We carry out ridge and hip repairs in Greenwich and across the SE10 area. The ridge is where the hip bars and glazing bars meet at the top of a lantern, usually under a moulded or pressed end cap.

Is it time for ridge and hip repairs?

  • Drips near the centre or top of the lantern
  • A cracked or faded ridge end cap
  • Sealant around the ridge cap split or missing

What usually causes it?

UV-damaged end caps

Plastic ridge end caps become brittle and crack, especially on south-facing lanterns.

Poor original sealing

Ridge details are fiddly. If the original sealing was rushed, it's often the first place to leak.

Covering Greenwich 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.

From Westminster to Greenwich is roughly 6 miles — all part of the Greater London area we cover.

Neighbouring places we cover include Blackheath (1 mile), Canary Wharf (2 miles), Catford (2 miles).

Guide prices for ridge and hip repairs in Greenwich

Guide price, per lantern£195–£445 ex VAT£234–£534 inc VAT

Typical range: £195–£445 ex VAT, which is £234–£534 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.

Ridge and hip repairs in Greenwich: questions

How do I get a price for ridge and hip repairs in Greenwich?

Send a few photos of the lantern and the problem, with your Greenwich postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

Can you repair a lantern someone else installed in Greenwich?

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 ridge repair cost?

Usually £195–£445 ex VAT for a standard lantern, confirmed in writing before work starts.

My ridge cap is a different colour from the frame — does that matter?

Faded or chalky caps are a sign of UV damage. Colour alone isn't a leak, but brittle caps crack, so we check them.
