Caerphilly Victorian terrace full-house replacement — Rosac survey & install
Anyone searching for period-appropriate glazing that won't fail Article 4 or conservation checks. That's the search intent behind most Victorian terrace enquiries for full-house replacement out of Caerphilly. We stage a full-house Victorian job around one team, front to back: front elevation on day one (kerbside window fixed), gable ends day two, rear projection last. Skip stays off the highway; the terrace can't take one for more than 24 hours without a permit. Salt spray in high winds reaches inland elevations at coastal properties — we spec stainless furniture on rear frames too. Original patio door tracks sit direct on the floor slab — we lift, level and re-set on stainless packers. Rear outshut kitchens often have flat felt roofs at 2.1m — glass and frame heights are set to clear the eaves. The two-storey bay carries loading from the roof valley — reinforced steel corner cores accept it without deflection. External foil cills are colour-matched to the frame — replace as a set or the elevation reads two-tone. Gable-end glass panes are often 2.4m+ tall; we deliver on a dedicated glass lift rather than by hand. Listed status is documented on the deed pack — we check before quoting anything other than like-for-like heritage spec. Foil colour choice on a semi is a shared question with the neighbour; matched pairs read cleaner than solo swaps. Concrete cills on post-war stock are cast into the wall; the frame sits on them without needing timber packers.

Planning & permissions
Many Victorian terraces sit inside conservation areas — colour and glazing bar profile are usually restricted to sympathetic period options.
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 georgian bar between panes on one unit has slipped off its top spacer and is sitting diagonally inside the sealed cavity.
- ·The old aluminium sliding door has grit in the track that has worn the roller wheels to elliptical.
- ·The trickle vent on the master bedroom has been foil-taped shut for warmth — condensation has doubled since.
- ·The middle mullion sags visibly across the top rail on any window wider than 1.6m.
- ·The cill drainage caps on a north-facing elevation are frozen in place with layered moss.
- ·The bottom track on the sliding door has a build-up of grit that the rollers grind through every open cycle.
- ·A previous cylinder swap left the escutcheon plate rotating freely — a snap risk that nobody logged.
- ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
- ·The top vent has been kept permanently closed with a wooden shim wedged inside the frame.
- ·The old timber sub-frame under the current uPVC unit is still in place and is soft at the bottom left corner.
- ·Every kitchen window handle has been replaced twice in ten years — a sign the espag is going, not just the handle.
- ·The internal beads pop out with a chisel and a tap, but the external glazing gasket is bonded solidly to the frame.
- ·The bathroom obscure glass pattern has been discontinued for over a decade — matching a single pane is not possible.
- ·A previous fitter left the transport wedges in the frame corners and the internal seal never fully reset.
- ·The porch-roof lead flashing has been dropping water onto the head of the front door for years.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·The letter plate cover has snapped off and the exposed brush strip has flattened over the years.
- ·The frame drainage slots at the bottom are clogged with debris, so rainwater sits inside the chamber.
- ·The gasket join at the bottom corner has separated by a few millimetres — that's where the draught is coming from.
- ·The friction hinge on one window sticks at 45° open and needs the palm of a hand to nudge past.
- ·The escutcheon on the front door is loose and rotates as the key turns.
- ·The stay arm on the top vent has bent and no longer sits into its rest bracket cleanly.
- ·The hinges are all dropped one notch from level, taking the sash out of square against the outer frame.
- ·The frame colour has gone chalky on the sun side and stayed factory white on the shaded elevation.
Why residents are enquiring right now
- ·The owner wants the frames to disappear visually and let the view do the work.

- ·The resident wants the front to look distinct on a street of five identical houses.
- ·The buyer wants a survey that says no to things when they don't fit, not just yes to everything they ask for.

- ·The buyer wants the whole job done by one team who own the outcome — not designed in one place and fitted in another.
- ·The homeowner wants the composite front door to survive a decade of coastal salt without going chalky.
- ·The buyer wants a composite front door that reads more house-proud than the run of identical rentals on the road.
- ·The current front door leaks visibly around the letterplate every time the wind swings east.

- ·There is a downstairs shower being fitted and the bathroom window needs to be swappable before the tiler starts.

How we actually fit it
- ·The composite slab is not cut on site — if it does not fit, a new slab is ordered rather than trimmed.
- ·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 old frame is removed by cutting the corners with a reciprocating saw rather than a lever bar that damages the reveal.
- ·The frame is protected with a low-tack tape at any point a tool might scrape it during the fitting hour.
- ·The old cylinder is disposed of by the crew, not left in a bag on the drive for the client to bin.
- ·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
- ·The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The trickle-vent covers are set with their vane orientation matched across a bank of windows for visual consistency.
- ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
- ·The old keys are collected and destroyed, not left in a bag on the drive.
- ·The lock cylinder is measured to sit flush with the escutcheon plate — a proud cylinder is a snap risk.
- ·Every silicone bead is tooled with the correct radius spatula, not smoothed with a wet finger only.
- ·Cylinders come out of the box, get numbered, and are the last thing fitted, so a lost cylinder does not stall the day.
- ·The gasket at the corner mitre is butt-jointed with a fresh knife cut, not stretched and hoped.
- ·The internal make-good caulk is polymer, tooled with a wet finger and then a spatula for a final radius.
- ·The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
- ·Cavity closers get inserted where the old frame's cavity closer has failed — not omitted because it is unseen work.
- ·The perimeter foam goes in in two passes so the second lift meets the first without a void in the middle.
- ·The gasket wedges are trimmed with a fresh knife blade for every unit — a dull blade tears the EPDM.
- ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
- ·The client is walked through the operation of every lock, every vent, and every restraint before the crew leaves.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.

Summary — full-house replacement on a Victorian terrace in Caerphilly
A Victorian terrace full-house replacement install in Caerphilly is a walk-and-quote job — no assumptions from the road. Whole property reset to A-rated thermal performance for a 20-year horizon on this property type. 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. The load path through the bay corner post pulls diagonally when the roof sags; reinforced steel accepts it, aluminium alone deflects. Gravel front gardens mean the crew boards from the van to the elevation to avoid tracking stones inside. External timber cladding at the head of the window is easily matched to modern PVC trim in a coordinated foil. Developer window frames are typically low-spec multi-chamber uPVC — the profile is fine, the hinges and glass are the fail point.
