Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The county's housing stock — slate-built terraces and Snowdonia farmhouses — exposure ratings and slate-grey frames are popular — shapes our recommendations here more than any brochure could.
You get the same product either way — thermally broken aluminium, self-clean and solar-control glass options, made to the millimetre. The only choice is who fits it: your builder with our documentation, or our own nationwide teams.
Very. Domes sit on the same style of kerb a lantern needs, so a swap to a modern glazed lantern is typically a one-day changeover that also transforms how the room looks and holds heat.
Minimal — the work happens at roof level. Inside, expect the reveal to need a trim or touch of decoration; the room is usable again the same evening.
If it's single-glazed, non-thermally-broken or streaming with condensation, the comfort and energy gains are substantial. We'll be honest on survey if yours has life left in it.
We remove and dispose of it as part of the installation — the price we quote includes taking the old unit away.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
