Problems with Old Windows

Aluminium windows and doors in older homes are now 40+ years old. Problems include:

Frequently Asked Questions

How are Windows replaced?

With old aluminium windows, the sashes and “bricked in” sub-frames are generally removed – “back to brick”. The new windows are then “angle trim fixed” similar to Commercial Shopfront windows.

Many timber windows double as structural support for brickwork above and roofs. In such instances only the sashes may be removed. We endeavor to cover all old timber frames with angle trims wherever possible.

Can the existing wall opening size be changed?

Generally this requires structural work and involves other trades such as carpenters, plasterers and bricklayers. We do not do this work however we will install a new window or door to the new prepared opening.
