French doors fitted across Bargoed & CF81
If you're looking at French doors for a home in Bargoed, you're probably dealing with wind funnelling straight up the Rhymney valley against front elevations or solid stone walls with deep reveals that need careful making good — both common in the steeply stepped stone terraces climbing both sides of the Rhymney valley, with small pockets of post war council built semis on the flatter ground at Gilfach and Aberbargoed you find across CF81. We've fitted hundreds of sets across Gilfach, Aberbargoed and Brithdir, all signed off under Caerphilly County Borough Council building standards. Outward-opening pairs suit narrow Cardiff and Barry gardens where inward swing would eat the room; inward pairs work well on Valleys terraces with paved patios.

Owner occupiers replacing one door or one window
Who this page is for: owner occupiers replacing one door or one window in Bargoed
A single replacement is a half day job for us and a whole day of your time, so the useful detail is arrival window, how the old frame comes out, and how the new one is made good inside and out.
Where this job stands or falls
- The old unit removed and taken away the same day
- Making good inside so there is no decorating job left behind
- The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.
- The bay assembly is squared with a laser diagonal, not a tape measure and eye.
The same ten year product guarantee applies whether you buy one unit or twenty

What we typically find on French doors surveys around here
- ·Every south-facing frame has visible micro-cracking in the surface film — early sign of UV embrittlement.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·The gasket join at the bottom corner has separated by a few millimetres — that's where the draught is coming from.
- ·The friction stays are the wrong hand for the sash — a previous swap fitted left-hand stays on a right-hand window.
- ·The mid-rail on the composite door is bowed outward at the middle by 2mm — a slab-warp symptom.
- ·The internal glazing bead sits proud of the frame by 1.5mm, so the seal at the top corner has failed first.
- ·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 composite door slab has a hairline crack along the letterplate cut-out from a delivery boot.
- ·The internal reveal plaster is spalling under the cill where condensation has run for years.
- ·The multipoint gearbox on the front door still throws, but the hooks miss the keeps by 2mm on the middle throw.
- ·The trickle-vent screw covers are missing and the internal chamber has filled with cobweb.
- ·The bottom hinge on the front door has torn its top screw fixing free of the frame.
- ·The old timber sub-frame under the current uPVC unit is still in place and is soft at the bottom left corner.
- ·The sealed unit is a 20mm gap, not the modern 28mm minimum, so U-values are into the mid-2s at best.
- ·The gap under the front door has been carpet-strip filled from inside — the exterior weather bar is missing.
- ·One sash locks by lifting a nail out of the frame — a bodge from a decade ago that everyone forgot about.
Why residents are booking French doors right now
- ·The owner wants the job to finish clean — no leftover offcuts in the skip on the drive, no sealant on the render.
- ·The buyer wants the front door delivered pre-hung and pre-glazed on the same date as the frames.
- ·The buyer wants the frames to still look right in twenty years, not just at handover.
- ·The customer wants a specific hardware colour to match a kitchen renovation booked six months out.
- ·The resident wants the crew to be locals who won't disappear if a warranty call needs answering in year eight.
- ·The current front door leaks visibly around the letterplate every time the wind swings east.
- ·The resident wants an installer who will point out things the current property is doing well and leave those alone.
- ·The resident does not want to be sold to — they want a survey, a written figure, and to be left to decide.
- ·The resident is moving elderly parents in downstairs and needs the front threshold to be wheelchair-usable.
- ·The resident has a shift-worker sleeping in the day and needs the bedroom to be a genuine acoustic step change.
- ·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 noise of the school run down and the light from the morning sun up.
- ·The owner has scaffolding booked for a re-render and wants the frames sequenced around the render trades.
- ·The buyer wants no upsell scripts — a survey, a spec, a figure, and space to think.
- ·The resident wants the front door to sound solid when it closes — a hollow slap does not read as secure.
- ·The homeowner wants matt black hardware because everything inside the house is matt black — no chrome to argue with.
How our fitters actually do the work
- ·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
- ·The multipoint hooks are lightly greased after fitting, before the door is closed for the first time.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The perimeter airtight tape is applied over the frame flange in a single unbroken run around all four sides.
- ·The frame is protected with a low-tack film across any face a tool might touch during the fitting hour.
- ·The composite door slab is inspected under torchlight for delamination before the hinges are fitted.
- ·The lock cylinder is measured for internal and external protrusion — a cylinder that stands proud is a snap risk.
- ·The window boards are pre-treated on the underside with a moisture seal before setting in place.
- ·The internal cill is scribed to the reveal, not just butted and caulked over the gap.
- ·The fitting van is stocked with the specific spare parts likely to be needed on the day — not a return trip on a missing hinge.
- ·The bathroom obscure glass pattern is confirmed with a physical sample against the existing pane, not chosen from a brochure image.
- ·The install date is stamped inside the frame chamber for future reference — a decade later a client can still date it.
- ·Any dropped hinges on the existing door are noted before the swap so the new frame is set for the correct drop.
- ·The frame drainage caps are proven flowing before the beading goes in — a bottle of water down the outer chamber.
- ·The client is walked through the finished job with a printed operation card, not a rushed verbal handover.
- ·The bay-corner post is set with a laser level across both faces before the outer frames are trimmed to fit.
FAQs — French doors in Bargoed
Will French doors suit the older steeply stepped stone terraces climbing both sides of the Rhymney valley common around Bargoed?+
Outward-opening pairs suit narrow Cardiff and Barry gardens where inward swing would eat the room; inward pairs work well on Valleys terraces with paved patios. We've installed dozens in Gilfach and Aberbargoed alone.
Why replace the whole set rather than one-by-one in a Bargoed home?+
Because a small back door that blocks the view of the garden and only opens one way 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 CF81.
How do you reach jobs in Bargoed from your base?+
Straight up the A469 from Caerphilly, and we book Bargoed streets together so the van only needs one parking spot per day — typically a short run via A469.
Can French doors handle wind funnelling straight up the Rhymney valley against front elevations?+
Directly, yes — 20+ years on the frame, 10-year hinge life before service. That matters in Bargoed where wind funnelling straight up the Rhymney valley against front elevations is the single most common reason people call us.
What colours and finishes are available for French doors?+
outward or inward-opening pairs; matching sidelights and top-lights available; white, anthracite, cream or dual-colour. We bring physical samples to the quote so you can see them against your steeply stepped stone terraces climbing both sides of the Rhymney valley in real light.
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.
Is it cheaper to repair the existing frame?+
Often, yes. Hinges, handles, gearboxes and single sealed units can all be replaced without touching the frame. We quote the repair first when the frame itself is sound.

Faults we fix before recommending French doors
A door that needs lifting, shoving or a second attempt to lock is warning you before the gearbox fails completely.
A composite slab that catches on the frame has almost always moved at the hinges, and hinges are adjustable in three planes.
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.
