Existing insulation and guarantee check for Stratford properties

Stratford is among the towns we cover in Greater London, alongside Bow, Canning Town and Canary Wharf. It is around 6 miles east of London.

Every inspection point in Stratford is photographed and logged, so you have a record to show a buyer, lender or contractor. Where a Stratford wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.

Wind-driven rain is the first thing the surveyor weighs up. 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 Stratford, 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.
