BEWARE. My father used Black Rock to replace his sprinkler system 2 years ago and within the first year of install, multiple leaks occurred that Black Rock refused to repair. Within the past two years there have been almost a dozen leaks - again, Black Rock refused to address. As a result, my father has had to hire other companies to repair leaks caused by poor and faulty installation by Black Rock, along with astronomical water bills as a result of the leaks. read more

Steven Black and Bailey Black took our deposit of $1,200 and then failed to communicate a scheduling date and failed to respond to our emails and calls. We went ahead and used an alternate sprinkler company and they have refused to refund our deposit. They have refused to call us or answer our phone calls or emails. We have sued them in small claims, but they refuse service. Their "office" is out of their home. DON'T HIRE BLACK ROCK SPRINKLERS. They do not have morals. read more

My sprinkler startup technician went above and beyond to make sure my irrigation system was operating correctly. I'll be doing business with them again. read more

Black Rock installed my sprinkler system 12 years ago. They have been doing my opening and closing of the system since. They do great work. They have noticed broken sprinkler heads while opening the system and were able to fix them the same day. My neighbor was getting a new sprinkler system April of 2026 and got many quotes. She went with Black Rock based on my experience with them and the great price. read more

Fast and on time service. Had a hard time getting ahold of them on the phone to schedule. But the service was done on time.

This company advised me that they were coming out to shut my sprinklers off on Saturday October 11, 2025, and no one ever came, nor called me. While at church on Sunday, a Technician from this company showed up at my residence, without asking me for approval, but my wife refused their entry. read more

Always a good job for me. Scheduling is easy, service is prompt and costs are reasonable read more

Would not recommend. Made appointment, was not given specific time of day. Contacted office midday and confirmed appointment. Tech was a no-show. No contact from office or tech to explain/apologize. Disappointed. read more

Black Rock installed our sprinkler system. They were very professional and attentive. They made sure I understood the system and how to work it. The minor issues I've had over the last few years since having it installed, they've come and taken care of it right away. I would highly recommend working with them. read more

Very dependable, reasonably priced including repairs on aging individual sprinkler heads. Highly recommended.

Black Diamond installed our system several years ago and it has worked very reliability. Tree roots have caused PVC tubing punctures and leaks a half dozen times and all repairs were completed by BD at a resonable price and quickly. While blowing out the system last fall I noticed mist blowing up through the sod and close to a sprinkler head. I'll be calling them in a week or two, to do a repair. read more

Black Diamond installed our sprinkler system several years ago and we have had no issues. We have used them every fall and spring since the system was installed to keep us up and running. They have always been professional and efficient when dealing with any appointments. read more

Avoid this company. They were great when I used them a few years ago for winterization, but something has changed. They are tremendously unreliable and non-responsive to calls/texts/voicemails. They blow off appointment dates without any notice. When I finally said enough phone tag and called another company, Black Diamond threatened to send me to collections for a service call invoice that they had never sent to me. I had been trying since early May to have Black Diamond move a valve box so I could have some brickwork done. When they came out in May they said they did not have the correct materials (PVC) and would need to come back out. After multiple calls from both myself and my landscaper, they would give a date and then never show up with no notice. We tried multiple times throughout June to have them come evaluate where to put the valve box and if we needed to move any other lines. Nothing - No Call No Show. Finally showed on June 27 but again didn't come with the correct materials (PVC.) Spoke with them on the phone and scheduled July 1st, and they said I'd get a text message the day before to give the estimated time window. I never received a text, then July 1 came around and I didn't receive any call or text or notice, they just didn't show up again. I tried calling the office and it went to voicemail. That's when I said enough and just called another company. The other company came out and did the work within a week. Over a month later, July 28, Black Diamond calls me to say I'm their next stop to get that work done. Completely surprised, I told them no, you never showed up to do the work. That's when they got extremely defensive on the phone arguing with me about it. That's when they ran out of things to say and started accusing me of not paying my service call (from when they came out on June 27) and trying to make it my fault for not calling the office again. He told me they'd send me to collections over a service call invoice they never sent me. I've paid this company on time 4-5 times over the years, and suddenly I'm being treated like a thief. I paid the other company almost $3k (which would have gone to Black Diamond if they were more professional), I'm not trying to cheap out of a $63 service call. But if you're not going to answer my phone calls, or send me the invoice so I can pay it, how would I pay the service call? It makes no sense. Completely unacceptable and not professional in the slightest. I've never lost my cool with a contractor prior to this. I would NOT recommend Black Diamond for anything. Save yourself the hassle and find someone else. read more

Only the best! I have used Black Diamond for a decade now. That's because they are such a great family business with excellent, responsive, customer service. They installed my 11-zone system, and I use them for the rare repair from damage by lawn mowing, etc, and for my annual Winterization. I can always count on timely and kind service. Trust them with your property! read more

On time friendly service always great knowledge and rapport you can always count on Black Diamond to get the job done

Called to see if they could do a last minute spring start-up and Alex did a fantastic job. Very pleased and will be calling in the fall for winterization. Thank you for a job well done. read more

If you are in at the market for a new irrigation system for your business or residential property, DO NOT USE BLACK DIAMOND SPRINKLERS. This company has no integrity and does not stand behind their work. Extremely poor product installation and the owner of the company Steve is unresponsive unless it involves payment. I hired this company in May of 2021, this ordeal is still going on as of July 26, 2021. I should have took it as a flag when they sent a text photo of the quote. However my family member had dealt with this company, so I contacted them for the install. I told the owner that I was having new sod laid and asked which should I do first, the sod or the irrigation system. Steve the owner said Sod because they knew how to move it to lay the lines. Forward to install, they completely ruin my sod and did a extremely sloppy install job. I called the owner steve and told him the unit was not coming on, he came over and ran a manual cycle and assured me that the sprinkler units were working. I went on vacation and came back to a horridly damaged lawn because they sprinklers never came on. I have been calling for three weeks to his office and calling an texting his cell phone all going ignored. I now have to pay to have my Sod replaced again. I implore you not to use this company for any of your lawn sprinkler service needs. read more

This company is terrible when it comes to customer service. I have been a customer for the last three years and every year I have had to repair my sprinkler system due to problems associated with winterization. The last two years I paid for the repairs but this year I asked the owner to pay for the repairs since this is a pattern. He stopped responding to my text and stop returning my phone calls. Very unprofessional I cannot believe he would let a customer of three years be treated like such.I am terribly disappointed but life goes on. I will not beg anyone to take my money. read more

I've used Black Diamond for my primary house and rental properties several times over the past couple of years. Perhaps a bit more expensive than some other companies but the work and communication has been top notch. read more

This has been the most unprofessional administrative staff I have experienced. Not only are they rude and unprofessional on the phone, they attempt to charge a $25 fee that is not disclosed at the time of the appointment. The law states you must notify a customer in writing of said charges. I was going to be a new customer but not after this experience. Think twice. read more

Amazed these guys are still in business. I contacted them to do my spring sprinkler start up; my usual guys were backed up and couldn't get to me for 3 weeks. The lead guy on the job was EXTREMELY aggressive - and not terribly competent. They eventually ended up calling out 2 more guys because they were having trouble dealing with the pump. Fast forward 4 hours when they reported the job done. A start-up! Next day I went out and, lo and behold, the sprinklers weren't running. I had to call in another company to un-bleep what they did. And then, they sent me a bill for $900!! For a start-up!! That didn't work!! Stay far away. These guys are incompetent, dishonest or (most likely) both. read more

Exceptionally poor customer service and disregard for our time and plans. I called up Black Diamond last week to get our sprinklers winterized and got an appointment for 7:30 - 8:00 am this Wednesday. Wed comes around and I'm home at 8:15 still waiting for Black Diamond, when I should be on my way to work. I call their mobile number and get the same person I set the appointment up with 3 days earlier. He says he has no record of the appointment, even though I wrote it down on our calendar when we last talked along with his name, date & time, and he got detailed directions to our house. No apology from him however. He does say he can make it back out to our neighborhood at 6pm the same day. I decide to give him another chance as it might have been an honest mistake. Later on Wed, I leave work earlier than I would have to be home before 6pm. 6:30 comes and goes, and no techs at the house. I call their mobile number and get the same guy I talked to each time so far. He comment: "Yeah, I'm not gonna be able to make it out today. My other appointments took too long." No apology. I ask why I didn't get a call if that was they case, as he has our home and mobile numbers. No answer. I tell him I went to work late and left early to meet him twice in one day, and he didn't even call to let me know. Still no apology. I decide that this guy obviously has no respect for my time or my business, so when he suggests that he will be in my neighborhood again the next day, and that we can try again, I tell him not to bother. None the less, the next afternoon I get a Voice-mail that he is on my street and "killing time" until I come home. I decide to not bother calling him back. Figure he can wait on me for a change... They had the lowest cost for winterization I found, but had the business sense to match. Avoid if at all possible. Not one "Sorry" to date. read more

About ten houses in our sub had, as a group, scheduled Black Diamond to come out and winterize our sprinkler systems on Saturday 10/21/2017. They were a no call, no show. They will not be getting my business in the future. read more

Black Diamond Sprinklers installed our sprinklers several years ago and they work well. Over the years I had repairs done (leaks that occurred from root punctures to shovel cuts) and have always been satisfied with the repair and the cost of the repair. I have no problem recommending them. read more

One star is too many for this company. Questionable billing practices. Company claims they have unpaid invoice for work done on my system, from two years ago. This is the third time they have changed a price and invoice on me after I have made payment. DO NOT use this company. Very unorganized business, much better companies out there. read more

I've called on July 28th to get a estimated for a sprinkler repair. The set up a appointment for Thursday Aug 4th. They never showed or called. Mistake I made is I called and set up a new appointment for Wednesday Aug 10th. The appt time came and went, I've called and learned that there will be a $45.00 service call for an estimate. I reluctantly told them to come and they never showed. Just bad business practices. FYI. I sent them pictures of the repair many times and they said they never got, I even sent while I was on the phone with them. Not a company I would want to do business with. read more
