How much do bi-fold doors cost in Theydon Bois?

Price depends on the opening width, the number of panes, the glass spec and the threshold detail, so we don't publish figures that would only mislead. Every Theydon Bois quote is itemised — frames, glass, fitting and disposal listed separately — after a free survey.

How quickly can you survey a bi-fold door job in Theydon Bois?

Most Theydon Bois surveys (CM16) are booked within 3–5 working days. Quote slots run 7am–8pm, seven days a week, and there's no deposit taken at the visit.

Do you fit aluminium or PVC bi-folds in Theydon Bois?

Aluminium is what we recommend and fit for almost every Theydon Bois project — slimmer sightlines, larger pane sizes and a far longer frame life. If you want to compare, read our guide on aluminium vs PVC bi-fold doors.

How long does a bi-fold installation take in Theydon Bois?

A straightforward replacement into an existing opening is usually a single day. If the opening is being formed or altered as part of an extension, we survey after first-fix and fit once the structural work and floor levels are finalised.

Which parts of Theydon Bois do you cover?

All of CM16, including Theydon Bois village, Coppice Row, Abridge border, Epping border. Same survey, same in-house fitting team and same guarantee wherever you are in the area.

Yes. Installations are Certass-notified on your behalf within 30 days, aluminium frames carry a 25–30 year manufacturer warranty depending on system, sealed units carry 10 years, and our workmanship is guaranteed for 10 years in writing.

What goes wrong

Bi-fold problems we get called out to in Theydon Bois

Bi-fold tracks fouling on uneven thresholds

Most Theydon Bois 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 Theydon Bois 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 Theydon Bois install with significant exposure. We specify upgraded rollers and locks where the site demands it — standard hardware doesn't last in the wrong location.
