Landlords, letting agents and portfolio owners
Why casement windows look different to landlords, letting agents and portfolio owners
For portfolio owners the question is usually which properties to do first. This page covers the specification we recommend for lets locally, and what the same spend does to an EPC band.
Where this job stands or falls
- Work scheduled inside a void period so rent is not lost
- Consistent specification across a portfolio so spares are interchangeable
- We de-glaze into a padded rack, not straight into the skip — the intact panes go to a glazier for reuse.
- The cylinder key gets a keyring immediately, so it does not sit unnoticed in a jacket pocket for the day.
Written guarantees and insurance documentation supplied for the property file as standard
What we typically find on casement windows surveys around here
- ·The threshold weather bar is missing its rubber blade — you can see daylight under the door.
- ·The frame reinforcement steel inside the outer frame has begun to rust and stain the internal white finish.
- ·Original security bolts on the ground floor sashes are seized in place and no longer key-lockable.
- ·The gasket at the vent has perished and pulled away from its channel in two-inch sections.
- ·Original door furniture is 90s brass, tarnished, and no longer matches anything else on the elevation.
- ·A tenant repair on the bathroom window has used bathroom silicone as the primary bead — it's already gone black.
- ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
- ·A previous owner has fitted a chain to the front door on top of the multipoint — a sign they never trusted the lock.
- ·The bay-corner post has bowed by about 4mm across two metres — visible only if you sight along it.
- ·Condensation runs down the inside of every north-facing pane between October and March.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·The letter plate cover has snapped off and the exposed brush strip has flattened over the years.
- ·The old aluminium sliding door has a cracked head roller that pulls the door out of parallel with the frame.
- ·The internal reveal plaster is spalling under the cill where condensation has run for years.
- ·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 old timber back door has a live rot pocket at the bottom hinge that reads soft to a screwdriver tip.
Why residents are booking casement windows right now
- ·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 front door to feel expensive to close — the weight, the sound, the drop of the latch.
- ·The owner is done with the sliding door drag and wants one that closes with a single push.
- ·The owner is buying and wants to time the frame swap for the week between exchange and moving in.
- ·The buyer wants the heating bill visibly lower before next winter, not a marginal improvement they have to guess at.
- ·The buyer wants a survey that says no to things when they don't fit, not just yes to everything they ask for.
- ·The homeowner wants a single date, a single crew, and a single guarantee — not a paper trail across three companies.
- ·The resident wants an installer who will point out things the current property is doing well and leave those alone.
- ·The homeowner is fine spending more if the crew is right — the price is the last question, not the first.
- ·The homeowner wants the back door to be a family door — kids in and out, and no one having to slam it to lock.
- ·The homeowner has just re-rendered the front elevation and wants the frames to be the last piece of the picture.
- ·There is a downstairs shower being fitted and the bathroom window needs to be swappable before the tiler starts.
- ·The resident wants an installer who will honestly say when a repair beats a replacement.
- ·The owner is done paying to service failing 90s uPVC every couple of years and wants the whole set replaced together.
- ·The homeowner has quotes for a new kitchen next spring and wants the patio doors in before those trades arrive.
- ·The resident wants the letterbox to stop being a draught source without giving up daily post.
How our fitters actually do the work
- ·The old handles are offered to the client before being binned — sometimes a chrome D-handle finds a shed door life.
- ·The keeps for the multipoint are set with the door open and the position marked, not adjusted by eye once the door is closed.
- ·The internal architrave is coped rather than mitred where the reveal wall is out of true.
- ·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.
- ·New frames sit on hardwood packers, not plastic offcuts — plastic creeps under load, timber does not.
- ·The letterplate cowl is checked to swing free without touching the door face — a rubbing cowl marks the paint within weeks.
- ·The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
- ·The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
- ·Every silicone bead is tooled with the correct radius spatula, not smoothed with a wet finger only.
- ·The frame reinforcing steel is confirmed inside the top rail before the transom fixing is chosen.
- ·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 old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·The keeps for the multipoint are set with a strike plate template, not marked by eye against the closed door.
- ·Cylinders come out of the box, get numbered, and are the last thing fitted, so a lost cylinder does not stall the day.

Do you do commercial casement windows for sites near Ffrwdgrech Industrial Estate?+

Summary — casement windows in Brecon
Sticky old aluminium or timber casements that whistle in wind and won't hold open against a breeze won't fix itself, and putting it off through another winter in Brecon just costs more in heating, particularly with exposed hillside wind and freeze-thaw on single-skin stone walls working on the elevation every week. A 20-minute call gets the survey on the diary. On casement windows specifically: sticky old aluminium or timber casements that whistle in wind and won't hold open against a breeze, 1 window in 90 minutes, full-house in 1–3 days, 10-year product, 2-year fitting, lifetime hardware servicing.
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.
