Existing insulation and guarantee check for Becontree properties

Becontree is among the towns we cover in Greater London, alongside Dagenham, Barking and Ilford. It is around 11 miles east of London.

Every inspection point in Becontree is photographed and logged, so you have a record to show a buyer, lender or contractor. A survey in Becontree gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Every elevation is judged on its own exposure. 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 Becontree, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How to tell if a house already has cavity insulation

Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
