[Get a Free Quote](/contact/) [07903 632039](tel:+447903632039) CM13, CM14 and CM15 · Surveys in 2–4 working days · 10-year workmanship guarantee Local Detail ## Bi-fold doors fitted across Brentwood Brentwood housing skews larger and more detached than most of Essex — 1930s mock-Tudor through Hutton and Shenfield, big interwar detached around Warley, and a rolling pipeline of side-return and rear extensions on Edwardian villas closer to the High Street. Roof lanterns and bi-folds together account for roughly 60% of our Brentwood workload. Crossrail at Shenfield has reshaped the local market and pushed rear-extension activity hard. We're frequently working on single-storey kitchen extensions where a 3m × 2m aluminium roof lantern is paired with a 4-pane bi-fold along the back wall. Our fitting van is in CM13–CM15 most weeks. Brentwood Borough Council handles building control for the area, and Certass-notified replacements don't need separate consent. Quote slots are normally booked inside two to four working days for Brentwood postcodes. **Housing stock we work with here:** Mock-Tudor detached, large interwar detached, Edwardian villas, and increasing extension/refurbishment activity post-Crossrail. Our vans are around Shenfield Crossrail station, Thorndon Country Park, Brentwood High Street most weeks, so survey and aftercare visits in Brentwood are easy to diarise. Why Us ## Why Brentwood homeowners choose us for bi-folds ### Roof-lantern installs by experienced fitters All Brentwood lantern installs are by fitters experienced in roof-lantern assembly standards — frame square, glass set, no twist. ### Survey within 2–4 working days Brentwood is on our regular run. Most CM13–CM15 enquiries are seen within four days, evenings and weekends included. ### Built for big rear extensions Bi-folds up to 6 panels, lanterns up to 4m × 2.5m. We've handled the full openings rear-extensions in Brentwood typically demand. ### Premium aluminium specification leading aluminium systems systems sit naturally in the Brentwood housing stock. We won't push PVC where aluminium is the right answer. ### End-to-end project handling Surveys, structural co-ordination, Certass notification and final clean — all in-house, no sub-contracted finger-pointing. ### In-house fitters The same in-house crew on every Brentwood job. They are part of our small in-house team — no agency labour. What goes wrong ## Bi-fold problems we get called out to in Brentwood ### Underspecified lanterns on big extensions We see a lot of 2m × 1m lanterns in Brentwood extensions where a 3m × 2m would have been the right call. Bigger isn't always better — but on a 5m-deep room you can see the difference. ### Bi-fold tracks set into damp screed Track corrosion shows up 5–7 years in if the install hasn't accounted for moisture rising through new screed. We DPM every threshold as standard. ### Listed-building restrictions in old Brentwood Properties around the conservation area can't always take aluminium replacement frames. We'll discuss the right route at survey, including timber-effect alternatives that keep the period appearance. ### Loft-conversion rooflights leaking at flashing Where a previous installer didn't dress the lead flashing properly. We re-detail flashings on every replacement rooflight, regardless of original fitter. Process ## How a Brentwood 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.
