Cavity cleaning and debris removal for Chalk Farm properties
If your property is in Chalk Farm or the NW5 district or nearby Camden Town, Holloway and Archway, it is within our Greater London coverage. It is roughly 2 miles north-west of London.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Chalk Farm properties, so you can choose who fixes them. Where a Chalk Farm wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.
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 Chalk Farm, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

Why debris matters
A clean cavity lets water that gets through the outer leaf drain away. Debris piled at the base or caught on ties makes a bridge for that water. It is a common cause of damp low on walls and around ties, with or without insulation.
