I haven't had service performed in years and I knew my irrigation system wasn't working properly but didn't do anything about it until I saw a huge puddle of water in my yard caused by leaking valves. Lawn Sprinker Tech came out the same day! My system is 12 years old and needed some overhauling in order to save money on wasted water. I am so grateful for their honesty in trying their best to save me money. I was totally unaware that I could have annual maintenace performed to prevent these things from happening. From now on, I will use them for maintenance as well. I am very pleased with their knowledge & professionalism.
