We have had Smith Thompson for the last seven years and couldn’t be happier. Luis came out to service our property and went above and beyond for us. He was competent, knowledgeable, thorough, thoughtful, and efficient. Most companies these days try a bait and switch or attempt to convince a homeowner hundreds of dollars in add ons are required. Smith Thompson is always a breath of fresh air. Top tier service at a fair price with no gimmicks. Thank you!

Phone support is reliable and answers quickly. We also recently had a technician come in person, and it was the same technician who had installed our system years ago, so he had his notes and was able to quickly resolve the issue.
Love the local service and the familial touch of this business, and I recommend them to anyone seeking an alarm company.

We had a local alarm and security system in Houston for over 20 years that just suddenly up and left the business, leaving us high and dry.
So, I started my search for an alarm company that could reuse what we already had in place. I found Smith Thompson Home Security Systems advertising “Use your existing system”, so I gave them a call.
Their salesman, Shawn, explained what they could and couldn’t reuse from our existing system and covered the cost of what changes would need to be made. I felt the cost was very reasonable and liked the fact that no contract was required. An appointment was scheduled for a technician to come out.

John, the technician, came out on time and was very knowledgeable of our alarm system and knew what needed to be done. While upgrading the system, he found that part of the existing system was not working and explained what options we could take to resolve the issue.
They have very fair pricing and work with you as an individual homeowner. We were very impressed with the process and overall professionalism and would recommend this company without hesitation to family and friends.

I have been with SmithThompson for almost Five years and they are the world class Home Security company hands down. I have enjoyed the best service that I have recommended and referred to my daughter and neighbors and they have switched to SmithThompson in the last Two years. Their top notch management like Mr.Thompson and Elias, Great knowledgeable technician Tony and Luis, and friendly call center representatives are the BEST in industry. I would highly recommend SmithThompson Home Security to anyone without any hesitation regardless of needs for the Alarm or Pest Control.
