Konstantin did a superb job installing my door. He did something that installers from a professional door company could not do. He replaced a custom door that has a transom with a standard pre hung door. Not only that the quality of his work is top notch. In addition, he helped me select the door. He came late in the afternoon. But darkness did not stop him. He came prepared to work in the dark. And he did a good job cleaning up.

Constantin suggested three variants how to improve the entry door look and feel, with itemized pricing. We were able to discuss and choose a variant, which was best for us. No pressure, no rush, great communication. We got nicely looking and functioning entry door plus a storm door, thank you!
