Perth’s “best-kept secret”

San Remo Learn More

After building their dream holiday home in San Remo, the home went virtually unchanged for the last 30-odd years, and as the balcony was so exposed to the coastal elements, it began to show its age and cause problems for homeowners.

In May 2023, the homeowners decided to engage with WA Custom Glass, to breathe new life into the upstairs facade.

The homeowner told us; “I’m 76 years old in a few months, and with all the years I’ve been in business I don’t think I’ve ever come across a more professional organisation. They were punctual, professional, and did a magnificent job.”

Common questions about our window replacement service

What types of windows can you replace in Perth?

How do I know if I need window replacements?

Signs include drafts, rising energy bills, condensation between panes, mould, or visible damage. If you’re unsure, our window replacement specialists can assess your current windows and offer our honest recommendations on whether you need a window replacement service.

Are your replacement windows energy-efficient?

Yes! We offer high-performance glass options like Low-E, double-glazed, and laminated glass to improve insulation, reduce UV, and increase year-round comfort.

What’s the difference between single and double glazing

We offer both single and double-glazed window options, and the right choice depends on your home, location, and goals.

  • Single Glazing: A single pane of glass. It’s a great choice for interior windows, heritage homes, or budget-conscious renovations where thermal performance isn’t a priority.

 

  • Double Glazing: Two panes of glass with a sealed gap of argon gas between them. This design improves energy efficiency, noise reduction, and indoor comfort—making it ideal for external windows and homes exposed to traffic noise or temperature extremes.
