Warm, light-filled comfortable living

Modern living room with double glazed windows and doors

Warmer and drier for better home comfort

  • Windows are a huge part of your home’s appeal. They give you natural light, connect you to your outdoor spaces and make every room feel more open, airy and alive while keeping the exterior elements at bay.

  • How much does it cost to retrofit? Retrofit double glazing is a more affordable option than getting new joinery. It is a very difficult process to offer an approximate price before assessing the home. When we assess the home, we are looking for several different variables that will achieve the desired results in your home and, in turn, contribute to the cost of the retrofit installation.
    These variables include:

    • The age, condition of your existing joinery, volume of glass and access to your home.

    • Compatibility of your existing joinery with new double glazed units.

    • Double glazing makeup requirements to comply with the current Building Code, and achieve the desired performance results.

    If you would like an approximate estimate you could ring us at 0800 658 658 or email our local branch (view branch list) with some measurements and we can provide a rough ballpark if you prefer.
