In Cheltenham, as everywhere, condensation forms when warm, humid air meets a cold surface — and a roof lantern is the coldest surface in many kitchens. Send photos and we'll tell you what we think has failed.

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

Signs you need condensation diagnosis and fixes

  • Water on the inside of the glass on cold mornings, even without rain
  • Drips after cooking, showers or drying clothes
  • 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.

Poor ventilation

Without trickle vents, extraction or an opening vent, moist air has nowhere to go.

Covering Cheltenham 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.

Cheltenham is around 7 miles from Gloucester, and both are within our Gloucestershire coverage.

If you're just outside Cheltenham, we also cover Tewkesbury (7 miles), Gloucester (7 miles), Stroud (12 miles).

What should you expect to pay in Cheltenham?

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

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?

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.

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

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

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.
