Window and door replacement will depend heavily on the type of unit you’re looking to install, as well as the number of frames and panes you’re looking to replace. As a lower estimate, we estimate around £500 per window for your home. Doors are harder to estimate, as they come in many more styles and types – but we would estimate a low-end cost of around £1000. This is a price to supply and fit your products, we recommend speaking to one of our office staff if you would like a more precise quotation.
