Bi-fold doors fitted across Caerleon & NP18
If you're looking at bi-fold doors for a home in Caerleon, you're probably dealing with conservation-area rules on frame profile and colour or damp rising from the Usk floodplain on the lower streets — both common in the Roman-era heritage streets, stone cottages near the amphitheatre, Victorian terraces along the High Street and 90s executive builds on Roman Reach you find across NP18. We've fitted hundreds of sets across Ultra Pontem, Bulmore and Ponthir, all signed off under Newport City Council building standards. Anthracite leaves match the stone of Welsh garden walls; thermal break copes with the wet winters.

New build, extension and self build projects
Who this page is for: new build, extension and self build projects in Caerleon
On new work the frame arrives into an opening built to our schedule, so getting the sizes agreed early is the whole job. This page covers how we work alongside the builder rather than after them.
What we build into the quote for you
- Cill, lintel and cavity closer details resolved before frames are ordered
- Thermal performance figures for the SAP or Part L calculation
- The bead-in tools are rubber-faced, not steel — a steel tool marks the profile within minutes.
- The glass has a factory kite mark visible at handover — not scraped off by a lazy cleaner during the fitting hour.
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 trickle vents are painted shut and the room fugs up within an hour of the kettle going on.
- ·The outer frame has moved fractionally over the years, dropping the bottom hinge screw pattern out of line.
- ·The bathroom pane is patterned glass from the original build, and the pattern is no longer a current stock line.
- ·A homemade timber threshold has been screwed to the concrete cill in front of the patio door.
- ·The composite door slab has a hairline crack along the letterplate cut-out from a delivery boot.
- ·The front door has been painted three times without stripping — the paint film is now stopping the door closing at the top.
- ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
- ·The old timber sub-frame under the current uPVC unit is still in place and is soft at the bottom left corner.
- ·The transom bar has a live crack in the plastic, opened up by summer expansion cycles.
- ·The frame drainage slots at the bottom are clogged with debris, so rainwater sits inside the chamber.
- ·The friction hinge on one window sticks at 45° open and needs the palm of a hand to nudge past.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·The trickle-vent screw covers are missing and the internal chamber has filled with cobweb.
- ·One casement's friction stay has been swapped for a random spare that doesn't match the arm geometry.
- ·The glazing spacer bars are aluminium, not warm-edge — a decade behind current U-value expectation.
- ·The bottom hinge on the front door has torn its top screw fixing free of the frame.
Why residents are booking bi-fold doors right now
- ·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 homeowner has an infrared thermometer and has been point-checking the frames — they want the readings up by ten degrees.
- ·The owner wants the front door hardware to match a specific interior palette — brass, matt black, or brushed nickel.
- ·The buyer is done with the sound of the frames rattling in a gale.
- ·The owner is done with the biannual repaint of the timber back door and wants a paint-free equivalent.
- ·The owner wants the master bedroom quiet enough for a night-shift partner to sleep past 11am.
- ·The owner is having a kitchen refit next month and wants the patio door in first so the tiler works to a fitted threshold.
- ·The resident is expecting an elderly parent to move in and needs a door that opens without a shove.
- ·The homeowner wants the property EPC to move up a band ahead of a remortgage in six months.
- ·The buyer wants the frames to still look right in twenty years, not just at handover.
- ·The homeowner has quotes from two national companies and wants a local one to be honest about the same job.
- ·The homeowner wants a five-star Checkatrade installer at the door, not a subcontracted crew nobody has vetted.
- ·The homeowner wants a single date, a single crew, and a single guarantee — not a paper trail across three companies.
- ·A newborn has arrived and the parents want the nursery to hold a stable overnight temperature.
- ·The owner is buying and wants to time the frame swap for the week between exchange and moving in.
- ·The owner is dealing with a partner who works nights and needs the bedroom acoustically watertight before summer.
How our fitters actually do the work
- ·The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
- ·Every silicone bead is tooled with the correct radius spatula, not smoothed with a wet finger only.
- ·The frame perimeter is checked with a smoke pencil for airtightness before the internal trims go on.
- ·The reveal is brushed down and vacuumed before any sealant runs, so the bead adheres to substrate, not dust.
- ·The gasket wedges are trimmed with a fresh knife blade for every unit — a dull blade tears the EPDM.
- ·The client is walked through the finished job with a printed operation card, not a rushed verbal handover.
- ·The internal trim goes on with pin nails through the flange, not straight through the visible face.
- ·The frame square is checked at the diagonals before any glass goes in — a square frame stays square.
- ·The perimeter tape between frame and reveal is a compressible foam tape, not a plain butyl strip.
- ·The threshold is bedded on butyl mastic under the outer skin, giving the fitter a second waterproof line behind the perimeter silicone.
- ·The frame reinforcement steel is confirmed by knock-test before selecting the fixing pattern.
- ·The letterplate is fitted with the internal flap set to close under its own weight without dragging.
- ·The bead-in tools are rubber-faced, not steel — a steel tool marks the profile within minutes.
- ·The van carries a set of dust extraction attachments and uses them on any grinder work in occupied rooms.
- ·The internal skirting is protected with a strip of packing tape across the top edge before any tool touches it.
- ·The fitting van is stocked with the specific spare parts likely to be needed on the day — not a return trip on a missing hinge.
FAQs — bi-fold doors in Caerleon
Will bi-fold doors suit the older Roman-era heritage streets common around Caerleon?+
Anthracite leaves match the stone of Welsh garden walls; thermal break copes with the wet winters. We've installed dozens in Ultra Pontem and Bulmore alone.
Do you do commercial bi-fold doors for sites near Celtic Manor?+
Yes. We've worked across Celtic Manor and Coldra Park to the south, supplying the same thermally broken aluminium leaves build we use on residential. Commercial quotes include site access notes and out-of-hours options.
Why replace the whole set rather than one-by-one in a Caerleon home?+
Because wanting to fold the back wall away without losing security or thermal performance rarely stays isolated — once one unit goes, the rest follow within a few years. Doing it once means matching frames across the elevation and one trip for our team into NP18.
Can bi-fold doors handle conservation-area rules on frame profile and colour?+
Directly, yes — designed for 20,000+ open-close cycles before the running gear needs servicing. That matters in Caerleon where conservation-area rules on frame profile and colour is the single most common reason people call us.
What colours and finishes are available for bi-fold doors?+
2, 3, 4 or 5-leaf configurations; matt anthracite, black, dual-colour inside/outside. We bring physical samples to the quote so you can see them against your Roman-era heritage streets in real light.
Do you work from architect's drawings?+
Yes. Send the elevations and we will return structural opening sizes, cill details and the glazing specification in writing so the openings are formed correctly.
Can you supply performance figures for building control?+
Yes. U values, ventilation provision and safety glazing positions are supplied in writing with the quotation for the SAP or Part L submission.

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.
