Sounds to me like the home owner did send his own inspector, did the inspector write this down, if so can you email me a copy of the report? I'm a contractor, and this sounds like a scam on his side. You see, sometimes inspectors will point out the violations to the home owner, so that the owner will ask if they know someone who can fix it. Some inspectors may recommend their buddys and make money on the referral. Do not hesitate to challenge the inspectors findings. They are public servants 90% of the time and have to follow more rules. If this was a company owned inspector, then you know he is in for the money on the referral. Also, did he mean replace the box and clean up the wires, or did he mean everything inside the box?
