Aluminium Bi-Fold Doors in Pontypool
For homeowners updating long-held family houses, landlords improving EPC ratings in Pontypool, bi-fold doors aren't a vanity upgrade — they're the single biggest fix for hill exposure and high wind loading on south-facing elevations. We supply 2, 3, 4 or 5-leaf configurations as standard, with matt anthracite, black, dual-colour inside/outside on request. Designed for 20,000+ open-close cycles before the running gear needs servicing, which matters when the next Mamhilad Park Estate car park gets built and your elevation faces it head-on.

New build, extension and self build projects
Buying bi-fold doors as new build, extension and self build projects
For projects still on paper, this page explains what we need from the drawings, what lead times look like, and how glazing is coordinated with the rest of the programme.
What this buyer actually needs from us
- Structural opening sizes agreed and issued to the builder in writing
- Building regulations compliant ventilation and safety glazing specified up front
- The client's alarm sensors on the old frames are removed and returned to the client, not binned by default.
- Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
Full insurance and a written guarantee that survives the handover to the homeowner
What we typically find on bi-fold doors surveys around here
- ·The multipoint gearbox on the front door still throws, but the hooks miss the keeps by 2mm on the middle throw.
- ·The gasket at the vent has perished and pulled away from its channel in two-inch sections.
- ·A weep vent that was factory-drilled has been over-painted three times and no longer clears water from the chamber.
- ·One sash sits proud of the frame by 2mm along the top rail — a factory manufacturing tolerance that never got addressed.
- ·The letterbox opening is not draught-proofed at all — a candle held two feet away flickers in a light wind.
- ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
- ·The front door threshold weather-bar seal is missing its rubber blade and the metal channel is bent.
- ·A previous decorator's dust sheet was left inside the frame chamber during a repaint and is still there.
- ·A previous fitter drilled through the outer frame chamber for the trickle vent — never fully sealed the drilling.
- ·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
- ·The porch canopy has been leaking directly onto the top of the door for years — the top edge of the slab is soft.
- ·The front door has been painted three times without stripping — the paint film is now stopping the door closing at the top.
- ·The kitchen window has a defrost line across the low-e coating — argon gas long gone.
- ·There is no drip groove on the underside of the cill — water tracks straight back onto the brick face.
- ·The door-side glazed sidelight has a shattered internal pane held together by the laminated interlayer.
- ·Original security stickers from the installer are still on the bottom of the panes, twenty years later.

- ·The resident wants the noise of the school run down and the light from the morning sun up.
- ·The buyer wants a composite door slab that a courier's boot cannot dent when a delivery is fumbled.
- ·The resident is moving elderly parents in downstairs and needs the front threshold to be wheelchair-usable.
- ·The owner is done with rattling frames in a westerly and wants a demonstrable acoustic upgrade, not a numerical claim.
- ·The homeowner wants the composite front door to survive a decade of coastal salt without going chalky.
- ·The homeowner has quotes for a new kitchen next spring and wants the patio doors in before those trades arrive.
- ·The resident has a shift-worker sleeping in the day and needs the bedroom to be a genuine acoustic step change.

- ·The homeowner has finally accepted the timber back door is beyond another repaint and wants the like-for-like replacement design chosen with them.
- ·The owner wants the master bedroom quiet enough for a night-shift partner to sleep past 11am.
How our fitters actually do the work
- ·The old broken glass is bagged in a labelled sack, not tipped loose into a general skip.
- ·The gasket at the corner mitre is butt-jointed with a fresh knife cut, not stretched and hoped.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise, checked with a spirit-level lip.
- ·Sealant is a single continuous bead run at the perimeter, not overlapped in six-inch runs.
- ·The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·The composite slab is not trimmed on site — if it doesn't fit, a new slab is ordered rather than reduced.
- ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
- ·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 internal trim goes on with pin nails through the flange, not straight through the visible face.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
- ·The van carries a set of dust extraction attachments and uses them on any grinder work in occupied rooms.
- ·Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
- ·The letterplate is fitted with the internal flap set to close under its own weight without dragging.
- ·The frame is protected with a low-tack film across any face a tool might touch during the fitting hour.
- ·The dustsheet inside the room is a heavy canvas taped to the skirting, not a light plastic left loose.
- ·The frame perimeter sealant is a low-modulus polymer where the substrate is going to move — plain silicone otherwise.

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.
