About Welwyn Garden City and the AL8 area
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.
Welwyn Garden City is around 6 miles from St Albans, and both are within our Hertfordshire coverage.
Neighbouring places we cover include Hatfield (3 miles), Hertford (6 miles), St Albans (6 miles).
How much should it cost?
Guide price for commercial roof lantern repairs: £495–£2,995 ex VAT (£594–£3,594 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?
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.
