Caerphilly ex-council semi full-house replacement — Rosac survey & install
Right-to-buy long-time owners, and second-owner buyers refurbishing the plot for its garden size. That's the mix reaching out for full-house replacement in Caerphilly on this property type — often as part of a wider refresh, sometimes as a like-for-like fix. Ex-council semis are a straightforward whole-property job — square openings, forgiving reveals, off-street parking for the van. Typically 2 days on-site with a snag visit a week later. Terrace kerbs are usually granite and unforgiving — the crew boards from the van to the door to protect finished doors. Bay ceiling boxing hides century-old cabling; we test before drilling through the head of the frame. Coastal render is often painted in bright colours that mask sealant discolouration — colour matching at the frame perimeter matters. Stone walls hold thermal mass but radiate cold at the reveal edge; deep frames pull the cold plane further from the room. Stained-glass fanlights above the door can be re-set into a modern composite slab if intact, giving continuity across the swap. New-build reveals are square to within 3mm — packing is minimal and the frame lands true first time. Roof canopies are usually mono-pitch and shallow — scaffold clearance rarely exceeds 2.1m above the frame head. Sash pockets in the original box are often stuffed with newspaper insulation — worth checking dates for interest but binning safely. Cavity insulation was retrofit-installed on most 30s semis in the 2010s — check for bead migration at the head before the new frame lands.
Common ex-council semis problems we quote full-house replacement for
- 1Original Crittall or 70s aluminium replaced with 90s-spec uPVC that's now failing at the gaskets.
- 2Front door reveal has been enlarged and re-worked over the decades, sometimes badly.
- 3Render around the frame perimeter is powdery and needs sealing before the new frame lands.
Planning & permissions
Ex-council stock is rarely restricted; owners have free reign over colour and style. Many streets end up with a full mix of finishes as owners upgrade individually.
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
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
- ·The old aluminium sliding door has grit in the track that has worn the roller wheels to elliptical.
- ·Original door furniture is 90s brass, tarnished, and no longer matches anything else on the elevation.
- ·Every kitchen window handle has been replaced twice in ten years — a sign the espag is going, not just the handle.
- ·The trickle-vent screw covers are missing and the internal chamber has filled with cobweb.
- ·The escutcheon on the front door is loose and rotates as the key turns.
- ·A previous owner has fitted a chain to the front door on top of the multipoint — a sign they never trusted the lock.
- ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
- ·The multipoint keeps have worn a shallow groove where the hooks now catch — closing needs a lift-and-pull.
- ·The bottom rail on the sash has taken years of rain runoff and swollen enough to bind on the frame.
- ·The friction hinge on one window sticks at 45° open and needs the palm of a hand to nudge past.
- ·The bathroom obscure glass pattern has been discontinued for over a decade — matching a single pane is not possible.
- ·The georgian bar between the panes has come detached from the top spacer on one unit.
- ·The trickle-vent covers have been snapped off and taped over from inside.
- ·A previous decorator's dust sheet was left inside the frame chamber during a repaint and is still there.
- ·The window boards inside are chipboard, swollen at the edges from years of trickle condensation.
- ·A weep vent that was factory-drilled has been over-painted three times and no longer clears water from the chamber.
- ·The gasket at the vent has perished and pulled away from its channel in two-inch sections.
- ·The Yale night-latch on top of the multipoint is a sign the resident does not trust the primary lock.
- ·The multipoint deadbolt still throws but the top hook has stopped catching and no one has noticed for months.
- ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
- ·The trickle vent on the master bedroom has been foil-taped shut for warmth — condensation has doubled since.
- ·The cill drainage caps on a north-facing elevation are frozen in place with layered moss.
- ·Original beads have been over-painted so many times they no longer clip flush and rattle in a gust.
- ·The frame reinforcement steel inside the outer frame has begun to rust and stain the internal white finish.
- ·Original security stickers from the installer are still on the bottom of the panes, twenty years later.
- ·The letterplate flap spring has gone slack and the flap now hangs open in a light breeze.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·One patio-door interlock has a bent alignment lug — the door jams shut half of the time.
- ·The old timber sub-frame under the current uPVC unit is still in place and is soft at the bottom left corner.
Why residents are enquiring right now

How we actually fit it
- ·Door thresholds are set with a spirit level along their full length and then re-checked with a straight edge.
- ·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.
- ·The door hinges are set with the correct rise before the frame is finally fixed — retro-adjustment on cheap hinges is limited.
- ·The frame drainage caps are proven flowing before the beading goes in — a bottle of water down the outer chamber.
- ·The crew leaves the client with a printed adjustment card so the multipoint keeps can be re-set six months on without a callout.
- ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
- ·The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·The install date is stamped inside the frame chamber for future reference — a decade later a client can still date it.
- ·The crew calls the client at 5pm the day before to confirm arrival window and site access details.
- ·The composite slab is not cut on site — if it does not fit, a new slab is ordered rather than trimmed.
- ·The internal skirting is protected with a strip of packing tape across the top edge before any tool touches it.
- ·The multipoint gearbox is thrown by hand before the frame goes in — a factory fault at that point is a five-minute fix.
- ·The client is left with the manufacturer's paperwork in a labelled envelope, not a folded receipt tucked inside a drawer.
- ·The head of the frame is packed dry before the sides are fixed, so the frame does not distort during installation.
- ·Ground protection sheet goes down before the old frame comes out — not after the mess starts.
- ·New frames sit on hardwood packers, not plastic offcuts — plastic creeps under load, timber does not.
- ·The client is walked through the operation of every lock, every vent, and every restraint before the crew leaves.
- ·The crew takes the old glass off site in a labelled sack that day, not a skip left on the drive.
- ·The old frame's fixing holes in the brick are filled and made good before the new outer frame beads up to the reveal.
- ·The client's alarm sensors on the old frames are removed and returned to the client, not binned by default.
- ·The lead fitter photographs the reveal condition before the old frame comes out and shares those photos with the office.
- ·The gasket at the corner mitre is butt-jointed with a fresh knife cut, not stretched and hoped.
- ·The frame reinforcement steel is confirmed by knock-test before selecting the fixing pattern.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
- ·The frame reinforcing steel is confirmed inside the top rail before the transom fixing is chosen.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·The frame perimeter is checked with a smoke pencil for airtightness before the internal trims go on.
- ·The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·The old frame is removed by cutting the corners with a reciprocating saw rather than a lever bar that damages the reveal.
Landlords, letting agents and portfolio owners
Buying full-house replacement as landlords, letting agents and portfolio owners
Rental property work is judged on cost per year of service, not on the day one price. This page focuses on specification that survives heavy use, and on scheduling the work inside a void window.
The things worth checking before you accept a price
- Hardware specified for heavy use rather than the cheapest available
- Documentation for the file: guarantee, insurance and compliance certificates
- The dustsheet inside the room is a heavy canvas taped to the skirting, not a light plastic left loose.
- The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
Repeat work for local landlords across multiple properties, with the same specification carried between them

Questions we get on ex-council semis jobs like this
How long does a full-house replacement job take on a ex-council semis?+
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 crittall or 70s aluminium replaced with 90s-spec upvc that's now failing at the gaskets, which we allow for at survey rather than discovering it on fitting day.
Will planning rules affect full-house replacement on this kind of property?+
Ex-council stock is rarely restricted; owners have free reign over colour and style. Many streets end up with a full mix of finishes as owners upgrade individually. We check the position with Caerphilly County Borough Council before anything is ordered so there is no surprise after manufacture.
Do full-house replacement suit a ex-council semis?+
Yes, with the right profile. On an ex-council semi means the reveal and sightlines drive the specification more than the price list does, and around Caerphilly we allow for wind-driven rain off the mountain ridge when we choose the frame and the seal.
Do you fit full-house replacement on ex-council semis 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.
Will new windows move the EPC band?+
Replacing failed or single glazed units with A rated sealed units improves the fabric score. How far the band moves depends on heating, insulation and the rest of the assessment, so we will not promise a specific letter.
What specification do you recommend for a rental?+
Heavier duty hardware, restrictors on upper floor openings, and A rated units. The extra on day one is small against the cost of repeat callouts across a tenancy.

Summary — full-house replacement on a ex-council semi in Caerphilly
Ex-council semi jobs in Caerphilly get a named contact from survey to snag. 10-year product on every frame, 2-year fitting on the whole package, single point of contact sits behind it. Where the original glazing bars were 22mm ovolo, we match printed bars to that width — not the modern 26mm default. Seafront elevations often benefit from a rain deflector bar over the composite door letter plate — standard spec here. Around Caerphilly that usually means wind-driven rain off the mountain ridge on stone-fronted terraces, post-war semis around the castle and newer estates out toward Bedwas, with Bedwas and Trethomas the streets we are on most. Soft verges take van weight for a few hours in dry weather; we stage deliveries around forecast rain. Ex-council reveal openings are generous — swapping to a slimmer profile actually loses daylight, not gains it. Original Crittall steel casements can be recycled at scrap — worth calling ahead if the client wants the fee. Slate roofs shed water tight to the head of the frame; lead flashing detail is usually original and only needs re-dressing.
