In Alfreton, 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
  • Black mould at the base of the lantern lining
  • Wet window sills elsewhere in the house too

What usually causes it?

Cold surfaces

Older glass, uninsulated kerbs and un-thermally-broken frames stay cold and collect condensation.

Poor ventilation

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

Roof lanterns in Alfreton

Colder winters mean more frosty mornings, and a roof lantern is often the coldest surface in a warm kitchen — so condensation is as common as genuine leaks. We check which you've got before quoting.

Guide prices for condensation diagnosis and fixes in Alfreton

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?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
