We carry out condensation diagnosis and fixes in Newport, Gwent and across the NP10 area. Condensation forms when warm, humid air meets a cold surface — and a roof lantern is the coldest surface in many kitchens.

Condensation droplets on the inside of roof lantern glass on a cold morning

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?

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 Newport, Gwent

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

If you're just outside Newport, Gwent, we also cover Risca (5 miles), Cwmbran (5 miles), Pontypool (8 miles).

How much should it cost?

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 Wales?

In Wales, 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 (as applied in Wales), so we set out the route in writing first. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
