In Castle Douglas, 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
- Distorted or sagging frame
- Repeated leaks after previous repairs
Why it happens
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Structural damage
Impact or movement distorts the frame.
Roof lanterns in Castle Douglas
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.
Castle Douglas is around 15 miles from Dumfries, and both are within our Dumfries and Galloway coverage.

What should you expect to pay in Castle Douglas?
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.
