Cavity cleaning and debris removal for Mitcham properties

Mitcham is among the towns we cover in Greater London, alongside Morden, Wimbledon and Streatham. It is about 7 miles south of London.

Damp in an insulated Mitcham home is not always the insulation's fault, so the diagnosis comes before any extraction. If your Mitcham installation has a guarantee, we check it first; the guarantee route may cover the work.

Exposure matters for every cavity wall. 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, if cavity wall insulation follows in Mitcham, 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.
