MG McGrath is a Certified Environmentally Responsible Contractor! This certification recognizes MG McGrath as a contractor who properly understands, trains employees, and acts to mitigate the environmental risks in our business practices. Environmental risks have historically gone overlooked and unaddressed until an incident happens, but not at MG McGrath. Our CERC certification gives peace of mind to contractors, owners, insurance providers, and government agencies to show that we are taking active steps to prevent incidents and be environmentally responsible in our construction work.
