FAQ

Frequently Asked Questions

It can be quite a big decision to upgrade your old wooden window.

That’s because it can be a major investment and requires careful consideration when taking into account other renovations or energy efficiency improvements.

To help with your research and decision making process, we’ve compiled some of our most frequently asked questions.

Our FAQs should help you come up to speed quickly, to learn all about wooden window repairs and save time, by answering many of your immediate questions.

Do you repair timber & wooden windows?

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 (in the short term) 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.
