Soundproofing FAQs
We’ve answered the most common ones below.
General Questions
What does Zeus Soundproofing do?
We specialise in reducing unwanted noise and improving thermal performance in homes, offices, schools, studios, and commercial buildings. Our services include the installation of acoustic window systems, soundproof doors, insulation upgrades, acoustic wall and ceiling panels, and more.
Do you only work in Western Sydney?
No — we service all of Sydney, the Lower Blue Mountains, Blue Mountains, Northern Beaches, Central Coast, Wollongong, and surrounding areas.
Are your solutions suitable for both new builds and existing properties?
Yes, absolutely. We work with builders, renovators, homeowners, and business owners. Our systems can be retrofitted to existing buildings or integrated into new constructions.
Installation & Materials
Will I need council approval for soundproofing?
In most cases, no. Internal upgrades and window replacements generally do not require council approval. However, if you’re in a heritage zone or strata-managed property, we recommend
checking first.
How long does installation take?
It depends on the scope. A single window may take a few hours; a full home fit-out might take several days. We’ll give you a schedule upfront and keep you informed throughout.
Do you use Australian-made products?
Yes — wherever possible. We use local suppliers for custom-made window frames, acoustic glass, insulation, and sealants. All installations are completed by our trained in-house team.
Acoustic Performance
How much noise can you reduce?
Results vary depending on the type of construction and existing noise levels, but reductions of up to 70–80% are common with the right solution. We will recommend what’s best for your space based on a site inspection.
Can you block low-frequency noise like trucks or aircraft?
Yes, we specialise in treating low-frequency noise using combinations of dense materials, secondary glazing, and acoustic framing systems. These techniques are ideal for homes under flight paths or near busy roads.
Will it make my home feel warmer or cooler?
Yes — many of our acoustic upgrades also improve thermal insulation, reducing heat loss in winter and heat gain in summer. This helps cut energy costs and reduces condensation.
Pricing & Process
How much does it cost?
Every quote is customised based on your building, noise levels, and access. Visit our Pricing & Quoting page for ballpark ranges, or request a free quote for an accurate assessment.
Can I get a quote without a site visit?
We can offer a rough estimate based on photos or plans, but a site inspection is always required before finalising a quote. This ensures your solution is tailored correctly.
Do you offer warranties?
Yes. All installations include workmanship warranties, and most materials come with manufacturers’ warranties. We’re a licensed builder, so your investment is protected.
