Cavity insulation for new builds and extensions for Ilford properties

If your property is in Ilford or the IG1 district or nearby Barking, Becontree and Leytonstone, it is within our Greater London coverage. It is about 9 miles east of London.

If a wall in Ilford is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. Most Ilford houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.

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.

As for paperwork, in Ilford filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
