In Blackburn, as everywhere, 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. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Drips along the bottom edge of the lantern
- Water at the corners after heavy rain
- Staining on the lining just below the eaves
Common causes we find
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.
About Blackburn and the BB1 area
Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

Guide prices for eaves beam and gutter repairs in Blackburn
Typical range: £175–£395 ex VAT, which is £210–£474 with 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 England?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.

Eaves beam and gutter repairs in Blackburn: 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.
Can you repair a lantern someone else installed in Blackburn?
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.
How much does an eaves repair cost?
Clearing and resealing is usually £175–£395 ex VAT; rebuilding a damaged eaves section is priced on survey. You get a fixed price in writing first.
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.
