Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. We carry out cleaning and maintenance across West Glamorgan, with a guide price from your photos and a fixed price in writing before any work starts.

Signs you need cleaning and maintenance

- Leaves or moss at the eaves
- The lantern is under trees
What usually causes it?

Unnoticed wear

Roof lanterns in West Glamorgan
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.
What should you expect to pay for cleaning and maintenance in West Glamorgan?
Guide price for cleaning and maintenance: £95–£245 ex VAT (£114–£294 inc VAT), per visit. 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 Wales?
Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
