Thank you so much Konstantin! He’s done a wonderful job securing 2 of my doors with many issues from the door frame to the alignment of my storm doors, he’s saved me from buying brand new doors. They are opening and closing like a charm, finally! What a relief. He’ll be back to secure my front door and add a new storm door shortly, I don’t have to search for the replacement items myself either, he gave great suggestions and made it easy for me. Thanks again!
