Condensation forms when warm, humid air meets a cold surface — and a roof lantern is the coldest surface in many kitchens. Send photos from Brentwood (CM14) and we'll tell you which it is — with the price agreed in writing before any work.

Condensation droplets on the inside of roof lantern glass on a cold morning

Signs you need condensation diagnosis and fixes

  • Water on the inside of the glass on cold mornings, even without rain
  • Drips after cooking, showers or drying clothes
  • Wet window sills elsewhere in the house too

Why it happens

Cold surfaces

Older glass, uninsulated kerbs and un-thermally-broken frames stay cold and collect condensation.

Poor ventilation

Without trickle vents, extraction or an opening vent, moist air has nowhere to go.

About Brentwood and the CM14 area

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.

Brentwood is around 11 miles from Chelmsford, and both are within our Essex coverage.

Neighbouring places we cover include Billericay (5 miles), Hornchurch (6 miles), Romford (6 miles).

How much should it cost?

Guide price, per visit£145–£495 ex VAT£174–£594 inc VAT

Most condensation diagnosis and fixes jobs come in between £145 and £495 ex VAT (£174–£594 including VAT), per visit. 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.

Condensation diagnosis and fixes in Brentwood: questions

Do you cover Brentwood?

Yes. We cover Brentwood, including the CM14 postcode area, as part of Essex. Send photos by WhatsApp or the form for a free guide price, and we'll confirm the fixed price in writing before any work starts.

Can you repair a lantern someone else installed in Brentwood?

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.

Will new glass stop condensation?

Better glass raises the inner surface temperature and helps, but if the room is very humid, ventilation matters more. We'll tell you which will make the bigger difference.
