On Friday, the crews of Three Sons Window and Door, Inc. went to the classroom instead of the job site. We are happy to say that all of our crews are safety certified. We are committed to our customers to practice safe and responsible practices while working on every job no matter what the size. We are also a lead safe company. Don’t be fooled by companies that charge extra for appropriate lead safe practices. At Three Sons Window and Door, we do it every time. Call us today at 781-899-6353. We are A+ rated by the BBB as well as with Angie’s List.
