"Brian is easy to get a hold of and easy to work with. He came out on a Saturday to take a look at a leak around my sliding glass door. Worked hard for 4 straight hours installing a fix. Would recommend."

"Our experience with Ultra Guard Security Systems was great! Our system was specifically designed to fit our needs. Lindsey Pearce came up with what was needed and right for us. They were able to update the existing system and integrate it with their new parts and technology. The installation went flawlessly. The team of employees doing the installation were knowledgeable and competent in their field. We would highly recommend Ultra Guard Security Systems for and work you need done whether you need an upgrade or a whole new system."

"Todd, the owner took my call and gave me a quote to install recessed lights and track lights and switchs. He was very thorough, professional courteous. He gave me a very reasonable quote on my first call and set up a convenient time for installation..He gave me a reminder call the day before and a few minutes before arriving his staff arrived. The electricians were very professional and put down protective measures to keep the area clean, They minimized the area that had to be cut in the wall to do the wiring for the 3 new Recessed Lights and Switches. They covered the work area with plastic and cleaned up after the job. I highly recommend this C.T. Smith Electrical Services, LLC for timely, quality, electrical work. I am a happy satisfied customer and give them a five-star rating and recommendation."
