GRE were the electrical contractor on our house build in Mapua. Their input was one of the highlights of the build process. They provided great input on the design of all of the electrical systems covering lighting, PV, automation and general power and showed patience while we figured out our final requirements with other contractors. On the job they were courteous, on time, kept us informed, and did what they said they would do. We love the outcome and would recommend the GRE team to others.
