Commercial Irrigation Services in New Hampshire

At Alliance Landscaping, we know that a truly thriving commercial landscape isn’t just about green grass—it’s about combining three essential elements:

  • Fertilization – nourishing your turf for strength and resilience.
  • Maintenance – keeping your grounds pristine and professional.
  • Irrigation – delivering water efficiently and consistently where it’s needed most.

Too many businesses focus solely on fertilization and maintenance, overlooking the critical role of a professionally managed irrigation system. The result? Misaligned sprinklers, broken heads, or uneven watering can leave your property looking tired, patchy, or brown, while wasting time, water, and money.

With our commercial irrigation expertise, we ensure every system is precisely calibrated, regularly inspected, and optimized for your property’s unique needs. The outcome: lush, vibrant landscapes that make the right impression on clients, employees, and visitors, year-round, rain or shine.

Invest in irrigation done right. Protect your property, save resources, and showcase a landscape that reflects your business’s standards. Contact Alliance Landscaping today to schedule your commercial irrigation consultation.

Professional Irrigation Maintenance For Optimal Results

At Alliance Landscaping, we know that a properly functioning irrigation system does more than simply water the grass. That's why we offer a comprehensive suite of professional irrigation system services to home and business owners throughout the region. Our watering strategies and solutions ideally complement our 7-Step Lawn Care program, allowing moisture to penetrate through the turf, and strengthening soil and the roots throughout your landscapes for long-term, sustainable results.

Our menu of irrigation services includes:

Spring Start-Up

Alliance Landscaping coordinates your Spring Start-Up appointment with your first fertilization treatment, so your system is ready to go when you need it. Our trained and skilled irrigation technicians' checklist includes:

  • Turn on the main water supply
  • Prime mainline
  • Evaluate zone operation
  • Look for leaks
  • Calibrate pressure for spring conditions
  • Program watering times for spring conditions
  • Align heads for the best coverage
  • Identify necessary repairs
  • Assess controller operation

Fall/Winter Shut Down

Professional winterization of your irrigation system is crucial to its overall lifespan. As the fertilization season draws to a close, Alliance Landscaping's technicians arrive ready to blowout sprinkler heads, lines, rotors, and valves before the temperatures begin to drop. Alliance Landscaping thoroughly winterizes your entire irrigation system to protect it against freeze damage.

Periodic Maintenance Services

Sometimes, even the most well-cared-for irrigation system needs a little extra attention and TLC. Uneven coverage and broken units can (and often do) happen. Not to worry; Alliance Landscaping has got you covered. We specialize in a wide range of irrigation system maintenance and upkeep services throughout the season. If you've noticed that something is off with your watering program, simply give us a call. Alliance Landscaping will perform a comprehensive system evaluation to pinpoint and fix the problem as quickly as possible to keep your watering system running at maximum capacity.

Customized Irrigation Solutions

Most importantly, Alliance Landscaping creates customized irrigation services based on client needs. We carefully evaluate your property to design a watering approach tailor-made for your lawn's soil composition and sun-to-shade ratio. Alliance Landscaping's personalized irrigation services can help transform your property, conserve water, and even lower your utility bills.
