New build, extension and self build projects
Why bi-fold doors look different to new build, extension and self build projects
Written for extensions, garden rooms and self builds where the opening is being formed rather than reused. The critical items are the structural opening sizes, the weatherproofing detail and when we can get on site relative to the brickwork.
The things worth checking before you accept a price
- Structural opening sizes agreed and issued to the builder in writing
- Thermal performance figures for the SAP or Part L calculation
- The internal architrave is coped rather than mitred where the reveal wall is out of true.
- The lead fitter photographs the reveal condition before the old frame comes out and shares those photos with the office.
Performance figures supplied in writing for building control and SAP calculations
What we typically find on bi-fold doors surveys around here
- ·The door-side glazed sidelight has a shattered internal pane held together by the laminated interlayer.
- ·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
- ·Original security stickers from the installer are still on the bottom of the panes, twenty years later.
- ·The top vent has been kept permanently closed with a wooden shim wedged inside the frame.
- ·The internal glazing bead across the top of the bay lifts out completely with fingernail pressure.
- ·Two units have the classic dust ring inside the sealed gap, meaning the perimeter seal has been breached for at least a year.
- ·The hinges are all dropped one notch from level, taking the sash out of square against the outer frame.
- ·The catch keep for the bathroom window has been packed out with a folded matchbox to make the sash lock.
- ·The bottom rail on the sash has taken years of rain runoff and swollen enough to bind on the frame.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
- ·There is a hairline crack running diagonally from the top corner of one bathroom pane where the frame has twisted.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·The internal window board has swelled at the sink end from years of splash and is delaminating along the front edge.
- ·A previous fitter foam-filled the reveal gap directly against the frame, and the foam has now pushed the jamb inward.
- ·The cylinder on the front door still has the builder's key stamp, meaning it has never been changed since handover.
Why residents are booking bi-fold doors right now
- ·The buyer wants the front door delivered pre-hung and pre-glazed on the same date as the frames.
- ·The owner is done with rattling frames in a westerly and wants a demonstrable acoustic upgrade, not a numerical claim.
- ·The homeowner wants the back door to be a family door — kids in and out, and no one having to slam it to lock.
- ·The owner is preparing the property for a rental switch and wants glazing to hit HMO fire-escape spec.
- ·The customer wants a specific hardware colour to match a kitchen renovation booked six months out.
- ·The owner is done with the sliding door drag and wants one that closes with a single push.
- ·The homeowner wants the composite front door to survive a decade of coastal salt without going chalky.
- ·The resident is on a listed street and wants a front door that will pass Article 4 first time.
- ·The homeowner is done with the whistle the front door letterplate makes in a north wind.
- ·The homeowner wants a single date, a single crew, and a single guarantee — not a paper trail across three companies.
- ·The buyer wants a composite front door that reads more house-proud than the run of identical rentals on the road.
- ·The buyer wants a genuine Which? Trusted Trader install, not a subcontracted crew running the badge.
- ·The owner is done reheating rooms every hour because the frames leak the heat straight back out again.
- ·The homeowner is preparing the property for a smart-home installation and wants sensor pockets designed into the reveals.
- ·The owner wants the whole property refurbished for a big family gathering nine weeks out — everything sequenced tightly.
- ·The resident wants an installer who will point out things the current property is doing well and leave those alone.
How our fitters actually do the work
- ·Cavity closers get inserted where the old frame's cavity closer has failed — not omitted because it is unseen work.
- ·The trickle-vent covers are set with their vane orientation matched across a bank of windows for visual consistency.
- ·The friction stay on a new casement is set to the client's preferred restraint at handover — 45°, 90°, or fully open.
- ·The bathroom obscure glass pattern is confirmed with a physical sample against the existing pane, not chosen from a brochure image.
- ·The old frame's fixing holes in the brick are filled and made good before the new outer frame beads up to the reveal.
- ·The frame is plumbed on two axes before the first fixing goes in — not one axis and then trusted.
- ·The client's Wi-Fi router near the door is checked for a signal drop after the composite slab is fitted — a rare case, but worth confirming.
- ·The internal cill support is packed with hardwood the full depth of the cill, not just at the ends.
- ·The glass has a factory kite mark visible at handover — not scraped off by a lazy cleaner during the fitting hour.
- ·The old cylinder is disposed of by the crew, not left in a bag on the drive for the client to bin.
- ·The bay assembly is squared with a laser diagonal, not a tape measure and eye.
- ·The lead fitter leaves a handwritten note of anything the client should watch in the first month, not a printed generic checklist.
- ·The composite door slab is inspected under torchlight for delamination before the hinges are fitted.
- ·The bead-in tools are rubber-faced, not steel — a steel tool marks the profile within minutes.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.
- ·The finished elevation is photographed from the pavement and uploaded to the office job file as sign-off record.

Faults we fix before recommending bi-fold doors
A sliding door that fights you is nearly always rollers and track debris, not a dead door.
French doors are a pair, so the fault is usually in how the two leaves meet rather than in either leaf on its own.
Most of the heat leaves through the roof and the frames, so that's where the money should go first.
