New full-house replacement for Cardiff homes
Property type drives the brief in Cardiff more than budget does. Edwardian and Victorian bay-fronted houses in Cathays and Roath, 1930s semis in Llanishen, modern builds in Pontprennau — and each one calls for a different full-house replacement approach. We've quoted city professionals from Llanishen through to landlords near Cardiff Bay, Capital Business Park, and the spec is rarely identical twice. 10-year product on every frame, 2-year fitting on the whole package, single point of contact on every quote.

Owner occupiers doing the whole property in one go
Owner occupiers doing the whole property in one go around Cardiff: what changes
This page is written for the household replacing every opening at once rather than picking off one window a year. The decisions that matter are sequencing, how long the house is open, and whether the price holds from survey to final invoice.
What matters most on this kind of job
- An itemised written price so single openings can be added or dropped
- A programme that keeps the house lockable and weathertight every night
- The door slab gets a full inspection before hanging — dents, delamination, edge integrity, all noted before fixings go through.
- The install team pull the fridge out for kitchen-window swaps only after checking the flooring can take the drag scuff.
Full public liability insurance and a written two year fitting guarantee on the package

What we typically find on full-house replacement surveys around here
- ·The georgian bar between the panes has come detached from the top spacer on one unit.
- ·A cat flap has been cut through the lower panel of the back door, weakening the panel and voiding warranty.
- ·One kitchen unit has a defrost trace across the low-e coating — the argon fill has been gone a while.
- ·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 old aluminium sliding door has grit in the track that has worn the roller wheels to elliptical.
- ·The trickle-vent covers have been snapped off and taped over from inside.
- ·A cracked pane has been temporarily patched with clear tape and left for six months.
- ·The concrete cill under the door has heaved by 3mm across the two-metre span, tilting the whole threshold.
- ·The old timber sub-frame under the current uPVC unit is still in place and is soft at the bottom left corner.
- ·One handle turns freely through 180° with no engagement — a snapped internal cam.
- ·One patio-door interlock has a bent alignment lug — the door jams shut half of the time.
- ·The letterplate has a hinged internal flap that has snapped off and is currently held in place with masking tape.
- ·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
- ·The Yale night-latch on top of the multipoint is a sign the resident does not trust the primary lock.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·The front door has been painted three times without stripping — the paint film is now stopping the door closing at the top.
Why residents are booking full-house replacement right now
- ·The resident is expecting an elderly parent to move in and needs a door that opens without a shove.
- ·The buyer wants a composite door slab that a courier's boot cannot dent when a delivery is fumbled.
- ·The homeowner wants matt black hardware because everything inside the house is matt black — no chrome to argue with.
- ·The homeowner wants a single date, a single crew, and a single guarantee — not a paper trail across three companies.
- ·The owner has watched the bay corner posts sag for a decade and now wants them straight and structural.
- ·The resident has a shift-worker sleeping in the day and needs the bedroom to be a genuine acoustic step change.
- ·The homeowner is fine spending more if the crew is right — the price is the last question, not the first.
- ·The resident wants the patio door to slide with one finger — not the two-handed heave the current one takes.
- ·The owner wants the frames to disappear visually and let the view do the work.
- ·The homeowner is done with the whistle the front door letterplate makes in a north wind.
- ·The buyer is done with the sound of the frames rattling in a gale.
- ·The resident is on a listed street and wants a front door that will pass Article 4 first time.
- ·The resident wants the sliding door to open with a fingertip after ten years of use, not two hands after two.
- ·The homeowner is preparing to work from home permanently and wants the office quieter than the living room used to be.
- ·The homeowner has just re-rendered the front elevation and wants the frames to be the last piece of the picture.
- ·The owner just remortgaged and wants the money to be visible on the elevation for the next valuation.
How our fitters actually do the work
- ·The door slab gets a full inspection before hanging — dents, delamination, edge integrity, all noted before fixings go through.
- ·The head of the frame is packed dry before the sides are fixed, so the frame does not distort during installation.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.
- ·The crew asks the client where the kettle lives before they set up so tea gets made rather than negotiated.
- ·The internal make-good caulk is polymer, tooled with a wet finger and then a spatula for a final radius.
- ·The trickle vent chamber inside the frame is proven clear with a torch before the outer cap goes on.
- ·The internal architrave is coped rather than mitred where the reveal wall is out of true.
- ·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's paint colour on the internal reveal is patched with matching paint the crew brings, not left for someone else.
- ·The threshold sealant runs the full width with a single tool pass, not stitched together in inches.
- ·The threshold is bedded on butyl mastic under the outer skin, giving the fitter a second waterproof line behind the perimeter silicone.
- ·The crew photographs the finished elevation from the street and shares it with the office as the sign-off record.
- ·The window boards are pre-treated on the underside with a moisture seal before setting in place.
- ·The internal beads are numbered on removal so they return to the same corner they came from.
- ·The old frame is removed by cutting the corners with a reciprocating saw rather than a lever bar that damages the reveal.
- ·The letterplate is fitted with the internal flap set to close under its own weight without dragging.
FAQs — full-house replacement in Cardiff
Will full-house replacement suit the older Edwardian and Victorian bay-fronted houses in Cathays and Roath common around Cardiff?+
We sequence the install so terraced neighbours and parked cars aren't blocked all week — a real concern on Welsh valley streets. We've installed dozens in Cyncoed and Llanishen alone.
What colours and finishes are available for full-house replacement?+
one consistent foil/RAL across every elevation; front door, back door and patio doors as a coordinated set. We bring physical samples to the quote so you can see them against your Edwardian and Victorian bay-fronted houses in Cathays and Roath in real light.
Can full-house replacement handle heritage-friendly frame profiles in conservation streets?+
Directly, yes — whole property reset to a-rated thermal performance for a 20-year horizon. That matters in Cardiff where heritage-friendly frame profiles in conservation streets is the single most common reason people call us.
How long does a full-house replacement install take in a Cardiff property?+
Typically 2–4 days depending on count, with a final snag visit a week later. Most of the Edwardian and Victorian bay-fronted houses in Cathays and Roath we see in Cardiff fit our standard schedule with no surprises.
How do you reach jobs in Cardiff from your base?+
10 miles from base, A470 the whole way — Cardiff installs run as smoothly as our home patch — typically a short run via A48.
Do I have to use the same specification in every room?+
No, and it is usually cheaper not to. Triple glazing where noise or cold is the real complaint, A rated double elsewhere, obscure glass in bathrooms. We price the options side by side at survey.
Will the house be secure overnight during a full replacement?+
Yes. Only one elevation is open at a time and every opening we start is finished, glazed and locked before we leave for the day.

Faults we fix before recommending full-house replacement
A draught is usually a compression problem — gasket, hinge or seal — long before it's a reason to replace the window.
Rot in the bottom rail is repairable; rot that has reached the joints and the cill usually isn't worth chasing.
Yellowing is cosmetic and treatable; splits at the welded corners are structural and aren't.
