Damp investigation after cavity insulation in Tottenham

For properties in Tottenham, a damp investigation starts with a clear price and ends with a written record of what was found and done. A damp investigation finds out why an insulated wall is showing damp or mould: rain getting in through defects, bridged or wet fill, debris in the cavity, a breached damp-proof course, or condensation.

Damp investigation after cavity insulation for Tottenham properties

Tottenham is among the towns we cover in Greater London, alongside Edmonton, Wood Green and Walthamstow. It is around 7 miles north of London.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Tottenham properties, so you can choose who fixes them. If your Tottenham installation has a guarantee, we check it first; the guarantee route may cover the work.

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 Tottenham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
