We have been in the construction industry for over 10 years. From building ADUs, high-end kitchen remodels, bathroom remodels and home extensions, we have done just about everything under general construction. Our company prioritizes safety, quality and transparency.

"Me and my wife decided recently to get our kitchen remolded. After some time searching for the right guys to do the job we settled on RG Construction. Richard, who is the owner, is a great guy and super informative. He never left any question unanswered or left us uncertain about anything. His crew works quick, and they pay attention to the tiniest detail. They absolutely are worth every dollar and I would recommend RG Construction to any homeowner, and I for sure will be giving them a call back for any work I need done in the future. Me and my wife are absolutely in love with our remodel."

"Tony and his crew were skilled, professional and did a wonderful job. When I listed the job on Angi, Tony responded within 20 minutes. He asked about the job, asked for some pictures and I had a solid quote within an hour. Our installation had some challenges and, instead of making these issues more complicated and jacking up the price like other contractors did, he quickly came up with sensible solutions at a fair price. The job was done in one day and our new tankless water heater is superb! I highly recommend Tony and Tankless Plumbing Solutions."

Fire Sprinkler Companies questions, answered by experts

Sprinkler systems are usually worth the investment, not only because they appeal to buyers when you sell your home but also because they help keep your lawn looking beautiful, which can increase curb appeal. In fact, you can expect a return on investment for a sprinkler system to sit between 80% and 90%, making it a better home improvement project than most in terms of value. It’s crucial to hire a sprinkler system professional for installation to ensure maximum value, as that will confirm for buyers that the system will likely last for years without issues.

For many homes, sprinkler rain sensors are worth it. Since the sensor stops your sprinklers from running when it’s raining, it’ll help you save water and, in turn, reduce your water bills. As a result, your rain sensor could easily pay for itself over its lifetime. Rain sensors also help prevent overwatering, a common lawn irrigation mistake that can damage your grass.

While specifics depend on a lot of factors, the average sprinkler controller can last between five and 10 years—which, critically, is a shorter life span than the average sprinkler valve boasts (between 10 and 15 years). That means chances are good you’ll need to replace your irrigation controller at some point during your sprinkler’s lifetime.

Many sprinkler heads have a small screw on top, often called a radius adjustment screw, that is designed to adjust the length of the stream coming from the nozzle. Insert a screwdriver or hex key that fits the screw opening and twist it clockwise to lengthen how far the stream sprays, or twist it counterclockwise to shorten the stream length.

The number of heads in a sprinkler system varies based on the size of the property and the layout, but the typical system consists of ten sprinkler heads split into two or three zones. Larger properties will naturally require more sprinkler heads, and smaller properties might require fewer. If you have an abnormally shaped property or obstructions—like trees, fences, and retaining walls—you might need additional heads to ensure your entire property is irrigated. The best way to determine how many heads you need is to have a professional assess your home and draw up an estimate.
