Full-house replacement for 1960s new-town homes across Cardiff
Quoting full-house replacement on a 1960s new-town house means walking the reveals, not just measuring the openings. Reveals are consistent across the estate — one survey covers most neighbouring plots. In Cardiff, that walk usually catches heritage-friendly frame profiles in conservation streets as a paired issue on the same elevation. Brick reveals absorb sealant unevenly; we prime the arris with SBR before the perimeter bead runs. Original conversion sealant is often silicone that has failed at the perimeter; we strip and re-run at every swap. 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. Whole property reset to A-rated thermal performance for a 20-year horizon. Lime plaster reacts to modern silicone with staining; we use low-modulus polymer at the perimeter instead. Wide walkways in front of the property give plenty of room for lifts and staging — no kerbside pressure. Cavity trays sit above the head of each opening at DPC height — we check the buyer pack before drilling above the frame. Pebbledash render on the upper storey chips at the frame perimeter during removal; we score-and-drop rather than lever. Coastal render is often painted in bright colours that mask sealant discolouration — colour matching at the frame perimeter matters. Estate roads loop back to themselves — the crew's van sits in one spot all day without moving.
What makes a 1960s new-town house its own thing
- timber-frame or system-build construction (varies by phase)
- consistent street layout with wide grass verges
- flat or shallow-pitch roof with a mono-pitch garage or car port
- generous glazing area — original spec used single-glazed sliding aluminium
Who's asking
Second-time buyers upgrading original new-town glazing, and long-time owners doing full-property refurbs for retirement.
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 solving the cold-bridge draught complaint that defines original new-town spec.
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 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.

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 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.
What we typically find on survey
- ·One handle turns freely through 180° with no engagement — a snapped internal cam.
- ·The internal locking cams on the multipoint have been ground down by a mismatched keep pattern.
- ·The catch keep for the bathroom window has been packed out with a folded matchbox to make the sash lock.
- ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
- ·A homemade timber threshold has been screwed to the concrete cill in front of the patio door.
- ·The manufacturer's kite mark on the corner of the glass is late-90s vintage, which explains the thermal performance.
- ·The georgian bar between the panes has come detached from the top spacer on one unit.
- ·There is a paint bridge from the internal architrave to the frame that will crack the moment the new unit lifts out.
- ·Every casement in the property opens with a firm tug on the second click — the friction stays are seized.
- ·The friction hinge on a bedroom window has one detent — it either opens fully or slams shut on any breeze.
- ·The hinges are all dropped one notch from level, taking the sash out of square against the outer frame.
- ·The cylinder on the front door still has the builder's key stamp, meaning it has never been changed since handover.
- ·The outer frame has moved fractionally over the years, dropping the bottom hinge screw pattern out of line.
- ·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
- ·Original beads have been over-painted so many times they no longer clip flush and rattle in a gust.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·The top vent has been kept permanently closed with a wooden shim wedged inside the frame.
- ·The old aluminium sliding door has a cracked head roller that pulls the door out of parallel with the frame.
- ·There is a hairline crack running diagonally from the top corner of one bathroom pane where the frame has twisted.
- ·The bay corner post has never had its structural bracket — a common corner-cutting shortcut a decade ago.
- ·A tenant repair on the bathroom window has used bathroom silicone as the primary bead — it's already gone black.
- ·The trickle vents are painted shut and the room fugs up within an hour of the kettle going on.
- ·The mid-rail on the composite door is bowed outward at the middle by 2mm — a slab-warp symptom.
- ·The door-side glazed sidelight has a shattered internal pane held together by the laminated interlayer.
- ·Handles on the ground-floor windows have been swapped for cheap replacements that no longer match the espag rod.
- ·The composite door skin has a UV bloom on the south-facing elevation that no longer matches the colour on the shaded elevation.
- ·The gap under the front door has been carpet-strip filled from inside — the exterior weather bar is missing.
- ·The trickle-vent covers have been snapped off and taped over from inside.
- ·The gasket join at the bottom corner has separated by a few millimetres — that's where the draught is coming from.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
Why residents are enquiring right now
- ·The wife wants the noise from the trunk road down; the husband wants the heating bill down; both are on the enquiry.
- ·The buyer wants a specific coloured composite front door because they saw it three doors down and it made the street.
- ·The resident has already lost one composite door to a courier boot and wants the replacement rated for impact.
- ·The resident is done with condensation-driven mould at the sill line every February.
- ·The owner wants the whole property refurbished for a big family gathering nine weeks out — everything sequenced tightly.
- ·The resident wants the noise of the school run down and the light from the morning sun up.
- ·The resident is a keen gardener and wants a patio door that opens as fully as possible into the garden.
- ·The resident does not want to be sold to — they want a survey, a written figure, and to be left to decide.
- ·The homeowner is expecting a Grandchild to stay for extended visits and wants the guest room genuinely warm overnight.
- ·The resident wants the frames to survive a specific paint colour on the render for at least a decade.
- ·The owner wants the front door to feel expensive to close — the weight, the sound, the drop of the latch.
- ·The buyer wants the frames to still look right in twenty years, not just at handover.
- ·The homeowner wants a warranty they can pass on to the next owner without a fee or a form.
- ·The resident has already had one failed installation and wants to know exactly how this one will differ.
- ·The buyer wants a survey that says no to things when they don't fit, not just yes to everything they ask for.

- ·The owner has an electric car on the drive and wants the front to say the whole property has been kept up.

- ·The owner wants the master bedroom quiet enough for a night-shift partner to sleep past 11am.
- ·The owner wants the property to look less like a rental and more like a home, and the front door does most of that work.
How we actually fit it
- ·The frame is protected with a low-tack film across any face a tool might touch 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 frame perimeter sealant is a low-modulus polymer where the substrate is going to move — plain silicone otherwise.
- ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
- ·The glass has a factory kite mark visible at handover — not scraped off by a lazy cleaner during the fitting hour.
- ·The client's alarm sensors on the old frames are removed and returned to the client, not binned by default.
- ·The multipoint keeps get a smear of grease inside the pocket before the door is closed for the first time.
- ·The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
- ·The multipoint hooks are lightly greased after fitting, before the door is closed for the first time.
- ·The friction stay screws are torque-limited, not driven at full trigger — over-driven screws strip the stay chamber.
- ·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.
- ·The cylinder key gets a keyring immediately, so it does not sit unnoticed in a jacket pocket for the day.
- ·The frame is protected with a low-tack tape at any point a tool might scrape it during the fitting hour.
- ·The lead fitter photographs the reveal condition before the old frame comes out and shares those photos with the office.
- ·Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
- ·The bathroom obscure glass pattern is confirmed with a physical sample against the existing pane, not chosen from a brochure image.
- ·The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.
- ·The internal architrave is coped rather than mitred where the reveal wall is out of true.
- ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
- ·The crew asks the client where the kettle lives before they set up so tea gets made rather than negotiated.
- ·The mitre joins on any Georgian bar are picked to face the corner that is least visible from indoors.
- ·The client is walked through the operation of every lock, every vent, and every restraint before the crew leaves.
- ·The trickle-vent covers are set with their vane orientation matched across a bank of windows for visual consistency.
- ·The frame drainage caps are proven flowing before the beading goes in — a bottle of water down the outer chamber.
- ·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 threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
- ·The perimeter airtight tape is applied over the frame flange in a single unbroken run around all four sides.
- ·The dustsheet inside the room is a heavy canvas taped to the skirting, not a light plastic left loose.
- ·The crew calls the client at 5pm the day before to confirm arrival window and site access details.

Questions we get on 1960s new-town homes jobs like this
What guarantee comes with full-house replacement here?+
10-year product on every frame, 2-year fitting on the whole package, single point of contact, and it applies the same whether the property is a 1960s new-town homes in Cardiff or anything else on our books. Insurance and paperwork are supplied with the completed job.
Will planning rules affect full-house replacement on this kind of property?+
New-town estates are rarely restricted at the front-door level, though large glazing swaps sometimes need building regs sign-off for structural loading. We check the position with Cardiff Council before anything is ordered so there is no surprise after manufacture.
What tends to push the price up on a 1960s new-town homes?+
Three things, in order: the state of the timber or brick behind the old frame, whether the opening has been altered at some point, and glass size. Timber-frame walls need careful frame fixing — long screws into the studs, not the outer skin is the one that catches people out. Around Cardiff we quote the making good in writing rather than treating it as an extra on the day.
Do you fit full-house replacement on 1960s new-town homes around Cardiff?+
Regularly. Cyncoed, CF10 is where most of this work lands, and we also cover Penarth, Caerphilly, Barry. 10 miles from base, A470 the whole way — Cardiff installs run as smoothly as our home patch.
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.
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.

Book a survey and you'll have a full-house replacement figure for your 1960s new-town house inside 24 hours.

Original developer composite slabs often warp under southern sun; a replacement 48mm slab with GRP skin resists. No pressure sell, no deposit until a date is confirmed. Around Cardiff that usually means heritage-friendly frame profiles in conservation streets on Edwardian and Victorian bay-fronted houses in Cathays and Roath, 1930s semis in Llanishen, modern builds in Pontprennau, with Cyncoed and Llanishen the streets we are on most. 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.
