Triple glazed sliding patio doors in Greenford
Triple glazed sliding patio doors for homes in Greenford: measured on a free survey, made to order and fitted by installation teams working for us across Greater London.

uPVC and aluminium sliders with low-threshold options. A sliding patio door has large glazed panels that slide past each other on a track, so it opens without swinging into the room.
Winter light and glass choice in Greenford
By midsummer Greenford has about 16 h 38 min of daylight, but in December only around 7 h 49 min, with the noon sun at about 15°. Triple glazing keeps more heat in during those long, dark months; big south and west windows may suit solar-control glass for summer.

Rules for sliding patio doors in England
England sets replacement door limits through Approved Document L (2021 edition, with 2023 amendments): 1.4 W/m²K, or a door set energy rating of band C (more than 60% glazed) or band B (other doors). Replacement external doors fall under the same energy rules: a competent person scheme installer (such as FENSA or Certass) self-certifies the work and notifies the council, or a building control body approves it.
Before ordering: Replacing doors on a house is normally permitted development if the new ones look similar. Flats need planning permission for a change that alters their appearance, an Article 4 direction may mean permission is needed, and listed buildings need listed building consent.
How it works
The surveyor measures every opening, checks ventilation, escape windows and safety-glass zones, and talks through styles. Your written quote lists each item with its glass build-up and U-value, and the price is fixed for that specification.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
