How much do new windows cost?

Facet Pro is in beta. Our measurement of wall area from a photograph is still being calibrated against surveyed properties, so treat wall and roof figures as indicative and window figures as a guide.

What moves the number, in order

How many windows, then how big they are, then how many of them open. An opening light is a hinge, a lock and a sealed frame, and it costs about the same whatever size window it goes in — so a fixed pane and a window with two openers can differ by well over a third for the same hole in the wall. Nobody can tell which you have from a photograph, which is why we ask.

Colour is the smallest of the four and the one people expect to be the biggest. Anthracite, black or a woodgrain finish adds a single-figure percentage, not a category.

Every figure above is a typical house. Yours is not typical — nobody's is. Upload one photograph and we will find your windows, doors, roof and walls, estimate your wall area, and price your own elevation.

These are estimates for planning, from real supplier and labour rates — not a quotation, and not a survey. What you pay depends on your own house and, more than anything else, on which company quotes it. Your installer confirms the figure on survey.
