"Upon returning from Christmas vacation we found we had an electrical problem. It eventually caused the breaker to trip and we had no lights in the upper part of our house. It was a couple of days before New Years day and we did not expect to get an electrician until the following week. We were fortunate to find Ron Bonaccorso on Aggie. We called and spoke with Micky, his wife. She checked with Ron and they agreed to come on New Years eve. Micky works as Ron's assistant and together Ron quickly found and fixed the problem. My wife and I want to thank them for taking their time to come on New Years eve. she said"

"William Burden is the third generation owner of WBLightningRods and his company has been in business since 1950. He is very courteous, professional, was on time, and has a very good crew. William was present for the entire installation. We chose the copper system. We are glad for the peace of mind a lightning rod system will provide."
