We carry out uPVC roof lantern repairs in Chiswick and across the W4 area. Many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings.
What you might be seeing
- Yellowed or brittle end caps
- Cracked cappings or ridge covers
- Green algae along the bars
What usually causes it?
UV ageing
uPVC components become brittle and crack after years of sun.
Blocked drainage
As with all lanterns, blocked eaves drainage causes overflow.
Roof lanterns in Chiswick
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.
Chiswick is around 5 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Chiswick, we also cover Acton (1 mile), Barnes (1 mile), Shepherds Bush (2 miles).
What should you expect to pay in Chiswick?
Typical range: £175–£595 ex VAT, which is £210–£714 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.
