Who this page is for: owner occupiers replacing one door or one window in Cwmbran
Most enquiries at this size start with one specific fault. This page covers what that fault usually turns out to be locally, what the fix costs relative to a full replacement, and when it is worth waiting and doing more openings together.
Where this job stands or falls
- A straight answer on whether the existing frame can be repaired instead
- A new unit that matches the frames already on the property
- The old handles are offered to the client before being binned — sometimes a chrome D-handle finds a shed door life.
- The concrete cill under the frame is checked for cracks; a hairline gets a slurry fix before the frame is set.

What we typically find on patio doors surveys around here
- ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
- ·The composite slab has swelled by 2mm on the hinge stile from years of morning-sun exposure.
- ·The escutcheon plate on the back door hides a botched cylinder swap where the follower is worn.
- ·Original security bolts on the ground floor sashes are seized in place and no longer key-lockable.
- ·The kitchen window has a defrost line across the low-e coating — argon gas long gone.
- ·A cat flap has been cut through the lower panel of the back door, weakening the panel and voiding warranty.
- ·The composite door slab has a hairline crack along the letterplate cut-out from a delivery boot.
- ·The multipoint keeps have worn a shallow groove where the hooks now catch — closing needs a lift-and-pull.
- ·The composite front door skin has a shallow dent from a delivery bike handlebar and it has ovalised the door.
- ·There is no drip groove on the underside of the cill — water tracks straight back onto the brick face.
- ·There is a paint bridge from the internal architrave to the frame that will crack the moment the new unit lifts out.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·There is a hairline crack running diagonally from the top corner of one bathroom pane where the frame has twisted.
- ·The internal reveal architrave has been re-fixed with panel pins that have rusted and stained the paintwork.
- ·The outer frame has moved fractionally over the years, dropping the bottom hinge screw pattern out of line.
- ·The reveal internally has been skimmed over the old plaster edge, hiding a 6mm gap behind the architrave.
Why residents are booking patio doors right now
- ·The homeowner wants a five-star Checkatrade installer at the door, not a subcontracted crew nobody has vetted.
- ·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 buyer wants a genuine step-up in security, not a marketing claim — PAS24 tested, not PAS24 marketed.
- ·The resident wants an installer who will honestly say when a repair beats a replacement.
- ·The owner wants the property to look ten years newer without needing an extension.
- ·The buyer wants an installer who will still exist to honour a guarantee in year eight.
- ·The homeowner is done with the whistle the front door letterplate makes in a north wind.
- ·The resident has already lost one composite door to a courier boot and wants the replacement rated for impact.
- ·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 the whole property warm to bare feet on a January morning — the frames are the last variable.
- ·The homeowner wants matt black hardware because everything inside the house is matt black — no chrome to argue with.
- ·The buyer wants the heating bill visibly lower before next winter, not a marginal improvement they have to guess at.
- ·The buyer wants a specific coloured composite front door because they saw it three doors down and it made the street.
- ·The buyer wants a genuine Which? Trusted Trader install, not a subcontracted crew running the badge.
- ·The homeowner wants a warranty they can pass on to the next owner without a fee or a form.
- ·The buyer wants the property to look owned rather than tenanted — the front door tells that story first.
How our fitters actually do the work
- ·The gasket is dressed into every corner with a specific gasket tool, not a screwdriver, so the corner stays sharp.
- ·The client is walked through the operation of every lock, every vent, and every restraint before the crew leaves.
- ·The composite slab is not cut on site — if it does not fit, a new slab is ordered rather than trimmed.
- ·The internal architrave is scored along its length with a fresh blade before removal, so the wallpaper does not tear back.
- ·The multipoint hooks are lightly greased after fitting, before the door is closed for the first time.
- ·The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
- ·The door slab gets a full inspection before hanging — dents, delamination, edge integrity, all noted before fixings go through.
- ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
- ·The frame reinforcing steel is confirmed inside the top rail before the transom fixing is chosen.
- ·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 client's alarm sensors on the old frames are removed and returned to the client, not binned by default.
- ·The client is left with the manufacturer's paperwork in a labelled envelope, not a folded receipt tucked inside a drawer.
- ·The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·The frame reinforcement steel is confirmed by knock-test before selecting the fixing pattern.
- ·The internal make-good uses caulk to the plaster, silicone to the tiles, and neither where paint has to go over.
- ·The internal architrave is coped rather than mitred where the reveal wall is out of true.

Faults we fix before recommending patio doors
A door that needs lifting, shoving or a second attempt to lock is warning you before the gearbox fails completely.
A sliding door that fights you is nearly always rollers and track debris, not a dead door.
Most break-ins through glazed openings exploit the cylinder or the keeps, both of which are upgradeable in an afternoon.
French doors are a pair, so the fault is usually in how the two leaves meet rather than in either leaf on its own.
