We specialize in the design, installation and maintenance of both custom lawn sprinkler systems and low-voltage LED landscape lighting systems, as well as related products and services.   JMI proudly serves residential, commercial, industrial and municipal clientele throughout Sarnia Lambton, Grand Bend and surrounding area. 

At JMI, we understand that every system we install must be as unique as the landscape it serves. We take the time necessary to develop and implement custom design which will best meet current and projected need. We utilize top-quality components which have proven to meet or exceed our high standards.  We pride ourselves on attention to detail - delivering excellence in workmanship and personalized customer service. In short, we don't believe in cutting corners.  A quality system may cost a bit more initially but will be a far better and more economical investment long term.
