In March, as everywhere, we're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Several misted or cracked units
- Distorted or sagging frame
- Rotten timber throughout
Why it happens
Structural damage
Impact or movement distorts the frame.
Rot
Timber lanterns left unmaintained.
Covering March and nearby
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
From Cambridge to March is roughly 24 miles — all part of the Cambridgeshire area we cover.
We also cover nearby Wisbech (8 miles), Ely (13 miles), Peterborough (14 miles).
How much should it cost?
Typical range: £1,995–£4,995 ex VAT, which is £2,394–£5,994 with VAT, supplied and fitted. 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.
