Melbourne Double Glazing FAQ's

We repair timber windows as a part of the installation of draught seals and new glass, we often call this an overhaul. Typically we do not build new windows or undertake major repairs to timber rot or damage – we can refer you to a specialist service for this if needed.

We only work with timber or wooden windows.

This includes double-hung sash windows, casement windows, awning windows, fanlights, pivot windows, horizontal Yorkshire sliders and fixed windows.

Yes, we can install the high-performance double glazing into your timber windows.  We offer three different types of glass, which have been selected to suit the different climates throughout Australia, which can actually achieve the same performance as a triple-glazed window if necessary in your area.

Over time, many old timber windows are rattly, draughty and stuck.  This can lead to an influx of outside air, noise and dust which makes them terribly energy inefficient.  Our high-performance draught seals protect you from the outside air, noise and dust.  As part of the process of installing draught seals, we’ll also make your windows slide open and closed with a light touch and silky smooth.

Whilst it might be cheaper to rip out your timber windows and replace them with new plastic or aluminium double-glazing units. You will instantly lose the character of your property and it will never look the same.  Keeping original wooden windows maintains and arguably increases the value of your property.

Replacement window frames can cause problems with other parts of the window opening. And they simply won’t look right.

Your old timber windows are made of old-growth timber, that has stood the test of time in most cases.  And with a little TLC and some new upgrades, they can outperform a new window & the frame could last another 100 years.

Andrew and the team, were quick, polite and thorough in replacing the glazing of sash windows in my early Victorian cottage in St.Kilda. The windows side better than ever and the Glavenir glazing product has specs equivalent to triple glazing I understand. Can't wait to experience a toasty winter with less energy usage. The house was left mess free.

I’ve recently used Sealasash to restore my home’s original timber windows (circa 1940s) and install draught seals. Andrew worked on my house solo and did an absolutely tremendous job. All windows are back to being fully functional and I’ve already observed a drastic improvement thanks to the work undertaken. No cold morning air makes its way through the gaps in the windows meaning the house heats up far quicker, and I’m finding it also holds a steady temperature better than it ever has. Highly recommend using Sealasash to restore your windows.

We were delighted with the quality of the window repairs and the way the team conducted the work. They were efficient, reliable, clean and respectful of the communal property in our apartment complex. We've noticed huge acoustic and weather sealing improvement already—definitely recommended!

We're very happy with the job that was done! The windows feel great and I'm sure will look perfect one I finish painting them. While it's hard to measure, the house did seem noticeably quieter that night and the windows feel secure and open/close perfectly.

The Sealasash team did a great job restoring some old windows in our Federation era house. They rebuilt an old broken sash window with new wood, rope, parts, proper seals and high quality sound and heat insulating glass, all while keeping the heritage and feel completely intact. Professional and polite from the quoting, to the work, to the cleanup at the end.

So so worth it. Percy and team were extremely helpful and very responsive. Our windows from 1890 are basically brand new double glazing in Melbourne.

The Sealasash team are one of the most professional groups I've come across. Responsive, efficient and just a delight to deal with. We had a number of our sash windows and front door resealed and the difference this has made, in terms of draughts and noise from a nearby main road, is incredible. Would highly recommend them.
