“One of the best additions to our home has been a four season sunroom built by Bear Builders. This has added elegance and beauty and is used almost daily. I have never worked with any company or contractor as responsive and as customer service oriented as this one. A company where you get to talk to the owner right away. When they say you have a lifetime guarantee they mean it. We have had our sunroom now for more than three years and even now if I have a problem I call Scott and get an immediate response. Truly a marvelous company and I cannot recommend it enough.”
