"We are very happy with the results and would like to give 4.5 stars if we could. They're a great company to work with and the job was fairly priced and done well. We would definitely work with CVB again. In addition to the kitchen remodel, they also did work on another house project and we were thoroughly satisfied. Our only suggestion is for the crew to be better prepared when getting to the job site. Additional time was spent collecting/buying tools and material after arriving."

"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."

Fire Sprinkler Companies questions, answered by experts

Installing an aboveground sprinkler system takes about two to four hours, depending on the size and setup. Most projects will not take longer than a day to complete, but installing an underground system will take eight to 16 labor hours. For a better idea of what to expect, ask your contractor about the expected timeline when they’re creating your estimate.

You can find irrigation lines whether you dig or not. If you decide to dig, do so near valve boxes and around sprinkler heads. Once you find the first pipe, you can map the system from there and use spray paint or tape to mark the pipe layout throughout.  

If you don’t feel like digging, aside from getting a map from the maker of the irrigation system, you can still find irrigation lines by locating the valve box and following a line back to the head sprinklers. You can also use a water-detection device or a metal detector, which will work if the lines have metal tracer wires.

It depends on the system. Some drip irrigation systems, like emitter and misting systems, need to have their nozzles exposed. Drip tape and soaker hoses can be covered with a light layer of mulch to avoid damage from foot traffic, garden tools, and UV rays. However, ensure the tape or hose is designed to be buried and inspect it regularly for any signs of damage or mold growth.

Sprinkler valves typically have 16 AWG or 18 AWG wires. AWG, or American Wire Gauge, is the standard measurement for wire gauge sizing in the U.S. The gauge is the thickness of the wire, with higher AWG numbers indicating thinner wires. You can find the gauge measurement in your sprinkler system’s user manual or on the sprinkler manufacturer’s website.

In most cases, you don’t need to water a garden every day. Water plants in well-draining sandy soil about twice a week, and water plants in mulch or heavier clay soils about once per week. If temperatures are extremely hot, you may need to water every day. A good rule of thumb is to stick your finger in the soil. If it’s dry a few inches down, your plants could use water.
