Hi there. I had a gap on my new build extension. The gap is where the plastic upvc cladding is and there is like a 10cm gap between the brick wall upto the plastic part. Should I fill the whole gap from start to finish with expanding foam? Mice are going in and out because its open and I want to stop this. Thats the entry they are getting because I can hear them dropping in my living room ceiling
