I recently had a door installed in my house that was purchased from Lowes. We set up the installation through them, and the contract it out. We had Glen Kerwin from Kerwin Construction come. He did the measurement for the door before it was ordered and then did the installation. He did an amazing job and was super friendly. He answered all my questions and even helped me with a few things not pertaining to the door. He does a lot more than just door installations, and I highly recommend him.
