In Folkestone, 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

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

Common causes we find

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.

Roof lanterns in Folkestone

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.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

Guide prices for condensation diagnosis and fixes in Folkestone

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 Folkestone: questions

Do you need to visit to price condensation diagnosis and fixes?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Can you repair a lantern someone else installed in Folkestone?

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

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.

What does a condensation visit cost?

Diagnosis visits start from £145 ex VAT. Any fixes are priced separately and confirmed in writing before work starts.
