We carry out cleaning and maintenance in Chalk Farm and across the NW3 area. Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal.

Signs you need cleaning and maintenance
- Dirty glass or green algae on the frame
- Leaves or moss at the eaves
- You've never had it checked
What usually causes it?
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.
Covering Chalk Farm 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.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
We cover Chalk Farm as part of Greater London, about 3 miles from Westminster.
We also cover nearby Camden Town (1 mile), Holloway (1 mile), Archway (2 miles).
How much should it cost?
Most cleaning and maintenance jobs come in between £95 and £245 ex VAT (£114–£294 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.

Cleaning and maintenance in Chalk Farm: questions
How do I get a price for cleaning and maintenance in Chalk Farm?
Send a few photos of the lantern and the problem, with your Chalk Farm postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Do you need to visit to price cleaning and maintenance?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Do you clean the inside of the glass?
We can, where safe access from inside is possible; let us know when booking.
Can you set up regular visits?
Yes — tell us how often you'd like us to come and we'll confirm the price per visit in writing.
