Wall tie replacement for Blackheath properties
Our Greater London coverage takes in Blackheath (SE3) and nearby Greenwich, Catford and Eltham. It is about 6 miles south-east of London.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Blackheath properties, so you can choose who fixes them. We never cold-call in Blackheath or anywhere else, and we do not work with doorstep claims companies.
Local weather affects which walls can be filled. 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 Blackheath, 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.
What is included in Blackheath
