Fitting composite doors to a 1960s new-town house in CF83
A 1960s new-town house in Caerphilly isn't the same brief as a standard modern estate home — even when both need composite doors. Timber-frame or system-build construction (varies by phase) and generous glazing area — original spec used single-glazed sliding aluminium between them decide what the frame can be, before service selection even starts. We work these across CF83 on a regular A468 route out of the Caerphilly yard. Brick reveals absorb sealant unevenly; we prime the arris with SBR before the perimeter bead runs. Original conversion sealant is often silicone that has failed at the perimeter; we strip and re-run at every swap. Original Crittall frames still exist on some ex-council properties — check the perimeter for lead-paint before disturbing. Oil-heating running costs make triple-glazing an easier upsell on barn conversions than on urban stock. Render around the frame edge is often 60s scratch-coat — patch and re-paint the same visit rather than mask. The porch canopy fixings are usually one bolt into masonry and one into the fascia — we test both before removing the old door. Chimney breasts eat a foot of internal width on both sides — bay window quotes account for it in the survey. South-facing seafront elevations fade dark PVC foil visibly within 8–10 years; lighter foils hold their colour twice as long. Estate roof pitches shed water clear of the head of the frame — lead flashing renewal is rarely required.
Planning & permissions
New-town estates are rarely restricted at the front-door level, though large glazing swaps sometimes need building regs sign-off for structural loading.
Locally in Caerphilly, Caerphilly County Borough Council covers this area. Market town with the castle as the centrepiece — a mix of stone period stock and modern estates. We check any conservation or Article 4 status against the address before quoting rather than after.
Who's asking
Second-time buyers upgrading original new-town glazing, and long-time owners doing full-property refurbs for retirement.
In Caerphilly specifically that reads as young families upgrading first homes, long-time owners replacing original 90s uPVC. The recurring driver for a composite doors enquiry is: Owners solving the cold-bridge draught complaint that defines original new-town spec.

Our composite doors spec for a 1960s new-town house
New-town front doors sit in wide, shallow porches. A modern composite in a bold colour reads well against the pale render — Chartwell and Anthracite are the buyer defaults. In Caerphilly we see this on the stone-fronted terraces, post-war semis around the castle and newer estates out toward Bedwas around Bedwas, Trethomas, Machen, usually paired with wind-driven rain off the mountain ridge; noise from the A469 corridor; tired 1990s-era double glazing failing at the seals on the same elevation. Easy in via the A469, and we're 10 minutes from the A470 for vans loaded with full-house glass. Council area is Caerphilly County Borough Council in Mid Glamorgan; commercial neighbours include Pontygwindy Industrial Estate and Bedwas House Industrial Estate. Nearby: Cardiff 7mi, Newport 11mi, Pontypridd 10mi. Local vibe: market town with the castle as the centrepiece — a mix of stone period stock and modern estates.
What we typically find on survey
- ·The escutcheon plate on the back door hides a botched cylinder swap where the follower is worn.
- ·One sash locks by lifting a nail out of the frame — a bodge from a decade ago that everyone forgot about.
- ·The Yale night-latch on top of the multipoint is a sign the resident does not trust the primary lock.
- ·The bottom track on the sliding door has a build-up of grit that the rollers grind through every open cycle.
- ·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
- ·The bottom hinge on the front door has torn its top screw fixing free of the frame.
- ·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.
- ·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
- ·The internal beadwork has been painted so many times the mitres are unrecognisable.
- ·The composite door slab has a hairline crack along the letterplate cut-out from a delivery boot.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·One casement's friction stay has been swapped for a random spare that doesn't match the arm geometry.
- ·The internal locking cams on the multipoint have been ground down by a mismatched keep pattern.
- ·Every south-facing frame has visible micro-cracking in the surface film — early sign of UV embrittlement.
- ·The cill drainage caps on a north-facing elevation are frozen in place with layered moss.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.

- ·The trickle-vent covers have been snapped off and taped over from inside.
- ·Original security bolts on the ground floor sashes are seized in place and no longer key-lockable.
- ·The old aluminium sliding door has a cracked head roller that pulls the door out of parallel with the frame.
- ·A previous decorator's dust sheet was left inside the frame chamber during a repaint and is still there.
- ·The top hinge on the front door has torn its middle screw out and been left to run on two fixings.
- ·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 enquiring right now
- ·The homeowner has an infrared thermometer and has been point-checking the frames — they want the readings up by ten degrees.
- ·There is a downstairs shower being fitted and the bathroom window needs to be swappable before the tiler starts.

- ·The homeowner is on a smart meter and can see the room-by-room heat loss on a phone app.
- ·The buyer wants a full set of the same colour across every elevation, not the current mixed collection.

- ·The owner wants the job to finish clean — no leftover offcuts in the skip on the drive, no sealant on the render.

- ·The wife wants the noise from the trunk road down; the husband wants the heating bill down; both are on the enquiry.

- ·The buyer wants the whole ground floor to feel more connected to the garden without losing the wall.
- ·The resident works from home and wants the neighbour's dog to stop being the loudest thing on every call.
- ·The owner has tried draught-excluder tape and a chimney balloon and now accepts the frames themselves are the cause.
- ·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 resident cycles to work and wants a bike-in-porch design that a survey needs to plan around.
How we actually fit it
- ·The internal trim goes on with pin nails through the flange, not straight through the visible face.
- ·The composite slab is not cut on site — if it does not fit, a new slab is ordered rather than trimmed.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.
- ·The old broken glass is bagged in a labelled sack, not tipped loose into a general skip.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The frame square is checked at the diagonals before any glass goes in — a square frame stays square.
- ·The internal cill is scribed to the reveal, not just butted and caulked over the gap.
- ·The bay-corner post is set with a laser level across both faces before the outer frames are trimmed to fit.
- ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
- ·The mitre joins on any Georgian bar are picked to face the corner that is least visible from indoors.
- ·The glass has a factory kite mark visible at handover — not scraped off by a lazy cleaner during the fitting hour.
- ·The frame reinforcing steel is confirmed inside the top rail before the transom fixing is chosen.
- ·The install date is stamped inside the frame chamber for future reference — a decade later a client can still date it.
- ·The letterplate is fitted with the internal flap set to close under its own weight without dragging.
- ·The internal architrave is coped rather than mitred where the reveal wall is out of true.
- ·The frame perimeter is checked with a smoke pencil for airtightness before the internal trims go on.
- ·The trickle vent chamber inside the frame is proven clear with a torch before the outer cap goes on.
- ·The keeps for the multipoint are set with a strike plate template, not marked by eye against the closed door.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.
- ·The crew photographs the finished elevation from the street and shares it with the office as the sign-off record.
- ·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 old cylinder is disposed of by the crew, not left in a bag on the drive for the client to bin.
- ·Cylinders come out of the box, get numbered, and are the last thing fitted, so a lost cylinder does not stall the day.

Summary — composite doors on a 1960s new-town house in Caerphilly
1960s new-town house jobs in Caerphilly get a named contact from survey to snag. 10-year product guarantee with a 2-year fitting guarantee on top sits behind it. Wind-driven rain finds sealant gaps that inland elevations tolerate — bead depth matters more than usual. Sash cord pulleys behind the timber lining come out clean if the paint layers haven't fused them to the box. Slate roofs shed water tight to the head of the frame; lead flashing detail is usually original and only needs re-dressing. Original Crittall steel casements can be recycled at scrap — worth calling ahead if the client wants the fee. Ex-council reveal openings are generous — swapping to a slimmer profile actually loses daylight, not gains it. Soft verges take van weight for a few hours in dry weather; we stage deliveries around forecast rain.
