Common Questions

What's the most common cause of dead grass patches in Forest Knolls, and how do you fix it?

In our area, dead patches are often a symptom of underlying irrigation issues, like clogged heads, low pressure, or leaks in the lines. We start with a thorough inspection of your entire system, checking for breaks and ensuring even coverage. The fix usually involves repairing the leak, adjusting or replacing sprinkler heads, and sometimes aerating the soil to improve water penetration. For chronically problematic areas, we might recommend switching to a more efficient drip line or exploring water-wise ground covers suited to our local climate.

How can I tell if I have an irrigation leak, and what should I do?

Signs include a sudden spike in your water bill, soggy spots or moss growth in dry areas, and low pressure at your sprinkler heads. The first step is to check your water meter before and after a two-hour period when no water is being used; if it moves, you likely have a leak. Don't ignore it—even a small leak can waste thousands of gallons. Give us a call. We'll perform a pressure test and use specialized equipment to locate the leak precisely, whether it's at a valve, a connection, or a cracked pipe, and make a targeted repair to save water and protect your landscape.

My lawn has several brown areas even with regular watering. Can you help?

Absolutely. This is a frequent issue here, often due to uneven water distribution from an outdated or poorly calibrated irrigation system. We'll perform an audit, running each zone to measure coverage and identify dry spots. The solution may involve reconfiguring sprinkler head placement, adjusting spray patterns, or retrofitting zones with more efficient nozzles. In some cases, the soil in those spots may be compacted or hydrophobic (repels water), requiring aeration and wetting agents. Our goal is to ensure every part of your landscape gets the water it needs—no more, no less—to stay healthy and green.
