Owner occupiers doing the whole property in one go
Owner occupiers doing the whole property in one go around Caerphilly: what changes
Whole property work is a different purchase to a single replacement. You are buying two to four days of disruption, a matched set of frames and one point of contact, so this page concentrates on those three things.
What this buyer actually needs from us
- One named contact from first call through to the snagging visit
- A programme that keeps the house lockable and weathertight every night
- The glazing bead is tapped in with a rubber mallet, not a metal claw — the profile marks otherwise.
- The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.

How a full house install runs
We work to a set sequence so the house is never fully opened up at once and so neighbours and parked cars are not blocked for a week. Front elevation first, then the sides, then the rear, with the front door usually last so the property stays secure while the windows go in.
- Free survey, every opening measured and photographed
- Written quote within 24 hours listing each window and door separately
- Manufacturing lead time confirmed in writing before deposit
- Install typically 2 to 4 days depending on the number of openings
- Dust sheets inside, rubbish cleared every evening, no skip left for weeks
- Snag visit about a week later to adjust anything that has settled
What goes into a whole house package
A package priced together is cheaper than the same work done room by room, and everything matches. That matters more than people expect on a front elevation where one new window next to five old ones is obvious from the pavement.
- A rated uPVC or thermally broken aluminium frames across every elevation
- One consistent foil or RAL colour on the whole property
- Composite front door and a back or patio door as a coordinated set
- Matching hardware finish on every window and door
- Trickle vents where the regulations require them
- Optional triple glazing on road facing or exposed elevations only, where it earns its cost
Why a whole house beats one window at a time
Replacing a window at a time feels cheaper and rarely is. Each visit carries its own labour and delivery, the colours and profiles drift as ranges change, and the failing frames you left in place keep costing you in heat while you wait. Doing the property in one go gives you a single guarantee, one team who knows the house, and a finish that reads as deliberate rather than patched.
It is also the point at which it is worth thinking about the doors. If the windows are being done, the front and back doors are usually the same age and will fail on the same timescale.
Full house work across Caerphilly
We have replaced whole properties across CF83, on the terraces near the town centre, the semis at Penyrheol and Trecenydd, and the estates at Energlyn and Llanbradach, along with Bedwas, Machen, Abertridwr and Ystrad Mynach. Terraced streets need the most planning, because there is nowhere to stage frames, so we deliver in stages rather than filling the pavement.
Common questions
How much does a full house of windows and doors cost in Caerphilly?
It depends entirely on the number of openings, the frame material and the doors included, so we survey and quote in writing rather than give a figure that turns out to be wrong. The quote lists each opening separately so you can see what everything costs.
How long will my house be disrupted?
Most Caerphilly properties take 2 to 4 days. Only one elevation is open at a time and the house is secure and weathertight every night.
Can I include the front door in the same job?
Yes, and most customers do. Pricing the composite front door with the windows means one guarantee, one team and matching hardware throughout.
Do you offer any guarantee on the whole package?
A 10 year product guarantee on every frame, a 2 year fitting guarantee across the whole package and a single point of contact for the life of it. We are fully insured and rated 10 out of 10 on Checkatrade.
What we typically find on full-house replacement surveys around here
- ·The bottom track on the sliding door has a build-up of grit that the rollers grind through every open cycle.
- ·The trickle-vent screw covers are missing and the internal chamber has filled with cobweb.
- ·A previous cylinder swap left the escutcheon plate rotating freely — a snap risk that nobody logged.
- ·A tenant repair on the bathroom window has used bathroom silicone as the primary bead — it's already gone black.
- ·Original door furniture is 90s brass, tarnished, and no longer matches anything else on the elevation.
- ·The door-side glazed sidelight has a shattered internal pane held together by the laminated interlayer.
- ·The internal reveal architrave has been re-fixed with panel pins that have rusted and stained the paintwork.
- ·The letter plate cover has snapped off and the exposed brush strip has flattened over the years.
- ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
- ·The cill end-cap has fallen off and the cill chamber is now a home for insects.
- ·The bottom rail on the sash has taken years of rain runoff and swollen enough to bind on the frame.
- ·The front door threshold weather-bar seal is missing its rubber blade and the metal channel is bent.
- ·The internal locking cams on the multipoint have been ground down by a mismatched keep pattern.
- ·The window opens fine on a cold morning and binds by 3pm on a hot afternoon — classic thermal-expansion bind.
- ·The old timber sub-cill under a uPVC swap is boron-treatable but only if we lift the frame off it cleanly.
Why residents are booking full-house replacement right now
- ·The owner is done with rattling frames in a westerly and wants a demonstrable acoustic upgrade, not a numerical claim.
- ·The owner is done with the annual condensation season and wants the fabric of the openings to end it.
- ·The owner wants the front door to feel expensive to close — the weight, the sound, the drop of the latch.
- ·The homeowner has quotes for a new kitchen next spring and wants the patio doors in before those trades arrive.
- ·The resident wants the sliding door to open with a fingertip after ten years of use, not two hands after two.
- ·The homeowner wants the composite slab to be paintable without voiding the manufacturer warranty.
- ·The resident cycles to work and wants a bike-in-porch design that a survey needs to plan around.
- ·The owner wants a threshold that does not require a step for a mobility scooter to clear.
- ·The owner wants the whole property refurbished for a big family gathering nine weeks out — everything sequenced tightly.
- ·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 homeowner wants the crew to catch anything the vendor's survey missed while they're on site.
- ·The wife wants the noise from the trunk road down; the husband wants the heating bill down; both are on the enquiry.
- ·There is a downstairs shower being fitted and the bathroom window needs to be swappable before the tiler starts.
- ·The resident wants the front to look distinct on a street of five identical houses.
- ·The buyer wants the porch to stay a porch and not turn into a mud room by function.
- ·The homeowner is targeting a specific EPC band ahead of a rental switch and needs the frames to contribute measurably.
How our fitters actually do the work
- ·Ground protection sheet goes down before the old frame comes out — not after the mess starts.
- ·We de-glaze into a padded rack, not straight into the skip — the intact panes go to a glazier for reuse.
- ·The internal make-good caulk is polymer, tooled with a wet finger and then a spatula for a final radius.
- ·The old frame is removed by cutting the corners with a reciprocating saw rather than a lever bar that damages the reveal.
- ·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 new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The crew takes the old glass off site in a labelled sack that day, not a skip left on the drive.
- ·The client is walked through the operation of every lock, every vent, and every restraint before the crew leaves.
- ·The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.
- ·The friction stay screws are torque-limited, not driven at full trigger — over-driven screws strip the stay chamber.
- ·The multipoint gearbox is thrown by hand before the frame goes in — a factory fault at that point is a five-minute fix.
- ·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 bay-corner post is set with a laser level across both faces before the outer frames are trimmed to fit.
- ·The internal architrave is scored along its length with a fresh blade before removal, so the wallpaper does not tear back.
FAQs — full-house replacement in Caerphilly
How do you reach jobs in Caerphilly from your base?+
Easy in via the A469, and we're 10 minutes from the A470 for vans loaded with full-house glass — typically a short run via A468.
Why replace the whole set rather than one-by-one in a Caerphilly home?+
Because the false economy of replacing one tired window at a time while the others keep failing rarely stays isolated — once one unit goes, the rest follow within a few years. Doing it once means matching frames across the elevation and one trip for our team into CF83.
How long does a full-house replacement install take in a Caerphilly property?+
Typically 2–4 days depending on count, with a final snag visit a week later. Most of the stone-fronted terraces we see in Caerphilly fit our standard schedule with no surprises.
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 stone-fronted terraces in real light.
Will full-house replacement suit the older stone-fronted terraces common around Caerphilly?+
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 Bedwas and Trethomas alone.
Can I stage a whole house replacement over two visits?+
Yes. Front elevation and front door first, rear later is a common split. It costs slightly more overall than doing everything in one visit and we will show you the difference in writing before you decide.
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.

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.
