Chris was really thorough looking everywhere under units for me to find Rat entry point. Found hole and used wirewall to deter it, as can't get behind units now, also may have found outside entry point under old fascia board, which he is coming back to do for me next week. This is such a challenge a rat coming into your home that you can't see as is under floorboards or in the cavity wall can drive you mad, chris was really calm and took this all in his stride, I'm sure we will get there in the end to deter rats entry. I would get him back for different work in the future too, as I could tell he knows alot about building works, he explained a few other problems I am having with my old house. Very polite and friendly. a nice guy to have working in your home.
