Bargoed full-house replacement — survey, supply & install
Bargoed sits 4 miles from Ystrad Mynach and 5 from Blackwood, and that's the patch this page covers. The full house window & door replacement we fit here use A+ uPVC or aluminium frames and argon-filled units, which is what holds up against steeply sloping streets that limit where a van can park to unload glass. Straight up the A469 from Caerphilly, and we book Bargoed streets together so the van only needs one parking spot per day, so site visits and follow-ups don't drag.

Owners of older and character property
Owners of older and character property around Bargoed: what changes
Written for character property owners. The concern is rarely thermal performance alone, it is whether a modern frame will make the elevation look wrong from the pavement.
The things worth checking before you accept a price
- Heritage colours and traditional hardware rather than stock white and chrome
- Careful removal so stone and render around the opening is not damaged
- New frames sit on hardwood packers, not plastic offcuts — plastic creeps under load, timber does not.
- The old debris leaves in a single tidy load — not skip visits three days apart.
Completed work on older terraces and character stock where the elevation still reads correctly from the street
What we typically find on full-house replacement surveys around here
- ·The outer frame has moved fractionally over the years, dropping the bottom hinge screw pattern out of line.
- ·The garden gate side of the property gets no direct sun and the frames there look ten years newer than the fronts.
- ·The cylinder on the front door still has the builder's key stamp, meaning it has never been changed since handover.
- ·Original door furniture is 90s brass, tarnished, and no longer matches anything else on the elevation.
- ·The georgian bar between panes on one unit has slipped off its top spacer and is sitting diagonally inside the sealed cavity.
- ·The internal window board has swelled at the sink end from years of splash and is delaminating along the front edge.
- ·The mid-rail on the composite door is bowed outward at the middle by 2mm — a slab-warp symptom.
- ·The gasket join at the bottom corner has separated by a few millimetres — that's where the draught is coming from.
- ·The frame drainage on a south-facing bathroom window is blocked with paint film from the exterior repaint.
- ·Every south-facing frame has visible micro-cracking in the surface film — early sign of UV embrittlement.
- ·A previous fitter left the transport wedges in the frame corners and the internal seal never fully reset.
- ·The middle mullion sags visibly across the top rail on any window wider than 1.6m.
- ·The internal beadwork has been painted so many times the mitres are unrecognisable.
- ·The old timber sub-cill under a uPVC swap is boron-treatable but only if we lift the frame off it cleanly.
- ·The old aluminium sliding door has a cracked head roller that pulls the door out of parallel with the frame.
- ·The letterplate is a straight through-plate with no anti-snap flap — visible from outside in the hallway.
Why residents are booking full-house replacement right now
- ·The owner has an electric car on the drive and wants the front to say the whole property has been kept up.
- ·The resident is expecting an elderly parent to move in and needs a door that opens without a shove.
- ·The homeowner is on a smart meter and can see the room-by-room heat loss on a phone app.
- ·The buyer is buying the property specifically for the garden and wants a bi-fold that opens the whole rear elevation.
- ·The owner wants the master bedroom quiet enough for a night-shift partner to sleep past 11am.
- ·The owner is done with the sliding door drag and wants one that closes with a single push.
- ·The homeowner has watched the neighbour's job go in and knows exactly what they do and do not want.
- ·The homeowner is selling within eighteen months and wants the front elevation to photograph well for the listing.
- ·The resident wants the letterbox to stop being a draught source without giving up daily post.
- ·The resident is done with condensation-driven mould at the sill line every February.
- ·The homeowner wants a five-star Checkatrade installer at the door, not a subcontracted crew nobody has vetted.
- ·The buyer is done with the sound of the frames rattling in a gale.
- ·The buyer is furnishing the property for short-term let and wants a five-year cosmetic warranty on the door slab.
- ·The resident wants the front door to sound solid when it closes — a hollow slap does not read as secure.
- ·The owner has tried draught-excluder tape and a chimney balloon and now accepts the frames themselves are the cause.
- ·The owner wants the front door to feel expensive to close — the weight, the sound, the drop of the latch.
How our fitters actually do the work
- ·Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
- ·The perimeter airtight tape is applied over the frame flange in a single unbroken run around all four sides.
- ·The gasket at the corner mitre is butt-jointed with a fresh knife cut, not stretched and hoped.
- ·The frame drainage caps are proven flowing before the beading goes in — a bottle of water down the outer chamber.
- ·The threshold sealant runs the full width with a single tool pass, not stitched together in inches.
- ·Cavity closers get inserted where the old frame's cavity closer has failed — not omitted because it is unseen work.
- ·Door thresholds are set with a spirit level along their full length and then re-checked with a straight edge.
- ·The lead fitter photographs the reveal condition before the old frame comes out and shares those photos with the office.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·The multipoint gearbox is thrown by hand before the frame goes in — a factory fault at that point is a five-minute fix.
- ·The door is closed, locked, and left overnight before final adjustment, so any settlement is captured before sign-off.
- ·The bay-corner post gets a structural bracket into masonry, not a token fixing into the outer frame.
- ·The client's alarm sensors on the old frames are removed and returned to the client, not binned by default.
- ·The composite door slab is inspected under torchlight for delamination before the hinges are fitted.
- ·The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
- ·The door hinges are set with the correct rise before the frame is finally fixed — retro-adjustment on cheap hinges is limited.
FAQs — full-house replacement in Bargoed
Can full-house replacement handle wind funnelling straight up the Rhymney valley against front elevations?+
Directly, yes — whole property reset to a-rated thermal performance for a 20-year horizon. That matters in Bargoed where wind funnelling straight up the Rhymney valley against front elevations is the single most common reason people call us.
Do you fit full-house replacement across all of Bargoed?+
Yes — we work across every CF81 postcode, from Gilfach through to Aberbargoed, and out as far as Brithdir. Straight up the A469 from Caerphilly, and we book Bargoed streets together so the van only needs one parking spot per day.
Why replace the whole set rather than one-by-one in a Bargoed 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 CF81.
Do you do commercial full-house replacement for sites near Bargoed Business Park?+
Yes. We've worked across Bargoed Business Park and the Hanbury Road retail area, supplying the same A+ uPVC or aluminium frames build we use on residential. Commercial quotes include site access notes and out-of-hours options.
What guarantee do I get when you fit full-house replacement in Bargoed?+
10-year product on every frame, 2-year fitting on the whole package, single point of contact. We're insured to work right across Caerphilly County Borough Council's area, and you have one named contact from quote to snag.
Can original glazing bar patterns be matched?+
In most cases, using astragal bars externally or bars within the sealed unit. We will show you both at survey because they look noticeably different from the pavement.
Do I need permission to replace windows on a character property?+
Usually not on an unlisted house outside a conservation area. Inside one, or where an article 4 direction applies, the rules are stricter and we will check with the council before you order.
Check the constraints first in Bargoed
We will tell you where conservation area rules or an article 4 direction affect what can be fitted before you spend anything. Full-house replacement for Bargoed and the Caerphilly County Borough Council area, typically 2–4 days depending on count, with a final snag visit a week later, with a written price inside 24 hours.
Summary — full-house replacement in Bargoed
From Gilfach to Brithdir, our patch is small enough that we'll see your finished full-house replacement install ten times a year. That keeps us honest around Bargoed. Get in touch when you're ready.

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.
