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.
Why residents are enquiring right now
- ·The homeowner is selling within eighteen months and wants the front elevation to photograph well for the listing.
- ·The resident wants the noise of the school run down and the light from the morning sun up.
- ·The owner wants the front door hardware to match a specific interior palette — brass, matt black, or brushed nickel.
- ·The resident wants the whole property warm to bare feet on a January morning — the frames are the last variable.
- ·The resident wants the front door to sound solid when it closes — a hollow slap does not read as secure.
- ·The resident wants the front to look distinct on a street of five identical houses.
- ·The current front door leaks visibly around the letterplate every time the wind swings east.
- ·The resident wants an installer who will honestly say when a repair beats a replacement.

- ·The owner has tried draught-excluder tape and a chimney balloon and now accepts the frames themselves are the cause.
- ·The homeowner has quotes from two national companies and wants a local one to be honest about the same job.
- ·The resident is done with condensation-driven mould at the sill line every February.
- ·The homeowner wants a warranty they can pass on to the next owner without a fee or a form.
- ·The owner just remortgaged and wants the money to be visible on the elevation for the next valuation.

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.

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. 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.
