Retrofit Double Glazing
Upgrade your existing windows for superior insulation and warmth without the need for full frame replacement. Reduce condensation, noise and energy bills.
WHY RETROFIT
Warmer Homes Without the Full Replacement Cost
Why Retrofit?
Canterbury winters are no joke. If your home has single-glazed windows, you’re losing a significant amount of heat through the glass, every single day. Retrofit double glazing keeps your existing timber or aluminium frames and replaces only the glass with a sealed double-glazed unit.
This means less disruption, lower cost and the same excellent thermal performance as brand-new windows.
Benefits
- Reduce heat loss by up to 50% through your windows
- Eliminate condensation on the inside of the glass
- Reduce outside noise
- Increase your home’s value and comfort
- No resource consent needed for like-for-like upgrades
- Keep your existing window frames intact
How It Works
We remove your existing single pane and replace it with a sealed double-glazed unit (DGU) that fits your existing frame. The result: a warmer, quieter, drier home without the cost or hassle of replacing the entire window.

Before & After
Your existing joinery stays exactly where it is - we take out the single pane and fit a sealed double glazed unit into the same frame. Drag the slider on any job below to see the change.
In aluminium retrofit, fixed panels are re-beaded and opening sashes are replaced to fit double glazing. The window looks and operates exactly as before while delivering improved thermal performance.

Although it takes skill, precision and time, timber retrofit is straightforward. The old glass comes out and a deeper rebate is routed into the timber so the thicker double glazed unit can be fitted. The glass is then held in place by a primed cedar bead, ready for your painter to finish in your exterior colour.
