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.

Details: Exterior door, like a front or patio door • 1 door • Standard • Mixed materials, like wood with windows • Yes, the new door replaces an existing door • No, I need professional’s help in purchasing • Install locks or hardware • Install new trim around the door • Home

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!

Constantin did such a great job replacing our patio door. We had countless people come to our house to “fix” our door and finally I decided to replace it. Constantin picked up our new door and disposed of the old one and got it installed in record time. Working with him was so easy I will absolutely call him again for all window and door projects in the future. I cannot say enough good things about how great he was to work with!
