Customers testimonials

I had a recent incident where another company caused damage to my irrigation system. Will and his team helped get the issued resolved and were very helpful with information to share with the company that did the damage pointing out where it was and the probable cause. Not only was my system fixed quickly and running better than ever but I was able to get the damage covered by the other company. I really appreciate the patience and great work I received from Koster Irrigation.

Koster irrigation is the BEST! Will and his team are so good at what they do. Will is very responsive and cares about your project and continues to improve upon anything that is needed to make your system the best it can be. They do both irrigation and lighting at fair and reasonable pricing. I have had many homes and Koster Irrigation has been by far the best irrigation/lighting company we have ever had help us. You will be happy with their work and that you chose them!

Koster Irrigation provided excellent service on the repairs/maintenance of our residential sprinkler system. I was contacted promptly within 24 hrs after leaving a request for service, and the work was performed within 5 days after my request. Technician arrived promptly to the minute I was informed he would arrive, and upfront explained how fees are determined, so that there would be no misunderstanding on an Invoice amount. Tech was professional, polite and left the sprinkler system in perfect running order. He offered maintenance tips I could easily do to avoid unnecessary problems. Lastly, and although some customers may think otherwise, we appreciate the Invoice being sent promptly by email. I was well satisfied with the work and the amount of the Invoice. Koster Irrigation is to be commended for having established a well-run business.
