Local Detail
Bi-fold doors fitted across Chelmsford
Chelmsford has one of the broadest property mixes in Essex — Edwardian terraces around Moulsham, 1930s semis through Broomfield, and rapid new-build growth at Beaulieu Park and Channels. Each comes with its own glazing brief, and a Springfield bay-window replacement looks nothing like a Beaulieu Park bi-fold install.
Our fitting van runs the A12, A130 and A414 most weeks, which is why a typical Chelmsford survey is in the diary inside three to five working days. Installs are handled by a in-house fitting team — same crew on day one and day five.
We're regularly on rear extensions in Great Baddow and Writtle, full-house window replacements in Springfield, and roof-lantern fits on single-storey extensions across the CM1 and CM2 postcodes. Chelmsford City Council is the local authority for Certass notification and building control — both handled on your behalf as standard.
Housing stock we work with here: Edwardian terraces, 1930s semis, post-war semis, and large quantities of recent new-build (Beaulieu Park, Channels, Springfield).
Our vans are around Chelmsford Cathedral, Hylands Park, Central Park most weeks, so survey and aftercare visits in Chelmsford are easy to diarise.

What goes wrong
Bi-fold problems we get called out to in Chelmsford
Failed sealed units in 1990s estates
A lot of Springfield and Great Baddow housing stock was glazed in the early '90s. Sealed units have a 20–25-year service life, and the misting and condensation we get called out to is almost always end-of-life seal failure rather than poor cleaning.
Draughty Edwardian sash windows in Moulsham
Original sashes around Moulsham and Old Moulsham can be carefully refurbished or replaced like-for-like with timber-effect frames, improving U-values while keeping the period appearance — important in conservation areas.
Bi-fold tracks fouling on uneven extension floors
We see this often on owner-built extensions in the CM2 area. The bottom track needs to be perfectly level — we shim or re-bed where needed at survey, before we order the doors.
New-build window seal degradation
Several Beaulieu Park and Channels-era homes are now 8–12 years in and seeing first-run gasket failure. A replacement gasket set extends frame life by another decade.

Manufacture
Frames are made to your surveyed sizes. We confirm the install date once they leave the factory.
-
04
Installation
Old doors out, track laser-levelled and DPM'd, frames set square, every panel tested through its full fold before we leave.
-
05
Sign-off & guarantee
Operation walk-through, Certass notification within 30 days, and a 10-year workmanship guarantee in writing.
