Damp proofing in London

Phone numbers for damp proofing firms in London — rising damp, penetrating damp and timber treatment. London boroughs only, not Slough or Reading. Open a profile and phone the business yourself. This site does not send the job.

Ask whether the visit is a survey, a treatment, or both. Not every wet wall needs a new damp course. This London list is the City of London and the 32 London boroughs, including Croydon, Bromley, Ealing and Harrow. Slough, Watford, Reading and Luton are not added to it. Profiles show a name, the area they cover and a phone number. Public qualifications such as Gas Safe or NICEIC appear only when they are on the profile. Read the cost notes before you treat a number as the price. A figure on a card is not a quote from this site.

How to read a price for rising damp, penetrating damp and timber treatment

The Checkatrade damp proofing cost guide, table last updated June 2026, puts a chemical injection at £60–£200 a metre, average £100, including VAT. It also cites about £5,000 for a typical property. That property figure is not a short injection. The guide says plaster, decoration, drying and the survey sit outside those prices. It does not publish a total for this city. Victorian and Edwardian terraces, mansion blocks and converted flats are common, so access, parking and how waste leaves the street often sit beside the labour. In a London terrace, the party wall and the plaster that has to come off often cost more than a short injection. A figure here is not a quote from this site. Checked 14 October 2026.
