The Wiltshire market is defined by stone villages, market-town terraces and military-town semis with consistent extension activity — and our Trowbridge installs reflect that, with specifications matched to the property rather than pulled off a shelf.
Specification doesn't change with postcode: thermally broken frames, 28mm argon-filled glazing, marine-grade powder coating and a 10-year guarantee, whether you buy supply-only for your own builder or book our installation teams.
Our teams cover Trowbridge alongside Marlborough, Calne and Westbury and the rest of Wiltshire — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.

The lantern doesn't, but the junction detail differs: EPDM wraps the kerb, GRP laminates onto it, felt is torch-dressed. We supply the right drawing for each.
Almost always the junction, not the lantern — short upstands, membrane finished under rather than over the kerb, or missing seals. Build the kerb right and dress the membrane right, and the assembly is dependable for decades.
A timber kerb at least 150mm above the finished roof surface, built to the lantern's external footprint. We issue exact dimensions at order so it's ready before the lantern arrives.
On installed projects, we coordinate it: the roofer dresses the membrane over the kerb, we bed and seal the lantern onto it. Supply-only orders include junction drawings for EPDM, GRP and felt so your roofer details it correctly.
Yes — Trowbridge is inside our standard Wiltshire coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Trowbridge on dedicated glass transport.
Stocked standard sizes typically deliver to Trowbridge within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
