Wall tie replacement for Welling properties

Welling sits in Greater London, about 11 miles east of London. We work across the DA16 district, including nearby Bexley, Eltham and Thamesmead.

Damp in an insulated Welling home is not always the insulation's fault, so the diagnosis comes before any extraction. 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.

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.

In terms of approvals, 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.

Ties and cavity insulation

Ties should be checked before a cavity is filled. Fitting remedial ties does not normally stop a cavity being insulated later, and we can do both in one visit. Where cracking suggests movement, we recommend a structural engineer's view first.
