We carry out opening vent and actuator repairs in Carmarthen and across the SA31 area. Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor.

Open electric vent in a roof lantern with chain actuator visible from inside

What you might be seeing

  • Leaks from around a closed vent
  • Rain sensor doesn't close the vent
  • Remote or switch unresponsive

Why it happens

Actuator failure

Chain actuators wear out or jam, especially if they've been forced.

Seal or hinge problems

A twisted hinge or worn seal stops the vent closing tight.

Roof lanterns in Carmarthen

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.

Neighbouring places we cover include Llanelli (13 miles), Ammanford (14 miles), Gorseinon (17 miles).

What should you expect to pay in Carmarthen?

Guide price, per vent£195–£545 ex VAT£234–£654 inc VAT

Guide price for opening vent and actuator repairs: £195–£545 ex VAT (£234–£654 inc VAT), per vent. 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.
