Jay Kay Testing Inc. was established in 1994 with faith in God and one client. In 2018, we are celebrating our 24th year in business. We have provided independent soils laboratory services to more than sixty firms over the years. We believe that ultimately we have to answer to the Lord for our service. As a result, we focus on accuracy, quality control and attention to detail. We strive to be a light in the industry and provide our clients with the highest quality of service while maintaining integrity and honoring God. We believe Christ works through us and provides to us completely. Thus we ultimately have to answer to him for our work.
