Bi-fold Doors in Leicester

Thresholds, structure and why the survey comes first

We survey the threshold before we price a bi fold anywhere in Leicester (LE1–LE5), because on older properties the structure under a wide opening is the real variable. Getting a level, load bearing, properly drained threshold in place is the difference between doors that glide and doors that bind after one winter.

How we specify bi-fold doors here

Panels hung on a top running or bottom running track with hinged links between them, in aluminium or reinforced uPVC. The running gear carries all the weight and takes all the wear, so the hardware set is most of what you are paying for. A locking traffic door with multi point hooks and a 3 star cylinder, shootbolts on every intermediate panel, and laminated glass throughout. The stacked panels lock as one when closed.

• Quality running gear rated for the panel weight, adjusted on handover
• Traffic door with 3 star cylinder plus shootbolts on every panel
• Structural and threshold assessment included at survey before we quote
• From £2,650 fully fitted for a standard three panel set. Price rises with panel count and glass area, and the survey establishes whether the opening needs structural work first.
