Wall tie replacement for New Malden properties

New Malden is among the towns we cover in Greater London, alongside Surbiton, Morden and Wimbledon. It is about 9 miles south-west of London.

If your New Malden installation has a guarantee, we check it first; the guarantee route may cover the work. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for New Malden properties, so you can choose who fixes them.

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.

For regulations, if cavity wall insulation follows in New Malden, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
