In this guide we cover the total cost of replacing / installing windows and doors in a home including labour and materials. Any window or door replacement should be carried out by an installer who’s a member of a government authorised Competent Persons Scheme (normally FENSA for windows and doors), this will ensure your windows/doors are installed in compliance with building regulations and installation registered with the local authority. Your old windows will be removed and the replacement windows fitted in place. They should be made to measure and any small gaps filled with expanding foam, with the final window being finished off neatly with trim.
Windows can either be double or triple glazed, that refers to how many sheets of glass there is in their construction, the more sheets the greater the level of thermal efficiency and noise insulation. The frames are commonly constructed out of either aluminium, wood or uPVC.
