Our draught seals were developed through years of upgrades to timber windows in the cold climates of England, Scotland and Ireland.
They stop up to 86% of airflow and up to 10 dB of noise.



Our glass has been selected to suit the unique Australian climate and can actually achieve the same performance as triple-glazing if necessary in your area.
We’re very excited to offer Glavenir Vacuum Insulated Double Glazing which is a brand-new technology by Panasonic.
Glavenir is proven to perform better than standard triple-glazing units, which can help you achieve huge improvements in comfort and energy efficiency.
Using traditional craftsmanship and modern materials, we’ll restore your windows and make better than new.
This includes the installation of our weather-tight draught seals and ultra-high performance double glazing.
Whilst this can be a premium option, you will dramatically increase the functionality and energy efficiency of your windows.
By maintaining the character of your property with these modern updates, you can significantly increase your property value whilst keeping ongoing running costs down.
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.
Please provide us with some details about your timber windows and we’ll get back to you shortly.
