Full House Window & Door Replacement on a 1960s new-town home in Cwmbran
If you've got a 1960s new-town house on your hands in Cwmbran, the recurring problem when quoting full-house replacement is original 60s sliding aluminium frames cold-bridge and ice up internally. The false economy of replacing one tired window at a time while the others keep failing is the paired issue you'll usually hear about at the same visit. Our spec here is A+ uPVC or aluminium frames with argon-filled units. Estate roads are wide and van-friendly — we can leave the truck in one spot for the whole day without moving. Bay ceiling drops usually have a beam boxed in above — we route silicone around the boxing edge rather than through it. Rural cottages often have limited off-road parking; the van sits on the road and the crew boards through the front door. Rural access often includes a farm gate and a narrow lane — we check turn-in width at survey. Hardware fails on schedule at year 8–10; upgrading hinges alone during a full re-glaze extends the frame life a decade. Original oak lintels can be scored and treated, not replaced, when they sit sound above a new frame. 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. 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.

Common 1960s new-town homes problems we quote full-house replacement for
- 1Original single-glazed sliders leak heat at every gasket.
- 2Walkway-facing entrances mean the door reads at close range from the street.
- 3Original 60s sliding aluminium frames cold-bridge and ice up internally.
What we typically find on survey
- ·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
- ·The multipoint deadbolt still throws but the top hook has stopped catching and no one has noticed for months.
- ·One handle turns freely through 180° with no engagement — a snapped internal cam.
- ·One casement's friction stay has been swapped for a random spare that doesn't match the arm geometry.
- ·The georgian bar between the panes has come detached from the top spacer on one unit.
- ·A homemade timber threshold has been screwed to the concrete cill in front of the patio door.
- ·The outer frame has moved fractionally over the years, dropping the bottom hinge screw pattern out of line.
- ·The frame drainage slots at the bottom are clogged with debris, so rainwater sits inside the chamber.
- ·The frame colour has gone chalky on the sun side and stayed factory white on the shaded elevation.
- ·The stay arm on the top vent has bent and no longer sits into its rest bracket cleanly.
- ·A cracked pane has been temporarily patched with clear tape and left for six months.
- ·There is a permanent green algal streak below the sill where water is bypassing the drip groove.
- ·The Yale night-latch on top of the multipoint is a sign the resident does not trust the primary lock.
- ·The trickle vents are painted shut and the room fugs up within an hour of the kettle going on.
- ·Original security stickers from the installer are still on the bottom of the panes, twenty years later.
- ·One patio-door interlock has a bent alignment lug — the door jams shut half of the time.
- ·The internal window board has swelled at the sink end from years of splash and is delaminating along the front edge.
- ·The sealed unit is a 20mm gap, not the modern 28mm minimum, so U-values are into the mid-2s at best.
- ·The cill end-cap has fallen off and the cill chamber is now a home for insects.
- ·There is a hairline crack running diagonally from the top corner of one bathroom pane where the frame has twisted.
- ·A previous cylinder swap left the escutcheon plate rotating freely — a snap risk that nobody logged.
- ·Every casement in the property opens with a firm tug on the second click — the friction stays are seized.
- ·The internal glazing bead sits proud of the frame by 1.5mm, so the seal at the top corner has failed first.
- ·Two units have the classic dust ring inside the sealed gap, meaning the perimeter seal has been breached for at least a year.
- ·The manufacturer's kite mark on the corner of the glass is late-90s vintage, which explains the thermal performance.
- ·The georgian bar between panes on one unit has slipped off its top spacer and is sitting diagonally inside the sealed cavity.
- ·The front door threshold weather-bar seal is missing its rubber blade and the metal channel is bent.
- ·There is a paint bridge from the internal architrave to the frame that will crack the moment the new unit lifts out.
- ·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 bathroom obscure glass pattern has been discontinued for over a decade — matching a single pane is not possible.

- ·The internal trim goes on with pin nails through the flange, not straight through the visible face.

- ·The frame perimeter is checked with a smoke pencil for airtightness before the internal trims go on.
- ·The lead fitter photographs the reveal condition before the old frame comes out and shares those photos with the office.
- ·The trickle-vent covers are set with their vane orientation matched across a bank of windows for visual consistency.
- ·The internal make-good caulk is polymer, tooled with a wet finger and then a spatula for a final radius.
- ·The crew photographs the finished elevation from the street and shares it with the office as the sign-off record.
- ·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
- ·The bay-corner post is set with a laser level across both faces before the outer frames are trimmed to fit.

- ·The multipoint keeps get a smear of grease inside the pocket before the door is closed for the first time.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.
- ·Every silicone bead is tooled with the correct radius spatula, not smoothed with a wet finger only.
- ·The crew leaves the client with a printed adjustment card so the multipoint keeps can be re-set six months on without a callout.
- ·Door thresholds are set with a spirit level along their full length and then re-checked with a straight edge.
- ·The perimeter airtight tape is applied over the frame flange in a single unbroken run around all four sides.
- ·The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.

- ·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 on the internal reveal is patched with matching paint the crew brings, not left for someone else.
- ·The bathroom obscure glass pattern is confirmed with a physical sample against the existing pane, not chosen from a brochure image.
- ·The dustsheet inside the room is a heavy canvas taped to the skirting, not a light plastic left loose.
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The letterplate brush strip is trimmed to the exact height of the door thickness so it seals without dragging.
- ·The bay assembly is squared with a laser diagonal, not a tape measure and eye.
- ·The crew asks the client where the kettle lives before they set up so tea gets made rather than negotiated.
- ·Ground protection sheet goes down before the old frame comes out — not after the mess starts.

Questions we get on 1960s new-town homes jobs like this
How long does a full-house replacement job take on a 1960s new-town homes?+
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 60s sliding aluminium frames cold-bridge and ice up internally, which we allow for at survey rather than discovering it on fitting day.
Is it worth upgrading the whole elevation rather than one opening?+

How much disruption should we expect inside?+
Dust sheets down, one room at a time, and the old units carried out through the nearest external door rather than through the house where we can. On a 1960s new-town homes the internal plaster reveal is the sensitive part, so we cut the old frame out rather than lever it.

Do I need permission to replace windows on a character property?+

Will modern frames look wrong on an older house?+
They can, if the profile is chosen badly. Flush sash sits back into the reveal and keeps the sightline slim, which is why we specify it on older elevations rather than standard chamfered casements.

Summary — full-house replacement on a 1960s new-town house in Cwmbran
1960s new-town house jobs in Cwmbran 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. External cill drips block with paint over the decades — raking them clean stops water sitting on the frame after install. Original front cills are usually blue engineering brick — leave them, drill through them for the frame fixings. Around Cwmbran that usually means original 60s-spec crittall or 90s uPVC failing on new-town semis on new-town 1960s and 70s estates with a mix of semis, town houses and low-rise flats, plus newer Persimmon/Barratt closes on the fringes, with Croesyceiliog and Llantarnam the streets we are on most. 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. 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.
