[Get a Free Quote](/contact/) [07903 632039](tel:+447903632039) CM1, CM2 and CM3 · Surveys in 3–5 working days · 10-year workmanship guarantee 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. Why Us ## Why Chelmsford homeowners choose us for bi-folds ### Local fitting team, not agency The Chelmsford install crew is in-house, not agency — two in-house fitters who run every job from first cut to final clean. ### Survey within 3–5 working days Quote slots run 7am–8pm seven days. We hold capacity specifically for CM1–CM3 enquiries so you're not waiting weeks. ### Aluminium specialists in CM postcodes leading aluminium and roof lantern systems all installed weekly in Chelmsford. Premium aluminium is our largest single product line. ### Workmanship guarantee in writing 10 years on installation, separate to the manufacturer warranty. Aftercare adjustments in the first 12 months are included. ### Council-side admin handled Certass notifications and building control liaison with Chelmsford City Council are included as standard, no extra charge. ### Honest pricing Itemised quotes — frames, glass, fitting, disposal. No vague 'fully fitted' line items hiding extras. 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. Process ## How a Chelmsford bi-fold install runs 1. 01 ### Free survey We measure the opening, check the threshold and the lintel, and talk through pane counts and stacking direction on site. 2. 02 ### Configuration & spec Pane split, stacking side, traffic door position, RAL frame colour, glass spec and threshold type — all confirmed in writing. 3. 03 ### Manufacture Frames are made to your surveyed sizes. We confirm the install date once they leave the factory. 4. 04 ### Installation Old doors out, track laser-levelled and DPM'd, frames set square, every panel tested through its full fold before we leave. 5. 05 ### Sign-off & guarantee Operation walk-through, Certass notification within 30 days, and a 10-year workmanship guarantee in writing.
