New patio doors for Caerphilly homes
Most of our patio doors jobs in Caerphilly start with the same call: "tired 80s sliding aluminium doors that stick, lose heat and rattle in the wind". Around here that usually means a stone-fronted terraces where the original frames have given up. We work right across CF83 — Bedwas, Trethomas, Machen and the surrounding streets — typically arriving via A468. Lintel and floor checked for level, track set with stainless packers, doors hung and aligned so they roll true under their own weight.

Owner occupiers doing the whole property in one go
Why patio doors look different to owner occupiers doing the whole property in one go
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
- A programme that keeps the house lockable and weathertight every night
- Old frames, sashes and glass taken away rather than left in the garden
- The manufacturer's serial-number label on the new frame is peeled off, not left to yellow on the glass for years.
- The friction stay on a new casement is set to the client's preferred restraint at handover — 45°, 90°, or fully open.

What we typically find on patio doors surveys around here
- ·The friction hinge on one window sticks at 45° open and needs the palm of a hand to nudge past.
- ·The window opens fine on a cold morning and binds by 3pm on a hot afternoon — classic thermal-expansion bind.
- ·The hinges are all dropped one notch from level, taking the sash out of square against the outer frame.
- ·Original security stickers from the installer are still on the bottom of the panes, twenty years later.
- ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
- ·One sash locks by lifting a nail out of the frame — a bodge from a decade ago that everyone forgot about.
- ·The multipoint lock still throws but the internal handle has 40° of dead travel before engaging.
- ·The composite front door skin has a shallow dent from a delivery bike handlebar and it has ovalised the door.
- ·The bottom track on the sliding door has a build-up of grit that the rollers grind through every open cycle.
- ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
- ·The frame colour has gone chalky on the sun side and stayed factory white on the shaded elevation.
- ·The reveal internally has been skimmed over the old plaster edge, hiding a 6mm gap behind the architrave.
- ·One patio-door interlock has a bent alignment lug — the door jams shut half of the time.
- ·The frame reinforcement steel inside the outer frame has begun to rust and stain the internal white finish.
- ·The trickle-vent covers have been snapped off and taped over from inside.
- ·The glazing spacers between panes carry the visible desiccant snowfall that gives away a blown unit.
Why residents are booking patio doors right now
- ·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 owner wants the front door hardware to match a specific interior palette — brass, matt black, or brushed nickel.
- ·The homeowner is preparing to work from home permanently and wants the office quieter than the living room used to be.
- ·The resident does not want to be sold to — they want a survey, a written figure, and to be left to decide.
- ·The resident wants the front door to sound solid when it closes — a hollow slap does not read as secure.
- ·The buyer wants the porch to stay a porch and not turn into a mud room by function.
- ·The resident works from home and wants the neighbour's dog to stop being the loudest thing on every call.
- ·The owner wants a threshold that does not require a step for a mobility scooter to clear.
- ·The owner has watched a neighbour's crew leave debris behind and wants a written cleanup expectation on the quote.
- ·The customer wants a specific hardware colour to match a kitchen renovation booked six months out.
- ·The buyer wants the property to look owned rather than tenanted — the front door tells that story first.
- ·The buyer wants the frames to still look right in twenty years, not just at handover.
- ·The buyer is moving in with two dogs and needs a back door that will not degrade with claw scrape.
- ·There is a puppy in training and the sliding door onto the garden has to work with a paw against the glass.
- ·The owner is preparing the elevation for a specific street-photo listing and wants the finish to be photographable in raking morning light.
- ·The resident wants the letterbox to stop being a draught source without giving up daily post.
How our fitters actually do the work
- ·The mitre joins on any Georgian bar are picked to face the corner that is least visible from indoors.
- ·The letterplate is fitted with the internal flap set to close under its own weight without dragging.
- ·The frame reinforcing steel is confirmed inside the top rail before the transom fixing is chosen.
- ·The multipoint keeps get a smear of grease inside the pocket before the door is closed for the first time.
- ·The install team pull the fridge out for kitchen-window swaps only after checking the flooring can take the drag scuff.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The frame drainage caps face outward and are set proud enough that they don't clog with a season of rainwater.
- ·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 composite slab is not cut on site — if it does not fit, a new slab is ordered rather than trimmed.
- ·The bathroom obscure glass pattern is confirmed with a physical sample against the existing pane, not chosen from a brochure image.
- ·The old frame is removed by cutting the corners with a reciprocating saw rather than a lever bar that damages the reveal.
- ·The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·The frame is plumbed on two axes before the first fixing goes in — not one axis and then trusted.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
- ·The old broken glass is bagged in a labelled sack, not tipped loose into a general skip.
FAQs — patio doors in Caerphilly
Can patio doors handle wind-driven rain off the mountain ridge?+
Directly, yes — 10+ years on the rollers before service, 20+ on the frame. That matters in Caerphilly where wind-driven rain off the mountain ridge is the single most common reason people call us.
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 do commercial patio doors for sites near Pontygwindy Industrial Estate?+
Yes. We've worked across Pontygwindy Industrial Estate and Bedwas House Industrial Estate, supplying the same thermally broken aluminium or reinforced uPVC build we use on residential. Commercial quotes include site access notes and out-of-hours options.
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.
Do you fit patio doors across all of Caerphilly?+
Yes — we work across every CF83 postcode, from Bedwas through to Trethomas, and out as far as Machen. Easy in via the A469, and we're 10 minutes from the A470 for vans loaded with full-house glass.
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 patio doors
A door that needs lifting, shoving or a second attempt to lock is warning you before the gearbox fails completely.
A sliding door that fights you is nearly always rollers and track debris, not a dead door.
Most break-ins through glazed openings exploit the cylinder or the keeps, both of which are upgradeable in an afternoon.
French doors are a pair, so the fault is usually in how the two leaves meet rather than in either leaf on its own.
