Residential Soundproofing Perth

We have completed more than 3,000 soundproofing jobs across WA since 2009, and a big share of them are homes. Most people call us for the same reason: they can't sleep, can't work from home or can't switch off because of noise they didn't choose. Here is what we help with most:
  • Road and freeway traffic noise
  • Aircraft noise under the Perth Airport flight path
  • Neighbours heard through shared walls in apartments, villas and townhouses
  • Footsteps and voices through the floor of two-storey homes
  • Air conditioners, pool pumps and bore pumps
  • Echo in open-plan living areas, stairwells, home theatres and music rooms

Plug the holes first

Sound takes the easiest way in. In most Perth homes that is the windows and doors, not the walls. So before we talk about products, we come out, listen to the noise and find the weak spots. Then we fix those first.

It is usually the most cost-effective way to get a real result, and it means you are not paying for work that won’t make a difference. Once the main paths are sorted, you will often start to notice the next weakest spot. That is normal, and we will tell you up front where it is likely to be.

What we install in homes

Secondary glazing for windows

Our SoundOut secondary windows fit inside your existing frames, so you keep your windows and the outside of the house doesn’t change. Every window uses 6.5 mm VLam Hush acoustic glass with the maximum air gap we can achieve for your windows. SoundOut was designed for noise, where standard double glazing was designed to keep heat in or out. If your current windows are in really poor condition, we will tell you and suggest replacing them instead. More on window soundproofing.

Acoustic doors and seals

A hollow-core door with gaps around it lets almost everything through. We fit acoustic doors starting from an Rw 31 rating, with perimeter and drop seals, to bedrooms, studies, home theatres and balconies.

Walls, ceilings and floors

For neighbour noise through a shared wall, we install an acoustic wall lining system on the common wall. For noise between floors, we build an acoustic system into the ceiling below. Both are finished to match the rest of the room.

Acoustic panels for echo

Hard floors, high ceilings and open-plan living make homes echo. Autex QuietSpace panels soak that up. They are made to measure, come in a range of colours and can be custom printed with artwork or photos.

Air conditioner and pump enclosures

Noisy outdoor units are a common cause of neighbour complaints. We design and build acoustic enclosures that quieten the unit while letting it breathe.

Real jobs, real Perth homes

  • Under the Perth Airport flight path: a shift worker couldn’t sleep during the day. We worked on the balcony door and the window beside his bed, including a lead-lined Rw 39 acoustic door.
  • Adelaide Terrace apartment: secondary sliding windows with 6.5 mm acoustic glass in the living area and nursery, finished before the new baby arrived.
  • Fremantle two-storey home: an acoustic ceiling system built between the exposed joists to stop noise coming through the floor.
  • Apartment shared wall: an acoustic wall lining on the common wall so the neighbours’ noise stays on their side.
  • Strata apartment: retrofit secondary glazing behind the existing windows, so nothing changed outside the building.
  • Swanbourne family home: 25 mm Autex QuietSpace panels through the home and acoustic panels in the stairwell to take out the echo.

Residential Soundproofing FAQs

Common questions from Perth homeowners about soundproofing.

Yes. Quash reduces traffic and aircraft noise through secondary glazing, wall treatments, and ceiling work. Total elimination isn't realistic, but most clients go from "constantly aware" of the noise to "barely notice it."
Yes — most solutions don't alter building structure or external appearance, so they typically pass strata approval. Internal acoustic panels, secondary glazing, and floor treatments are usually fine. Quash advises on what's likely approved before you proceed.
Most residential jobs finish in one to three days. A single window retrofit takes a few hours; a bedroom or media room treatment is one to two days. Quash provides a clear timeline with every quote.
No. Quash works room by room, leaves the space tidy each day, and keeps dust and noise to a minimum. Most homeowners stay in the property throughout the installation.
Soundproofing stops sound moving between spaces — like blocking road noise from a bedroom. Acoustic treatment improves sound quality inside a room — like reducing echo in a home theatre. Most projects combine both.
Yes — neighbour noise is one of the most common reasons people call Quash. Solutions depend on whether sound travels through walls, ceilings, or windows. Voice and TV noise can usually be reduced significantly; loud bass is harder to eliminate fully.
Yes. Quash provides obligation-free quotes for residential projects across Perth. To keep our prices competitive, we don't have full-time sales reps on the road — instead, you provide some details about your space and noise issue, and we give you an accurate online estimate first. If you want to proceed, we then arrange an in-home assessment to confirm the final quote.
