Bi-fold briefs are typically rear-extension projects on the modern stock. Conservation rules apply in central CM23 — we flag listed-building or conservation-area constraints at survey. Modern aluminium is rarely permitted on protected frontages, but rear extensions almost always permit it. Quote slots typically diaried inside six working days for CM23. East Herts District Council handles building control. Certass notification included as standard. **Housing stock we work with here:** Georgian and Victorian central townhouses, substantial modern detached, period cottages in surrounding villages. Our vans are around Bishop's Stortford station, Stansted Airport, the M11 corridor most weeks, so survey and aftercare visits in Bishop's Stortford are easy to diarise. Why Us ## Why Bishop's Stortford homeowners choose us for bi-folds ### Bi-fold specialists in Bishop's Stortford leading aluminium systems aluminium systems installed weekly in Bishop's Stortford. Premium aluminium bi-folds are our single largest product line — not a sideline. ### Own in-house fitting team The same Certass-trained crew on every Bishop's Stortford install — no agency labour, no rotating sub-contractors.

The number on the page is the number you pay — no surprise extras after install. ### Threshold detailing done properly Bi-fold tracks have to be perfectly level and properly DPM'd. We get this right at survey — it's the single biggest cause of long-term callbacks if it's wrong. ### 10-year workmanship guarantee Every Bishop's Stortford install — written into your quote, separate to manufacturer warranty. Aftercare adjustments included for the first 12 months. What goes wrong ## Bi-fold problems we get called out to in Bishop's Stortford ### Bi-fold tracks fouling on uneven thresholds Most Bishop's Stortford 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 Bishop's Stortford 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 Bishop's Stortford install with significant exposure. We specify upgraded rollers and locks where the site demands it — standard hardware doesn't last in the wrong location. Process ## How a Bishop's Stortford 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.
