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.

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.
