites and price lists in Australia and shows the prices and businesses it finds. Sellers registered on BlaBlaPrice reply with their own offer, price and delivery terms. Your contacts stay hidden, and you decide who to contact. It is free for buyers.
