I reached out to Marc to get an estimate for new windows in our house to stop the cold draft coming in. He scheduled promptly and came today. He did something so refreshing and kind as he said we actually do not need new windows just to have new caulking around them. He said he did not want me to waste the money. I would work with Marc on any future projects and recommend him if you are looking for someone who is honest and fair in addition to being highly recommended through reviews on the quality of his work.
