​In 1975, JLS opened as an irrigation installation and repair company.  The focus of the company has changed a few times, always responding to variations in the market and economy while staying true to company values.  In 1999, JLS began to phase out the residential sector of the business in order to focus on what they do best.  This transition took about 18 months.  Since then, JLS has streamlined its services, now servicing exclusively commercial and shopping center clients.  In the early 2000s, JLS  continued to improve and made a concerted effort to grow the snow removal side in an effort to maintain revenue and retain staff through the winter months.  Currently, the "white side" of the business generates 60% of the annual volume.
​We've met our goal of employing more year-round than seasonal employees.
