About Harwich and the CO12 area
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
From Chelmsford to Harwich is roughly 38 miles — all part of the Essex area we cover.
We also cover nearby Felixstowe (3 miles), Ipswich (10 miles), Clacton-on-Sea (12 miles).
What should you expect to pay in Harwich?
Typical range: £1,995–£4,995 ex VAT, which is £2,394–£5,994 with VAT, supplied and fitted. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.

Roof lantern replacement in Harwich: questions

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

Standard sizes typically £1,995–£4,995 ex VAT supplied and fitted; bespoke sizes and kerb rebuilds are priced on survey. You get the fixed price in writing first.
Will you tell me if repair is enough?
Yes. We'd rather do a repair that works than sell a lantern you don't need.
