Collin G did my start of season work. This is the first start up sin during installation last year. He helped with my “mostly a beginner “ types of questions. He also helped me block some days leading into sod installation. He was very knowledgeable and very helpful. He also showed me how to extend spray to areas at the property edges to help new seed and sod grow. Very good!

I had Professional Irrigation out to add two additional sprinkler heads to an existing system and the gentlemen did a fantastic job. They were pleasant, personable and professional. The work was performed without hassle and done in a timely manner. I’ve also had a good experience with customer service with each interaction.

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!

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!

Added an irrigation system to a 50 year old home. The irrigation system was installed in April but I waited until now to post my review so I could evaluate all aspects of their company. I researched companies and invited my top three choices to bid for the job. Pro Irrigation wasn’t the least expensive but their bid was in my reasonable price range. I am impressed with the professionalism of the three main customer facing aspects of their business, sales, installation, and service. I appreciated their commitment to complete the installation in one day. After the recent service call, I have the system that I wanted that covers my entire lawn (front, back, and sides) and all the flower beds. I like the Wi-Fi enabled controller that I’m able to manage with my smartphone. No more lugging hoses around my very large yard or hand watering all the plants.

Another great experience with Professional Irrigation. We've used them a few years now, after trying to save money going with another company (since closed). I'm always notified of appointments in advance, work is great, techs who come out have always been skilled and informative. I had Tyler today who provided me with options to fix a sensor, I went with purchasing a new one to ensure there were no issues since I know the company backs up their work. Wish all companies did what they said like Professional Irrigation. Thanks!
