"Brian installed a dedicated circuit in our basement. Brian answered the first time I called. He set up a time to come and review the job. On the day he came, he called to make sure I was at home. He gave me a reasonable price for the job and agreed to do the work the following week. He came exactly when he said he would and performed the work in the time frame he specified. I am extremely pleased with Brian's work and would highly recommend him to anyone who is in need of electrical work."

"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."

"Dan and his team did a fantastic job. My initial issue ended up being a lot more elaborate than initially anticipated but I was so pleased with their initial work I hired them again to address the larger system issue. I absolutely recommend and will definitely look to hire them again next time I have any electrical problems."
