Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Dorchester and the wider county, housing stock runs to coastal villas, thatched villages and retirement bungalows — light-filled garden rooms are a major driver. We've specified and supplied for exactly these property types across Dorset, so recommendations come from real local precedent.
Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.
Dorchester, Wimborne Minster, Sherborne and Blandford Forum and the rest of Dorset all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.
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.
Yes — installation is available across Dorchester and Dorset, and if you'd rather buy supply-only, kerbside delivery to Dorchester is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Dorchester usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
