Remove and refill for Welling properties
Welling sits in Greater London, roughly 11 miles east of London. We work across the DA16 district, including nearby Bexley, Eltham and Thamesmead.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Welling properties, so you can choose who fixes them. If your Welling installation has a guarantee, we check it first; the guarantee route may cover the work.
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 Welling, 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.
