Condensation forms when warm, humid air meets a cold surface — and a roof lantern is the coldest surface in many kitchens. Send photos from Blyth (NE24) and we'll tell you which it is — with the price agreed in writing before any work.
Signs you need condensation diagnosis and fixes
- Drips after cooking, showers or drying clothes
- Black mould at the base of the lantern lining
- Wet window sills elsewhere in the house too
What usually causes it?
High humidity
Cooking, kettles, showers, drying washing and people all add moisture to the air.
Cold surfaces
Older glass, uninsulated kerbs and un-thermally-broken frames stay cold and collect condensation.
About Blyth and the NE24 area
Colder winters mean more frosty mornings, and a roof lantern is often the coldest surface in a warm kitchen — so condensation is as common as genuine leaks. We check which you've got before quoting.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
We cover Blyth as part of Northumberland, about 8 miles from Morpeth.
If you're just outside Blyth, we also cover Ashington (4 miles), Cramlington (4 miles), Whitley Bay (7 miles).
How much should it cost?
Guide price for condensation diagnosis and fixes: £145–£495 ex VAT (£174–£594 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?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. 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.
