    What our clients say about our work

    • I was the super of an apt complex in Oakdale. It was always a problem for me to find a reliable and talented irrigation company to help me when I had a lawn sprinkler problem. When I found McCormack Irrigation it was like an answer to a prayer. When I called them asking for service they’d respond almost immediately and their repairs were 100% professional. I highly recommend this company.

    • My family and I have been customers of McCormack Irrigation for over a decade and we are extremely pleased with the results. Your company provides quality service, fair prices, and your customer service skills are outstanding. Dealing with a family operated business that treats us like an extension of their family has been beneficial and we intend on remaining a loyal customer for years to come. Thank you and keep up the good work!

    • What can I say about McCormack Irrigation…I love them so much I’ve used them 3 times!! I am glad to recommend them and have already done so to friends, family and even my mom! In a world where so many people/companies don’t do what they say they are going to do, I am glad to know that my friends at McCormack are dependable, trustworthy and honest. If you are looking for the right sprinkler company, you’ve found them.

      – Paul W. Fort Salonga, NY

    • I have used McCormack twice for two homes. I have always found them to be reliable and their system has held up over time. I am writing this 13 years after my initial installation and I have had my first problem with my system (cracked manifold). They scheduled the repair quickly. I consider McCormack a company I can rely on.
