"We had a lot of work completed on our home (read: an expensive job). We had a paver walkway installed. We had some irrigation work (ran downspouts underground to run off points) completed. We expanded gardens that didn't previously have any foundation plantings by adding trees and shrubs, and changed the outdoor lighting. The team was quick to secure and complete the work, but the problem has been the follow up / remediation. The crew chief came out afterwards and noted soil settling where the irrigation work was completed, and that a tree and some shrubs were dying back. He talked about adding soil / seed because the settling was significant (obvious), and replacing plantings (trees / shrubs) that didn't fare well (tree trunk snapped by crew member and has been dying back since). I've contacted the crew chief who made the commitments, particularly since there is a warranty on plantings. Repeated calls and emails have not produced a result. So I strongly recommend avoiding this firm because they do not live to the commitments made."

When we had some issues with the older less reliable lighting programing software, Drew upgraded us at the cost of the new hardware and did not charge us a cent for the labor involved. The new Lutron system has been exceptional and it is helping us both, Envision and my budget, save money since it is rock solid. Envison Outdoor Lighting understands what real customer satisfaction means and I totally, unequivocally, recommend them for ANY installation in Central NJ and Eastern PA !!!.
