Cavity wall insulation for Wokingham properties
Wokingham is among the towns we cover in Berkshire, alongside Crowthorne, Bracknell and Lower Earley. It is around 7 miles south-east of Reading.
If a wall in Wokingham 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. Wokingham properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Local weather affects which walls can be filled. 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.
For regulations, in Wokingham filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Is my wall suitable for cavity wall insulation?
Most homes built from the 1920s onwards have cavity walls, but having a cavity is not the same as being suitable. The Energy Saving Trust's rule of thumb is a cavity of at least 50mm, clear of rubble, behind masonry in good condition, on a wall that is not exposed to severe driving rain or flood risk.
