We carry out condensation diagnosis and fixes in Cardigan and across the SA43 area. Condensation forms when warm, humid air meets a cold surface — and a roof lantern is the coldest surface in many kitchens.
What you might be seeing
- Water on the inside of the glass on cold mornings, even without rain
- Drips after cooking, showers or drying clothes
- Black mould at the base of the lantern lining
Why it happens
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.
About Cardigan and the SA43 area
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.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Cardigan is around 22 miles from Carmarthen, and both are within our Dyfed coverage.
Neighbouring places we cover include Carmarthen (22 miles), Haverfordwest (23 miles), Pembroke Dock (30 miles).
Guide prices for condensation diagnosis and fixes in Cardigan
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 Wales?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. 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.

Condensation diagnosis and fixes in Cardigan: questions
How do I get a price for condensation diagnosis and fixes in Cardigan?
Send a few photos of the lantern and the problem, with your Cardigan postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Which places near Cardigan do you cover?
As well as Cardigan, we cover nearby Carmarthen, Haverfordwest, Pembroke Dock, Milford Haven and the rest of Dyfed.
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.
Is condensation in a lantern normal?
Occasional light condensation on very cold mornings can be. Regular dripping isn't, and can damage linings and cause mould.
