We respect that we’re working in your home, so care, attention to detail, and clear communication are built into the way we work.

Frequently Asked Questions

We get a lot of questions from homeowners who want better comfort, less noise, and improved performance from their existing windows—without replacing them. Below are some of the most common things we’re asked about our services and approach.

Draught sealing closes gaps around windows and doors that let cold air in and warm air out. It improves comfort and can significantly reduce heating and cooling costs.

Yes—older homes in Sydney often have timber windows with gaps, making them ideal candidates. Draught sealing is a low-impact upgrade that preserves the original windows.

Vacuum sealed glass uses two panes with a vacuum gap, offering excellent insulation in a much thinner profile than traditional double glazing—perfect for heritage windows.

 In most cases, yes. It’s designed to retrofit into existing frames without replacing the entire window.

Yes, both solutions help reduce noise intrusion, with vacuum sealed glass offering a noticeable improvement for traffic and street noise.

Many Sydney homeowners see meaningful reductions in heating and cooling use, especially in winter. Actual savings depend on your home, window condition, and usage habits.

Yes. Draught sealing and vacuum sealed glass are often approved because they maintain the original look of the windows.

Draught sealing is often completed in a day, while vacuum sealed glass installations vary depending on the number of windows but are typically fast and minimally disruptive.

Generally no, especially for internal or like-for-like upgrades, but requirements can vary. Inner West Window Specialists can advise based on your property.

Absolutely. Draught sealing alone delivers immediate comfort improvements and is one of the most cost-effective upgrades you can make.
