Car Boot Soundproofing
Reduce tyre roar, rear-panel vibration, exhaust-related resonance and road noise entering through the back of the vehicle with targeted boot sound deadening.
Our boot treatment covers the main rear noise paths: the tailgate, rear floor including the spare-wheel well, and the rear wheel arches from inside the vehicle.
How the service works
How we soundproof a car boot
The rear of a vehicle contains several thin metal panels close to the tyres and road surface. Treating these areas together helps reduce resonance and noise entering the cabin from behind.
01 / ACCESS & PREPARATION
Remove rear trim and prepare the panels
We remove the boot floor, side trims and the trim required to access the tailgate and inner rear wheel arches. The metal is cleaned and prepared before any sound deadening layers are installed.
02 / REAR FLOOR & SPARE-WHEEL WELL
Treat the rear floor and spare-wheel niche
Vibration-damping material is applied to the rear floor and spare-wheel well to control large metal surfaces that can resonate from tyres, suspension, exhaust and road impact.
03 / WHEEL ARCHES & TAILGATE
Soundproof the inner rear arches and tailgate
The rear wheel arches are treated from inside the cabin because they sit close to the tyres and are a major path for road and tyre noise. The tailgate is also damped to reduce panel vibration and rattles before all trim is refitted.

Why treat the boot?
Benefits of car boot sound deadening
01
Less rear tyre roar
Inner rear wheel arch treatment helps reduce noise generated by tyres, coarse road surfaces and water spray.
02
Reduced floor resonance
Damping the rear floor and spare-wheel well helps control thin sheet metal that can amplify vibration and low-frequency road noise.
03
Quieter tailgate
Sound deadening can make the rear door feel more solid and help reduce vibration, rattles and panel resonance from the back of the vehicle.
04
Calmer cabin on highways
Reducing noise from the rear of the car can make longer drives more comfortable, especially in hatchbacks, wagons and SUVs.
05
Better bass control
For vehicles with a subwoofer or upgraded audio system, a more controlled boot structure can reduce unwanted panel vibration and rattling.
06
Targeted treatment
The service focuses on the areas that matter most rather than adding material without purpose, helping balance noise reduction, fitment and weight.
Included areas: rear tailgate, rear floor/spare-wheel well, and rear wheel arches treated from the inside of the vehicle.

Frequently asked questions
What areas are included in boot soundproofing?
Our boot treatment includes the rear tailgate, the rear floor including the spare-wheel well, and the rear wheel arches treated from inside the vehicle.
What type of noise can it reduce?
Boot sound deadening is mainly aimed at tyre roar, road noise, rear-panel resonance, vibration and rattles. The result depends on the vehicle body, tyres, exhaust, factory insulation and the rest of the cabin.
Why are the rear wheel arches important?
The arches sit directly beside the rear tyres, so they can transfer tyre and road noise into the cabin. Treating them from the inside helps control both panel vibration and airborne noise.
Do you soundproof the spare-wheel well?
Yes. The spare-wheel niche is part of the rear floor treatment and is a useful area to damp because its curved metal structure can transmit and amplify vibration.
Is boot soundproofing useful for car audio?
It can be particularly useful when a subwoofer is installed in the boot. A more controlled rear structure can help reduce unwanted rattles and panel resonance.
Can the boot be treated separately?
Yes. Boot soundproofing can be completed as a standalone service or combined with doors, floor, roof or a full-car sound deadening package.
Talk to us about your car
Tell us the make, model and year, and describe where the noise is coming from. We can advise whether boot soundproofing alone or a broader treatment is the better option.
