Irrigation Installation & Seasonal Servicing
A properly designed irrigation system takes the guesswork out of watering and helps protect your landscape investment. Our Irrigation Installation and Seasonal Servicing solutions are designed to keep your plants healthy while maximizing efficiency and compliance with local watering requirements.
​
At Agassiz Landscape Group, we handle everything from new irrigation system installations to seasonal maintenance—so you don’t have to worry about timing, weather, or system failures.
Irrigation System Installation
Installing a timer-controlled irrigation system helps ensure your landscape receives the right amount of water at the right time. We design and install irrigation systems tailored to your property’s layout, plant types, and water needs.
A properly installed system can:
-
Reduce water waste
-
Improve plant health
-
Save time and effort
-
Protect your landscape investment
Our team focuses on efficiency, functionality, and long-term performance when installing irrigation systems for residential and commercial properties.
Fall Irrigation Winterization
Living in Flagstaff, irrigation systems must be properly shut down before winter. With an average of 100 inches of snow each year and frequent below-freezing temperatures, failing to winterize your system can lead to frozen and broken lines, valves, and sprinkler heads.
We provide professional irrigation winterization (blow-outs) to safely remove water from your system, helping prevent costly damage and repairs. This seasonal service is critical to protecting your landscape investment through the winter months.
Spring Start-Up & System Check
When warmer weather returns, we offer spring irrigation start-up services to get your system running smoothly again. During spring activation, we:
-
Re-pressurize the system
-
Inspect valves, lines, and connections
-
Check and replace broken sprinkler heads or emitters
-
Test coverage and adjust as needed
Snow, ice, and shifting ground can cause damage over winter—our thorough checks help catch issues early before they become bigger problems.
Watering Compliance & Smart Scheduling
The City of Flagstaff has watering restrictions, and knowing when and how long to water can be confusing. Our team stays informed on local regulations and will program your irrigation controller to remain compliant—while still keeping your plants healthy and thriving.
Automatic Seasonal Service Option
We know you’re busy. For clients who don’t want to remember when to schedule seasonal irrigation services, we offer an automatic repeat service option.
With this option:
-
We monitor weather and temperatures for you
-
We schedule winterization and spring start-ups at the right time
-
We service systems neighborhood by neighborhood for efficiency
No reminders, no stress—just peace of mind knowing your irrigation system is handled properly each season.
