"Outstanding service! Our local lawn sprinkler unexpectedly and without warning stopped providing service, and we were left stranded. I reviewed new candidates and selected Greg Tanzer. Couldn't be more pleased. They were extremely responsive, informative, professional, and very affordable. We will be switching our business to Greg's business."

"An amazing experience for my landscape lighting. From sales to scheduling to installation... All around a terrific experience and one that we’ve become used to with Tanzer. In the past, they've installed and modified our irrigation to perfection as well. The installers didn’t make a complete mess of the property, especially when they were digging the trenches. The sod was put back nicely, which is a HUGE deal for me. And they took their shoes off to go into the basement after working in mulch, grass and dirt. If you're looking for a landscape lighting and/or irrigation professional, they're the BEST!"

"I was having  a problem with water leaking out into the yard from an unknown source. Called several companies (I open the system myself) who said it was probably a defective valve or leaking manifold causing the issue. I asked for a ball park number which ranged from $200 to $325 "depending on what would have to be replaced". I called Quality Irrigation who took the time to ask specific questions on the phone. He came up with the same diagnosis but said with any luck it may be repairable without taking apart the manifold. He came out the next day, literally took the valve apart to find that a stainless steel nut was stuck in the diaphragm causing the value to slow leak and flood the yard. He reassembled the valve, boot up the system and it worked like a charm. He charged me just for his time, $85. I now have a new sprinkler service company! Thank you..."

"Everything was great from start to finish. From the office staff to installation team. Everything was seamless. They came when they said they would and produced the result I hired them for. We had multiple lawn zones and planting bed zones installed with Hunter product heads. Our water pressure was on the low side so with the advice of Joel went with a newer style mist combo rotor head to combat the pressure issues. When everything was installed and the team was cleaning up, Joel programmed the sprinkler system timer to an app on my phone and taught me how to use it. I can turn it on and off no matter where I am and can edit all settings from my office or while away on vacation. This new technology makes everything easier and more efficient. Couldn't be happier with the results!!!"

"The job went great! Prior to installation of the irrigation system, Jimmy worked with my landscaper to ensure the new sod and planting beds we were having installed would thrive. The crew showed up at the agreed upon time and were very professional. The supervisor came by to make sure everything was going as expected and was available to answer any questions we had. They came back to our home two weeks later for a two week follow-up. The technician walked us through the system step by step (again) and made necessary adjustments. Unfortunately, a week after our 2 week follow-up visit we discovered an area of our new sod that wasn't getting enough water. All County quickly responded and sent another technician back to our home to adjust the necessary sprinkler heads. We couldn't be happier with our new irrigation system and would definitely recommend All County Irrigation to anyone looking to make their lives easier by installing an automatic sprinkler system. "

Lawn Irrigation FAQs, answered by experts

Reseeding your lawn can help eliminate thin or patchy portions of grass. If you’re paying a professional to aerate your lawn, it’ll cost you an additional $50 to $80 on average to reseed it  in the same trip. Reseeding a lawn yourself can cost between $500 to $1,000, meaning you’ll probably save time and money hiring a professional service. 

No, watering dead grass will not bring it back to life. If the grass on your lawn is truly dead, no amount of water will bring it back to life. However, some methods can bring dying grass back to life. Consider aerating, overseeding, or analyzing your soil to get to the root of why the grass is dying. 

Whether or not grass will fill in bare spots itself depends on the type of grass you have. For example, grass with rhizomes (e.g., Bermuda grass) and stolons (e.g., Saint Augustine grass) will naturally fill in bald spots as it spreads laterally. However, clump-forming grasses will not spread. 

Properly preparing the soil for planting grass seed may include applying fertilizer several weeks before spreading the seed if you plan to overseed the lawn. However, in most cases involving a brand-new lawn, spreading a starter fertilizer along with the grass seed will give it the best chance of taking root quickly and growing strong.

Wait at least three weeks after overseeding ryegrass before breaking out the lawn mower. Mowing sooner will tear up much of the delicate, newly seeded ryegrass as it won't have established strong roots to anchor it yet.
