CUSTOMER TESTIMONIALS

"From our first call and meeting at the property site, James was helpful, informative and professional. I wish I hadn’t bothered to get other quotes. No need. James and Andres were fantastic! So easy to work with. Had the perfect subs lined up for things like electrical. The contract was clear to read, and again – professional in its scope. James and Andrew kept me informed during all phases of the projects, responded to all questions, and were always so pleasant. I like people who are kind, honest and know their job. Not always easy to find. James & Active Underground are GREAT!!! Not 5 stars – 10 STARS!!!"

"James was very responsive in getting back to me and making quick arrangements to do repair. The crew was on time, informative, professional and did a very good job in both completing the necessary repair and returning site to original condition. Two individuals had recommended Active Underground to me and I would certainly recommend to others"
