New patio doors for Brecon homes

Owner occupiers replacing one door or one window
Buying patio doors 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.
Where this job stands or falls
- A fixed price for one opening with no minimum order pressure
- The old unit removed and taken away the same day
- The frame drainage caps face outward and are set proud enough that they don't clog with a season of rainwater.
- The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.

What we typically find on patio doors surveys around here
- ·The friction stays are the wrong hand for the sash — a previous swap fitted left-hand stays on a right-hand window.
- ·The internal window board has swelled at the sink end from years of splash and is delaminating along the front edge.
- ·The frame drainage slots at the bottom are clogged with debris, so rainwater sits inside the chamber.
- ·The cill drainage caps on a north-facing elevation are frozen in place with layered moss.
- ·The old timber back door has a live rot pocket at the bottom hinge that reads soft to a screwdriver tip.
- ·The internal beads pop out with a chisel and a tap, but the external glazing gasket is bonded solidly to the frame.
- ·The old aluminium sliding door has grit in the track that has worn the roller wheels to elliptical.
- ·The glazing spacers between panes carry the visible desiccant snowfall that gives away a blown unit.
- ·Trickle vents on the older units are 4000mm² each — modern regs would spec 8000mm² for the same room.
- ·The georgian bar between the panes has come detached from the top spacer on one unit.
- ·The reinforcement steel inside the top rail of a wide sash has rusted through in one corner.
- ·The frame reinforcement steel inside the outer frame has begun to rust and stain the internal white finish.
- ·One kitchen unit has a defrost trace across the low-e coating — the argon fill has been gone a while.
- ·The transom bar has a live crack in the plastic, opened up by summer expansion cycles.
- ·A previous fitter foam-filled the reveal gap directly against the frame, and the foam has now pushed the jamb inward.
- ·The sealed unit is a 20mm gap, not the modern 28mm minimum, so U-values are into the mid-2s at best.
Why residents are booking patio doors right now
- ·The buyer is running a small business from the home office and wants the kerb to say established and settled.
- ·The buyer wants the heating bill visibly lower before next winter, not a marginal improvement they have to guess at.
- ·The buyer wants a genuine step-up in security, not a marketing claim — PAS24 tested, not PAS24 marketed.
- ·The resident wants the front door lock to be re-keyable if a set of keys goes missing in year three.
- ·The owner wants the property to look ten years newer without needing an extension.
- ·The homeowner has just re-rendered the front elevation and wants the frames to be the last piece of the picture.
- ·The resident wants the frames to survive a specific paint colour on the render for at least a decade.
- ·The resident wants the letterbox to stop being a draught source without giving up daily post.
- ·The owner has an ageing parent visiting for extended stays and wants the guest bedroom warmer than it currently is.
- ·The resident wants the sliding door to open with a fingertip after ten years of use, not two hands after two.
- ·A newborn has arrived and the parents want the nursery to hold a stable overnight temperature.
- ·The owner is having a kitchen refit next month and wants the patio door in first so the tiler works to a fitted threshold.
- ·The homeowner has quotes from two national companies and wants a local one to be honest about the same job.
- ·The owner wants the job to finish clean — no leftover offcuts in the skip on the drive, no sealant on the render.
- ·The owner has tried draught-excluder tape and a chimney balloon and now accepts the frames themselves are the cause.
- ·The homeowner is on a smart meter and can see the room-by-room heat loss on a phone app.
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 keys are handed to the client only after the lock has been thrown four times in and out from both sides.
- ·The friction stay on a new casement is set to the client's preferred restraint at handover — 45°, 90°, or fully open.
- ·The screws through the outer frame go into pilot-drilled masonry, not driven with hammer action alone.
- ·The trickle vent chamber inside the frame is proven clear with a torch before the outer cap goes on.
- ·Fixings are set at the manufacturer's spacing, not evenly spaced by eye — the corner loads matter.
- ·The threshold ramp on an accessible door is set to a maximum 15mm rise and confirmed with a spirit-level lip.
- ·The internal cill is scribed to the reveal, not just butted and caulked over the gap.
- ·The internal make-good uses caulk to the plaster, silicone to the tiles, and neither where paint has to go over.
- ·Sealant is a single continuous bead run at the perimeter, not overlapped in six-inch runs.
- ·Ground protection sheet goes down before the old frame comes out — not after the mess starts.
- ·The install team pull the fridge out for kitchen-window swaps only after checking the flooring can take the drag scuff.
- ·The door is closed, locked, and left overnight before final adjustment, so any settlement is captured before sign-off.
- ·We de-glaze into a padded rack, not straight into the skip — the intact panes go to a glazier for reuse.
- ·The internal reveal is masked before any silicone runs, so the finished bead is a clean line against the plaster.
- ·The old debris leaves in a single tidy load — not skip visits three days apart.

Will patio doors suit the older Georgian and Victorian stone houses in the town centre common around Brecon?+

How long does a patio doors install take in a Brecon property?+
Single day for a 2-panel slider, 1–2 days for French sets. Most of the Georgian and Victorian stone houses in the town centre we see in Brecon fit our standard schedule with no surprises.
Why replace the whole set rather than one-by-one in a Brecon home?+
Because tired 80s sliding aluminium doors that stick, lose heat and rattle in the wind 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 LD3.
Do you take on single window or single door jobs?+
Yes, and there is no minimum order. A single opening is usually a half day, including removing the old frame and making the reveal good inside and out.
Will one new unit match the older frames already fitted?+
We match profile, colour and hardware finish as closely as the current stock lines allow, and we will tell you honestly at survey where an exact match is not possible.

Faults we fix before recommending patio doors
A door that needs lifting, shoving or a second attempt to lock is warning you before the gearbox fails completely.
A sliding door that fights you is nearly always rollers and track debris, not a dead door.
Most break-ins through glazed openings exploit the cylinder or the keeps, both of which are upgradeable in an afternoon.
French doors are a pair, so the fault is usually in how the two leaves meet rather than in either leaf on its own.
