    FAQs

    What is A rated double glazing?

    Energy efficiency is often the top priority and it’s no wonder as the bills keep rising. The British Fenestration Rating Council (BFRC) rates window energy performance and publishes results to help you decide which windows are best for you.

    How do you replace windows in an old house?

    Window frames can have a real impact on a property's thermal efficiency. Affecting old Victorian and Edwardian homes in particular, many homeowners are led to believe replacing windows in old houses is incredibly difficult - but it needn't be.

    How do I know if my windows need replacing?

    There are always obvious signs like poor fit, rot in wood, loose fittings, and inconsistent lock operation, but sometimes it’s just time for a change. New windows can have a big impact on the outward appearance of your home. See our blog for more on this
