Frequently Asked Questions
What's the most common cause of patchy grass in Sag Harbor, and how do you fix it?
In Sag Harbor, patchy lawns are often due to a combination of compacted soil, improper watering from leaky or misaligned sprinklers, and seasonal stress. Our fix starts with a thorough inspection of your irrigation system for leaks and coverage gaps. We then perform core aeration to relieve soil compaction and overseed with high-quality grass blends suited to our local climate. Finally, we adjust your watering schedule for deep, infrequent watering that promotes strong root growth and a lush, even lawn.
My water bill is high, and I suspect a sprinkler leak. Can you help?
Absolutely. A sudden spike in your water bill is a classic sign of a sprinkler system leak, which is very common here. Our technicians perform a detailed pressure test and inspection of all zones, valves, and sprinkler heads. We quickly locate the source—whether it's a cracked pipe, a faulty valve, or a damaged head—and make precise repairs. We also check for overspray onto driveways and sidewalks to ensure every drop of water is used efficiently on your lawn, saving you money and conserving water.
Do you offer a maintenance plan to prevent these common lawn problems?
Yes, we offer tailored seasonal maintenance plans designed specifically for Sag Harbor properties. Our proactive approach includes regular sprinkler system checks and adjustments, seasonal fertilization and weed control, aeration, and overseeding as needed. This consistent care prevents small issues like minor leaks or thin spots from turning into larger, more expensive problems, ensuring your lawn stays healthy and vibrant year-round with minimal hassle for you.
