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.

Roof lanterns in Highlands and Islands

Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

What should you expect to pay for condensation diagnosis and fixes in Highlands and Islands?

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 Scotland?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Scotland. Replacing the whole lantern or enlarging the opening is different and falls under the Building (Scotland) Regulations 2004; we confirm in writing which route applies before any replacement. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.
