Local Detail
Bi-fold doors fitted across Hertford
Hertford runs heavily to Georgian and Victorian townhouses through the centre, with larger detached housing through Bengeo, Hertingfordbury and Bayford. Conservatories and properly glazed garden-room extensions outnumber simple window replacements in our SG13/SG14 workload by a comfortable margin.
Ware adds a strong run of 1930s and post-war semi-detached, where bi-fold installations on rear extensions are the typical brief. The same fitting team covers both ends of the borough.
East Herts District Council handles building control across the area, and most modern conservatories under permitted development don't need full planning. We'll flag anything that does at survey. Quote slots typically diaried inside six working days for SG postcodes.
Housing stock we work with here: Georgian and Victorian townhouses in central Hertford, large detached homes in Bengeo and Hertingfordbury, and 1930s/post-war semis through Ware.
Our vans are around Hertford Castle, the River Lea, the Hertford East and North stations most weeks, so survey and aftercare visits in Hertford are easy to diarise.
Why Us
Why Hertford homeowners choose us for bi-folds
Glazed extension specialists
Lean-tos, gable-fronts and full garden rooms — premium aluminium specification matched to Hertford's period housing.
Permitted-development experienced
We know what falls inside PDR and what needs full planning across East Herts. Survey covers the consent route upfront.
Survey within 4–6 working days
Hertford is at the outer edge of our run, so quote turnaround is slightly longer than core Essex — but install standards and warranty are identical.
In-House Fitting Team
Same crew on every Hertford project. Both fitters experienced, both in-house, not agency.
Premium aluminium specification
leading aluminium and roof lantern systems carry the bulk of Hertford garden-room and bi-fold work. We won't propose budget systems on premium homes.
10-year workmanship guarantee
Every Hertford install — written into your quote. Aftercare adjustments included for 12 months.
What goes wrong
Bi-fold problems we get called out to in Hertford
Outdated PVC conservatories with poor U-values
1990s-era conservatory frames lose enormous heat. Modern aluminium and properly insulated glass roofs make these spaces usable year-round.
Original timber sashes on Georgian townhouses
Conservation rules in central Hertford typically rule out modern replacements. Careful refurbishment or timber-effect like-for-like is the usual route — we'll confirm what's permitted at survey.
Garden rooms cut without structural sign-off
Some Hertford rear-extension work has been done without proper calcs. We'll insist on a structural sign-off before doors are ordered for openings over 2.4m.
Conservatory roofs leaking at the box gutter
Common on older lean-tos against the original house wall. Re-detail or replacement is the right answer — patch repairs rarely hold.
