"Original date of installation was Thursday, June 11. They called me to inform me that an opening was available on Monday, June 8. I took it. They came within the window they provided for installation. They did an outstanding job. It was very professional. They worked clean outside and inside. It was almost difficult to tell that the system had been in stalled. The grass was replaced so that it was difficult to see where the ground had been dug up. The whole crew was very polite. Once the system was installed, the team leader instructed me on how to use the system. The next morning the sprinklers came on and worked exactly as they were supposed to. The six zone, 25 sprinkler system watered every inch of my lawn and all the shrubbery and flowers around the house. My wife and I are very pleased. We would rate them A+ if we could. We certainly recommend them for anyone who wants this system put in by a great professional organization.

"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..."

"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

It costs $1,500 on average to hydroseed a 1/2-acre lawn professionally. DIY hydroseeding costs about $300 to $500 for the machine rental, plus the cost of your seed, mulch, and fertilizer. Often, it makes sense to hire a local lawn seeding service to hydroseed for you to ensure the best coverage and growth.

The best time to plant grass seed depends on your local climate and whether you have cool-season or warm-season grass.

For cool-season grasses (like tall fescue), the ideal time to seed is late summer or early fall (typically August and September). During this period, the soil is still warm from the summer, but the air is cooler, creating optimal conditions for germination and root establishment before winter. There is also less competition from weeds. Spring is a secondary option, but cooler soil temperatures, the risk of a late frost, and less time for the grass to mature before summer heat can make it less successful.

For warm-season grasses (like St. Augustine), the best time to plant is from late spring through mid-summer (typically May and June), when temperatures are consistently between 75 and 90 degrees Fahrenheit.

In general, it is best to avoid seeding during winter or early spring, as cold soil and air can prevent seeds from germinating. For recommendations tailored to your specific grass type and climate, consider consulting a local lawn care professional.

Due to its slow growth, Bahia grass does not generally take over weeds. In fact, the opposite can be true. Young Bahia grass is susceptible to being taken over by weeds. 

Likewise, in the cool season, Bahia grass goes into a dormant state that can allow weeds that thrive in early spring to get the upper hand. If you want to prevent weeds from taking over your yard, remove them by hand or apply a Bahia grass-friendly pre-emergent herbicide to your lawn before weeds have a chance to appear.

Planting grass from seed requires time to grow before it can handle even light foot traffic. Most varieties require a minimum of three months before you can walk on them regularly. You can expect to wait at least one year before your lawn can hold up to heavy use. Because sod is already established, it can be walked on more quickly than grass planted from seed.

While hydroseeding is designed for bare soil, it is possible to apply it over an existing lawn with certain adjustments. For the new seed to be successful, it needs good seed-to-soil contact to germinate and take root. Without proper preparation, most of the new seed will fail to establish and will die. To hydroseed over existing grass, first mow the lawn as low as possible, then loosen and clear any exposed soil. It is also recommended to use a finer mulch mixture in the hydroseed spray, which helps the seeds penetrate the existing turf and reach the soil without suffocating the established grass.
