We carry out condensation diagnosis and fixes in Milford Haven and across the SA73 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

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

Common causes we find

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 Milford Haven 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.

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.

From Carmarthen to Milford Haven is roughly 33 miles — all part of the Dyfed area we cover.

If you're just outside Milford Haven, we also cover Pembroke Dock (4 miles), Haverfordwest (7 miles), Cardigan (30 miles).

How much should it cost?

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

Typical range: £145–£495 ex VAT, which is £174–£594 with 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?

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 Milford Haven: questions

Do you need to visit to price condensation diagnosis and fixes?

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Which places near Milford Haven do you cover?

As well as Milford Haven, we cover nearby Pembroke Dock, Haverfordwest, Cardigan, Carmarthen 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.
