In Reigate, 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
  • 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 Reigate and nearby

Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.

Reigate is around 16 miles from Guildford, and both are within our Surrey coverage.

We also cover nearby Redhill (2 miles), Horley (5 miles), Banstead (6 miles).

How much should it cost?

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.

Condensation diagnosis and fixes in Reigate: questions

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

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

Can you repair a lantern someone else installed in Reigate?

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.
