In Ystradgynlais, as everywhere, opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos and we'll tell you what we think has failed.
What you might be seeing
- Vent won't open or close
- Leaks from around a closed vent
- Rain sensor doesn't close the vent
Common causes we find
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.
Covering Ystradgynlais and nearby
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.
Close by, we also cover Neath (7 miles), Ammanford (10 miles), Maesteg (12 miles).
What should you expect to pay in Ystradgynlais?
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?
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.
