We carry out condensation diagnosis and fixes in Lancaster and across the LA1 area. Condensation forms when warm, humid air meets a cold surface — and a roof lantern is the coldest surface in many kitchens.

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

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 Lancaster and nearby

Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.

We cover Lancaster as part of Lancashire, about 20 miles from Preston.

We also cover nearby Morecambe (3 miles), Fleetwood (12 miles), Thornton-Cleveleys (15 miles).

What should you expect to pay in Lancaster?

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

Most condensation diagnosis and fixes jobs come in between £145 and £495 ex VAT (£174–£594 including 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.
