My wife and I had no idea we had mold in our attic. It was only when we asked a company to quote on insulation that we learned we had a problem. I found The Concord Group on-line and, when I phoned the company, the owner made me feel comfortable. Our mold problem became his priority and he assured me that his team had the knowledge and equipment to remove all the mold in our attic. The two employees arrived in the early morning. They were cheerful and got right down to the business of mold removal. By showing us before and after photos my wife and I are confident we no longer have mold in our attic. I recommend The Concord Group most highly and give them 10 stars!
