House Extensions

Thanks to the premium double glazing installed into our house extensions, you can enjoy a warm space all year round.

Enhanced Thermally Efficient

With the cost of living on the rise, it is important that any double glazing installed into your Harrow home is thermally efficient. The modern double glazing traps a pocket of warm air between the panes, helping your space stay consistently comfortable.

Our double glazing will minimise heat loss and will keep draughts from gaining entry to your property. These windows and doors will also feature weatherproof seals in place, keeping wind, rain and snow outside.

As your space will stay naturally warm in winter, you may find yourself relying less on your central heating. This could lead to minimised energy bills and a more improved carbon footprint.

Secure Your Home

Underperforming single or double glazing could lead to expensive and long lasting water damage. Our double glazing will stop rain from causing damp and mould causing negative effects on your property and your health.

The glass is internally beaded for your peace of mind. This means that even the most determined intruder won’t be able to force their way into your property. Our windows and doors are crafted using premium materials and high quality locking systems.
