New composite doors for Pontypridd homes
Most of our composite doors jobs in Pontypridd start with the same call: "old timber and rotten 90s uPVC front doors that leak heat, jam in winter and fail break-in standards". Around here that usually means a long rows of valley terraces with stone fronts where the original frames have given up. We work right across CF37 and CF38 — Treforest, Graig, Cilfynydd and the surrounding streets — typically arriving via A470. Old frame stripped on the day, new outer frame fitted plumb to the brick reveal, threshold sealed with EPDM and silicone.

This page is aimed at rental stock rather than owner occupied homes. The priorities are different: void periods, compliance, hardware that survives tenants, and a spend that can be justified against rent and EPC banding.
What we build into the quote for you
- Consistent specification across a portfolio so spares are interchangeable
- One invoice per property with each opening listed for the accounts
- The manufacturer's kite mark on the corner of the glass is left in place at handover — proof of spec for the next owner.
- The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
Written guarantees and insurance documentation supplied for the property file as standard

What we typically find on composite doors surveys around here
- ·The stay arm on the top vent has bent and no longer sits into its rest bracket cleanly.
- ·The letterbox opening is not draught-proofed at all — a candle held two feet away flickers in a light wind.
- ·The composite door slab has a hairline crack along the letterplate cut-out from a delivery boot.
- ·The trickle vent on the master bedroom has been foil-taped shut for warmth — condensation has doubled since.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·The top vent has been kept permanently closed with a wooden shim wedged inside the frame.
- ·A cracked pane has been temporarily patched with clear tape and left for six months.
- ·The old timber back door has a live rot pocket at the bottom hinge that reads soft to a screwdriver tip.
- ·The bottom track on the sliding door has a build-up of grit that the rollers grind through every open cycle.
- ·The composite front door skin has a shallow dent from a delivery bike handlebar and it has ovalised the door.
- ·Two units have the classic dust ring inside the sealed gap, meaning the perimeter seal has been breached for at least a year.
- ·There is no drip groove on the underside of the cill — water tracks straight back onto the brick face.
- ·The georgian bar between panes on one unit has slipped off its top spacer and is sitting diagonally inside the sealed cavity.
- ·The mid-rail on the composite door is bowed outward at the middle by 2mm — a slab-warp symptom.
- ·The sealed unit is a 20mm gap, not the modern 28mm minimum, so U-values are into the mid-2s at best.
- ·The old aluminium sliding door has a cracked head roller that pulls the door out of parallel with the frame.
Why residents are booking composite doors right now
- ·The buyer is running a small business from the home office and wants the kerb to say established and settled.
- ·The buyer is moving in with two dogs and needs a back door that will not degrade with claw scrape.
- ·The resident has already had one failed installation and wants to know exactly how this one will differ.
- ·The resident wants the whole property warm to bare feet on a January morning — the frames are the last variable.
- ·The owner has tried draught-excluder tape and a chimney balloon and now accepts the frames themselves are the cause.
- ·The homeowner is preparing to work from home permanently and wants the office quieter than the living room used to be.
- ·The buyer wants a genuine Which? Trusted Trader install, not a subcontracted crew running the badge.
- ·The buyer wants the sound of the sea audible but the wind noise gone.
- ·The resident cycles to work and wants a bike-in-porch design that a survey needs to plan around.
- ·The resident wants the crew to remove and re-hang the internal curtains as part of the job, not leave that step to them.
- ·The resident has already lost one composite door to a courier boot and wants the replacement rated for impact.
- ·A newborn has arrived and the parents want the nursery to hold a stable overnight temperature.
- ·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 resident wants an installer who will point out things the current property is doing well and leave those alone.
- ·The homeowner wants a single date, a single crew, and a single guarantee — not a paper trail across three companies.
- ·The resident has a shift-worker sleeping in the day and needs the bedroom to be a genuine acoustic step change.
How our fitters actually do the work
- ·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.
- ·The mitre joins on any Georgian bar are picked to face the corner that is least visible from indoors.
- ·Door thresholds are set with a spirit level along their full length and then re-checked with a straight edge.
- ·The gasket at the corner mitre is butt-jointed with a fresh knife cut, not stretched and hoped.
- ·Cavity closers get inserted where the old frame's cavity closer has failed — not omitted because it is unseen work.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·The composite door slab is inspected under torchlight for delamination before the hinges are fitted.
- ·The frame is protected with a low-tack tape at any point a tool might scrape it during the fitting hour.
- ·The old handles are offered to the client before being binned — sometimes a chrome D-handle finds a shed door life.
- ·The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·The old frame is removed by cutting the corners with a reciprocating saw rather than a lever bar that damages the reveal.
- ·The gasket is dressed into every corner with a specific gasket tool, not a screwdriver, so the corner stays sharp.
- ·The glazing bead is tapped in with a rubber mallet, not a metal claw — the profile marks otherwise.
- ·The bay assembly is squared with a laser diagonal, not a tape measure and eye.
- ·The crew calls the client at 5pm the day before to confirm arrival window and site access details.
- ·The internal cill support is packed with hardwood the full depth of the cill, not just at the ends.
FAQs — composite doors in Pontypridd
Will composite doors suit the older long rows of valley terraces with stone fronts common around Pontypridd?+
The 48mm slab clears most South Wales brick reveals without needing a packer; sidelights match Edwardian bay layouts. We've installed dozens in Treforest and Graig alone.
Do you cover Caerphilly and Cardiff as well?+
Yes — Caerphilly is roughly 10 miles from Pontypridd, Cardiff about 12. Same team, same prices, same guarantee.
How do you reach jobs in Pontypridd from your base?+
Direct down the A470 from our Caerphilly base — most quotes happen the same week — typically a direct run via A470.
What colours and finishes are available for composite doors?+
Solidor / Rockdoor style ranges; anthracite, navy, racing green, chartwell, black; brass, chrome or matt black hardware. We bring physical samples to the quote so you can see them against your long rows of valley terraces with stone fronts in real light.
Do you fit composite doors across all of Pontypridd?+
Yes — we work across every CF37 and CF38 postcode, from Treforest through to Graig, and out as far as Cilfynydd. Direct down the A470 from our Caerphilly base — most quotes happen the same week.
Can the work be done between tenancies?+
That is how most of our rental work runs. Give us the void dates at enquiry and we will confirm before you accept whether the programme fits inside them.
Will new windows move the EPC band?+
Replacing failed or single glazed units with A rated sealed units improves the fabric score. How far the band moves depends on heating, insulation and the rest of the assessment, so we will not promise a specific letter.
Solve damp from the river valley and frequent rain for good
Our composite doors use GRP weatherproof skin to fix the root cause — not patch it.

Faults we fix before recommending composite doors
A door that needs lifting, shoving or a second attempt to lock is warning you before the gearbox fails completely.
A composite slab that catches on the frame has almost always moved at the hinges, and hinges are adjustable in three planes.
Most break-ins through glazed openings exploit the cylinder or the keeps, both of which are upgradeable in an afternoon.
