Landscape Maintenance Questions
JLS services a wide range of commercial and residential properties. On the commercial side, we maintain LEED-certified buildings, shopping centers, office parks, healthcare facilities, metro district common areas, industrial sites, and warehouses. We are also expanding our residential services in Douglas County, serving homeowners in Castle Rock, Highlands Ranch, Parker, Lone Tree, Castle Pines, Littleton, Sedalia, Conifer, Larkspur, and Monument. Our client roster includes high-profile venues like Coors Field.
JLS Landscape & Sprinkler was founded in 1975, giving us over 50 years of experience maintaining Colorado properties. We started as an irrigation company, grew into full-service landscaping, transitioned to exclusively commercial work in 1999, and are now expanding back into residential services in Douglas County. Our longevity reflects the trust our clients place in our team and the consistency of our results.
Yes. After focusing exclusively on commercial accounts since 2001, JLS is expanding back into residential landscape services in Douglas County. We offer residential landscape maintenance, irrigation management, sprinkler repair, lawn aeration, sprinkler blowout, and fire mitigation for homeowners. Residential clients benefit from the same professional-grade equipment, certified technicians, and year-round crews that maintain Denver's largest commercial properties.
JLS staff hold multiple industry certifications: Certified Snow Professional (CSP) through SIMA, Licensed Irrigation Contractor Technician (LICT), LEED Accredited Professional (LEED AP) through the U.S. Green Building Council, and Pesticide Qualified Supervisor credentials through the Colorado Department of Agriculture. We are active members of ALCC, BOMA, CALCP, SIMA, RMSCA, IFMA, USGBC, and local chambers of commerce in Castle Pines, Castle Rock, and Larkspur.
Yes. JLS has LEED AP (Accredited Professional) staff members who understand the specific landscape requirements for LEED-certified buildings. This includes water-efficient irrigation design, native and drought-tolerant plant selection, reduced chemical usage, and documentation needed for ongoing LEED compliance. We help property managers maintain their green building certifications while keeping landscapes attractive and functional.
Snow Removal Questions
JLS monitors weather conditions 24/7 during storm season using multiple forecasting services. Before a storm arrives, we pre-treat surfaces with salt brine to prevent ice bonding. During the event, our CSP-certified crews deploy a fleet of wheel loaders, skid steers, pickup plows, and de-icing units to clear parking lots, sidewalks, and access points. Our year-round employment model means the same trained professionals who know your property in summer are the ones clearing it in winter. We offer both per-push and seasonal contract options.
Zero-tolerance snow removal means that any measurable accumulation of snow or ice is addressed immediately, regardless of the time of day or night. This service level is required for high-traffic properties like healthcare facilities, emergency entrances, retail centers, and corporate campuses where slip-and-fall liability is a primary concern. JLS provides zero-tolerance service with continuous monitoring, pre-treatment, and immediate deployment at the first sign of accumulation. It is our most comprehensive snow management offering.
JLS operates a diverse fleet of snow removal equipment sized for properties ranging from small sidewalks to large commercial parking lots. Our inventory includes Caterpillar wheel loaders, skid steer loaders with snow pushers, pickup trucks with plow attachments, liquid brine applicators for pre-treatment, granular salt spreaders, and walk-behind equipment for sidewalks and building entrances. Snow and ice management generates 60% of our annual revenue, which means we invest heavily in equipment maintenance, operator training, and fleet readiness.
Irrigation & Sprinkler Questions
Schedule your sprinkler blowout between early October and mid-November in the Denver Metro area. Colorado's first hard freeze typically arrives in late October, and water left in irrigation lines can freeze, expand, and crack pipes, fittings, and valves. JLS recommends booking by mid-September to secure your preferred date, as demand peaks in October. We use industrial-grade air compressors to fully clear every zone. One missed season can result in thousands of dollars in spring repair costs.
JLS has saved hundreds of thousands of gallons of water through smart irrigation upgrades. Our approach includes weather-based controllers that adjust watering schedules automatically based on real-time temperature, rainfall, and evapotranspiration data. We also convert traditional spray zones to drip irrigation where appropriate, optimize zone layouts to eliminate overspray and runoff, and recommend drought-tolerant plant species for new installations. Our LEED AP staff bring green building water management expertise to every commercial property we maintain.
Yes. Our LICT-certified technicians service all major sprinkler system brands including Rain Bird, Hunter, Toro, Irritrol, Weathermatic, and K-Rain. We carry common replacement parts on every service truck so most repairs are completed in a single visit. Whether you need a broken sprinkler head replaced, a leaking valve repaired, a controller reprogrammed, or a damaged main line fixed, JLS has the parts and expertise to handle it efficiently.

Several factors set JLS apart. First, our 50+ year track record and client relationships with marquee properties like Coors Field demonstrate proven reliability. Second, our year-round employment model means you get the same trained, experienced crew members in every season, not seasonal day laborers. Third, our certifications (CSP, LICT, LEED AP, Pesticide QS) reflect genuine expertise, not just surface-level credentials. Fourth, we are investing in the future with 10 Scythe Robotics autonomous mowers and water-saving irrigation technology. Finally, our deep community roots, including 20+ years volunteering at Mt. Saint Vincent Home, reflect the integrity that guides everything we do.
Yes. JLS provides year-round property care. In spring and summer, we handle landscape maintenance, irrigation startups, seasonal color rotations, and lawn aeration. In fall, we manage leaf removal, sprinkler blowout, and pre-season snow preparation. In winter, our CSP-certified snow crews provide 24/7 snow and ice management. We offer bundled annual contracts that combine landscape and snow services at a predictable monthly rate, ensuring continuous care and a single point of contact for all your property needs.
Fire mitigation is the process of creating defensible space around structures to reduce the risk of wildfire damage. In Colorado, this involves removing dead trees and brush, thinning dense vegetation, eliminating ground fuels like dead leaves and pine needles, and establishing fuel breaks between natural vegetation and buildings. JLS provides fire mitigation services for properties in wildfire-prone areas of Douglas County, including Conifer, Larkspur, Monument, Castle Pines, and Sedalia. Many Colorado counties offer fire mitigation cost-sharing programs for homeowners.
JLS is frequently hiring for positions including Crew Team Members and Crew Leads. We offer year-round employment (not seasonal), competitive pay, growth opportunities, and the chance to work with a team that has been serving Colorado for over 50 years.
