Do these problems sound familiar?
Loud Road & Tyre Noise
Soundproofing the floor and wheel arches makes it easier to enjoy music and conversations at highway speeds.
Wind Noise
Insulating the doors helps soften wind noise, making sudden gusts less intrusive inside the cabin.
Interior Rattles
Treating panels and trim contact points helps stop annoying vibrations and buzzing on uneven roads.
Exhaust & Cabin Drone
Highway driving becomes tiring from constant tyre roar, booming and road noise.
Which Parts of Your Car We Soundproof
Different noises enter the cabin through different parts of the car. We identify where the unwanted noise is coming from, then target the areas that will make the biggest difference.

Why customers choose us
Careful Interior Removal
Sound deadening requires careful access to doors, floors, roof panels and trim areas. We remove and refit interior parts with attention to detail.
Before and After Testing
Where possible, we check cabin noise before and after the installation so the improvement can be measured.
Sydney-Based Workshop
Our workshop is located in North Manly and serves drivers across Sydney, including the Northern Beaches, North Shore and surrounding areas.
Specialist Sound Deadening Workshop
We focus on automotive sound deadening and cabin noise reduction, not general car repairs.
Premium Automotive Materials
We use quality sound deadening, insulation and anti-rattle materials selected for each area of the vehicle.
