5 stars! Nathaniel was responsive, professional, knowledgeable, and kind. He took the time to show us how our sprinkler system worked and addressed all our questions. We highly recommend him and would read more

The absolute best! Showed up at my house within 2 hours after I called them to help with an irrigation issue. They were friendly, knowledgeable, fixed the issue quickly and with fair prices. Also gave me other recommendations and diagnosed other problems for my awareness. Don't hesitate to contact them! read more

Read Nathaniel was a great guy who did great work and knew sump pump and underground gutter connections. He showed up exactly on time. He goes above and beyond and knows his business. He was careful around my pvc pipes and immediately found the problem. A quick repair and three way line upgrade. I'd trust him again to do work. read more

Responded the same day- came the following day to repair a broken backflow preventer. Others either didn't respond or couldn't come for 3 weeks! Fixed the issue in 30 minutes so I can water my lawn again! read more

I used A3 to work on my sprinkler system. They did a great job and I will be using them in the future. I have a large yard that requires a good sprinkler company, so I will be using them again. read more

Nathaniel came the same day I called and was able to repair multiple zones in my sprinkler system. Even found an underground tree root that was growing around a pipe, causing the issues. He also repaired a sump pump issue that could've been costly down the road. Prices are more than reasonable! read more

The business responded right away to my request and came the same day to do our sprinkler blowout. We will be hiring them again!

Had a great interaction with Nathaniel and lan to work with him again He was right on time, communicated well and did the job he promised for the fee he quoted. Can't ask for much more. read more

Outside irrigation pipe repair was well done and very professional. Would recommend again.

It was four days before he responded and then told me they couldn't fit me in. Fair enough, but then adds the comment "hope they fix it right." Just think that comment wasn't necessary and also unprofessional. read more

They scheduled me 3 weeks out; I confirmed the appointment and received a text in reply, but the tech was a no-show on the date and time of my appointment. I texted and called for an ETA; no answer from him or from the company when I left a vm. An hour after he was supposed to be here he texted that he was stuck at another job and could he come the next day. All he had to do was communicate in the first place. Horrible experience if you need someone reliable. read more

This was a quick and great repair. I had previously worked with another company who broke my manifold and quoted me a crazy number to fix their mistake. Called and got an estimated cost within 10 minutes that was much more reasonable. Knowledgeable and professional technician who came on a sunday morning to fix my situation before a key trip. I will definitely work with this company again. read more

I had problems starting up my sprinkler system and found A3 in 1 via Yelp. They had great reviews and were responsive to my request so I booked an appointment. Nathaniel just came out this morning and I walked him to the front of the house to show him where the valve is, which is in a garden bed that we just planted with transplants. I noticed he almost stepped on one of them as we were walking over, so I pointed them out and asked him to watch out for them. He got really offended and started throwing an attitude and said he could just leave if I wanted. I agreed with him and told him he should go. It was a really weird interaction and hopefully he was just having a bad day, but I'll definitely not be working with this company again. read more

Incredibly rude and unprofessional. When trying to speak to Nathaniel to get an estimate on a job he cut me off and refused to answer questions. All I was trying to do was ask questions and get clarifications on the estimate and scope of work. read more

Needed to winterize the sprinklers a little early this year. Got response within 24 hours, service was quick and great value. Got some recommendations for which sprinklers need to be adjusted, definitely going to use them next season as well. read more

Nathaniel was prompt, did excellent work and was very reasonable with his pricing given the work he had to do. I have already booked him for winterization and will not hesitate to use his company in the future. read more

Nathaniel and his two guys were great! Very efficient and knew exactly what the problem was as soon as I showed them what was happening. They got it repaired and working quickly! All for a very reasonable price. Great job guys! read more

I found through yelp due to good reviews. Had my whole sprinkler system fixed for a house I just bought. A problem popped up he came immediately and fixed it. Very satisfied will continue doing service with this company. Very professional and efficient and reasonable pricing. read more

A3 in 1 Irrigation Specialist - Came immediately to fix it. - Irrigation Near Me - Denver, Colorado

Jason showed up early and went right to work. The broken line was in the back yard and was an easy repair. Jason repaired it quickly and water was restored to the line. The cost was reasonable at $75. If I need any more sprinkler work I will call JAC's sprinkler again. read more

We had a 2:00 p.m. appointment and at 2:15 I called and learned he was on a job about 35 Mi away . He then asked what the problem was and I reminded him I had sent a detailed text with all that information . He claimed to have read it but knew nothing about the work to be done . So I explained it again and he gave me some prices, which were wildly inaccurate since he didn't seem to understand the nature of the work . I would expect the contractor to call me if he was running late and this contractor definitely did not do that . read more

Since I contacted A3 in 1 Irrigation Specialist based on reading Yelp and Google reviews, I thought I should also leave a review to share how pleased I am with their service. Nathaniel contacted me quickly and arrived as scheduled. He and his crew evaluated our needs, made the recommendation to replace our broken sprinkler valves, and also moved a few of our sprinkler heads which had been placed behind our fence so that the grass was not receiving all of the water. They also looked at our other sprinkler heads and determined they were fine, but they raised them a bit so they'd work better and feed our lawn. After performing the work, Nathaniel and his crew cleaned up. I'm very pleased with the work they performed, and I think our lawn is going to look even better now. I'd recommend and use them again. read more

Top notch service from Nathaniel of A3in1. We purchased a home in winter only to discovered this spring that the sprinkler system was completely shot. Nathaniel responded timely to our request for estimate and within weeks our new sprinkler was installed. We were always informed on the crews estimated arrival time and they completed the job on time. The crew was respectful and cleaned up after the job. Nathaniel reviewed the control system with us and helped set up the wifi remote mode. We will continue to rely on A3in1 for annual maintenance and any additions to the irrigation system. Happy customer, Kathleen read more

Charged the sprinkler system and had a leak. Contacted A3in1 and Nathaniel was quick to respond and get me on the schedule. He showed up on time and had the issue diagnosed and fixed in no time. Great communication and customer service. I will be using them again read more

Nathanial was amazing. We had a busted sprinkler head and a suspected leak. He showed up and had it all fixed within about 30 minutes. I also heard him tell another potential customer something would be a waste of money. Fantastic to see a company not doing unnecessary and costly services. Heads up though - when scheduling, when you send your address and he sends back a date - you are scheduled for that date. I was still shopping rates and was surprised when he showed up this morning. Fortunately, Nathanial was cheaper than the other quote I got and was able to get my yard fixed weeks earlier. The assumption was my fault - but I want to save someone else from making the same mistake I made. read more

One of our sprinkler heads broke and water started gushing out. Nathaniel and his team were able to come on short notice. Super polite + communicated well. He let me stay with him as he worked and was happy to answer questions as he worked (I don't know anything about sprinklers and wanted to learn a little). Part-way through the repair, he pointed out that this zone's water pressure was low: too many rotary heads had been attached to it already. As such, he proposed we switch these heads to a drip line with misters. That was actually preferred since this was a shrub area and vegetable garden. He completed the work quickly and for a fair price! read more

Very pleased with the response time and the work they did. Came when the said they would, did what I asked and quote was right on the money without any surprises!! Great company! read more

Nathaniel and his crew at A3 in 1 did an awesome job repairing my sprinkler system! From his initial reply, which was quick and courteous, to his expert diagnosis and thorough explanation of the issue, I could tell immediately that he knows his stuff. He also got his crew out here on extremely short notice, as I had a very tight timeframe to meet my home inspection deadline. The work they did was second to none, and my system is now working great after they repaired a couple of leaks. Flexible, professional, and above all they did the job right - what more could you want? Oh yeah, he was also the lowest price of any quote I received! There's a reason A3 in 1 has so many great reviews on here - I will definitely call on them again next time I have an issue. read more

After getting having two other companies come out to look at our sprinklers and immediately try and sell us a new system, Nathaniel with A3 in 1 took the time to really look at what we had. He was the only one that knew how our old system worked and wasn't afraid to try and fix it. He started the same day and had the sprinklers working for the first time in 3 years. Not only was everything fixed but he saved us a ton of cash and explained how everything worked. I'm very impressed and appreciate the work Nathaniel did. Highly recommend. read more

Not sure what happened here. I sent a message and it was responded to within 24 hours, but after that communication went downhill ending with a request to come the same day and then no further response or communication. That was a week ago and still nothing.. read more

Nathaniel came out to our house today on short notice to address a broken sprinkler line that we needed fixed right away. He was extremely thorough in addressing not only the immediate issue but also identifying problems that we had not yet noticed. We have only been in our house a few months and are encountering a lot of "DIY" irrigation work. Nathaniel ended up spending more time than we had planned but made some much needed repairs at a very fair price. We will definitely continue using his services and highly recommend to our neighbors! 5 stars!! read more

I was super impressed with this team. We had an issue yesterday and they were able to come out the very next day. Super helpful and quick. Thank you for your help!! read more

No call no show for Appointment. 20plus minutes after our scheduled appointment and no crew or call about running late I reached out to see what was going on. I was told they couldn't make it so I asked about rescheduling I got no response. read more

We hired A 3 in 1 Irrigation Specialist for fixing a leak in our irrigation system and also for winterizing it. They are professional, price is competitive and give advice on our system without trying to sell expensive upgrades. Would recommend. read more

They came out and looked at the system and let me know what's what and what doesn't work. Honest and straight forward. Will be using them in the future. read more

The quality of their work is great. Markup on new heads is quite high (charge 20 bucks for what is 6 at the store). Their communication is 0 stars. Last year I had to beg them to come and when they finally responded to me they picked a very specific time when I was unavailable. They showed up anyways despite me telling them multiple times I wouldn't be there. Then they were unresponsive when I tried to reschedule. This year I had to ask them multiple times to get on their schedule, then when they canceled because of weather, offered no reschedule date. I'm tired of the back-and-forth scheduling issues, now spanning multiple years. They do great work, they installed the system. I'm trying someone else this year. read more

I have used the company so far two times, soon to be three. Twice will be for a sprinkler blowout, and once for a sprinkler repair and turn on. A little over a year ago, I bought my house. I had no idea what I was doing and I had called a few companies for a sprinkler blowout. The other companies told me I needed to find the water valve within my house. They couldn't help me find it. When I worked with Nathaniel, he explained that the other companies obviously had no idea what they were doing. He didn't even have to enter my house. He was done within minutes. When he came to turn my sprinklers on, he fixed any heads that were either broken or over extending the water. He showed me how to operate my sprinkler system and how to get it adjusted to specific watering times and days. I thought the price was fair. I know not all the reviews are positive, but I will continue to recommend this company and Nathaniel Based on the great service I have received! read more

Great service. Nathaniel cares about doing things right and taking care of customers. Highly recommend!

Nate has done two different properties for us and he and his crew are outstanding ! Always on time and very professional. I will use his services moving forward and long into the future. He provided solutions to a few problems that we had from a previous and not a very good landscaping experience. read more

First of all, there needs to be a little context as to how we came about hiring A3in1 Irrigation Specialists. Last year we hired a landscape company to come out to our house and repair our front yard sprinkler system which had been severely damaged by the uprooting of a large evergreen tree a few years earlier. The guy came out and replaced the manifold, the valve box, and installed a one zone, battery operated valve timer and control. I asked him how much he would charge to put in two completely new zones in the front to replace the damaged 1975 zone that were ripped up by the tree. I thought the price he quoted was really high so we passed on that work. I had him come out at the end of the season to turn off and drain our system. He did that well and placed a seal on the back flow valve and said that if it was removed his warranty for the blowout, was void. He said he would call in the Spring when it was time to turn everyone's sprinklers on. We did not hear from him again. I sent him a text and an email message on April 27th which I received delivery confirmations on both. After hearing nothing I asked a friend, who knows him, to find out when he was going to turn our sprinklers on. She said he told her that he had not heard from us. I doubt that his email and his text messaging both failed on the same day. Even stranger I had delivery confirmations on both. We began our search for a new sprinkler person, since our current guy was totally unreliable. We called about 6 companies and left messages for quotes to turn on our system and check a few sprinkler heads that were not working. Four companies did not respond at all and two said they couldn't do anything until late July. I looked on my Neighborhood web site and found a number of good reviews for A3in1 Irrigation Specialists. I called them and left a message. Within an hour or two I received a callback and I told them that I needed my system turned back on and a few heads checked. They asked me to send them a text with my name, address, and what I needed done, which I did. Within about a day I received a reply stating that Nathaniel would come to my house on May24th between 10:30 and 11:30 to check out what I needed. On the 24thNathaniel showed up a little before 10:00 AM. By that time, I had figured out how to turn most of my system back on with the exception of the battery controller installed last year. Nathaniel turned on the battery-controlled zone and checked the heads. He said that there were too many heads on that one line (I suspected that all along). He said that he could fix that by replacing the heads with lower pressure heads. I agreed to that fix. In the meantime, I asked Nathaniel how much he would charge for adding the two new zones I wanted to replace the destroyed zone and then to add the new zones and the one he just repaired onto a controller on the side of our house. He told me the cost, I agreed to it and he told me it would be several weeks but it would be scheduled that day for a Saturday in the near future. When they turned on the newly repaired zone with the new heads, I noticed water bubbling up between the foundation for my garage and a concrete walkway right next to it. It turns out that the guy from last year who was out to fix our system and installed the battery controller had missed a branch line for an old sprinkler that ran back to the corner between my garage and my fence. Nathaniel said they would find that rogue line and cap it for me. After some digging without any luck Nathaniel suggested that they go ahead and install my two new zones that day. He said that he could not in good conscience leave me with a leak like that because it would eventually destroy my concrete. So, Nathaniel made a few phone calls and he and his helper installed the two completely new zones, replaced the old manifold and valve box with new valves, manifold and box, Disconnected the rogue line that was leaking, installed a new Controller that now controls all the zones from a central box and with WiFi control. Everything was buried with the sod back in place and running by 7:00PM. The new system that he installed including the WiFi controller is great. Everything works perfectly. We could not be happier for the wonderful work that A3in1 did for us. I was most impressed with the fact that they stayed all day and fixed the problem that I had with the leak. Nathaniel always returned my text messages, showed up on time, did the work in a timely manner and most importantly did exactly what he said he would do for the amount agreed upon. I would recommend Nathaniel and A3in1 Irrigation Specialists to anyone needing any form of sprinkler or irrigation work. read more
