Full-house replacement for 1960s new-town homes across Caerphilly
A 1960s new-town house in Caerphilly isn't the same brief as a standard modern estate home — even when both need full-house replacement. 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. Original oak lintels can be scored and treated, not replaced, when they sit sound above a new frame. Hardware fails on schedule at year 8–10; upgrading hinges alone during a full re-glaze extends the frame life a decade. Cavity insulation was retrofit-installed on most 30s semis in the 2010s — check for bead migration at the head before the new frame lands. External foil cills are colour-matched to the frame — replace as a set or the elevation reads two-tone. The two-storey bay carries loading from the roof valley — reinforced steel corner cores accept it without deflection. Listed status is documented on the deed pack — we check before quoting anything other than like-for-like heritage spec. Gable-end glass panes are often 2.4m+ tall; we deliver on a dedicated glass lift rather than by hand. Concrete cills on post-war stock are cast into the wall; the frame sits on them without needing timber packers. Foil colour choice on a semi is a shared question with the neighbour; matched pairs read cleaner than solo swaps.
What makes a 1960s new-town house its own thing
- timber-frame or system-build construction (varies by phase)
- flat or shallow-pitch roof with a mono-pitch garage or car port
- consistent street layout with wide grass verges
- generous glazing area — original spec used single-glazed sliding aluminium
Our full-house replacement spec for a 1960s new-town house
New-town whole-property jobs go quick — reveals are consistent, layout is walkable, estate roads are van-friendly. Typically 2–3 days with the patio door and front door swapped on the same visit. 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.

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.
What we typically find on survey
- ·The letter plate cover has snapped off and the exposed brush strip has flattened over the years.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
- ·The bottom track on the sliding door has a build-up of grit that the rollers grind through every open cycle.
- ·The internal beadwork has been painted so many times the mitres are unrecognisable.
- ·One patio-door interlock has a bent alignment lug — the door jams shut half of the time.
- ·The trickle-vent covers have been snapped off and taped over from inside.
- ·The multipoint keeps have worn a shallow groove where the hooks now catch — closing needs a lift-and-pull.
- ·The middle mullion sags visibly across the top rail on any window wider than 1.6m.
- ·The window boards inside are chipboard, swollen at the edges from years of trickle condensation.
- ·The georgian bar between panes on one unit has slipped off its top spacer and is sitting diagonally inside the sealed cavity.
- ·The internal locking cams on the multipoint have been ground down by a mismatched keep pattern.
- ·The escutcheon plate on the back door hides a botched cylinder swap where the follower is worn.
- ·Original security stickers from the installer are still on the bottom of the panes, twenty years later.
- ·The gap under the front door has been carpet-strip filled from inside — the exterior weather bar is missing.
- ·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.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·The trickle-vent screw covers are missing and the internal chamber has filled with cobweb.
- ·The bottom hinge on the front door has torn its top screw fixing free of the frame.
- ·One sash locks by lifting a nail out of the frame — a bodge from a decade ago that everyone forgot about.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
- ·The bathroom pane is patterned glass from the original build, and the pattern is no longer a current stock line.
- ·The internal reveal plaster is spalling under the cill where condensation has run for years.
- ·Every south-facing frame has visible micro-cracking in the surface film — early sign of UV embrittlement.
- ·The reinforcement steel inside the top rail of a wide sash has rusted through in one corner.
- ·A cat flap has been cut through the lower panel of the back door, weakening the panel and voiding warranty.
- ·There is no drip groove on the underside of the cill — water tracks straight back onto the brick face.
- ·A tenant repair on the bathroom window has used bathroom silicone as the primary bead — it's already gone black.
- ·The escutcheon on the front door is loose and rotates as the key turns.
- ·A weep vent that was factory-drilled has been over-painted three times and no longer clears water from the chamber.

- ·The owner wants the front door to feel expensive to close — the weight, the sound, the drop of the latch.
How we actually fit it
- ·The perimeter airtight tape is applied over the frame flange in a single unbroken run around all four sides.
- ·The crew takes the old glass off site in a labelled sack that day, not a skip left on the drive.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The mitre joins on any Georgian bar are picked to face the corner that is least visible from indoors.
- ·Ground protection sheet goes down before the old frame comes out — not after the mess starts.
- ·The multipoint hooks are lightly greased after fitting, before the door is closed for the first time.
- ·The crew asks the client where the kettle lives before they set up so tea gets made rather than negotiated.
- ·Fixings are set at the manufacturer's spacing, not evenly spaced by eye — the corner loads matter.
- ·The crew photographs the finished elevation from the street and shares it with the office as the sign-off record.
- ·The perimeter foam goes in in two passes so the second lift meets the first without a void in the middle.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.
- ·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 reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
- ·The gasket at the corner mitre is butt-jointed with a fresh knife cut, not stretched and hoped.
- ·The client is left with the manufacturer's paperwork in a labelled envelope, not a folded receipt tucked inside a drawer.
- ·The threshold sealant runs the full width with a single tool pass, not stitched together in inches.
- ·The frame drainage caps are proven flowing before the beading goes in — a bottle of water down the outer chamber.
- ·The internal architrave is scored along its length with a fresh blade before removal, so the wallpaper does not tear back.
- ·The glazing bead is tapped in with a rubber mallet, not a metal claw — the profile marks otherwise.
- ·The internal cill is scribed to the reveal, not just butted and caulked over the gap.
- ·The keys are handed to the client only after the lock has been thrown four times in and out from both sides.
- ·The door hinges are set with the correct rise before the frame is finally fixed — retro-adjustment on cheap hinges is limited.
- ·The old handles are offered to the client before being binned — sometimes a chrome D-handle finds a shed door life.
- ·The screws through the outer frame go into pilot-drilled masonry, not driven with hammer action alone.
- ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
- ·The keeps for the multipoint are set with the door open and the position marked, not adjusted by eye once the door is closed.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
- ·The reveal is brushed down and vacuumed before any sealant runs, so the bead adheres to substrate, not dust.
- ·The multipoint keeps get a smear of grease inside the pocket before the door is closed for the first time.
- ·Cylinders come out of the box, get numbered, and are the last thing fitted, so a lost cylinder does not stall the day.
Owner occupiers doing the whole property in one go
Owner occupiers doing the whole property in one go around Caerphilly: what changes
The reader here has decided the whole property needs doing and is now comparing installers rather than products. That means the useful information is programme length, who is actually on site, and what the written quote covers opening by opening.
What matters most on this kind of job
- One survey covering every opening, measured and photographed
- An itemised written price so single openings can be added or dropped
- The site tidy happens twice per day, not once at the end, so brick dust doesn't track through the house.
- The threshold is bedded on butyl mastic under the outer skin, giving the fitter a second waterproof line behind the perimeter silicone.

Questions we get on 1960s new-town homes jobs like this
How long does a full-house replacement job take on a 1960s new-town homes?+
Typically 2–4 days depending on count, with a final snag visit a week later is typical. On this property type the extra time usually goes into original 60s sliding aluminium frames cold-bridge and ice up internally, which we allow for at survey rather than discovering it on fitting day.
What do you check at survey on a 1960s new-town homes?+
Timber-frame walls mean the frame fixes to studs, not to masonry — survey before ordering long fixings We also sight the openings for square, check the cill detail and confirm access, because getting a van and glass onto the street matters here: easy in via the A469, and we're 10 minutes from the A470 for vans loaded with full-house glass.
Is it worth upgrading the whole elevation rather than one opening?+
On a 1960s new-town homes it often is, because the frames were fitted at the same time and tend to fail together. Owners solving the cold-bridge draught complaint that defines original new-town spec. We price both options so you can compare them properly.
Do you fit full-house replacement on 1960s new-town homes around Caerphilly?+
Regularly. Bedwas, CF83 is where most of this work lands, and we also cover Cardiff, Newport, Pontypridd. Easy in via the A469, and we're 10 minutes from the A470 for vans loaded with full-house glass.
Do I have to use the same specification in every room?+
No, and it is usually cheaper not to. Triple glazing where noise or cold is the real complaint, A rated double elsewhere, obscure glass in bathrooms. We price the options side by side at survey.
Can I stage a whole house replacement over two visits?+
Yes. Front elevation and front door first, rear later is a common split. It costs slightly more overall than doing everything in one visit and we will show you the difference in writing before you decide.
