We carry out eaves beam and gutter repairs in Mitcham and across the CR4 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.

What you might be seeing
- Drips along the bottom edge of the lantern
- Water at the corners after heavy rain
- Standing water in the eaves channel
What usually causes it?
Blocked weep slots
Debris settles at the eaves and blocks the outlets, so the channel fills and overflows inward.
Trees and moss
Lanterns near trees fill with leaves every autumn and need regular clearing.
Covering Mitcham and nearby
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.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
Mitcham is around 7 miles from Westminster, and both are within our Greater London coverage.
Neighbouring places we cover include Morden (1 mile), Wimbledon (2 miles), Streatham (2 miles).
What should you expect to pay in Mitcham?
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?
In England, 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, so we set out the route in writing first. 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.

How much does an eaves repair cost?

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.
