Triple glazed bifold doors in South Croydon
From the first measure to the handover pack, we handle triple glazed bifold doors for homes in South Croydon and the rest of Greater London.
Slim, strong bifolds rated for heavy triple glass. Bifold doors are made of several panels hinged together that fold and slide to one or both sides, opening almost the full width of the opening.
Winter light and glass choice in South Croydon

Rules for bifold doors in England
In England, replacement external doors must meet 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
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- Free survey and a written quote fixed for the specification
