In Thurso, as everywhere, we're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Several misted or cracked units
- Repeated leaks after previous repairs
- Single-glazed or very poor thermal performance
What usually causes it?
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Rot
Timber lanterns left unmaintained.
Roof lanterns in Thurso
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Close by, we also cover Wick (19 miles), Kirkwall (34 miles).
What should you expect to pay in Thurso?
Most roof lantern replacement jobs come in between £1,995 and £4,995 ex VAT (£2,394–£5,994 including 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 Scotland?
Most lantern repairs in Scotland need no approval at all. Where a job turns into a replacement, the Building (Scotland) Regulations 2004 apply and we confirm how the work will be signed off before we start. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.

Roof lantern replacement in Thurso: questions
How do I get a price for roof lantern replacement in Thurso?
Send a few photos of the lantern and the problem, with your Thurso postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Do you need to visit to price roof lantern replacement?
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.
Can the new lantern use the existing opening?
Usually, if the kerb is sound and the size suits a standard or made-to-measure lantern.
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.
