What we typically find on casement windows surveys around here
- ·A weep vent that was factory-drilled has been over-painted three times and no longer clears water from the chamber.
- ·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.
- ·The garden gate side of the property gets no direct sun and the frames there look ten years newer than the fronts.
- ·The reveal internally has been skimmed over the old plaster edge, hiding a 6mm gap behind the architrave.
- ·Original beads have been over-painted so many times they no longer clip flush and rattle in a gust.
- ·The frame colour has gone chalky on the sun side and stayed factory white on the shaded elevation.
- ·A homemade timber threshold has been screwed to the concrete cill in front of the patio door.
- ·The multipoint deadbolt still throws but the top hook has stopped catching and no one has noticed for months.
- ·One handle turns freely through 180° with no engagement — a snapped internal cam.
- ·There is a paint bridge from the internal architrave to the frame that will crack the moment the new unit lifts out.
- ·There is a permanent green algal streak below the sill where water is bypassing the drip groove.
- ·The porch-roof lead flashing has been dropping water onto the head of the front door for years.
- ·The internal reveal architrave has been re-fixed with panel pins that have rusted and stained the paintwork.
- ·One sash sits proud of the frame by 2mm along the top rail — a factory manufacturing tolerance that never got addressed.
- ·The bottom track on the sliding door has a build-up of grit that the rollers grind through every open cycle.

How our fitters actually do the work
- ·The crew takes the old glass off site in a labelled sack that day, not a skip left on the drive.
- ·The old keys are collected and destroyed, not left in a bag on the drive.
- ·The multipoint gearbox is thrown by hand before the frame goes in — a factory fault at that point is a five-minute fix.
- ·The frame reinforcement is chosen for the wind load exposure of the elevation, not the smallest steel that fits.
- ·The finished elevation is photographed from the pavement and uploaded to the office job file as sign-off record.
- ·The frame drainage slots are checked and blown clear before the beads go in — a plugged slot fills the chamber.
- ·The crew calls the client at 5pm the day before to confirm arrival window and site access details.
- ·The old handles are offered to the client before being binned — sometimes a chrome D-handle finds a shed door life.
- ·The threshold has an EPDM strip continuous under the frame — not stitched together across the door width.
- ·The internal beads are numbered on removal so they return to the same corner they came from.
- ·The internal trim goes on with pin nails through the flange, not straight through the visible face.
- ·The composite door slab is inspected under torchlight for delamination before the hinges are fitted.
- ·The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.
- ·The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The client's Wi-Fi router near the door is checked for a signal drop after the composite slab is fitted — a rare case, but worth confirming.

Do you fit casement windows across all of Cardiff?+

Why replace the whole set rather than one-by-one in a Cardiff home?+
Because sticky old aluminium or timber casements that whistle in wind and won't hold open against a breeze 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 CF10.
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.
Will the house be secure overnight during a full replacement?+
Yes. Only one elevation is open at a time and every opening we start is finished, glazed and locked before we leave for the day.

A 20-minute call gets the survey on the diary.

Faults we fix before recommending casement windows
Fog between the panes means the sealed unit has failed — the glass can usually be swapped without touching the frame.
A draught is usually a compression problem — gasket, hinge or seal — long before it's a reason to replace the window.
Which face the water sits on tells you everything: inside is ventilation, between the panes is a failed unit, outside is normal physics.
Rot in the bottom rail is repairable; rot that has reached the joints and the cill usually isn't worth chasing.
