Automatic Irrigation Design is New York's oldest and largest lawn sprinkler company. We have installed thousands of residential lawn sprinkler systems all across the tri-state area. We specialize in new installations, revamps, closings, openings & rain-sensors. We have earned an impeccable reputation for service, quality and competitve pricing.

"I got sprinkler system installed in summer of 2020 and the initial team did a fantastic job. They were professional and knowlegeable. I often called once or twice per year to get tuned up. The guy they usually send, Steve, was always very unprofessional and always in a rush..but he's just there for tune up so what? In november -december of 2022 I called Automatic irrigation design frequently, keeping them up to date on a project I would be starting, which would involve moving a few of the sprinklers further back to do an extension. Steve came out several times and always made excuse about not being able to do something, or why the job cant be done. Finally he came out on 1/30/23 to move and re-run the water lines to the sprinkler main box. My contractor didn't want to have anything to do with touching the sprinkler system nor plumbing to prevent the issue i am having now. I updated Automatic Irrigation System on everything, asked their opinions and agreed with them on when to do what. I paid $754.94 to have this new main run. When my project was finished in March, we called them back to reconnect and turn on system to prepare for spring. Again they sent Steve, and as usual, within 5 minutes of being there he started shouting that its a bigger job than he thinks, and that he cant do it alone, because the sprinkler valves were damaged and blocked by the contractor. He tried to explain that when the contactors were doing their plumbing they might have gotted sauder dust in the system blocking the valves. Only probem is, Steve was the one who ran the pipes from the old building to the valve box. He and my contractor had a back and forth about who did what, while I have to finally come up with the funds to get my system fixed. This happened in March, and today May 16th, they have not been back to repair my system, even though I agreed to pay the $950, plus what ever issue come up after they are done with the job. Debra , the office clerk at first seems ok. Later I found her to be rude and unprofessional. First, they gave me a 6-weeks date for service, after the damage was announced. Each time I called..she would pull Steve into our conversations ( and for some reason, Steve is always in the office as busy as they say they are...9am, 11am, 2pm, 4pm, he is always there). My final call today was to request an earlier service date as my newly laid grass was drying out and dying from lack of water. Why do I have to suffer anymore, when we have been going at this since december/november. Debra became upset when I mentioned, that even though it could be Steve that cause the damage, that im willing to pay for, they were not even showing common courtesy by trying to work with the customer. Instead, she put Steve on the line, and after several minutes of me and him going back and forth ( where he stated, "how can you blame me? I blame you for digging up your yard before calling us." (That was a total lie as I mentioned before, that i kept calling them every step of the way, asking them what they needed to do, and working with them. They did nothing to show loyalty, they were not apologetic, and they did absolutely nothing to de-escalate the situation. Debra tried to get me to stop talking, after having difficulty getting Steve to stop shouting at me. I could not believe I was a loyal cutomer to a company that was rude, disloyal, defensive and watented to take no responsibility for their part in destroying my 2 year old sprinkler system that was working quite fine before Stee made the cahnges and did his saudering, without blowing out the pipes. Still, I have no prove who did what. But my plumber /contractor was willing to go half with me to get the system up and running. Even though I was not asking , AID offered nothing. All they did was gave me a date of May 28th..6 weeks from problem...and had Steve in the office cursed me out on 2 separaste ocaasions. The one star i gave this company is for the work the guys did initally in 2020. Overall service, especially customer service, 0 stars."

Lawn Irrigation questions, answered by experts

Both aerating and scarifying your lawn can offer serious benefits. Aerating pokes holes in the soil to better allow air, moisture, and nutrients to permeate while scarifying removes the buildup of dead plant matter at the soil’s surface. Most lawns require both of these maintenance items to thrive.

The best way to fix a lumpy yard depends on the cause. However, in many cases, you can address yard lumps by improving the health of your soil and turfgrass. Choose grass varieties that are best suited for your area and look for disease-resistant varieties. Fertilize and water your lawn as needed to keep it looking lush throughout the warmer months. Mow your grass at a height of 2 to 3 inches once or twice a week.

Strange as it may seem, poking holes in your lawn can do a great deal to help the grass grow back stronger, thicker, and happier. By allowing light, water, and nutrients to penetrate the soil, the grass can root down deeper and get more of what it needs to thrive. All of which is to say, if you care about the appearance of your lawn, yes, lawn aeration is usually worth the money—especially since it’s not that expensive.

No, it's not a good idea to put grass seed directly on top of dead grass. For successful germination and growth, grass seed needs good soil contact. To prepare the area, start by removing the dead grass using a shovel or a sod cutter. Then, loosen the soil, add soil amendments if necessary, and spread the grass seed evenly. This allows the seed to come into direct contact with the soil, promoting better germination and establishing a healthier lawn.

Yes, you can overwater your grass. Depending on your climate, it could be easier than you think. While water is an essential element for lawn growth, too much of it can actually damage its roots, leading to rot and other damage.

Whether your drip irrigation system leaks, it’s been a rainy summer, or you use the sprinkler too often, overwatering your lawn can drive up your water bill and impact the longevity of your lawn.
