Irrigation System Maintenance

A healthy commercial landscape depends on getting the right amount of water to the right places at the right time. Along Colorado’s Front Range, changing temperatures, dry conditions and seasonal weather make proactive irrigation management especially important.

Keesen Landscape provides commercial irrigation system maintenance in Denver, Colorado Springs and surrounding Front Range communities. We help property managers, HOAs, developers and commercial property owners maintain reliable irrigation systems through seasonal start-ups, routine inspections, controller adjustments, repairs and winterization.

Our approach goes beyond turning the system on and off. We continually monitor irrigation performance and adjust watering based on your landscape and changing conditions.

Commercial Irrigation Maintenance Throughout the Season

Irrigation needs change throughout Colorado’s growing season. A watering schedule that works in spring may not be appropriate during the heat of summer or as temperatures cool in fall.

Keesen incorporates irrigation monitoring into the ongoing management of your landscape. Our teams inspect system performance, identify potential issues and make seasonal adjustments designed to maintain appropriate soil moisture and coverage.

That proactive approach helps support plant health while making more thoughtful use of water.

Our Commercial Irrigation Services

Irrigation System Start-Up

Colorado winters can be hard on irrigation systems. During spring start-up, Keesen restores water flow and inspects the system for proper operation.

Our team checks water flow and pressure, looks for valve and line leaks, identifies broken sprinkler heads and makes adjustments for appropriate coverage. We also program the irrigation controller to prepare the system for the growing season.

Irrigation Inspections

Regular inspections help us identify irrigation issues before they have a larger impact on your landscape.

Keesen schedules irrigation service visits according to the needs of the property. During these checks, we inspect zones for proper water flow and pressure, monitor for leaks, identify needed repairs and adjust sprinkler heads for appropriate coverage.

Irrigation Controller Adjustments

Commercial landscapes don't need the same amount of water all season.

Keesen periodically adjusts watering intervals and zone run times based on environmental conditions and the needs of the landscape. These adjustments help maintain appropriate soil moisture as conditions change.

Irrigation System Repairs

Leaks, damaged heads and worn irrigation components can affect both water use and landscape health.

During irrigation checks and other property inspections, Keesen continually monitors the system for potential problems. When repairs are needed, we'll communicate the issue and any costs that fall outside the existing service agreement before completing necessary repairs.

Irrigation Winterization

Freezing temperatures make proper irrigation winterization particularly important in Colorado.

At the end of the watering season, Keesen prepares irrigation lines for winter by clearing them with compressed air and shutting off the controller and water source.

Our annual landscape calendar also accounts for irrigation winterization and backflow wrapping as temperatures begin to change.

Backflow Testing

Backflow testing is available as part of Keesen's irrigation services. Our maintenance calendar includes backflow testing as a seasonal irrigation service, while the landscape management program notes that backflow inspections are available upon request.

Irrigation Management That Supports the Entire Landscape

An irrigation system isn't just infrastructure. Its performance directly affects the turf, trees, shrubs, flowers and other plant material throughout your property.

That's why Keesen manages irrigation as part of a broader commercial landscape program.

By looking at both the irrigation system and the landscape it supports, our team can identify concerns such as improper coverage, leaks or changing watering needs and recommend appropriate adjustments.

The result is a more connected approach to irrigation—focused on supporting both reliable system performance and long-term landscape health.

Irrigation Maintenance for Colorado’s Changing Conditions

Colorado weather rarely follows a fixed schedule, and irrigation shouldn't either.

Keesen's landscape maintenance calendar specifically notes that service schedules can vary from year to year depending on weather conditions. Irrigation activation, ongoing system checks and winterization are planned around the seasonal needs of the property rather than treated as isolated services.

That flexibility is particularly important along the Front Range, where landscape conditions can change significantly throughout the growing season.

Frequently Asked Questions About Commercial Irrigation

What does commercial irrigation maintenance include?

Commercial irrigation maintenance can include seasonal start-up, system inspections, controller adjustments, leak detection, sprinkler head adjustments, repairs and winterization. Keesen builds irrigation service around the needs of each commercial property and its landscape.

How often should a commercial irrigation system be inspected?

Inspection frequency depends on the property and its landscape needs. Keesen schedules irrigation service visits throughout the growing season and checks zones for water flow, pressure, leaks, needed repairs and sprinkler coverage.

Why do irrigation controllers need seasonal adjustments?

Landscape water needs change as weather and environmental conditions change. Adjusting watering intervals and zone durations helps maintain appropriate soil moisture rather than relying on the same watering schedule throughout the growing season.

When should irrigation systems be winterized in Colorado?

Winterization should occur as the watering season ends and before freezing conditions can damage the system. Exact timing can vary with Colorado weather, which is why Keesen's seasonal maintenance schedule is adjusted as conditions dictate.

Can Keesen repair problems found during an irrigation inspection?

Yes. Keesen monitors irrigation systems during scheduled checks and other inspections. If a repair is needed, the team communicates costs outside the existing service agreement and can make the necessary repairs.

Keep Your Irrigation System—and Landscape—Performing

Reliable irrigation requires attention throughout the season. From spring start-up through winterization, Keesen helps commercial properties adapt their irrigation systems to changing landscape needs and Colorado conditions.
