Sept. 2026: Came down the stairs one day and heard a huge whooshing sound, and I just knew my…read morebasement must have inches of water in it! Ran downstairs: nothing! Went outside...a pipe to the sprinkler system had busted because of settling or something over the past 26 years. (Go figure!) Called up A 3 in 1 Irrigation Specialists, and Nathaniel and John came out (on time, right when they said they would), and fixed the broken pipe in short order! I showed him another broken sprinkler head, and he made quick work of that too. Oh, and I needed a new bell thing, and he got me all fixed up on that also. A few weeks later I asked them to come back for 2 reasons: 1: When Rod Martin's Complete Basement Systems installed the sump pump in my subfloor, it shoots water out of a pvc tube up to ground level, then goes underground for about 20 feet before dumping out a vent thing in the yard. But the pvc was the lamest, thinnest kind possible, and going over the buried pipe with the riding lawn mower caused it to crush the pvc pipe down flat (underground, under the grass, but I could see little shards of white plastic here and there.) So Nathaniel and John laid down a new, stronger pipe for me. The 2nd reason they came is because I've been noticing that when it rains, the water does not go down the downspout and into the pvc pipe and away from the house, it just stays there overflowing right up against the foundation of my house. I had a plumber tell me about a year ago that the roots from the fir tree above the pipe had busted through the pipe, and there was nothing he could do without removing the fir tree! All's I wanted him to do was to roto root the pipe, but apparently it was too full of roots to do it, or maybe he figured it also had cracks and holes in it. So I let that go until I decided to let them remove the fir tree, because I thought it had to be removed to lay new pipe. Well, I had Nathaniel take a look, he and John dug to find the end of the pipe, and guess what? It wasn't the fir tree's roots, it was the big maple tree in my front yard! And the pvc was entirely intact! When they built my house, they ran the pvc from the downspout, to under the sidewalk, it went about 18 inches further, and then it just stopped! There was no cap on the end or anything, just good old hard Colorado clay soil. So as the tree grew, its roots found that if it went inside the pvc pipe, it would have lots of water, so that's what it's been doing for the past 20 years. Mix that with the leaves and dust that have come DOWN the downspout and into the pipe, and you have a nice big rope of small and large roots, mixed with lots of mud. So Nathaniel and John added some pipe to bring it further into the yard (additional watering for a very dry spot in my yard!), and put a pop-up drainage thing at the end, so that whenever it rains, the water comes down the downspout, through the pvc, and the pop-up thing lifts up an inch and lets the water out into my yard. The rocks around it help absorb the heavy impact of the water, until the grass grows nice and strong again, then it will fill in around the rock. And NOW those pesky tree roots won't have a way to clog the pipe again! Just look at what 20+ years of roots in a pvc pipe looks like! Like a 15 foot snake! Anyway, Nathaniel and John are my Go To guys now, they went above and beyond at every turn. Once they located all my irrigation boxes (there are 5), and by located, I mean they were covered with bark and dirt across 2 sides of the house, I mentioned that I would get some flags so that we can find them easier next time. Guess what? They quickly grabbed their flags and flagged them for me! And there was a lot of leftover dirt piled up after the new pipe was laid, and Nathaniel asked me where I would like for them to remove the dirt to. I said "Oh, I think I have an idea of where I want to put it (hidden behind one of my bushes), don't worry about it, just leave it and I will take care of it." But they would not leave a job a mess, and they moved all the dirt and mud for me, and of course replaced the sod they had to remove to lay the pipe. So like many others here on Yelp, I had a fantastic experience with both Nathaniel and John. Nathaniel is super great at what he does, and I trust his expertise, and am very happy with all the results. Thanks so much, Nathaniel and John!! :)

James came out with one other person (didn't get his name) to check that our sprinkler system was…read moreworking. They turned on the water and made some small adjustments to the heads and noted that several of the pop-up heads were not rising and lowering smoothly. He informed us that we would have to oil the heads. In addition, they noted we have 7 zones and the 6th zone was not working. However, they could not locate the 6th zone and, therefore, we do not know where the 6th zone is and if that would impact our underground sprinkler system. I was disappointed in their service for the following reasons: 1. We have a Rainbird system and Mile-Hi specialized in Rainbird (according to their website) yet, they told us we would have to oil the heads. We are not sprinkler and irrigation specialists and would think that as part of their turn-on service they would ensure all heads were calibrated and properly functioning. 2. The fact that they could not identify Zone 6 makes me wonder if the technicians that were sent out have been properly trained to work on Rainbird or any sprinkler/irrigation system. It seems now that we have to find another Sprinkler/Irrigation company to finish the job.

The job was completed in approx 15 minutes. When I went to pay him the agreed-upon flat rate written estimate of $68 in cash he said "No, it's $80." I replied I have your written estimate of $68 here on Yelp. He then awkwardly spit out, "That must've been somebody else's quote." As info, please be aware that all necessary details were provided at the time of estimate request and nothing changed between that request and the day of service; no additional services or repairs were requested and/or performed. He then demanded that "The price went up!" I advised him that this is not acceptable business, that you cannot provide a written flat fee estimate, and then attempt to gouge the customer at the time of service. As he took my money and started to leave he barked, "You can eat sh!t Mother F@cker!" I'll go ahead and state the obvious, this behavior is completely unacceptable in the world I live in, probably yours too. Incredibly shady and negative experience all around. Keep looking unless you enjoy this sort of experience.
