New bi-fold doors for Newport homes
Most of our bi-fold doors jobs in Newport start with the same call: "wanting to fold the back wall away without losing security or thermal performance". Around here that usually means a long Victorian and Edwardian bay fronted terraces through Maindee and Stow Hill where the original frames have given up. We work right across NP19 and NP20 and NP10 — Maindee, Rogerstone, Allt-yr-yn and the surrounding streets — typically arriving via M4 J24 to J28. Structural opening surveyed for deflection, head track set straight to within 2mm, leaves hung and adjusted across multiple visits if needed.

Who this page is for: commercial premises, offices and managed sites in Newport
This page covers commercial rather than domestic work. Access, out of hours working and keeping the premises trading through the installation are the constraints that shape the quote.
What we build into the quote for you
- One invoice with a purchase order reference for the finance team
- A programme that is confirmed in writing rather than provisional
- The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
- The crew leaves the client with a printed adjustment card so the multipoint keeps can be re-set six months on without a callout.

What we typically find on bi-fold doors surveys around here
- ·The internal locking cams on the multipoint have been ground down by a mismatched keep pattern.
- ·One kitchen unit has a defrost trace across the low-e coating — the argon fill has been gone a while.
- ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
- ·The concrete cill under the door has heaved by 3mm across the two-metre span, tilting the whole threshold.
- ·One sash sits proud of the frame by 2mm along the top rail — a factory manufacturing tolerance that never got addressed.
- ·There is a live crack running from the top corner of a bay-window pane where the frame has been out of square since installation.
- ·One handle turns freely through 180° with no engagement — a snapped internal cam.
- ·The old aluminium sliding door has grit in the track that has worn the roller wheels to elliptical.
- ·The internal window board has swelled at the sink end from years of splash and is delaminating along the front edge.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·A weep vent that was factory-drilled has been over-painted three times and no longer clears water from the chamber.
- ·The glazing spacer bars are aluminium, not warm-edge — a decade behind current U-value expectation.
- ·The internal glazing bead across the top of the bay lifts out completely with fingernail pressure.
- ·The trickle-vent covers have been snapped off and taped over from inside.
- ·The escutcheon plate on the back door hides a botched cylinder swap where the follower is worn.
- ·The porch-roof lead flashing has been dropping water onto the head of the front door for years.
Why residents are booking bi-fold doors right now
- ·The resident is moving elderly parents in downstairs and needs the front threshold to be wheelchair-usable.
- ·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.
- ·The buyer wants the porch to stay a porch and not turn into a mud room by function.
- ·The owner wants the whole property refurbished for a big family gathering nine weeks out — everything sequenced tightly.
- ·A recent break-in on the street has moved security up the priority list ahead of aesthetics.
- ·The buyer wants the front door delivered pre-hung and pre-glazed on the same date as the frames.
- ·The homeowner wants a five-star Checkatrade installer at the door, not a subcontracted crew nobody has vetted.
- ·The buyer wants no upsell scripts — a survey, a spec, a figure, and space to think.
- ·The buyer is moving in with two dogs and needs a back door that will not degrade with claw scrape.
- ·The insurance renewal notice flagged a locks upgrade requirement and the owner wants it done before the policy anniversary.
- ·The buyer wants a full set of the same colour across every elevation, not the current mixed collection.
- ·The resident wants the front to look distinct on a street of five identical houses.
- ·The owner has an ageing parent visiting for extended stays and wants the guest bedroom warmer than it currently is.
- ·The owner is preparing the elevation for a specific street-photo listing and wants the finish to be photographable in raking morning light.
- ·The owner is done paying to service failing 90s uPVC every couple of years and wants the whole set replaced together.
How our fitters actually do the work
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The trim between the frame and the plaster line goes on last, after the sealant has set and been proven leak-tight.
- ·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
- ·The multipoint hooks are lightly greased after fitting, before the door is closed for the first time.
- ·The lock cylinder is measured for internal and external protrusion — a cylinder that stands proud is a snap risk.
- ·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 trickle-vent covers are set with their vane orientation matched across a bank of windows for visual consistency.
- ·Any dropped hinges on the existing door are noted before the swap so the new frame is set for the correct drop.
- ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
- ·The multipoint keeps get a smear of grease inside the pocket before the door is closed for the first time.
- ·The keeps for the multipoint are set with the door open and the position marked, not adjusted by eye once the door is closed.
- ·The internal make-good caulk is polymer, tooled with a wet finger and then a spatula for a final radius.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise, checked with a spirit-level lip.
- ·The multipoint gearbox is thrown by hand before the frame goes in — a factory fault at that point is a five-minute fix.

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.
