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. Send photos from Wembley (HA0) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- 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.
Movement at the junction
Several bars meet at one point and each moves slightly with temperature; the seals at the ridge take the strain.
About Wembley and the HA0 area
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
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 Wembley is roughly 8 miles — all part of the Greater London area we cover.
Close by, we also cover Harrow (2 miles), Greenford (3 miles), Willesden (3 miles).
How much should it cost?
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?
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.

Ridge and hip repairs in Wembley: questions
Can you repair a lantern someone else installed in Wembley?
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.
Which places near Wembley do you cover?
As well as Wembley, we cover nearby Harrow, Greenford, Willesden, Northolt and the rest of Greater London.
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.
Can you replace just the ridge cap?
Yes, if a compatible cap is available and the seals underneath are sound.
