I am researching this subject as a potential customer wants a bid on demoing two old houses. I know about calling in the utility companies to check for gas lines and pulling the service to the houses. But the question I have is in regards to tearing down the actual houses, should I just get an excavator with a thumb attachment or a skid steer with a grapple. I really think the skid steer would not be the way to go as I would have to get too close to the house. Any advice would be appreciated! Thanks.
