Jayson was incredible this morning! I had a few issues with my last service company and needed a change. Jayson understood exactly what was needed, was extremely polite and welcoming in addition to doing a great job getting the system restarted. He identified a problem, shared with me the fix / cost, and completed the work quickly and professionally. He was great in every aspect of the service.

This company is great ! Very professional( as their name says :-) ). I enjoyed how quickly they put me on schedule and came on time, executed the work as agreed and communicated back to me with all details.If their phone system has a long wait yo schedule, wait and insist, it’s worthwhile!

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 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.

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.

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!
