"I hired Kloock's Electric to install a television antenna. They came out to do an estimate and we discussed equipment options. I decided on an antenna and amplifier and requested that they install the antenna strapped to a chimney. I received a quote for the work and equipment costs. They ordered the equipment and came out to install it when the equipment arrived. The install went well, and it was apparent that the installer had done this before. They were professional and courteous."
