Fitting full-house replacement to a period stone cottage in CF10
Quoting full-house replacement on a period stone cottage means walking the reveals, not just measuring the openings. Sealant perimeter takes low-modulus polymer to accommodate seasonal stone movement. In Cardiff, that walk usually catches heritage-friendly frame profiles in conservation streets as a paired issue on the same elevation. South-facing seafront elevations fade dark PVC foil visibly within 8–10 years; lighter foils hold their colour twice as long. Estate roof pitches shed water clear of the head of the frame — lead flashing renewal is rarely required. Slate roofs above the front elevation shed water tight to the frame head; a lead flashing detail rarely needs replacement, just re-dressing. Original bay leaded-light casements are worth an offer — restorers pay reasonable money for intact panels rather than skip them. Whole property reset to A-rated thermal performance for a 20-year horizon. 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. Sash cord pulleys behind the timber lining come out clean if the paint layers haven't fused them to the box. Wind-driven rain finds sealant gaps that inland elevations tolerate — bead depth matters more than usual.
What makes a period stone cottage its own thing
- solid stone walls, often 500mm+ thick with no cavity
- irregular reveal shapes because the stone was dressed by hand
- low door and window heads — original occupants were shorter
- steeply pitched slate or tile roof with tight eaves
Our full-house replacement spec for a period stone cottage
Period cottage whole-property jobs run 3–5 days because every opening is a bespoke scribe. We survey each reveal individually and hold the quote line-by-line rather than package by count. In Cardiff we see this on the Edwardian and Victorian bay-fronted houses in Cathays and Roath, 1930s semis in Llanishen, modern builds in Pontprennau around Cyncoed, Llanishen, Roath, usually paired with heritage-friendly frame profiles in conservation streets; traffic noise on the A48 ring; single-glazed bays losing heat in tall Victorian rooms on the same elevation. 10 miles from base, A470 the whole way — Cardiff installs run as smoothly as our home patch. Council area is Cardiff Council in South Glamorgan; commercial neighbours include Cardiff Bay, Capital Business Park and the Llanishen industrial belt. Nearby: Penarth 4mi, Caerphilly 7mi, Barry 9mi. Local vibe: capital city — everything from Edwardian conservation-area bays to glass-fronted Bay apartments.
Planning & permissions
Period cottages are often listed or within conservation areas; frame style and colour are usually strictly controlled, and casement flush-sash is the default.
Locally in Cardiff, Cardiff Council covers this area. Capital city — everything from Edwardian conservation-area bays to glass-fronted Bay apartments. We check any conservation or Article 4 status against the address before quoting rather than after.
Who's asking
Owner-occupiers who bought the cottage for the character, and holiday-let operators upgrading thermally without losing period features.
In Cardiff specifically that reads as city professionals, young families in the suburbs, landlords with HMOs near Cathays Park. The recurring driver for a full-house replacement enquiry is: Owners who need modern thermal performance without visibly modernising the elevation.

What we typically find on survey
- ·The composite front door skin has a shallow dent from a delivery bike handlebar and it has ovalised the door.
- ·A previous fitter left the transport wedges in the frame corners and the internal seal never fully reset.
- ·The glazing spacer bars are aluminium, not warm-edge — a decade behind current U-value expectation.
- ·The top hinge on the front door has torn its middle screw out and been left to run on two fixings.
- ·There is a permanent green algal streak below the sill where water is bypassing the drip groove.
- ·The trickle vents are painted shut and the room fugs up within an hour of the kettle going on.
- ·The multipoint lock still throws but the internal handle has 40° of dead travel before engaging.
- ·The Yale night-latch on top of the multipoint is a sign the resident does not trust the primary lock.
- ·The letterbox opening is not draught-proofed at all — a candle held two feet away flickers in a light wind.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
- ·The reinforcement steel inside the top rail of a wide sash has rusted through in one corner.
- ·The glazing spacers between panes carry the visible desiccant snowfall that gives away a blown unit.
- ·A previous cylinder swap left the escutcheon plate rotating freely — a snap risk that nobody logged.
- ·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
- ·The catch keep for the bathroom window has been packed out with a folded matchbox to make the sash lock.
- ·The friction hinge on one window sticks at 45° open and needs the palm of a hand to nudge past.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·The porch canopy has been leaking directly onto the top of the door for years — the top edge of the slab is soft.
- ·Two units have the classic dust ring inside the sealed gap, meaning the perimeter seal has been breached for at least a year.
- ·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 seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·Condensation runs down the inside of every north-facing pane between October and March.
- ·The multipoint deadbolt still throws but the top hook has stopped catching and no one has noticed for months.
Why residents are enquiring right now
- ·The resident wants the kitchen brighter in the mornings without losing the privacy from next door's back garden.
- ·The homeowner is preparing to work from home permanently and wants the office quieter than the living room used to be.
- ·The resident does not want to be sold to — they want a survey, a written figure, and to be left to decide.
- ·The owner has watched the bay corner posts sag for a decade and now wants them straight and structural.
- ·The homeowner wants the composite front door to survive a decade of coastal salt without going chalky.
- ·The homeowner wants matt black hardware because everything inside the house is matt black — no chrome to argue with.
- ·The resident is on a listed street and wants a front door that will pass Article 4 first time.
- ·The resident wants the ground-floor windows to be genuinely secure — laminated inner pane, PAS24 hardware, real not marketed.
- ·The resident is expecting an elderly parent to move in and needs a door that opens without a shove.
- ·The owner wants the front door to feel expensive to close — the weight, the sound, the drop of the latch.
- ·The resident wants the whole property warm to bare feet on a January morning — the frames are the last variable.
- ·The homeowner is 68 and wants a threshold that will still be usable in ten years without a step.
- ·The owner is done paying to service failing 90s uPVC every couple of years and wants the whole set replaced together.
- ·The current front door leaks visibly around the letterplate every time the wind swings east.
- ·The resident wants the front to look distinct on a street of five identical houses.
- ·The owner wants the frames to disappear visually and let the view do the work.
- ·The resident works from home and wants the neighbour's dog to stop being the loudest thing on every call.
- ·The resident has been quoted for solar and does not want the roof work to happen before the windows do.
- ·The owner is done with the sliding door drag and wants one that closes with a single push.
- ·The owner just remortgaged and wants the money to be visible on the elevation for the next valuation.
- ·The homeowner is targeting a specific EPC band ahead of a rental switch and needs the frames to contribute measurably.
- ·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 wants the crew to remove and re-hang the internal curtains as part of the job, not leave that step to them.
- ·The buyer wants a specific coloured composite front door because they saw it three doors down and it made the street.
How we actually fit it
- ·The bead-in tools are rubber-faced, not steel — a steel tool marks the profile within minutes.
- ·The reveal is brushed down and vacuumed before any sealant runs, so the bead adheres to substrate, not dust.
- ·The mitre joins on any Georgian bar are picked to face the corner that is least visible from indoors.
- ·The screws through the outer frame go into pilot-drilled masonry, not driven with hammer action alone.
- ·The friction stay on a new casement is set to the client's preferred restraint at handover — 45°, 90°, or fully open.
- ·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
- ·The manufacturer's kite mark on the corner of the glass is left in place at handover — proof of spec for the next owner.
- ·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 friction stay screws are torque-limited, not driven at full trigger — over-driven screws strip the stay chamber.
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The composite door slab is inspected under torchlight for delamination before the hinges are fitted.
- ·The threshold is bedded on butyl mastic under the outer skin, giving the fitter a second waterproof line behind the perimeter silicone.
- ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
- ·The frame perimeter is checked with a smoke pencil for airtightness before the internal trims go on.
- ·Any dropped hinges on the existing door are noted before the swap so the new frame is set for the correct drop.
- ·The bay-corner post is set with a laser level across both faces before the outer frames are trimmed to fit.
- ·The window boards are pre-treated on the underside with a moisture seal before setting in place.
- ·The frame is plumbed on two axes before the first fixing goes in — not one axis and then trusted.
- ·The keys are handed to the client only after the lock has been thrown four times in and out from both sides.
- ·The frame drainage caps are proven flowing before the beading goes in — a bottle of water down the outer chamber.
- ·The frame reinforcement steel is confirmed by knock-test before selecting the fixing pattern.
- ·The bay-corner post gets a structural bracket into masonry, not a token fixing into the outer frame.
- ·The frame is protected with a low-tack tape at any point a tool might scrape it during the fitting hour.
- ·The gasket wedges are trimmed with a fresh knife blade for every unit — a dull blade tears the EPDM.

Summary — full-house replacement on a period stone cottage in Cardiff
Next step for a period stone cottage full-house replacement figure in Cardiff is a 30-minute survey — we walk every opening, check the reveal detail, and write pricing the same day. Original Crittall frames still exist on some ex-council properties — check the perimeter for lead-paint before disturbing. Original stone reveals need a resin anchor rather than plug-and-screw — the dressed face crumbles under mechanical fixings. Estate roads loop back to themselves — the crew's van sits in one spot all day without moving. Coastal render is often painted in bright colours that mask sealant discolouration — colour matching at the frame perimeter matters. Bay ceiling boxing hides century-old cabling; we test before drilling through the head of the frame. Terrace kerbs are usually granite and unforgiving — the crew boards from the van to the door to protect finished doors.
