How Much Does Car Soundproofing Cost in Ireland? Published Prices, and the Cheap Way That Works
Car soundproofing in Ireland costs from €80 to €200 per door at Dublin workshops that publish prices, with floors from €600 and full-car treatment from €3,060. DIY material kits sold online are cheaper if you do the work. Here is every published price we found on 9 October 2026, why per-door prices differ, and where to start on a budget.
On 9 October 2026 Radio Masters in Dublin published door soundproofing at €80, €100 or €140 per door depending on the level, €240 per wheel arch and €800 for the floor. At Radio King doors start from €200 per door, the roof and the floor from €600 each, wheel arches from €700 per pair, and packs from €1,260 for four doors and the roof. We are not the cheapest per door; the difference is in the layers and the trim work. DIY kits sold online cost less again. On a budget, treat the doors first for better speakers, and the arches and floor for road noise.
“How much does car soundproofing cost in Ireland, and is there a cheap way to do it?” Published Dublin prices on 9 October 2026 ran from €80 to €140 per door at Radio Masters, with €240 per wheel arch and €800 for the floor. At Radio King doors start from €200 per door, the roof and floor from €600 each, and packs from €1,260. We are not the cheapest per door, and we explain why below. The cheapest route of all is a DIY material kit bought online, if you do the work yourself.
Prices checked on 9 October 2026. Every figure below comes from the business’s own website on that date, with a link, and we compare like with like: area treated, layers and fitting. Prices change, so check before you book. How we compare is explained in our guide to cheap car electronics fitting.
The cheapest ways to soundproof a car in Ireland
1. A DIY material kit. Damping mats, foam and absorber kits are sold online in many sizes. We have not checked a price we can stand behind, so we do not quote one. The material is the cheap part; the work is taking the door cards and carpets out, cleaning the panels, bonding the layers and putting everything back without broken clips.
2. A workshop that prices per door. Radio Masters publishes door soundproofing at three levels: Level 1 €80, Balanced €100 and Level 2 €140 per door. Wheel arches are €240 per arch and the floor €800, with a one-year installation warranty. Four doors come to €320 to €560 depending on the level.
3. A fitting chain. We found no soundproofing service listed by Halfords Ireland, and no published price from other chains.
4. A specialist with packs. At Radio King doors start from €200 per door, the roof from €600, the floor from €600 and wheel arches from €700 per pair. Packs cover the common goals: Urban & Acoustic (four doors and the roof) from €1,260, Highway & Road Noise (doors, floor and all four arches) from €2,520, and Full Vehicle Isolation from €3,060. Per door, that is more than the lowest published price. The next section is what the difference buys.
What the cheap price usually leaves out
“Per door” is not one job. Two doors at different prices can have very different work behind the card.
- Layers. Butyl damping is the first layer: it stops the metal ringing. On its own it does little for airborne noise. A fuller treatment adds closed-cell foam to decouple and seal, and an absorber for the noise that gets past. Damping only is the quickest version; it is also why some soundproofing jobs disappoint.
- Outer skin and inner skin. A door has two metal skins. The outer one is reached through the openings in the inner one, behind the speaker. Treating the outer skin stops it drumming; sealing the openings in the inner skin turns the door into a proper box for the speaker. A cheaper door may get the first and not the second.
- The door card. The plastic card itself buzzes against the frame. Felt or foam on the card and its contact points is what stops the rattles you actually hear.
- Coverage and preparation. Material bonds to clean metal. Stuck onto dust or wax, it can peel when the weather warms up. How much of the panel is covered changes both the result and the time.
- Clips, drains and wiring. Door cards and trim are held by clips, many of them single-use. Forced back, they rattle. Door drains must stay clear or you get damp instead of quiet, and wiring looms and airbag connectors must not be buried under material.
Ask any installer, us included, which layers go on, which skins are treated and whether broken clips are replaced. Then compare the per-door prices.
Buy cheap, buy twice: the real cost
Soundproofing is the hardest job in car audio to redo. Damping material is bonded to the metal. Getting it off means heat, scraping and solvent, panel by panel, and that takes longer than putting it on. So a cheap job that has to be redone does not cost twice; it costs more than twice. With this one more than any other, pay for it once and have it done properly, rather than pay twice and end up at a specialist anyway.
| Example: four doors | Route A: cheapest | Route B: done once |
|---|---|---|
| Material | DIY kit bought online, price varies | Multi-layer material supplied |
| Labour | Your own weekend | From €200 per door |
| What goes wrong | Damping only, broken clips, rattles, drains blocked | Covered by warranty |
| Second job | Old layer stripped, doors done again from €800, plus the stripping time | Not needed |
| Total | The kit and a weekend, plus from €800, plus stripping | from €800 |
This is an example, not a promise. Plenty of DIY jobs turn out well, and a professional per-door job at a lower price can be exactly what a car needs. The cost comes when a job has to be taken off before it can be done again.
When the cheap option is perfectly fine
- One panel rattles, and a few pieces of damping behind the card will cure it.
- You want the front doors a little more solid for a speaker upgrade on an older car.
- You are patient, own trim tools and will clean every panel before anything goes on.
- A lower per-door price, as long as it covers the layers you want for your car.
Where to start on a budget
- For better sound: the front doors first. Damping and sealing the door helps any speaker, old or new. See cheap car speakers fitting in Dublin.
- For road noise and tyre hum: the wheel arches and the floor, where the noise comes in. That is what the Highway & Road Noise pack covers.
- For rain and wind drumming: the roof.
- For both: a pack. Four doors at €200 each plus a €600 roof would be €1,400 priced separately; the Urban & Acoustic pack starts from €1,260.

What you get at Radio King
We have been fitting car electronics at our Dublin workshop since 2016, on more than 32,000 cars so far. Doors from €200 per door, the roof and floor from €600 each, arches from €700 per pair, and packs from €1,260, with the exact price from your registration. We use DrArtex multi-layer material, damping and absorption together rather than a single product. Trim, door cards and carpets come out with the right tools, damaged or single-use clips are replaced, surfaces are cleaned before anything is bonded, and door drains, wiring looms and airbag connectors are kept clear. Everything goes back behind the original trim, and the work carries a one-year warranty.
Send your make, model and registration on WhatsApp and we tell you which zones make sense for your car and the exact price. The car soundproofing page shows the zones and packs.
