Blown mineral wool insulation in Reading

Blown mineral wool insulation for Reading properties

If your property is in Reading or the RG1 district or nearby Lower Earley, Wokingham and Crowthorne, it is within our Berkshire coverage. Reading is one of the main towns we cover in Berkshire.

If a wall in Reading 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. Reading properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.

Wind-driven rain is the first thing the surveyor weighs up. Much of Berkshire 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 Reading filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

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.

What is included in Reading
