I do not recommend this service. When I contacted Robert Terwilliger, he agreed to come to my house to service and repair an antique grandfather clock. He told me that he would need $250 cash for this service. Mr. Terwilliger came with a co-worker, who he directed to do the various tasks. Mr. Terwilliger's co-worker worked for about an hour, and then they told me that the clock was working fine. Within 15 minutes of their departure, the clock stopped working. I called the next day, and he told me to restart it, over the next few days every time it stopped, by pushing the pendulum. I did that, to no avail, and called Mr. Terwilliger a few days later. He informed me that I needed to disassemble the clock and take it to him, whereupon he would clean it for $350, and then I would need to take it back to my house and assemble it myself. When I asked him about the $250 that I already paid him, he told me that that money was gone, and that he would not stand by his work. When I told him that, if I followed his request for the additional money and transporting and assembling the clock myself, he could always say that the clock wasn't working because of my mistakes, not his, he told me that was a possibility. What kind of business does not stand by its work, and then asks for more money with no guarantee that my prized family possession will work at the conclusion of the service?
