Local Detail
Bi-fold doors fitted across Kent
Kent is a substantial secondary catchment for us — the QE2 crossing puts North Kent within an hour of our Essex base, and we run regular bi-fold and aluminium glazing installs through DA and ME postcodes.
Larger projects through TN and CT — typically full-house glazing or substantial extension bi-folds — are quoted on a project basis with a confirmed install window. Smaller single-door jobs in deeper Kent we'll discuss honestly before booking.
Quote slots typically diaried inside seven working days for Kent. Local building control varies by district; Certass notification handled by us regardless of authority.
Housing stock we work with here: Substantial detached and Edwardian housing through North Kent, period cottages in the Weald, modern estates around Maidstone.
Our vans are around the QE2 Bridge, the M25 / M26 corridor, the Medway Towns most weeks, so survey and aftercare visits in Kent are easy to diarise.

What goes wrong
Bi-fold problems we get called out to in Kent
Bi-fold tracks fouling on uneven thresholds
Most Kent bi-fold callbacks we get asked to fix are tracks that weren't shimmed level at install. Once a track's twisted, the doors won't sit square. We level and DPM every threshold at survey, before doors are ordered.
Underspecified pane sizes
Aluminium bi-folds can run pane sizes most installers won't quote — but only with the right system and the right glass. Going too small for the opening costs you light and visual width. We size to the opening, not to a default catalogue.
Cheap PVC bi-folds in large openings
PVC bi-folds work in small openings but the frames are bulky and the pane size is restricted. For most Kent rear extensions, aluminium gives slimmer sightlines and a 25–30-year frame life — usually the right call.
Hardware corrosion from coastal/exposed sites
Marine-grade hardware matters for any Kent install with significant exposure. We specify upgraded rollers and locks where the site demands it — standard hardware doesn't last in the wrong location.
