Today the tech was at our home to install upgraded equipment to our security alarm. He was here early within the window of time that was scheduled. He was very professional and completed the job within 15 minutes. Very pleased with Smith Thompson home security.
We have been with Smith Thompson for 3 years now and we find them to be honest and excellent at what they do. We have been so pleased with our security service. I would highly recommend them for your home security and alarm monitoring service.
We appreciate your long term business!
Great service an even better price. NOBODY in the DFW Metroplex can compete.
Thank you much! There are several really good companies in the DFW area, but since we are fiercely independent and do everything in house, we really try harder. Very important things, like our 24 hour monitoring, are not sub contracted out, which is very common in our industry.
Very excellent service easy to set up and use and very helpful.
Appreciate the kind words...and your business!
Thanks Pete!
Smiththompson security is the best home security we ever had. Customer servicer is top notch, the installation guy was really nice and professional. Would highly recommend. A+++
Thanks so much!
Troy Burleigh from Smith Thompson Pest Control just finished his pest control and I highly recommend him as well as all the services provided by the entire Smith Thompson Family.
We're fortunate to have Troy, he's great! And thank you for your business!
Appreciate that!
We had some doors replaced and the result was an inability to set the alarm system. Our system is part old wiring and part wireless. We contacted ST support and got Aaron. He went through the protocols, gave me understandable directions, evaluated the system and came up with the problem. He immediately scheduled a tech and helped me to get the majority of the system back on line. Couldn't have been easier and more thorough. Thanks guys and gals.
Thanks for the kind words!
We have been so pleased with our security service with Smith Thompson. As new homeowners, it was important to us to feel like we had quality security at an affordable cost, and Smith Thompson has proven to be all of that and more. The customer service is excellent, and we absolutely love getting to support a local business. We would recommend Smith Thompson to anyone and everyone!
Thank you, and appreciate the recommendation!
Appreciate your business!
Thank you!
Awesome company, love their incentives of getting a free month for paying upfront and they have always had quick responses if/when the alarm goes off.
That's right! We offer an optional annual payment plan where if you pay 11 months, we give you the 12th free! And if you cancel anytime, we simply refund the unused portion, so nothing to lose. Thanks for your business!
Our technician from Smith Thompson Home Security in Houston was very professional and walked me through the operations of the new security system, including the mobile app. I would recommend them for their low rate and professional services.
Thanks James, appreciate your business!

We appreciate your business!
Smith Thompson was very prompt. The work was completed and we were extremely satisfied. Customer service was excellent. Love the pest control service also. We used someone else with many problems. It only took Smith Thompson once to correct our problem.
Thank you so much for trying our pest control too!
Great Company! Has always been very efficient in contacting us. Love that we can pay our bill on-line now. Thank You for your Service.
Thanks Patricia! Yes, the pay on line portal is getting better as well.
Reliable, prompt, and responsive. Been a customer over 5 years, never any issues
We really appreciate our long time customers! Thank you much!
I have been very pleased with Smith Thompson. I never leave home worried about someone breaking in to my home. Because I know this company will contact me immediately. We set off the alarm sometimes by mistake and they are calling one of our phone numbers to make sure that everything is ok asap. Their rates are cheap and I just love them.
Yes, our rates have been the same for over 42 years now. Thank you so much for your trust!
We have really enjoyed our experience with Smith Thompson so far. The initial installation was very quick, and the service person that came to our house was very nice, punctual, and patient. He explained everything we needed to know about the alarm. The couple times that we accidentally triggered the alarms, Smith Thompson called within a minute to ask for our passcode etc.! Always so on top of things, and we have been more than satisfied!
Thanks so much, and we appreciate your business!
