French and patio door quotes for Birmingham extensions and semis

Legacy Windows is a quote comparison service that matches you with installers already handling the structural notice, threshold detailing and Part L glazed-area maths that Birmingham City Council building control expects on garden-room extensions.

Frequently asked questions
Do French doors need a Building Notice in Birmingham? Replacing a door on an existing opening is covered by FENSA or CERTASS self-certification. Widening the opening or removing a wall requires a Building Notice submitted to Birmingham City Council building control, with structural calculations for the new lintel.
What glass spec meets Part L on a Sutton Coldfield extension? For an extension counted as a new element under Part L1B, the door glazed-area target is Uw ≤ 1.4 W/m²K with a G-value that limits summer overheating. Most Birmingham quotes we see come in at Uw 1.2 W/m²K on argon-filled A-rated units.
Are bifolds worth the extra cost over patio sliders in a Birmingham garden? Bifolds retract fully but need track depth and a place to stack the doors, and they cost 30 to 60 per cent more than a sliding patio on the same opening. On a typical 2.4m rear-extension opening in Hall Green, a two-pane patio slider often gives a better value-to-view ratio.
