Owner occupiers doing the whole property in one go
Buying uPVC windows as owner occupiers doing the whole property in one go
The reader here has decided the whole property needs doing and is now comparing installers rather than products. That means the useful information is programme length, who is actually on site, and what the written quote covers opening by opening.
What this buyer actually needs from us
- One survey covering every opening, measured and photographed
- An itemised written price so single openings can be added or dropped
- The perimeter tape between frame and reveal is a compressible foam tape, not a plain butyl strip.
- The keeps for the multipoint are set with the door open and the position marked, not adjusted by eye once the door is closed.

The window specification we fit as standard
Our standard uPVC window is a multi chamber 70mm profile with steel reinforcement in the sashes, glazed with a 28mm argon filled unit and a low emissivity soft coat inner pane. That combination is what earns an A rating, and it is what we quote unless you ask for something different.
- 70mm multi chamber A rated profile with steel reinforced sashes
- 28mm argon filled sealed unit with warm edge spacer bar
- Low emissivity coating on the inner pane to hold heat in the room
- Espagnolette shootbolt locking with internally beaded glazing
- Friction stay hinges with child safety restrictors set at 100mm
- Trickle vents fitted where Part F of the building regulations requires them
Window styles for Caerphilly homes
Style is not just a look. It changes how the window cleans, how much daylight you keep and whether it suits the front of the property.
- Casement, side hung or top hung, the standard on most CF83 properties
- Flush sash, which sits level with the frame and suits stone fronted and period houses
- Tilt and turn, which cleans from inside and works well on upper floors with no rear access
- Bay and bow windows, common on the Edwardian terraces and 1930s semis here
- Vertical sliding sash in uPVC for properties where the original sash look matters
- Fixed panes and Georgian or astragal bars where the original glazing had them
Colours and glazing choices
White is still the most common choice in Caerphilly, but anthracite grey outside with white inside has overtaken it on newer estates. Foiled finishes are applied to the profile rather than painted, so they do not need repainting.
- White, cream, anthracite grey, black, chartwell green and foiled woodgrains
- Dual colour, one finish outside and white inside
- Obscure glass graded 1 to 5 for bathrooms and ground floor side elevations
- Toughened safety glass in any pane below 800mm from the floor, as required
- Triple glazing available where noise or cold is the main complaint
Why Caerphilly windows fail
The three complaints we hear most in CF83 are misted units, condensation pooling on the cill and a cold draught felt from a seat by the window. Misting means the seal on the sealed unit has failed and the unit itself needs replacing, which we can do without changing the frame if the frame is sound. Draughts are usually gasket or hinge wear rather than the frame being finished, and we will tell you honestly which it is at the survey rather than sell you a full replacement you do not need.
Where the frames genuinely are at the end of their life, usually 1990s installations with dropped sashes and blown units across several rooms, replacement is the sensible answer and a whole house makes more sense than a window at a time.
What a fitted window price covers
We quote per window and as a whole house figure so you can see both. Whatever the size of the job, the written price includes everything below.
- Free survey and a written quote within 24 hours
- Removal and disposal of the old frames and glass
- New frames sat on hardwood packers, fixed, foamed and sealed
- Internal trims and external silicone pointing
- Reinstatement of cills where needed
- 10 year product guarantee, 2 year fitting guarantee, lifetime hardware servicing
- Dust sheets used inside and the site cleared each evening
Common questions
Can you replace just the misted glass instead of the whole window?
Usually yes. If the frame and hinges are sound we can replace the failed sealed unit on its own, which is far cheaper than a new window. We will tell you at the survey which option genuinely makes sense.
How long does a full house of windows take in Caerphilly?
Most Caerphilly houses are done in 1 to 3 days depending on the number of openings. We work front elevation first, then sides, then rear, and clear up each evening.
Do new windows help an EPC rating?
Replacing single glazing or failed early double glazing with A rated units improves the glazing element of an EPC. It is one part of the rating rather than the whole of it, so we would not promise a specific band.
Are your windows made to measure?
Yes. Every window is surveyed on site and manufactured to that opening, which matters on the older Caerphilly terraces where reveals are rarely square.
What we typically find on uPVC windows surveys around here
- ·A weep vent that was factory-drilled has been over-painted three times and no longer clears water from the chamber.
- ·The hinges are all dropped one notch from level, taking the sash out of square against the outer frame.
- ·The window boards inside are chipboard, swollen at the edges from years of trickle condensation.
- ·The letterplate is a straight through-plate with no anti-snap flap — visible from outside in the hallway.
- ·The bottom track on the sliding door has a build-up of grit that the rollers grind through every open cycle.
- ·The frame reinforcement steel inside the outer frame has begun to rust and stain the internal white finish.
- ·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.
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·The escutcheon plate on the back door hides a botched cylinder swap where the follower is worn.
- ·Every south-facing frame has visible micro-cracking in the surface film — early sign of UV embrittlement.
- ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
- ·The old aluminium sliding door has grit in the track that has worn the roller wheels to elliptical.
- ·The window opens fine on a cold morning and binds by 3pm on a hot afternoon — classic thermal-expansion bind.
- ·One kitchen unit has a defrost trace across the low-e coating — the argon fill has been gone a while.
- ·The kitchen window has a defrost line across the low-e coating — argon gas long gone.
Why residents are booking uPVC windows right now
- ·The resident is fitting a home cinema in the front room and needs the windows to be a full acoustic upgrade, not a nominal one.
- ·The resident wants the letterbox to stop being a draught source without giving up daily post.
- ·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 homeowner is planning a garden studio and wants the patio doors to bookend the view when it's finished.
- ·The owner is preparing the elevation for a specific street-photo listing and wants the finish to be photographable in raking morning light.
- ·The buyer wants the property to look owned rather than tenanted — the front door tells that story first.
- ·The homeowner is 68 and wants a threshold that will still be usable in ten years without a step.
- ·The owner wants the master bedroom quiet enough for a night-shift partner to sleep past 11am.
- ·The homeowner is expecting twins and wants the room-to-room noise transfer down before the arrival.
- ·A recent break-in on the street has moved security up the priority list ahead of aesthetics.
- ·The buyer wants the sound of the sea audible but the wind noise gone.
- ·The owner wants the frames to disappear visually and let the view do the work.
- ·The owner is having a kitchen refit next month and wants the patio door in first so the tiler works to a fitted threshold.
- ·The buyer wants a composite front door that reads more house-proud than the run of identical rentals on the road.
- ·The owner is done paying to service failing 90s uPVC every couple of years and wants the whole set replaced together.
How our fitters actually do the work
- ·The keeps for the multipoint are set with a strike plate template, not marked by eye against the closed door.
- ·The crew photographs the finished elevation from the street and shares it with the office as the sign-off record.
- ·The internal skirting is protected with a strip of packing tape across the top edge before any tool touches it.
- ·The bathroom obscure glass pattern is confirmed with a physical sample against the existing pane, not chosen from a brochure image.
- ·The internal cill is scribed to the reveal, not just butted and caulked over the gap.
- ·The frame is plumbed on two axes before the first fixing goes in — not one axis and then trusted.
- ·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
- ·The crew leaves the client with a printed adjustment card so the multipoint keeps can be re-set six months on without a callout.
- ·The composite slab is not trimmed on site — if it doesn't fit, a new slab is ordered rather than reduced.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·The site tidy happens twice per day, not once at the end, so brick dust doesn't track through the house.
- ·The frame perimeter sealant is a low-modulus polymer where the substrate is going to move — plain silicone otherwise.
- ·Cylinders come out of the box, get numbered, and are the last thing fitted, so a lost cylinder does not stall the day.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise, checked with a spirit-level lip.
- ·The gasket wedges are trimmed with a fresh knife blade for every unit — a dull blade tears the EPDM.
- ·The friction stay on a new casement is set to the client's preferred restraint at handover — 45°, 90°, or fully open.

Faults we fix before recommending uPVC windows
Fog between the panes means the sealed unit has failed — the glass can usually be swapped without touching the frame.
A draught is usually a compression problem — gasket, hinge or seal — long before it's a reason to replace the window.
Which face the water sits on tells you everything: inside is ventilation, between the panes is a failed unit, outside is normal physics.
Rot in the bottom rail is repairable; rot that has reached the joints and the cill usually isn't worth chasing.
