What happens after you enquire
Every job in the SG1 district follows the same steps: price online, survey, written quote, made-to-measure manufacture and fitting, with the compliance certificate sent to you.
Approvals in England
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Sliding doors in Stevenage: questions
Can you widen my opening in Stevenage?
Yes. We can form or widen an opening for a larger sliding door, with structural calculations, a steel beam and English approvals arranged. That work is quoted alongside the door.
How much are sliding doors in Stevenage?
Guide prices are the same across mainland Britain. A 2.4 m wide aluminium door is a guide £4,295–£5,295, fitted, including VAT; uPVC starts from £1,695. Your exact price is fixed after survey.
Which sliding door suits a home in Stevenage?
It depends on the opening and budget. uPVC is the lowest-cost option for openings up to about 3.6 m; aluminium gives slimmer frames and wider spans; slimline and lift and slide suit large, high-end openings. The survey in Stevenage is the place to settle it.
