01 · Aluminium glazing
Our speciality. Slim frames, wide openings, and the survey work that makes them run true for years.

Two to seven panels, thermally broken, set on a track that is dead level. Our speciality, from survey to final adjustment.
Bigger panes, slimmer frames and nothing folding into the room. The door to choose when the view matters most.

Narrow, thermally broken frames in any colour, with big fixed panes where you want them.

Steel-look aluminium doors, glazed screens and partitions that pass daylight through the house.
02 · Windows
uPVC and aluminium, casement and flush sash, bays and bows — measured opening by opening.

Casement and flush sash windows from REHAU, VEKA and The Residence Collection, made to measure and fitted properly.

Replacement bays for terraces, thirties semis and modern houses — surveyed for the structure above as well as the frames.
03 · Doors
Front, back and French doors in composite, aluminium and uPVC, hung square and set to lock cleanly.

Solid-core composite doors from Endurance Doors and Cannondoor, hung square with a lock that throws without a shove.

Flat, modern door slabs with slim frames and long bar handles — for homes and commercial units.

Back doors, French doors and porch doors — the practical, good-value option, fitted with the same care.
04 · Roofs, roofline & repairs
Warm roofs, fascias, soffits, guttering and cladding — and honest repairs to what is already there.
Replace a cold polycarbonate or glass conservatory roof with an insulated, tiled WarmerRoof system.
Old timber boards stripped out, not capped over — new uPVC fascias, soffits and guttering fitted to last.
Weatherboard and shiplap cladding for gables, dormers, bays and extensions — the look of timber without the painting.
Misted units, dropped doors, stiff handles and failed locks. If a repair will genuinely do the job, that is what we recommend.

Frames are made to your sizes, then fitted on an agreed date. Dust sheets down, one opening at a time, and the house watertight and secure before we leave each evening.
