Aluminium Windows

Aluminium Windows in Ystrad Mynach

For commuters using the Rhymney line into Cardiff, growing families in post war semis, and buyers on the newer Penallta developments in Ystrad Mynach, aluminium windows aren't a vanity upgrade — they're the single biggest fix for draughty original 1960s semi glazing on exposed corner plots. We supply matt anthracite (RAL 7016) as standard, with jet black on request. 30+ year frame life with a powder coat that doesn't chalk or fade like cheap PVC foil, which matters when the next Tredomen Business Park car park gets built and your elevation faces it head-on.

What we typically find on aluminium windows surveys around here

·The internal reveal plaster is spalling under the cill where condensation has run for years.
·The gap under the front door has been carpet-strip filled from inside — the exterior weather bar is missing.
·The georgian bar between the panes has come detached from the top spacer on one unit.
·The cill drainage caps on a north-facing elevation are frozen in place with layered moss.
·The old aluminium sliding door has grit in the track that has worn the roller wheels to elliptical.
·The gasket at the vent has perished and pulled away from its channel in two-inch sections.
·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
·The Yale night-latch on top of the multipoint is a sign the resident does not trust the primary lock.
·One kitchen unit has a defrost trace across the low-e coating — the argon fill has been gone a while.
·Every kitchen window handle has been replaced twice in ten years — a sign the espag is going, not just the handle.
·The window boards inside are chipboard, swollen at the edges from years of trickle condensation.
·The letterbox opening is not draught-proofed at all — a candle held two feet away flickers in a light wind.
·The front-door hinge screws are 25mm chipboard fixings, not the manufacturer's 60mm hinge screws.
·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.
·A cat flap has been cut through the lower panel of the back door, weakening the panel and voiding warranty.

Why residents are booking aluminium windows right now

·The buyer has just moved in and is fixing everything the vendor's homebuyer report flagged, in priority order.
·The buyer wants the sound of the sea audible but the wind noise gone.
·The homeowner wants the property EPC to move up a band ahead of a remortgage in six months.
·The resident does not want to be sold to — they want a survey, a written figure, and to be left to decide.
·The customer wants a specific hardware colour to match a kitchen renovation booked six months out.
·The homeowner has watched the neighbour's job go in and knows exactly what they do and do not want.
·The buyer wants the frames to still look right in twenty years, not just at handover.
·The buyer wants the property to look owned rather than tenanted — the front door tells that story first.
·The homeowner is on holiday half the year and wants a security spec they can leave for weeks without worrying.
·The homeowner wants a single date, a single crew, and a single guarantee — not a paper trail across three companies.
·The buyer wants the porch to stay a porch and not turn into a mud room by function.
·The buyer wants a composite door slab that a courier's boot cannot dent when a delivery is fumbled.
·The buyer wants a full set of the same colour across every elevation, not the current mixed collection.
·The homeowner is expecting twins and wants the room-to-room noise transfer down before the arrival.
·The buyer wants a specific coloured composite front door because they saw it three doors down and it made the street.
·The owner wants the property to look ten years newer without needing an extension.

How our fitters actually do the work

·Any dropped hinges on the existing door are noted before the swap so the new frame is set for the correct drop.
·The lead fitter leaves a handwritten note of anything the client should watch in the first month, not a printed generic checklist.
·The client's paint colour is sampled at the survey visit and matched at the office before the fitters arrive on install day.
·The old frame comes out in one piece where possible so the reveal detail is not chased through with a demolition bar.
·The reveals are photographed on arrival so any pre-existing damage is on record before the crew touches them.
·Every silicone bead is tooled with the correct radius spatula, not smoothed with a wet finger only.
·Ground protection sheet goes down before the old frame comes out — not after the mess starts.
·The friction stay screws are torque-limited, not driven at full trigger — over-driven screws strip the stay chamber.
·The crew takes the old glass off site in a labelled sack that day, not a skip left on the drive.
·The door is closed, locked, and left overnight before final adjustment, so any settlement is captured before sign-off.
·The frame perimeter is checked with a smoke pencil for airtightness before the internal trims go on.
·The crew asks the client where the kettle lives before they set up so tea gets made rather than negotiated.
·The frame is plumbed on two axes before the first fixing goes in — not one axis and then trusted.
·The composite door slab is inspected under torchlight for delamination before the hinges are fitted.
·The lead fitter photographs the reveal condition before the old frame comes out and shares those photos with the office.
·The perimeter tape between frame and reveal is a compressible foam tape, not a plain butyl strip.
