We carry out eaves beam and gutter repairs in Blackwood and across the NP12 area. The eaves beam is the frame around the base of a lantern, and most designs have a drainage channel inside it that lets water out through small weep slots.

Is it time for eaves beam and gutter repairs?
- Drips along the bottom edge of the lantern
- Moss, leaves or grit visible along the base
- Standing water in the eaves channel
Why it happens
Blocked weep slots
Debris settles at the eaves and blocks the outlets, so the channel fills and overflows inward.
Open corner joints
The eaves beam is mitred or jointed at the corners; if the joint seal fails, water drops straight through.
Covering Blackwood 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.
We cover Blackwood as part of Gwent, about 11 miles from Newport, Gwent.
Close by, we also cover Risca (6 miles), Caerphilly (6 miles), Pontypridd (7 miles).
How much should it cost?
Guide price for eaves beam and gutter repairs: £175–£395 ex VAT (£210–£474 inc VAT), per lantern. 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?
In Wales, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010 (as applied in Wales), so we set out the route in writing first. 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.

Eaves beam and gutter repairs in Blackwood: questions
Do you need to visit to price eaves beam and gutter repairs?
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 Blackwood do you cover?
As well as Blackwood, we cover nearby Risca, Caerphilly, Pontypridd, Pontypool and the rest of Gwent.
Can I clear the eaves myself?
Only if you can do it safely from a properly secured ladder without standing on the roof or leaning on the glass. If in doubt, don't — falls from flat roofs are a common cause of injury.
Why does my lantern only leak at the corners?
Corners are where the eaves beam is jointed and where water collects. A failed corner seal or blocked weep near the corner is the usual cause.
