Pontyclun composite doors — survey, supply & install

Pontyclun sits 2 miles from Llantrisant and 10 from Cardiff, and that's the patch this page covers. The composite front doors we fit here use 48mm solid composite slab and GRP weatherproof skin, which is what holds up against original 1990s-spec uPVC on estate homes now failing at the seals. Straight down the A470 then west on the A473 — Pontyclun is a 25-minute run from our Caerphilly base, so site visits and follow-ups don't drag.

Owner occupiers replacing one door or one window

Who this page is for: owner occupiers replacing one door or one window in Pontyclun

Written for people who need one opening sorted rather than a full refit. The honest question at this size of job is repair or replace, and this page answers it before asking you to book anything.

The things worth checking before you accept a price

  • A short arrival window rather than a whole day waiting in
  • The old unit removed and taken away the same day
  • The trim between the frame and the plaster line goes on last, after the sealant has set and been proven leak-tight.
  • The van carries a set of dust extraction attachments and uses them on any grinder work in occupied rooms.

The same ten year product guarantee applies whether you buy one unit or twenty

New front door fitted

Rosac fitted our new composite door — beautiful finish, friendly lads and tidy from start to finish. House already feels warmer. Highly recommended.

CF37 · April 2026
Full house of windows

Had every window in the house replaced. The team were punctual, polite and the quality is brilliant. Genuinely couldn't be happier.

Back door & patio doors

Replaced our back door and patio doors. Great communication, fair price and excellent workmanship. Will be using them again for the windows.

What we typically find on composite doors surveys around here

  • ·The reinforcement steel inside the top rail of a wide sash has rusted through in one corner.
  • ·One patio-door interlock has a bent alignment lug — the door jams shut half of the time.
  • ·Handles on the ground-floor windows have been swapped for cheap replacements that no longer match the espag rod.
  • ·Original beads have been over-painted so many times they no longer clip flush and rattle in a gust.
  • ·The frame drainage slots at the bottom are clogged with debris, so rainwater sits inside the chamber.
  • ·A cat flap has been cut through the lower panel of the back door, weakening the panel and voiding warranty.
  • ·The internal locking cams on the multipoint have been ground down by a mismatched keep pattern.
  • ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
  • ·The bottom rail on the sash has taken years of rain runoff and swollen enough to bind on the frame.
  • ·A previous owner has fitted a chain to the front door on top of the multipoint — a sign they never trusted the lock.
  • ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
  • ·The escutcheon on the front door is loose and rotates as the key turns.
  • ·The front door threshold weather-bar seal is missing its rubber blade and the metal channel is bent.
  • ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
  • ·The escutcheon plate on the back door hides a botched cylinder swap where the follower is worn.
  • ·The georgian bar between panes on one unit has slipped off its top spacer and is sitting diagonally inside the sealed cavity.

Why residents are booking composite doors right now

  • ·The resident is fitting a home cinema in the front room and needs the windows to be a full acoustic upgrade, not a nominal one.
  • ·The buyer wants the sound of the sea audible but the wind noise gone.
  • ·The buyer is moving in with two dogs and needs a back door that will not degrade with claw scrape.
  • ·The buyer wants the whole job done by one team who own the outcome — not designed in one place and fitted in another.
  • ·The homeowner is preparing the property for a smart-home installation and wants sensor pockets designed into the reveals.
  • ·The homeowner is expecting a Grandchild to stay for extended visits and wants the guest room genuinely warm overnight.
  • ·The owner wants the job to finish clean — no leftover offcuts in the skip on the drive, no sealant on the render.
  • ·There is a downstairs shower being fitted and the bathroom window needs to be swappable before the tiler starts.
  • ·The homeowner is planning a loft conversion next year and wants the windows sorted before scaffold cost is priced.
  • ·The homeowner has an infrared thermometer and has been point-checking the frames — they want the readings up by ten degrees.
  • ·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 homeowner is done with the whistle the front door letterplate makes in a north wind.
  • ·The resident has been quoted for solar and does not want the roof work to happen before the windows do.
  • ·The homeowner wants the composite slab to be paintable without voiding the manufacturer warranty.
  • ·The owner wants the master bedroom quiet enough for a night-shift partner to sleep past 11am.
  • ·The homeowner has quotes for a new kitchen next spring and wants the patio doors in before those trades arrive.

How our fitters actually do the work

  • ·The head of the frame is packed dry before the sides are fixed, so the frame does not distort during installation.
  • ·The gasket wedges are trimmed with a fresh knife blade for every unit — a dull blade tears the EPDM.
  • ·We de-glaze into a padded rack, not straight into the skip — the intact panes go to a glazier for reuse.
  • ·The van carries a set of dust extraction attachments and uses them on any grinder work in occupied rooms.
  • ·The client is walked through the finished job with a printed operation card, not a rushed verbal handover.
  • ·The threshold ramp on an accessible door is set to a maximum 15mm rise, checked with a spirit-level lip.
  • ·Fixings are always at the reinforcement points — a screw through the chamber alone loosens within a year.
  • ·The composite slab is not trimmed on site — if it doesn't fit, a new slab is ordered rather than reduced.
  • ·The internal trim goes on with pin nails through the flange, not straight through the visible face.
  • ·The lead fitter leaves a handwritten note of anything the client should watch in the first month, not a printed generic checklist.
  • ·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 internal make-good caulk is polymer, tooled with a wet finger and then a spatula for a final radius.
  • ·The door hinges are set with the correct rise before the frame is finally fixed — retro-adjustment on cheap hinges is limited.
  • ·The concrete cill under the frame is checked for cracks; a hairline gets a slurry fix before the frame is set.
  • ·The trickle vent chamber inside the frame is proven clear with a torch before the outer cap goes on.
  • ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
