Best Sprinkler System Installation in Denver CO

Derrick was fantastic. Was able to squeeze me in and got everything working and properly set up. Answered all my questions patiently which was great because I've never own a sprinkler system before.  Really appreciate his attitude and work.

Quick and Efficient and reasonably priced.  We will be using Pro Irrigation moving forward.

I called Khan out twice. Once to replace a garbage disposal. He charged a reasonable price, but he was done in 15 minutes because he said he was in a rush to head to the airport. My understanding is that garbage disposals should take at least an hour for professionals to replace, but nevertheless, the garbage disposal seems to work fine for now.
Now, the sketchy part. We had a pipe burst in the main water line, and water flooded the basement.
He told me he also does restoration for water damage. He left us a quote for over $7,000 for water restoration and said we had to pay 50% upfront. The other water mitigation company ended up only charging us about $3,000 and required no upfront payment; they billed the insurance company directly.
Regarding fixing the water leak, I called two other plumbers, and they and the water company agreed that we needed to excavate 6 feet of dirt in order to replace main water line. When Khan came out, Khan did not seem to know what he was doing. He mentioned going into the basement to try to find where the leak is and working from the basement. I wish he was more upfront about not knowing what he was doing. I would not use him for more sophisticated plumbing jobs.
I really wanted to like this guy and default him as our main plumber for our plumbing needs, but in the end realized I can't trust him to do our plumbing work for our properties.

Dan's Sprinkler goes above and beyond. Customer service with a sense of humor. I was let down by a large firm in Denver and Dan came to rescue. Dan came on a Saturday to fix breaks in copper pipes to back-flow. He is extremely busy like everyone else but he cares. Thanks Dan.

Turned on my water and my backflow had some mysteriously vibration.

Technician came out - said it was more for a plumber to fix. Which I did.

But he also took the time to educate me about back pressure / appropriate operations - which fed into my conversations with my plumber.

Bottom line - for the honest assessment / knowledgeable staff / easy to work with - these guys have earned all my irrigation business.
