Struggling to keep your home warm during Christchurch winters?
Retrofit double glazing allows you to keep your existing frames while upgrading to modern double-glazed units.
It’s a smart, cost-effective way to improve comfort without a major renovation. You get better insulation, less condensation and improved comfort, without the disruption and expense of replacing all your windows.
Retrofit double glazing is a method of upgrading your existing windows by replacing single panes of glass with sealed double-glazed units, while keeping your original frames where suitable. It is often ideal for timber or aluminium framed windows.
If you’re unsure whether retrofit or full replacement is the better option, our team can assess your windows and provide honest advice.
