JMJ Construction Specializes in the Commercial Playground Industry. We cater to public entities such as schools, municipalities, churches, and daycares. Our experience in this field has surpassed 15 years. We are fully insured and our capability to bond jobs has given us the opportunity to build many public parks throughout the state of California. In 2010 we opened up a residential division that specializes in selling and installing Alumawood Patios. This division has grown so fast and the quality of the Alumawood product has made this expansion a successful enterprise.
