Landscaping reviews in Denver, Colorado

My house was built in the 60's and the sprinkler system is very old. I was unsure if it could be revived but thanks to Nick & his dedication and knowledge, he was able to bring it back to life. I would highly recommend Mile-Hi (& Nick) to anyone requiring this service.

Great communication and service! Our sprinklers were down -- Stan and Connor figured out what was going on, got the repairs taken care of, and went the extra mile to make sure the system was running smoothly again!! They were efficient, easy to talk to, explained things well, and made us feel very confident in our decision to go with this company! Thank you!!

Stan and Connor were fantastic! They redid the entire sprinkler system in my front yard and made the whole process easy from start to finish. They offered helpful recommendations, explained everything clearly, and got the job done quickly and efficiently. I really appreciated their professionalism and attention to detail. Would hire them again in a heartbeat.

Jax and the scheduling team were awesome. We bought a house and couldn’t get the sprinkler system working. Called Mile Hi and they were able to send someone out the next day who was able to get it up running in the first 10-15 minutes. It’s been really hot here all week so we appreciated their ability to get here quick, give us pricing up front (pending what work would need done), and have us running again so quickly. Will definitely use them again. Thanks!

Dylan showed up 30 minutes earlier than planned and still was able to get our sprinkler system winterized and done in no time. Super convenient and quick - would definitely recommend!

My sprinkler system is a bit challenging to figure out, but Jax did it!! I have an extra special thanks for him for closing the doors and turning off the lights after working downstairs. It is unusual to have such a thoughtful, conscientious worker in our home.

My sprinkler system valve manifold developed a leak that I could not repair on my own. Mile-Hi Sprinkler came out to give me an estimate, and it was very reasonable. I could tell the guys who came knew what they were talking about, and they didn't propose any unnecessary, additional work. I appreciated that I was able to converse with them easily about the situation. There were no language barriers.

But what made me particularly satisfied was that they were able to come and do the work the very next day once I accepted the work estimate! I was quite surprised how quickly and easily they were able to do the work. They were careful about not damaging any of the surrounding landscaping and they cleaned up the site very nicely.

I am always very satisfied when I find a company that does good repair work. Especially when I can see that they did a much better job than I could have done. I will definitely work with them in the future.

Love these dudes! Very professional, reliable, and efficient. I'm going on 8 years of using this company for sprinkler blow out. Definitely recommend!

Arturo Perez and assistant of Mile-High Sprinkler were quick and efficient and blew out all stations of my sprinkler system. Good service and also took time to answer my questions.

We moved into an old house and needed a sprinkler system and sod. Mile Hi had a small window of time between jobs to squeeze us in, and for half of what others had quoted. They constantly checked in in the days leading up to the install, and showed up at 8am as promised and went straight to work.
They installed a control box in a spot we didn't love, and since this is for the long term, they moved it where we preferred in no time at all.
The team was 100% professional, smiled all day, cleaned up after themselves, went over the system with us and made sure we were completely happy. And they did it in 6 hours. The full sprinkler system and sod.
It would have taken me a month.
I cannot say enough about them. Amazing.

I cannot recommend this company enough. When I call to schedule an appointment, I always reach someone immediately—no long wait times. The receptionists are consistently courteous, articulate, and welcoming, setting a positive tone for the experience. The technicians arrive promptly, are respectful, well-informed, and transparent in their dealings. Plus, their pricing remains remarkably reasonable, reflecting their commitment to value and integrity. Overall, a truly outstanding service provider.

I have hired Mile Hi Sprinkler for several jobs, and they never let me down. Always on time, always expert advice, never pushy with a sale or quote and always respectful of my property. I don't trust anyone else! They have upgraded our Greenlawn valves and repaired so many units at my home. They put the grass back in place and all I have to do for repair is over seed. I honestly have never seen such efficient, respectful, hardworking people in my life, the work is done quickly, typical under quote and always done right. They are honest and will fix any problems!

On time, professional and friendly service. You can always count on Mile High, they’re consistent! And fair pricing!

Great company. I got my system installed two years ago and, since then, the owner (Mike) and his staff have been incredibly helpful. I have called them a few times to get new heads, start and stop the system for the winter, etc. Each time they have done everything they can to help.

Marcus and his apprentice, Anthony, came to our house this morning to help us fix a machine-like, loud, rather scary sound that was coming from our sprinkler system whenever it turned on. The problem was due to very high water pressure, an easy fix which Marcus enabled by moving the ball valve on the outside backflow system so that it wasn't fully engaged (see picture below).

Marcus also gave me a full tutorial on how to set, run, and modify the zones via the sprinkler box downstairs. He is an exceptional teacher, enthusiastic, knowledgeable, and personable. I learned a great deal and highly recommend him and this company for other people to try out.

Mile-Hi Sprinkler recently installed a new irrigation system and sod at our home, and we couldn’t be happier with the results. The team was professional, efficient, and easy to work with from start to finish. From the initial bid through project completion, they were attentive, proactive with scheduling, and made sure everything went smoothly. We’re thrilled with the outcome and would gladly recommend Mile-Hi Sprinkler to friends and family.

Nick and his team were absolutely wonderful to work with for my sprinkler installation. Communication was excellent and they did wonderful work. I’m so glad I found them!

Also, they didn’t ask me to review them which I think means you can really rely on the reviews here ✨

10/10 would pick this team every time.

Had the crew out to install a new system. Less than 2 hours and a perfect job done. I have been in construction for 36 years and I would recommend them to my friends and family. Thanks so much for caring about doing a good job for a fair price.

We are impressed with how quick and efficient Javier was with our new-to-him system. They took care of us and our system lightning fast! So glad we found Mile-Hi Sprinkler!

Love the customer service! Jeremy, such a nice young man, winterized my system quickly and professionally! Definitely, am looking forward to doing business with them in the future!

I sincerely appreciate the reminder and notifications of when to expect the technicians with the four hour time frame. That was very helpful in planning my day. Once they arrived, they were very efficient and quickly got the job done.
