We carry out cleaning and maintenance in Harlow and across the CM17 area. Most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal.

Is it time for cleaning and maintenance?
- Dirty glass or green algae on the frame
- You've never had it checked
- The lantern is under trees
Common causes we find
Algae and dirt
Hold moisture against seals and spoil the view.
Unnoticed wear
Nobody looks at the roof until it leaks.

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.
We cover Harlow as part of Essex, about 16 miles from Chelmsford.
Close by, we also cover Hoddesdon (5 miles), Bishop's Stortford (7 miles), Waltham Abbey (8 miles).
How much should it cost?
Guide price for cleaning and maintenance: £95–£245 ex VAT (£114–£294 inc 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.

Cleaning and maintenance in Harlow: questions
How do I get a price for cleaning and maintenance in Harlow?
Send a few photos of the lantern and the problem, with your Harlow 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.
