We had a great experience with Smith Thompson
recently for our home in downtown Houston! I was referred to Smith Thompson by a friend after expressing frustration with some of the larger brands that lock you into a 3 year contract. We called to inquire about the most cost-effective...

100% Satisfied
From the first phone call to the actual use of our security system we have been 100% satisfied! The technician was knowledgable and courteous. He was able to answer all my questions and get the system up and running in no time. Thank you Smith Thompson Home Security for making our home more secure and at an affordable price to do so!!!!

A breeze so far!
Everything about Smith Thompson has been a breeze so far! The tech that installed our system was extremely knowledgeable- we had a lot of questions. He was not pushy with products, just presented our options.. which I appreciated a lot. I have enjoyed the service & would definitely recommend. You can’t be the prices either!

Simple, easy, and straight forward.
We just moved into our new home... and dealt with many different companies and their representatives. So far, our experience with Smith Thomson is the best. They made it simple, easy, and straight forward -- just the way we expected. And best of all their price is very reasonable and affordable. Highly recommended. Wish to see more businesses like Smith Thompson...
