We carry out cleaning and maintenance in Penzance and across the TR18 area. Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal.

What you might be seeing
- Dirty glass or green algae on the frame
- Leaves or moss at the eaves
- You've never had it checked
Why it happens
Debris
Leaves and moss block drainage.
Algae and dirt
Hold moisture against seals and spoil the view.
Roof lanterns in Penzance
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.
From Truro to Penzance is roughly 24 miles — all part of the Cornwall area we cover.
Close by, we also cover Camborne (12 miles), Redruth (16 miles), Falmouth (21 miles).
How much should it cost?
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 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.
