In Witham, as everywhere, if the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos and we'll tell you what we think has failed.

What you might be seeing
- The room is noticeably hotter than the rest of the house in summer
- Furniture or flooring fading under the lantern
- Clear, uncoated glass in an older lantern
Common causes we find
Clear or standard Low-E glass
Standard units let a lot of solar heat through; solar control coatings reflect more of it.
Orientation
South- and west-facing lanterns gain the most heat in the afternoon.
Covering Witham and nearby
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.
From Chelmsford to Witham is roughly 9 miles — all part of the Essex area we cover.
Neighbouring places we cover include Maldon (5 miles), Braintree (7 miles), Chelmsford (9 miles).
How much should it cost?
Guide price for solar control and self-cleaning glass upgrades: £345–£895 ex VAT (£414–£1,074 inc VAT), per glass unit. 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.

Solar control and self-cleaning glass upgrades in Witham: questions
Can you repair a lantern someone else installed in Witham?
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 Witham do you cover?
As well as Witham, we cover nearby Maldon, Braintree, Chelmsford, Colchester and the rest of Essex.
Can you add a film instead?
Films are cheaper but can affect the unit's warranty and may not suit sloped double glazing. We'd rather replace the unit properly.
Does self-cleaning glass mean no cleaning?
It reduces cleaning on the outer face but still needs rain and occasional rinsing, and the inside still needs cleaning.
