How Do I Know If My Cavity Wall Has Already Been Filled Or Not?

Jonathon Gregory

Usually you can tell if your cavity wall has already been filled or not. Most of the time if you look at the brickwork of your property you may be able to see small drill holes in the corner of your bricks under the window.

Alternatively, we tend to drill holes in a diamond shape, which should be visible if you look closely at the brickwork on your property. If this is the case, then the chances are you cavity has already been filled. If not, then you can always give us a call and we can talk you through the next steps to having insulation installed.
