Condensation forms when warm, humid air meets a cold surface — and a roof lantern is the coldest surface in many kitchens. Send photos from Aberdare (CF44) and we'll tell you which it is — with the price agreed in writing before any work.

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
  • Drips after cooking, showers or drying clothes
  • 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.

Covering Aberdare and nearby

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.

We cover Aberdare as part of Mid Glamorgan, about 15 miles from Bridgend.

Close by, we also cover Rhondda (4 miles), Merthyr Tydfil (4 miles), Tonypandy (6 miles).

Do you need permission in Wales?

Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. 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 Aberdare: questions

Can you repair a lantern someone else installed in Aberdare?

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.

Which places near Aberdare do you cover?

As well as Aberdare, we cover nearby Rhondda, Merthyr Tydfil, Tonypandy, Pontypridd and the rest of Mid Glamorgan.

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.
