Damp investigation after cavity insulation for Islington properties
Our Greater London coverage takes in Islington (N1) and nearby Highbury, Holloway and Camden Town. It is roughly 2 miles north-east of London.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Islington properties, so you can choose who fixes them. Damp in an insulated Islington home is not always the insulation's fault, so the diagnosis comes before any extraction.
Local weather affects which walls can be filled. Much of Greater London sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
In terms of approvals, if cavity wall insulation follows in Islington, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
