Written for commercial premises, offices and managed sites
Written for offices, units and managed premises. The job is priced on access and downtime as much as on the glazing itself, so this page sets out how we work around a trading business.
Where this job stands or falls
- Working outside trading hours where the premises cannot close
- One invoice with a purchase order reference for the finance team
- The install team pull the fridge out for kitchen-window swaps only after checking the flooring can take the drag scuff.
- Foam gets a wet finger dressed into the internal reveal, not a dry-cut strip that pulls back later.
Work completed on trading premises out of hours, with the unit open as normal the next morning

What we typically find on garage doors surveys around here
- ·The georgian bar between panes on one unit has slipped off its top spacer and is sitting diagonally inside the sealed cavity.
- ·A previous decorator's dust sheet was left inside the frame chamber during a repaint and is still there.
- ·The internal window board has swelled at the sink end from years of splash and is delaminating along the front edge.
- ·A previous fitter drilled through the outer frame chamber for the trickle vent — never fully sealed the drilling.
- ·The friction hinge on a bedroom window has one detent — it either opens fully or slams shut on any breeze.
- ·The bathroom obscure glass pattern has been discontinued for over a decade — matching a single pane is not possible.
- ·The seal at the beading corner has shrunk enough to expose the mitre on the internal white finish.
- ·There is a permanent green algal streak below the sill where water is bypassing the drip groove.
- ·One sash sits proud of the frame by 2mm along the top rail — a factory manufacturing tolerance that never got addressed.
- ·The concrete cill under the door has heaved by 3mm across the two-metre span, tilting the whole threshold.
- ·Silicone at the outer perimeter has hardened, cracked, and lifted at the head — water tracks behind it in heavy rain.
- ·The old timber sub-frame under the current uPVC unit is still in place and is soft at the bottom left corner.
- ·Wet-set fixings through the outer frame have rusted and stained the surrounding brick.
- ·A previous cylinder swap left the escutcheon plate rotating freely — a snap risk that nobody logged.
- ·The bathroom pane is patterned glass from the original build, and the pattern is no longer a current stock line.
- ·The transom bar has a live crack in the plastic, opened up by summer expansion cycles.

- ·The owner is done with the annual condensation season and wants the fabric of the openings to end it.
- ·The owner is preparing the elevation for a specific street-photo listing and wants the finish to be photographable in raking morning light.
- ·The owner wants the crew to talk to the neighbour before scaffold goes up on a shared party wall.
- ·The resident wants the noise of the school run down and the light from the morning sun up.
- ·The resident works from home and wants the neighbour's dog to stop being the loudest thing on every call.
- ·The homeowner wants the front porch to feel enclosed in winter and open in summer.
- ·The homeowner has just re-rendered the front elevation and wants the frames to be the last piece of the picture.
- ·A recent break-in on the street has moved security up the priority list ahead of aesthetics.

How our fitters actually do the work
- ·The door slab gets a full inspection before hanging — dents, delamination, edge integrity, all noted before fixings go through.
- ·The glazing bead is tapped in with a rubber mallet, not a metal claw — the profile marks otherwise.
- ·The crew asks the client where the kettle lives before they set up so tea gets made rather than negotiated.
- ·The perimeter foam goes in in two passes so the second lift meets the first without a void in the middle.
- ·The door hinges are set with the correct rise before the frame is finally fixed — retro-adjustment on cheap hinges is limited.
- ·The install team pull the fridge out for kitchen-window swaps only after checking the flooring can take the drag scuff.
- ·The lock cylinder is measured to sit flush with the escutcheon plate — a proud cylinder is a snap risk.
- ·The crew photographs the finished elevation from the street and shares it with the office as the sign-off record.
- ·The internal cill is scribed with a coping saw against the reveal plaster, not butted flush with a caulk joint.
- ·The multipoint hooks are lubed with the manufacturer's grease, not household oil that dries and gums.
- ·The old timber cill under a uPVC swap is treated with a boron preservative before the new frame is set over it.
- ·Sealant is a single continuous bead run at the perimeter, not overlapped in six-inch runs.
- ·The old cylinder is disposed of by the crew, not left in a bag on the drive for the client to bin.
- ·The window board is scribed to the plaster line, not left with a caulked gap that shows in raking light.
- ·The friction stay on a new casement is set to the client's preferred restraint at handover — 45°, 90°, or fully open.
- ·Foam gets a wet finger dressed into the internal reveal, not a dry-cut strip that pulls back later.

Faults we fix before recommending garage doors
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.
A door that needs lifting, shoving or a second attempt to lock is warning you before the gearbox fails completely.
