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.
Why residents are enquiring right now
- ·The homeowner is selling within eighteen months and wants the front elevation to photograph well for the listing.
- ·A newborn has arrived and the parents want the nursery to hold a stable overnight temperature.
- ·The resident wants the front to look distinct on a street of five identical houses.
- ·The buyer wants a specific coloured composite front door because they saw it three doors down and it made the street.
- ·The homeowner wants a five-star Checkatrade installer at the door, not a subcontracted crew nobody has vetted.
- ·The buyer wants the front door delivered pre-hung and pre-glazed on the same date as the frames.
- ·The owner has tried draught-excluder tape and a chimney balloon and now accepts the frames themselves are the cause.
- ·The resident wants the front door lock to be re-keyable if a set of keys goes missing in year three.
- ·The homeowner is done with the whistle the front door letterplate makes in a north wind.
- ·The buyer wants the porch to stay a porch and not turn into a mud room by function.
- ·The homeowner is planning a loft conversion next year and wants the windows sorted before scaffold cost is priced.
- ·The buyer has just moved in and is fixing everything the vendor's homebuyer report flagged, in priority order.
- ·The owner is preparing the elevation for a specific street-photo listing and wants the finish to be photographable in raking morning light.
- ·The resident does not want to be sold to — they want a survey, a written figure, and to be left to decide.
- ·The resident works from home and wants the neighbour's dog to stop being the loudest thing on every call.
- ·The homeowner has quotes for a new kitchen next spring and wants the patio doors in before those trades arrive.
- ·The owner is buying and wants to time the frame swap for the week between exchange and moving in.
- ·The homeowner wants the composite front door to survive a decade of coastal salt without going chalky.
- ·The homeowner wants the crew to catch anything the vendor's survey missed while they're on site.
- ·The buyer is running a small business from the home office and wants the kerb to say established and settled.
- ·The resident wants the ground-floor windows to be genuinely secure — laminated inner pane, PAS24 hardware, real not marketed.
- ·There is a puppy in training and the sliding door onto the garden has to work with a paw against the glass.
- ·The buyer wants the whole ground floor to feel more connected to the garden without losing the wall.
- ·The homeowner is targeting a specific EPC band ahead of a rental switch and needs the frames to contribute measurably.
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.
