Replacement Double Glazed Units & Glass Repairs Christchurch

Misted, blown or damaged double glazing? We can replace it.

Have you noticed condensation between the panes of your double glazing? Perhaps your windows have become cloudy, misty or difficult to see through. This is often a sign that the sealed double-glazed unit has failed.

The good news is that you don’t necessarily need to replace your entire windows.

At Winstone Glass, we specialise in replacing existing double-glazed units, allowing you to restore the clarity and performance of your windows while keeping your existing frames and joinery.

Whether you have aluminium, timber or steel windows, we can help with replacement double-glazed units to suit your home.

Replacement Double Glazed Units

Double glazing is made up of two panes of glass separated by a sealed insulating space. Over time, the seal around the unit can deteriorate, allowing moisture to enter between the panes.

This can cause:

Condensation or moisture trapped between the glass.
Cloudy or misty windows that can’t be cleaned.
Reduced visibility through the glass.
Deterioration in the thermal performance of the unit.

If your double glazing has blown or failed, replacing the glass unit is often a practical and cost-effective alternative to replacing the entire window.

Upgrade Your Existing Double Glazing

Replacing your double-glazed units is also an opportunity to improve the performance of your existing windows.

Depending on your joinery and requirements, we can discuss options including:

Standard double glazing: Replace your existing units with new double glazing.
Argon gas: An insulating gas between the panes that helps improve thermal performance.
Low-E glass: Specially coated glass designed to reduce heat transfer and help keep your home warmer in winter.
Enhanced thermal performance: Options such as Solux-E and Solux-Ultra to help improve your home’s year-round comfort.

We’ll help you choose the right glass specification for your home and budget.

We can replace broken or failed double-glazed units with glass matched to your existing windows. Because we work with a wide range of glass suppliers, we have access to an extensive selection of glass types, thicknesses, tints and specifications, allowing us to find the closest possible match to your existing units. Whether your glass is misty, blown, cracked or broken, we can help find the right replacement solution.

One of the biggest advantages of replacing your double-glazed units is that you can keep your existing window frames and joinery.

We work with a range of existing window types, including:

Timber windows.
Steel windows.

Rather than undertaking the expense and disruption of replacing your entire windows, we remove the old glass units and install new double glazing into your existing frames, where suitable.
