Covering Cwmbran 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 Cwmbran as part of Gwent, about 5 miles from Newport, Gwent.

Neighbouring places we cover include Pontypool (3 miles), Risca (5 miles), Newport, Gwent (5 miles).

How much should it cost?

Guide price, per visit£95–£245 ex VAT£114–£294 inc VAT

Most cleaning and maintenance jobs come in between £95 and £245 ex VAT (£114–£294 including 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.

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.

Usually £95–£245 ex VAT per visit depending on size and access, confirmed in writing before the visit.

Do you clean the inside of the glass?

We can, where safe access from inside is possible; let us know when booking.
