Professional Irrigation System has a great technician in Jayson Salvador! Jayson arrived at my house to get my irrigation system up and running for the spring start up. He arrived on time, and with a smile on his face! Jayson is was friendly, and was very accommodating at tweaking some of the sprinkler heads exactly how I wanted them. I needed one more sprinkler head added to my system, and Jayson installed it, and had it up and running 20 minutes! Thank you Professional Irrigation for sending Jayson! I would recommend Professional Irrigation Systems to everyone!

Professional Irrigation Lawn Service performed our lawn aeration, overseeding, and application of a top dressing yesterday. The two young men were very proficient when performing all of the services and carefully avoided irrigation heads when aerating. I was particularly impressed to see them apply top dressing by hand when they were close to hardscape. That’s what I call “attention to detail.” Upon completion they used a blower to clean up top dressing and any seed from all areas. Last but certainly not least, Sierra in the office was such a delight to deal with. Polite, respectful, and always going the extra step to put the customer first. Having spent over 25 years working for the Army I quickly recognized a well trained veteran, probably a Non-Commissioned Officer (NCO). She even called us just before departing on Friday to tell us the lawn service would be performed on Monday. Kudos to Professional Irrigation for a job well 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.

Even though they did hit my Internet lines they made it right and gave me next seasons open/close for free. The install was amazing and only needed a couple adjustments on the spray pattern after.

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) as it is, 5 stars (rounded up). I will likely use them for yearly service, but will do due diligence as always.

Everything has been amazing. Great pricing, financing options, and all the stuff are super helpful. I was recommended by someone and they haven't disappointed thus far. We should have our sprinkler system in just a few weeks!
