We carry out condensation diagnosis and fixes in Chatham and across the ME4 area. Condensation forms when warm, humid air meets a cold surface — and a roof lantern is the coldest surface in many kitchens.

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

Common causes we find

High humidity

Cooking, kettles, showers, drying washing and people all add moisture to the air.

Poor ventilation

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

Roof lanterns in Chatham

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.

Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.

Chatham is around 8 miles from Maidstone, and both are within our Kent coverage.

We also cover nearby Gillingham (1 mile), Rochester (1 mile), Strood (2 miles).

What should you expect to pay in Chatham?

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?

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.
