We carry out cleaning and maintenance in Johnstone and across the PA5 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
- The lantern is under trees
What usually causes it?
Debris
Leaves and moss block drainage.
Algae and dirt
Hold moisture against seals and spoil the view.
Covering Johnstone and nearby
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.
In built-up areas, access is often the hardest part of the job — through the house, over a neighbour's roof, or with parking restrictions. We plan access in advance and price any tower or scaffold into the quote.
From Glasgow to Johnstone is roughly 10 miles — all part of the Glasgow and Clyde area we cover.
Close by, we also cover Paisley (3 miles), Renfrew (6 miles), Clydebank (7 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 Scotland?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. 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.
