Jaiden was amazing! He was really nice and informative. This is my second irrigation company I’ve worked with and by far the best! I will be requesting him next time I have work done.

Can't say enough good things about them. Took me forever to find a contractor that actually wanted my business. They installed my system later summer, early fall. Their communication is top notch, and their follow through on service is great. Count me as a happy customer.

I was so impressed with Jayson our technician today. You can really tell he takes pride in his job and he is so courteous and nice! He took the time to explain what he was doing and answered any questions I had. At each step of the process (we had a couple of repairs) he made sure I was informed and given choices on what I wanted to do. He went the extra mile which is hard to find today. He made me a life long customer.

I recently used Professional Irrigation Systems to install a system at my house in O'Fallon, MO. I live on a quarter acre lot (pretty standard for homes in the area). I went with their platinum package and the wifi controller. I highly recommend the wifi controller. For the cost, its worth the functionality and control. I also got an add on to extend a couple of down spouts away from my house.I got a few quotes and while some were slightly cheaper and others a bit more, I liked the reputation and service other reviewers recommended. Several people in my neighborhood have a system done by them and their lawns look good, so that's how I end up choosing them.Pros:1. Single day, professional installation2. Programming set up (if you use wifi controller) with training3. Fixed any errors quickly (I wanted the back 2 down spouts extended, they did the front 2. When I brought it to their attention, they came back and installed the 2 I had requested initially and didn't charge me for the 2 that were mistakenly done)4. Set up sprinkler adjustments to water where I wanted to water5. Responsive Sales Team6. 0% interest offer (through Wells Fargo based on credit score)7. $500 off Hunter Irrigation when I purchasedCons:1. Cost can be a bit higher, but in my experience, you pay for quality.2. Installed down spouts on wrong corners (but they fixed it at their cost and now I have 4 corners covered instead of 2)3. Project was utility flagged 2 to 3 weeks ahead of the work. This was a pain to mow around (especially in a riding mower).4. Did not communicate when team was going to come out to extend the correct downspouts (didn't realize it until I heard them working outside)So overall, how they corrected the error, the financing/discount available, and the general level of quality work and functional utility, I can't dock a full star. I'd say 4.5 if that was an option (mainly for communication about the follow up and the early utility flagging making it hard to mow)....so as it is, 5 stars (rounded up). I will likely use them for yearly service, but will do due diligence as always.
