Written for owner occupiers replacing one door or one window
Most enquiries at this size start with one specific fault. This page covers what that fault usually turns out to be locally, what the fix costs relative to a full replacement, and when it is worth waiting and doing more openings together.
What matters most on this kind of job
- A straight answer on whether the existing frame can be repaired instead
- A short arrival window rather than a whole day waiting in
- The old handles are offered to the client before being binned — sometimes a chrome D-handle finds a shed door life.
- The bead-in tools are rubber-faced, not steel — a steel tool marks the profile within minutes.

What we typically find on casement windows surveys around here
- ·The internal glazing bead across the top of the bay lifts out completely with fingernail pressure.
- ·The gasket join at the bottom corner has separated by a few millimetres — that's where the draught is coming from.
- ·The frame colour has gone chalky on the sun side and stayed factory white on the shaded elevation.
- ·The friction stays are the wrong hand for the sash — a previous swap fitted left-hand stays on a right-hand window.
- ·There is a permanent green algal streak below the sill where water is bypassing the drip groove.
- ·The manufacturer's kite mark on the corner of the glass is late-90s vintage, which explains the thermal performance.
- ·The bathroom obscure glass pattern has been discontinued for over a decade — matching a single pane is not possible.
- ·One handle turns freely through 180° with no engagement — a snapped internal cam.
- ·The old timber back door has a live rot pocket at the bottom hinge that reads soft to a screwdriver tip.
- ·A previous fitter drilled through the outer frame chamber for the trickle vent — never fully sealed the drilling.
- ·One casement's friction stay has been swapped for a random spare that doesn't match the arm geometry.
- ·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
- ·The internal reveal plaster is spalling under the cill where condensation has run for years.
- ·Original security stickers from the installer are still on the bottom of the panes, twenty years later.
- ·The letter plate cover has snapped off and the exposed brush strip has flattened over the years.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
Why residents are booking casement windows right now
- ·The buyer wants the porch to stay a porch and not turn into a mud room by function.
- ·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 a threshold that does not require a step for a mobility scooter to clear.
- ·The resident wants the front door to sound solid when it closes — a hollow slap does not read as secure.
- ·The resident cycles to work and wants a bike-in-porch design that a survey needs to plan around.
- ·The current front door leaks visibly around the letterplate every time the wind swings east.
- ·The resident does not want to be sold to — they want a survey, a written figure, and to be left to decide.
- ·The insurance renewal notice flagged a locks upgrade requirement and the owner wants it done before the policy anniversary.
- ·The resident wants an installer who will point out things the current property is doing well and leave those alone.
- ·The homeowner is preparing the property for a smart-home installation and wants sensor pockets designed into the reveals.
- ·The owner wants the front door to feel expensive to close — the weight, the sound, the drop of the latch.
- ·The homeowner has an infrared thermometer and has been point-checking the frames — they want the readings up by ten degrees.
- ·The homeowner wants the back door to be a family door — kids in and out, and no one having to slam it to lock.
- ·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.
- ·The homeowner wants matt black hardware because everything inside the house is matt black — no chrome to argue with.
- ·The homeowner is done with the whistle the front door letterplate makes in a north wind.
How our fitters actually do the work
- ·The internal skirting is protected with a strip of packing tape across the top edge before any tool touches it.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.
- ·The perimeter foam goes in in two passes so the second lift meets the first without a void in the middle.
- ·Cylinders come out of the box, get numbered, and are the last thing fitted, so a lost cylinder does not stall the day.
- ·The site tidy happens twice per day, not once at the end, so brick dust doesn't track through the house.
- ·The trickle vent chamber inside the frame is proven clear with a torch before the outer cap goes on.
- ·The dustsheet inside the room is a heavy canvas taped to the skirting, not a light plastic left loose.
- ·The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·The frame square is checked at the diagonals before any glass goes in — a square frame stays square.
- ·The friction stay screws are torque-limited, not driven at full trigger — over-driven screws strip the stay chamber.
- ·The crew asks the client where the kettle lives before they set up so tea gets made rather than negotiated.
- ·The concrete cill under the frame is checked for cracks; a hairline gets a slurry fix before the frame is set.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The internal make-good caulk is polymer, tooled with a wet finger and then a spatula for a final radius.
- ·The frame reinforcing steel is confirmed inside the top rail before the transom fixing is chosen.
FAQs — casement windows in Caerphilly
Will casement windows suit the older stone-fronted terraces common around Caerphilly?+
Side-hung casements clean easily from inside — helpful on the tighter Pontypridd and Cardiff terraces where there's no rear access to a ladder. We've installed dozens in Bedwas and Trethomas alone.
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.
Do you cover Cardiff and Newport as well?+
Yes — Cardiff is roughly 7 miles from Caerphilly, Newport about 11. Same team, same prices, same guarantee.
What colours and finishes are available for casement windows?+
side-hung, top-hung or fixed pane combinations; white, anthracite, black, cream or foiled woodgrain; trickle vents to Part F where required. We bring physical samples to the quote so you can see them against your stone-fronted terraces in real light.
What guarantee do I get when you fit casement windows in Caerphilly?+
10-year product, 2-year fitting, lifetime hardware servicing. We're insured to work right across Caerphilly County Borough Council's area, and you have one named contact from quote to snag.
Do you take on single window or single door jobs?+
Yes, and there is no minimum order. A single opening is usually a half day, including removing the old frame and making the reveal good inside and out.
Will one new unit match the older frames already fitted?+
We match profile, colour and hardware finish as closely as the current stock lines allow, and we will tell you honestly at survey where an exact match is not possible.

Summary — casement windows in Caerphilly
Sticky old aluminium or timber casements that whistle in wind and won't hold open against a breeze won't fix itself, and putting it off through another winter in Caerphilly just costs more in heating, particularly with wind-driven rain off the mountain ridge working on the elevation every week. A 20-minute call gets the survey on the diary. On casement windows specifically: sticky old aluminium or timber casements that whistle in wind and won't hold open against a breeze, 1 window in 90 minutes, full-house in 1–3 days, 10-year product, 2-year fitting, lifetime hardware servicing.
Faults we fix before recommending casement 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.
