During the last service call, i was hoping to get my service done first thing in the morning like the past services. Instead I had to wait for the technician to call right before his arrival which was close to the end ot the timeframe which was at 12 noon. I preferred it if the technician have left a message earlier that my home would be serviced close to midday so I could have used my morning productively.

Thank you, Mary, for your feedback. We understand how frustrating it can be to plan your morning around a service appointment without knowing when the technician will arrive. While our technicians work within scheduled arrival windows, we recognize that better communication about the expected arrival would have helped you plan your day. We appreciate you bringing this to our attention and will share your feedback with our scheduling team as we continue working to improve our customer experience.

Smith Thompson provides both our security alarm monitoring and our pest control. They do both brilliantly! We always get a text before the pest control tech shows up. If we need indoor services, we can let them know. Otherwise, they show up and do their job thorougjly and efficiently. At the first of the year we heard a critter in the attic. We called for service and it was handled so well. Not only did they completely take care of the critter problem, including identifying and closing the entry point, but the tech also brought out attention that he noticed one of the water heaters was leaking into the drip pan. That heads-up allowed us to proactively get our plumber out before it was a big problem.

Great sales experience on the phone with Shawn. He answered all my questions regarding different priced tiers and when technician could arrive! Jeff, Smith Thompson technician, was also really awesome! He has lots of knowledge and expertise with the security system. During each component he was installing, he also explained in detail what he was doing and what it was for! He did not leave until I understood how the unit worked! I am very happy with the outcome and the price is unbeatable! I highly recommend Smith Thompson for your security needs!!
