Castle Rock Lawn and Sprinkler is top notch. Exception service. Matt, the technician did a terrific job on our 5+ acres blowing out our irrigation/sprinkler system. They are well worth it.

Auggie came to winterize our sprinkler system today and he was excellent. He texted to let me know what time he would arrive and then performed the job very efficiently. He took the time to explain everything he had done and was very polite. I highly recommend Castle Rock Lawn & Sprinkler company.

I had Bobby dispatched to help winterize my system at my new home, and also to teach me about it and most importantly how to use it. I’ve never owned a sprinkler system and was needing some help. He was great to work with and super knowledgeable, and now I’m able to operate or adjust it myself, and know what to look out for issue wise.

I’ll also be calling Castle Rock Lawn and Sprinkler back in the spring to help me activate and optimize my system to support all of my new landscaping plans, as well as requesting Bobby if he’s available.

I highly recommend this company, and from one professional to another, it was nice to have a pro helping me out.

Matt came out to troubleshoot why I couldn’t get a zone to turn off when winterizing with compressed air. He found the problem immediately and I had him winterize the 23 zone system. He did a great job and was very efficient and used a much better compressor than I have to get the zones blown out properly and quickly. He also pointed out some things to look for in the spring when I turn the system back on. Thanks again Matt!
