New flush sash windows for Bargoed homes
Most of our flush sash windows jobs in Bargoed start with the same call: "modern chamfered casements looking out of place on a period stone cottage or Edwardian bay". Around here that usually means a steeply stepped stone terraces climbing both sides of the Rhymney valley where the original frames have given up. We work right across CF81 — Gilfach, Aberbargoed, Brithdir and the surrounding streets — typically arriving via A469. Old timber or uPVC frames removed with care to protect the reveal, flush frames sat proud of the brick line to sit level with render or cladding, drainage slots angled below the cill.

Owner occupiers replacing one door or one window
Buying flush sash windows as owner occupiers replacing one door or one window
This page is for the single replacement, not the whole property. One failed unit, one tired front door, one window that never closed properly since the last fitter left. The job is small, so the things that matter are turning up when promised and leaving the reveal tidy.
The things worth checking before you accept a price
- A fixed price for one opening with no minimum order pressure
- The old unit removed and taken away the same day
- The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
- Trickle vents are drilled through the outer frame with a bespoke jig — not freehand with a spade bit.
The same ten year product guarantee applies whether you buy one unit or twenty

What we typically find on flush sash windows surveys around here
- ·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
- ·Two units have the classic dust ring inside the sealed gap, meaning the perimeter seal has been breached for at least a year.
- ·The glazing spacer bars are aluminium, not warm-edge — a decade behind current U-value expectation.
- ·The georgian bar between panes on one unit has slipped off its top spacer and is sitting diagonally inside the sealed cavity.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
- ·A homemade timber threshold has been screwed to the concrete cill in front of the patio door.
- ·The gap under the front door has been carpet-strip filled from inside — the exterior weather bar is missing.
- ·The internal beads pop out with a chisel and a tap, but the external glazing gasket is bonded solidly to the frame.
- ·The trickle-vent screw covers are missing and the internal chamber has filled with cobweb.
- ·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 front door skin has a shallow dent from a delivery bike handlebar and it has ovalised the door.
- ·The old timber sub-cill under a uPVC swap is boron-treatable but only if we lift the frame off it cleanly.
- ·One casement's friction stay has been swapped for a random spare that doesn't match the arm geometry.
- ·Every kitchen window handle has been replaced twice in ten years — a sign the espag is going, not just the handle.
- ·The front door has been painted three times without stripping — the paint film is now stopping the door closing at the top.
- ·Every casement in the property opens with a firm tug on the second click — the friction stays are seized.
Why residents are booking flush sash windows right now

- ·The homeowner is planning a loft conversion next year and wants the windows sorted before scaffold cost is priced.
- ·The homeowner is expecting twins and wants the room-to-room noise transfer down before the arrival.
- ·The buyer wants a genuine step-up in security, not a marketing claim — PAS24 tested, not PAS24 marketed.
- ·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 resident is done with condensation-driven mould at the sill line every February.
- ·The homeowner has quotes from two national companies and wants a local one to be honest about the same job.
- ·There is a puppy in training and the sliding door onto the garden has to work with a paw against the glass.
- ·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 current front door leaks visibly around the letterplate every time the wind swings east.
- ·The resident wants the whole property warm to bare feet on a January morning — the frames are the last variable.
- ·The owner has scaffolding booked for a re-render and wants the frames sequenced around the render trades.
- ·The buyer wants the sound of the sea audible but the wind noise gone.
- ·The owner wants a threshold that does not require a step for a mobility scooter to clear.
- ·The homeowner is preparing to work from home permanently and wants the office quieter than the living room used to be.
- ·The homeowner is preparing the property for a smart-home installation and wants sensor pockets designed into the reveals.
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 bay assembly is squared with a laser diagonal, not a tape measure and eye.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The door hinges are set with the correct rise before the frame is finally fixed — retro-adjustment on cheap hinges is limited.
- ·The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·The bay-corner post gets a structural bracket into masonry, not a token fixing into the outer frame.
- ·The glass has a factory kite mark visible at handover — not scraped off by a lazy cleaner during the fitting hour.
- ·Ground protection sheet goes down before the old frame comes out — not after the mess starts.
- ·The old frame is removed by cutting the corners with a reciprocating saw rather than a lever bar that damages the reveal.
- ·The client is walked through the operation of every lock, every vent, and every restraint before the crew leaves.
- ·The bead-in tools are rubber-faced, not steel — a steel tool marks the profile within minutes.
- ·The composite slab is not cut on site — if it does not fit, a new slab is ordered rather than trimmed.
- ·The concrete cill under the frame is checked for cracks; a hairline gets a slurry fix before the frame is set.
- ·The old broken glass is bagged in a labelled sack, not tipped loose into a general skip.
- ·Fixings are always at the reinforcement points — a screw through the chamber alone loosens within a year.
