We carry out upstand and kerb repairs in Bushey and across the WD23 area. The upstand, or kerb, is the raised frame the lantern sits on.

Signs you need upstand and kerb repairs

  • Water appearing below the lantern rather than from the glass
  • Soft or spongy timber at the base of the lantern
  • Ponding water against the kerb after rain

Why it happens

Kerb too low

If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.

Membrane not dressed up

The flat roof covering should run up the kerb and be trimmed or flashed. If it stops short, water gets behind it.

Roof lanterns in Bushey

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

Bushey is around 7 miles from St Albans, and both are within our Hertfordshire coverage.

What should you expect to pay in Bushey?

Guide price, per lantern£395–£1,295 ex VAT£474–£1,554 inc VAT

Guide price for upstand and kerb repairs: £395–£1,295 ex VAT (£474–£1,554 inc 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.
