In Seaham, as everywhere, most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Leaves or moss at the eaves
- You've never had it checked
- The lantern is under trees
Common causes we find
Debris
Leaves and moss block drainage.
Unnoticed wear
Nobody looks at the roof until it leaks.
Covering Seaham and nearby
Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.
From Durham to Seaham is roughly 10 miles — all part of the County Durham area we cover.

Guide prices for cleaning and maintenance in Seaham
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 England?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.

Cleaning and maintenance in Seaham: questions

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 Seaham?
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.
What does a maintenance visit cost?
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.
