Blown mineral wool insulation for Wimbledon properties
If your property is in Wimbledon or the SW19 district or nearby Morden, Mitcham and Putney, it is within our Greater London coverage. It is roughly 7 miles south-west of London.
Most Wimbledon houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. If a wall in Wimbledon is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.
Wind-driven rain is the first thing the surveyor weighs up. 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.
On the rules side, in Wimbledon filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Why choose mineral wool?
Mineral wool fibres are treated to shed water, so moisture that gets into the outer leaf runs down the cavity rather than tracking across. It is classed as non-combustible, which matters for some flats and taller buildings, and it is usually the lower-cost certified option.
