O’Keefe Landscape & Irrigation | Local Landscapers in Merrimack, NH

Absolutely. Bare patches are common here due to soil compaction, wear, or seasonal stress. Our landscape maintenance team addresses this through core aeration to relieve compaction, followed by overseeding with hardy grass blends suited for our New Hampshire climate. The ideal times for this service are early fall or spring, when temperatures are cooler and moisture is more consistent, giving new grass the best chance to establish strong roots before summer heat or winter frost.

Timer or controller failure is a frequent issue we see in Merrimack. During an irrigation repair visit, our technicians will first diagnose the controller itself—checking for power issues, faulty wiring, or programming errors. We then inspect the connected valves and wiring in the field for damage. Often, the problem is a simple programming reset or a single valve issue. We'll fix the immediate problem, ensure all zones are running efficiently to prevent water waste, and can discuss upgrading to a smart, weather-based controller for even better water conservation.

Our landscape design process for Merrimack homeowners always considers our four-season climate. We select native and hardy plants that thrive here with less water and care. For hardscaping and layout, we strategically plan for snow removal, ensuring clear paths for plows and avoiding features that trap snow or ice. We can also integrate your new irrigation system directly into the design for optimal coverage and efficiency. The goal is a beautiful, cohesive outdoor space that's built to look great year-round and is easy for you to manage, with us handling the seasonal maintenance and snow removal.
