Cavity wall insulation removal in Gravesend

For properties in Gravesend, cavity wall insulation removal starts with a clear price and ends with a written record of what was found and done. Cavity wall insulation removal takes failed fill out of the cavity, usually by lifting bricks at low level and extracting the material with an industrial vacuum and rods, then cleaning the cavity and rebuilding the brickwork.

Before any material is chosen, exposure is checked. 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.

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.
