"This is the worst experience I have had with a landscaping company. Silvio quoted a job at ?$45 per hour, for a couple of hours?, which he admits to saying word for word and agreed to on text. We even said ?so around $90?, which he agreed with. After the job he then charged us for 9 hours, and a $177 dumping fee on top of that. My entire family was at the house, and he was there for 2-3hours. He does not deny this. He then says we have to pay for 9 hours because he decided to bring as many extra men as he chose. He is trying to charge $632 for a job he agreed to do for around $90, this is all confirmed on text. He was physically at the house and walked the property before giving us these quotes face to face as well. So there was no surprise in the job he was doing. Avoid this company at all cost. They must be used to getting away with overcharging people. This man, Silvio, is not trustworthy. "

FAQs for lawn irrigation projects in Riverhead, NY

While watering your lawn by hand might save you money upfront, installing and using a lawn irrigation system does save you money over time. You are less likely to overwater your lawn with a professional irrigation system, which will cause a reduction in water usage. These systems use the right amount of water without waste. In addition, watering your lawn the correct amount will also help prevent different fungi from growing, saving you money in fungi removal costs.

Lawn irrigation is the process of getting water to your lawn, grass and all, for it to grow. There are five main types of lawn irrigation methods:

  • Manual irrigation puts you in charge of the flow of water. Using a sprinkler head on your hose is best to evenly distribute the water across your entire lawn. This doesn’t take much time but requires you to be physically outside holding the hose. 

  • Above-ground sprinklers attach to your hose and rotate or oscillate around your lawn. Since these are above-ground, they’ll need to be moved when it’s time to mow, and depending on the size of your property, you might need to move it around your yard for full coverage. 

  • In-ground sprinklers are flush with the ground when not in use but pop up above the ground level when it's time to water the lawn. Piping for these sprinklers is all found underground, and there are different types of sprinkler heads for different uses and lawn sizes. 

  • Drip irrigation involves drip lines that are more efficient than sprinklers for more extensive lawns. This involves a lot of digging since they are installed underground, but it makes it easy for you to mow.

  • Rainwater collection and irrigation uses nature’s precipitation to water your lawn. This option might not be available in every area since semi-reliable rainfall is needed, though the barrels for this system can range from 15 gallons to 10,000 gallons or more.

Even though having a lawn irrigation system to water your lawn is efficient, you do not want to run it daily. It’s best to run your system two to three times a week. The length of time to run your system varies on factors like wind, temperature, and the variety of your grass, but 10 to 20 minutes each time is generally preferred. If you water too frequently, you’ll drown your grass and plants.

The cost of a lawn sprinkler system is $2,550 for the average homeowner. However, this price can range from $350 to $5,000 or more, depending on the type of sprinkler system you install, the size of your yard, and the type of sprinkler heads you choose. For example, rotating or oscillating sprinkler heads are more expensive than stationary ones, making the cost for one sprinkler head $2.50 to $30 each. Likewise, a yard that is 1/4 of an acre in size averages a total average price of $2,460; however, a one-acre yard averages a cost of $9,840.

The total time it takes to install a lawn irrigation system is roughly one to two days. This includes digging trenches for any necessary underground piping, placing the piping, wiring, sprinkler heads, and valves, and connecting your sprinkler system to your water supply. If you have a lawn larger than one acre, or if there are any municipality regulations that extend the project, you can expect the timeline to be closer to two days.
