Client Testimonials

"Greenwood was selected to provide roof repairs and replacements on four (4) projects for various public facility owners in Massachusetts. Throughout these projects, Greenwood lived up to their claims and our expectations. Staff members, during all phases of these projects, displayed well versed technical skills and professionalism. When potential concerns did occur, your staff addressed these issues in a timely manner. Therefore, we do not hesitate to recommend Greenwood Industries and look forward to working on future projects together."
