Remove and refill in Greenwich

Remove and refill extracts unsuitable or failed cavity insulation, fixes whatever caused the problem, and refills the cavity with a certified system that suits the wall's exposure and condition, so you keep the energy saving without the damp. In Greenwich the visit is priced up front, and any follow-on work is quoted separately so you can choose.

Remove and refill for Greenwich properties

Greenwich sits in Greater London, around 6 miles south-east of London. We work across the SE10 district, including nearby Blackheath, Canary Wharf and Catford.

Where a Greenwich 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. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Greenwich properties, so you can choose who fixes them.

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.

In terms of approvals, if cavity wall insulation follows in Greenwich, 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 refill at all?

Often the original problem was the wrong material for the exposure, poor installation or defects in the outer wall, not cavity insulation as such. Once the defects are fixed and the cavity is clean, a suitable certified system can usually go back in. Where the wall is too exposed for any fill, we say so and leave it empty.
