About JLS Landscape & Sprinkler
Since 1975, JLS Landscape & Sprinkler has been the trusted partner for commercial landscape maintenance and snow removal across Denver Metro and Douglas County. Our mission is simple: People, Service, Quality, Continuous Improvement.
50+ Years of Colorado Landscape Excellence
Founded by their father and grandfather as a residential landscape and irrigation company, JLS was built on hands-on service, strong client relationships, and pride in the communities it serves. Over the past decade, the company focused exclusively on commercial landscape maintenance, irrigation, and snow management, becoming one of the region's most trusted year-round service providers. Today, under John and Jeremy's leadership, JLS is expanding back into residential services in the very communities where they live and work—bringing the company full circle while honoring its roots.
Founded as an Irrigation Company
JLS Landscape & Sprinkler was founded in Sedalia, Colorado, specializing in sprinkler system installation and repair for residential and commercial properties across the Denver Metro area. From day one, the company built its reputation on technical expertise and reliable service.
Expanded into Full-Service Landscaping
As demand grew, JLS expanded beyond irrigation into comprehensive landscape maintenance, hardscape installation, and seasonal grounds care. The company developed long-term relationships with commercial property managers, HOAs, and metro districts throughout Douglas County and the greater Denver area.
Transitioned to Exclusively Commercial
JLS made the strategic decision to phase out residential services and focus exclusively on commercial accounts. This shift allowed the company to invest in heavy equipment, specialized training, and the operational infrastructure needed to serve large-scale properties with consistent, professional-grade results.
Built a Snow Removal Powerhouse
JLS grew its snow and ice management division into the primary revenue driver, accounting for 60% of annual revenue. The company assembled a fleet of wheel loaders, skid steers, pickup plows, and de-icing equipment. Staff earned CSP (Certified Snow Professional) credentials, and the team was featured on the cover of SNOW BUSINESS magazine for their industry-leading operations.
Sustainable Practices & Residential Expansion
JLS deepened its commitment to water conservation and sustainable landscape practices, earning QWEL certification for water-efficient landscaping. The company also began expanding back into residential services across Douglas County — including Castle Rock, Highlands Ranch, Larkspur, Parker, Lone Tree, and Castle Pines — bringing 50+ years of commercial-grade expertise to homeowners in the communities where John and Jeremy live and work.
Meet the Team Behind JLS
JLS is led by John W Reffel IV and Jeremy Reffel, who together bring decades of hands-on experience in landscape management, snow operations, and business leadership.
