Your Questions Answered
How much should I budget for double glazing?
It depends on the size, style, material and glass of each window, so we don’t publish a price list. After a free survey we give you a fixed, written quote with no pressure to buy. For a rough idea before we visit, call us with the number and approximate sizes of your windows.
Is the government giving grants for double glazing?
Grant schemes change often and usually depend on your income, benefits and your home’s energy rating. Check the latest schemes on GOV.UK or with your local council, and we’re happy to talk through your options.
Is it worth replacing 20-year-old double glazing?
Often, yes. Older double glazing loses its thermal efficiency, leading to higher energy bills. Modern A-rated windows give better insulation, noise reduction and security. If you notice condensation, draughts or cold spots, it’s time to look at an upgrade – and if the frames are still sound, replacing just the glass may be enough.
