Soundproofing FAQs

No – and any company that does is guessing. Cost depends on the noise cause, the path it travels and the area treated. Quash’s free online estimate gives you a real figure from your measurements.

Yes. Send measurements of the windows, doors, walls and ceilings you want treated to [email protected] and we price it, no obligation.

Estimates cover the full treatment as scoped. Quash has installed across Perth since 2009, with a 7-year product warranty and 6-month workmanship warranty.

Call (08) 6146 3310 – the line answers 24/7 and helps you narrow down the noise source and path before you spend anything.

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.

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.

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. We provide an accurate online estimate first, then arrange an in-home assessment to confirm the final quote.

People mix these up all the time. They’re different products built for different problems. Double glazing was designed for thermal performance. It came out of cold-climate Europe and North America, where the priority is keeping heat in and cold out. It’s a full replacement window — your existing window is gone, double glazing goes in its place. Secondary glazing (Sound-Out) was designed for noise. The system we use was developed by the New South Wales Government and Sydney Airport decades ago, drawing on European principles where people wanted to keep their existing windows rather than rip them out. It’s purpose-built for noise reduction, and it’s far more cost-effective than a full replacement. If your problem is noise, secondary glazing is the right product. If your problem is heat loss in a cold climate, double glazing is the right product. In Perth, the problem is almost always noise.

Depends on the number of windows, the sizes, and the install conditions. We don’t quote blind — we’ll give you an accurate online price after we understand the job. As a guide, secondary glazing is typically a fraction of what a full double-glazing replacement costs.

Generally no. The work is entirely on the inside of your existing window, so strata, heritage and council approvals are rarely required. Heritage bodies actually prefer secondary glazing because the original window stays visible externally.

Yes. Both panels of our SoundOut window move, so you can access your existing window for cleaning, and ventilate from either side as you like.

We try to be minimalistic and work around your existing window treatments. In most cases your blinds, plantation shutters or curtains can be reinstalled or kept in place.

Yes. Because the install is internal and can be removed cleanly if needed, secondary glazing works well in rentals where landlord approval is easier than for a full window replacement.

It’s a permanent install. The frames, glass and seals don’t degrade or lose acoustic performance over time. Got road noise, aircraft noise, or neighbours waking you up? Quash has installed over 3,000 soundproofing solutions across Perth since 2009 — and secondary glazing is the single most common thing we install. Tell us which room, what noise, what time of day, and we’ll come back to you with an honest assessment. Get a Free Quote — call (08) 6146 3310.

We significantly reduce or eliminate the noise. We customise the solution to your specific requirements and budget — typically working through the weak points in order, from the easiest wins through to addressing the wall itself, which is generally the final weak link.

Office speech privacy — making sure conversations in meeting rooms and boardrooms can’t be overheard. The noise rarely comes through one path; it leaks out through every weak point in the room. The most common ones we find are gaps above the wall (where partitions don’t fully reach the slab), poor seals around windows and doors, hollow doors with vents in them, underperforming glass, and the wall itself once everything else is sorted. We address all the weak points, not just one.

We work across offices, boardrooms, restaurants, gyms, schools, hospitals, hotels, studios, retail and strata buildings. Quash have installed over 3,000 soundproofing solutions across Perth since 2009, ranging from a single meeting room to multi-floor commercial fit-outs.

Minimising downtime is something we design for from the start. Some of our methods cost a little more upfront, but they let you stay open and only lose a day or two — instead of a week or more spent flushing plasterboard, repainting and reinstating finishes. We schedule installations to suit your business, including after-hours, weekends and staged work where needed.

Sound absorption (acoustic panels, foam, ceiling tiles) reduces echo and reverberation INSIDE a room — making the space feel quieter and more comfortable. True soundproofing reduces sound TRANSMISSION between rooms or in and out of a building, using mass and isolation. Most commercial spaces benefit from a combination of both — and getting the mix right is where experience matters.

For most commercial projects we customise the solution ourselves, drawing on our experience across thousands of installations across Perth. For very specific or technically demanding situations, we’ll bring in an acoustic engineer to model the noise problem and verify the solution. Either way, you deal with Quash from quote to completion.

Send through your floor plan, photos and a short description of the noise problem and what you’d like to achieve. We’ll come back with an online estimate first — no sales rep, no pressure. If you’d like to proceed, we can arrange a site visit. Call (08) 6146 3310 or use the quote form to start.

It depends on the space, the problem and the result you need – we don’t do blind ballparks. We assess it, calculate it properly, and send you an honest price. Often the fix is more targeted, and cheaper, than people expect.

Anywhere from half a day to a couple of weeks depending on scope. We give you a clear timeframe up front and work to it.

Yes. For offices, restaurants, gyms and retail we regularly work nights and weekends so your business keeps running.

Usually yes. We’ve got effective options that don’t involve major structural change, which keeps landlords and strata happy – and some are removable if you move on.

Where a job needs it for a building certifier, council or fit-out requirement, we can supply the product ratings and documentation to support compliance.

Yes. We guarantee we’ll get you a significant reduction in the noise. We only take a job on if we’re confident we can get you a result – and if we can’t, we’ll tell you straight up.

Yes – that’s mostly a reflection and echo problem, and acoustic panels make a big difference fast, often without changing the look of the fit-out.

Complete our online quote form or give us a call. Beforehand, it’s best to obtain rough measurements, window types and specific details on the noise issue. We will be able to provide you with an indicative cost to see whether a solution is within your budget. If you wish to proceed we will come to your home or office to measure and confirm our quote.

As our soundproofing solutions are generally installed inside, and do not alter the appearance of the building, strata approval has never been required. Having said that, it is recommended to seek it out and in some cases, request the landlord share the costs of installation.

Generally between 2 and 4 weeks depending upon the time of the year and demand at the time.

When installing windows, we can match nearly every powder coated frame in WA, let us know your colour or take a photo for us and we’ll track it down. Acoustic panels can be customised to match any decor and/or include your own branding or art work.

Naturally, most sound proofing solutions reduce thermal transfer, making it cheaper to cool your space in summer and warm it in winter.

Yes, we have installed replacement windows and acoustic panels in heritage listed buildings.

It looks like a plain, flush-panelled door — clean, paintable, designed to fit any interior or exterior aesthetic. The acoustic performance is in the core and the seals, not the face. We can also add moulding to give it more of a heritage look and character.

No. We use your existing door furniture wherever possible — handles, locks, latches. We can fit new hardware if you want to change the look, but you don’t have to. If you do want a new look, generally you buy and we fit — keeps it simple as long as the mechanism is the same.

Depends on what you’ve got now. Our doorset is rated Rw 36; a typical hollow-core internal door is around Rw 15. Replacing one with the other gives you a significant uplift — well clear of a perceived halving of the sound. If your current door is glass or aluminium the uplift is still significant; if you’re already on a heavy solid-core with good seals it’s smaller but still measurable. We can also add barrier panels to existing doors, depending on usage and aesthetics.

Depends on the size, the finish (interior/exterior), and whether we need to upgrade the frame. Once we have some details we can send you an online quote. A Quash custom doorset is significantly more than a hardware-store door — and significantly more cost-effective than continuing to live with the noise.

Four to six weeks from order, because each door is custom manufactured for your specific opening. We book the install date during that window so the changeover happens efficiently.

Yes. We supply with an exterior weather-sealed finish — common for street-facing doors on busy roads, flight-path properties, and home offices opening to a courtyard.

We strongly recommend our install. Performance depends as much on the seal install and the threshold drop-down as on the door itself. Doors supplied without our install can underperform significantly.

It’s heavier than a hollow-core door but designed to hang and swing normally on three properly-fitted hinges. People who live with them don’t comment on the weight — they comment on the silence.

Possible, but it’s a permanent install and a custom door, so it’s an investment that stays with the property. Talk to your landlord first. Got a door letting noise through? We’ll fix it properly. Quash has installed over 3,000 soundproofing solutions across Perth since 2009. Send us the door details — what room, what noise, what’s the existing door — and we’ll come and measure, listen, and recommend the right doorset. Get a Free Quote — call (08) 6146 3310.

Honest answer: most people don’t notice. When we put panels on a ceiling, no one looks up — people walk into a room and look at the features. On a wall, we generally pick a neutral colour that blends with the existing palette. Or you can go the other way — feature colours, printed graphics, suspended panels as a design element. We’ve done both extremes. Up to you.

Of all the acoustic problems we solve, reverberation is the easiest to get a great result on. As a rule, when we walk in with the panels and lean them against the wall — before we’ve even installed them — clients can hear the difference. “Wow, I can hear it already.” Once you take reverberation out of a space, it’s day and night. How do we know how many to install? We calculate it — the volume of the space, the surfaces, the use case — using the same method we’ve used for 15 years. No rough rules of thumb. Specific calculation, every job.

Depends on the number of panels and the access, but it’s not a dirty job — no demolition, no plaster dust, no major disruption. Most jobs go up over a day or two for a typical office or restaurant; larger venues or full wall coverage run longer. We aim for an aesthetically balanced layout — no random cutouts, and where panels go to full wall coverage, no junctions or gaps.

Depends on room size, ceiling height, and finish (nude white vs VertiFace overlay). We don’t quote blind — we calculate the panel area required, then price it. Smaller rooms can be very affordable; larger venues with feature finishes cost more.

You can buy them, but performance depends on the calculation and placement. Too few won’t fix the problem; too many in the wrong spots wastes money. We recommend professional install for anything beyond a single small space.

Minimal. We use methods appropriate to the surface — direct stick, mechanical fix, or suspended — and panels can usually be removed cleanly if needed.

Less than people expect. The scrim face resists dust. For most environments a light vacuum once or twice a year keeps them looking new.

Yes. Autex QuietSpace meets the required fire ratings for commercial applications. Full documentation is provided with every proposal.

Permanent install. They don’t degrade acoustically or lose performance over time. The fabric face can be replaced or refreshed if the design changes years down the track. Room too echoey, too loud, or just exhausting to be in? Quash has installed over 3,000 soundproofing solutions across Perth since 2009. We’ll come and look, listen, calculate the panel area needed, and recommend the right finish — whether that’s an invisible ceiling install or a feature wall. Get a Free Quote — call (08) 6146 3310.
