Blown mineral wool insulation for Tunbridge Wells properties

If your property is in Tunbridge Wells or the TN1 district or nearby Tonbridge, Sevenoaks and Maidstone, it is within our Kent coverage. It is roughly 14 miles south-west of Maidstone.

Tunbridge Wells properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. A suitable wall in Tunbridge Wells is usually filled in a single day from outside, with drill holes made good to match the pointing.

Every elevation is judged on its own exposure. 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.

In terms of approvals, in Tunbridge Wells filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

When is it not the right choice?

Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
