New build, extension and self build projects
Buying patio doors as new build, extension and self build projects
For projects still on paper, this page explains what we need from the drawings, what lead times look like, and how glazing is coordinated with the rest of the programme.
What we build into the quote for you
- Structural opening sizes agreed and issued to the builder in writing
- Thermal performance figures for the SAP or Part L calculation
- The gasket wedges are trimmed with a fresh knife blade for every unit — a dull blade tears the EPDM.
- The frame is plumbed on two axes before the first fixing goes in — not one axis and then trusted.
Extension and garden room glazing completed to the builder's programme, with sizes issued before brickwork started

What we typically find on patio doors surveys around here
- ·The stay arm on the top vent has bent and no longer sits into its rest bracket cleanly.
- ·One patio-door interlock has a bent alignment lug — the door jams shut half of the time.
- ·A weep vent that was factory-drilled has been over-painted three times and no longer clears water from the chamber.
- ·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 door-side glazed sidelight has a shattered internal pane held together by the laminated interlayer.
- ·The bathroom obscure glass pattern has been discontinued for over a decade — matching a single pane is not possible.
- ·The bottom rail on the sash has taken years of rain runoff and swollen enough to bind on the frame.
- ·The multipoint keeps have worn a shallow groove where the hooks now catch — closing needs a lift-and-pull.
- ·The porch canopy has been leaking directly onto the top of the door for years — the top edge of the slab is soft.
- ·The bay-window front elevation has a visible smile — the middle mullion has sagged and taken the head with it.
- ·The letterplate flap spring has gone slack and the flap now hangs open in a light breeze.
- ·The multipoint deadbolt still throws but the top hook has stopped catching and no one has noticed for months.
- ·Every casement in the property opens with a firm tug on the second click — the friction stays are seized.
- ·The multipoint gearbox on the front door still throws, but the hooks miss the keeps by 2mm on the middle throw.
- ·One of the sealed units carries the previous installer's phone number etched on the aluminium spacer bar.
- ·A homemade timber threshold has been screwed to the concrete cill in front of the patio door.
Why residents are booking patio doors right now
- ·The homeowner is planning a garden studio and wants the patio doors to bookend the view when it's finished.
- ·The buyer wants a specific coloured composite front door because they saw it three doors down and it made the street.
- ·The buyer wants the whole job done by one team who own the outcome — not designed in one place and fitted in another.
- ·The resident wants the ground-floor windows to be genuinely secure — laminated inner pane, PAS24 hardware, real not marketed.
- ·The homeowner has quotes for a new kitchen next spring and wants the patio doors in before those trades arrive.
- ·There is a puppy in training and the sliding door onto the garden has to work with a paw against the glass.
- ·The homeowner is on a smart meter and can see the room-by-room heat loss on a phone app.
- ·The buyer is moving in with two dogs and needs a back door that will not degrade with claw scrape.
- ·The owner has tried draught-excluder tape and a chimney balloon and now accepts the frames themselves are the cause.
- ·The owner wants the frames to disappear visually and let the view do the work.
- ·The buyer wants the frames to still look right in twenty years, not just at handover.
- ·The owner wants the property to look ten years newer without needing an extension.
- ·The resident wants the crew to remove and re-hang the internal curtains as part of the job, not leave that step to them.
- ·The owner has scaffolding booked for a re-render and wants the frames sequenced around the render trades.
- ·The buyer wants no upsell scripts — a survey, a spec, a figure, and space to think.
- ·The buyer wants the whole ground floor to feel more connected to the garden without losing the wall.
How our fitters actually do the work
- ·The internal beads are numbered on removal so they return to the same corner they came from.
- ·The fitting van is stocked with the specific spare parts likely to be needed on the day — not a return trip on a missing hinge.
- ·The concrete cill under the frame is checked for cracks; a hairline gets a slurry fix before the frame is set.
- ·The old frame's fixing holes in the brick are filled and made good before the new outer frame beads up to the reveal.
- ·The bay-corner post gets a structural bracket into masonry, not a token fixing into the outer frame.
- ·The multipoint keeps get a smear of grease inside the pocket before the door is closed for the first time.
- ·Foam gets a wet finger dressed into the internal reveal, not a dry-cut strip that pulls back later.
- ·The wall around the frame is Hoovered before the client sees the room again — brick dust ages a first impression.
- ·The new frame is stood in the reveal dry before any fixings go in — a final chance to catch a wrong-hand delivery.
- ·The internal make-good uses caulk to the plaster, silicone to the tiles, and neither where paint has to go over.
- ·The bay assembly is squared with a laser diagonal, not a tape measure and eye.
- ·The crew calls the client at 5pm the day before to confirm arrival window and site access details.
- ·The bead-in tools are rubber-faced, not steel — a steel tool marks the profile within minutes.
- ·Every silicone bead is tooled with the correct radius spatula, not smoothed with a wet finger only.
- ·The keeps for the multipoint are set with a strike plate template, not marked by eye against the closed door.
- ·The multipoint gearbox is thrown by hand before the frame goes in — a factory fault at that point is a five-minute fix.

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.
