What we typically find on patio doors surveys around here
- ·The friction hinge on one window sticks at 45° open and needs the palm of a hand to nudge past.
- ·One sash locks by lifting a nail out of the frame — a bodge from a decade ago that everyone forgot about.
- ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
- ·The cill end-cap has fallen off and the cill chamber is now a home for insects.
- ·The trickle-vent screw covers are missing and the internal chamber has filled with cobweb.
- ·The concrete cill under the door has heaved by 3mm across the two-metre span, tilting the whole threshold.
- ·The composite slab has swelled by 2mm on the hinge stile from years of morning-sun exposure.
- ·The middle mullion sags visibly across the top rail on any window wider than 1.6m.
- ·The window opens fine on a cold morning and binds by 3pm on a hot afternoon — classic thermal-expansion bind.
- ·There is a hairline crack running diagonally from the top corner of one bathroom pane where the frame has twisted.
- ·A previous fitter drilled through the outer frame chamber for the trickle vent — never fully sealed the drilling.
- ·The old timber sub-cill under a uPVC swap is boron-treatable but only if we lift the frame off it cleanly.
- ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
- ·Two units have the classic dust ring inside the sealed gap, meaning the perimeter seal has been breached for at least a year.
- ·The internal reveal architrave has been re-fixed with panel pins that have rusted and stained the paintwork.
- ·Every south-facing frame has visible micro-cracking in the surface film — early sign of UV embrittlement.

How our fitters actually do the work
- ·The lead fitter leaves a handwritten note of anything the client should watch in the first month, not a printed generic checklist.
- ·The trickle vent chamber inside the frame is proven clear with a torch before the outer cap goes on.
- ·The head of the frame is packed dry before the sides are fixed, so the frame does not distort during installation.
- ·The screws through the outer frame go into pilot-drilled masonry, not driven with hammer action alone.
- ·The threshold is bedded on butyl mastic under the outer skin, giving the fitter a second waterproof line behind the perimeter silicone.
- ·The trim between the frame and the plaster line goes on last, after the sealant has set and been proven leak-tight.
- ·Cavity closers get inserted where the old frame's cavity closer has failed — not omitted because it is unseen work.
- ·The client is walked through the finished job with a printed operation card, not a rushed verbal handover.
- ·The old cylinder is disposed of by the crew, not left in a bag on the drive for the client to bin.
- ·The bay assembly is squared with a laser diagonal, not a tape measure and eye.
- ·The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
- ·The internal cill support is packed with hardwood the full depth of the cill, not just at the ends.
- ·The client is left with the manufacturer's paperwork in a labelled envelope, not a folded receipt tucked inside a drawer.
- ·The glazing bead is tapped in with a rubber mallet, not a metal claw — the profile marks otherwise.
- ·The old keys are collected and destroyed, not left in a bag on the drive.
- ·The frame is protected with a low-tack film across any face a tool might touch during the fitting hour.

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.
