Irrigation Service & Repair in Colorado
Comprehensive irrigation diagnostics, repair, and system upgrades for commercial and residential properties across Douglas County and the Denver Metro area. JLS has been solving sprinkler problems since 1975.
Why Irrigation Repair Matters in Colorado
Colorado's semi-arid climate delivers only 15 to 17 inches of annual precipitation along the Front Range -- less than half of what most turf grasses need to survive. That makes your irrigation system the single most important piece of infrastructure keeping your landscape alive.
When a sprinkler system malfunctions in Colorado, the consequences show up fast. A broken head can waste hundreds of gallons per cycle while leaving adjacent zones bone dry. A stuck valve can flood one area and starve another. A cracked mainline buried under a parking lot can spike your water bill by thousands of dollars before anyone notices. And in Douglas County, where water districts like Castle Rock Water and Parker Water & Sanitation enforce tiered pricing structures, inefficient irrigation doesn't just kill your landscape -- it kills your budget.
JLS Landscape & Sprinkler has been installing and repairing irrigation systems along the Colorado Front Range since 1975. Our technicians diagnose problems zone by zone, identify the root cause rather than just the symptom, and repair systems to operate efficiently within local water restrictions. Whether you manage a 50-acre HOA common area or a single commercial building, we bring the same systematic approach to every service call.
Spring 2026 advisory: Colorado's ongoing drought conditions and above-average spring temperatures mean irrigation systems are activating earlier than typical years. If your system wasn't properly winterized last fall, freeze damage may not become apparent until the first full pressurization. Schedule a spring diagnostic before damage compounds. Call 303-791-9121 to book your inspection.
Irrigation Repair Services
From a single broken head to a complete system overhaul, JLS handles every component of commercial and residential irrigation systems.
Head Replacement & Adjustment
Broken, tilted, or sunken sprinkler heads waste water and create dry spots. We replace damaged heads, adjust spray patterns, and ensure proper nozzle selection for each zone's specific coverage needs.
Valve Diagnostics & Repair
Solenoid failures, diaphragm tears, and wiring faults are the most common valve problems in Colorado. We test each valve electrically and hydraulically, replacing only the components that have actually failed.
Line & Mainline Repair
Freeze damage, root intrusion, and soil settlement crack lateral lines and mainlines. We locate breaks using pressure testing and visual inspection, then repair or reroute lines with minimal excavation and landscape disruption.
Controller Programming
Outdated or incorrectly programmed controllers waste enormous amounts of water. We reprogram existing controllers for optimal scheduling or upgrade to EPA WaterSense-certified smart controllers that adjust automatically based on weather conditions.
Backflow Preventer Service
Colorado requires annual backflow testing on all irrigation systems connected to municipal water. We test, repair, and certify RPZ and PVB backflow devices to keep your system in compliance with state and local codes.
System Audits & Efficiency
A full irrigation audit measures precipitation rates, identifies coverage gaps, checks pressure uniformity, and calculates water waste. For large commercial properties, audits regularly identify 20-40% savings opportunities through targeted repairs and scheduling adjustments.
Irrigation Problems Unique to the Front Range
Colorado's climate creates irrigation challenges that don't exist in most other states. Understanding these local factors is the difference between a repair that lasts and one that fails again next season.
- Freeze-thaw cycling: Colorado can swing 50 degrees in a single day. Pipes that freeze at night and thaw by noon create stress fractures that worsen over multiple cycles before failing completely
- Expansive clay soils: Douglas County's heavy clay expands when wet and contracts when dry, shifting pipe alignments and shearing fittings. Systems need flexible joints at transition points
- High UV degradation: At 6,000+ feet, UV intensity is 25% stronger than at sea level. Exposed components degrade faster, and above-grade poly pipe becomes brittle within a few seasons
- Low humidity: Colorado's 30-40% average humidity means evaporation rates are dramatically higher than national averages. Systems must compensate with proper scheduling and matched precipitation rates
- Water restrictions: Watering windows, day-of-week rules, and tiered pricing from Castle Rock Water, Parker Water, and Denver Water all affect how your system should be programmed

Learn MoreIrrigation Service FAQ
Common signs include dry spots or brown patches despite regular watering, unusually high water bills, soggy areas or standing water near sprinkler heads, heads that don't pop up or rotate properly, and visible leaks at valve boxes. Colorado's freeze-thaw cycles cause more irrigation damage than most climates -- schedule a diagnostic if your system is over five years old or wasn't properly winterized last fall.
Costs vary based on the issue. A simple head replacement is significantly less than a mainline repair or valve replacement. JLS provides upfront diagnostics so you know exactly what's wrong before authorizing any work. Call 303-791-9121 for a service appointment.
Yes. We install EPA WaterSense-certified smart controllers that adjust watering schedules based on real-time weather data, soil moisture, and plant type. In Douglas County where water is expensive and restricted, smart controllers typically reduce outdoor water use by 20-40% while keeping landscapes healthier than manual timers.
We perform winterization blowouts in the fall and emergency repairs year-round. In Colorado, winter watering is sometimes necessary for trees and shrubs during dry, snowless periods -- we can set up winter watering schedules and ensure your system handles the freeze-thaw cycle safely.
