Cavity wall insulation removal in Tonbridge

Cavity wall insulation removal in Tonbridge is priced before you book, and what we find is written up with photos.

Cavity wall insulation removal for Tonbridge properties

Tonbridge sits in Kent, about 12 miles south-west of Maidstone. We work across the TN9 district, including nearby Tunbridge Wells, Sevenoaks and Maidstone.

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

Wind-driven rain is the first thing the surveyor weighs up. Much of Kent 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.

On compliance, if cavity wall insulation follows in Tonbridge, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

How extraction works

Bricks are carefully removed in a line near the base and at intervals higher up where needed. The fill is broken up and drawn out with an extraction vacuum, the cavity is cleared and checked with a camera, and the bricks are rebuilt in matching mortar. Extracted material is bagged and disposed of properly.
