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

Is it time for condensation diagnosis and fixes?

  • Water on the inside of the glass on cold mornings, even without rain
  • Black mould at the base of the lantern lining
  • Wet window sills elsewhere in the house too

Why it happens

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.

Covering Fulham and nearby

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.

Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.

From Westminster to Fulham is roughly 3 miles — all part of the Greater London area we cover.

Close by, we also cover Chelsea (1 mile), Putney (2 miles), Battersea (2 miles).

What should you expect to pay in Fulham?

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?

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.

Condensation diagnosis and fixes in Fulham: questions

How do I get a price for condensation diagnosis and fixes in Fulham?

Send a few photos of the lantern and the problem, with your Fulham postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

Which places near Fulham do you cover?

As well as Fulham, we cover nearby Chelsea, Putney, Battersea, Shepherds Bush and the rest of Greater London.

Will new glass stop condensation?

Better glass raises the inner surface temperature and helps, but if the room is very humid, ventilation matters more. We'll tell you which will make the bigger difference.

Is condensation in a lantern normal?

Occasional light condensation on very cold mornings can be. Regular dripping isn't, and can damage linings and cause mould.
