In Brentwood, 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.

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
What usually causes it?
Open corner joints
The eaves beam is mitred or jointed at the corners; if the joint seal fails, water drops straight through.
Trees and moss
Lanterns near trees fill with leaves every autumn and need regular clearing.
Roof lanterns in Brentwood
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

What should you expect to pay in Brentwood?
Most eaves beam and gutter repairs jobs come in between £175 and £395 ex VAT (£210–£474 including 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.

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.
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.
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.
