Condensation forms when warm, humid air meets a cold surface — and a roof lantern is the coldest surface in many kitchens. Send photos from Farnham (GU9) and we'll tell you which it is — with the price agreed in writing before any work.

Condensation droplets on the inside of roof lantern glass on a cold morning

What you might be seeing

  • Water on the inside of the glass on cold mornings, even without rain
  • Drips after cooking, showers or drying clothes
  • Black mould at the base of the lantern lining

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.

Roof lanterns in Farnham

Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

Farnham is around 10 miles from Guildford, and both are within our Surrey coverage.

We also cover nearby Aldershot (3 miles), Fleet (5 miles), Farnborough (6 miles).

What should you expect to pay in Farnham?

Guide price, per visit£145–£495 ex VAT£174–£594 inc VAT

Typical range: £145–£495 ex VAT, which is £174–£594 with 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.
