"The cost of replacing existing French doors with new uPVC sliding patio doors will depend on the size, colour, glazing specification, and overall design selected. As a general guide, most installations are typically in the region of £1,600–£2,000 including VAT, supplied and professionally fitted.

For a more accurate quotation, a survey and measurement would be required.
