Constantin was very diligent and I am quite happy with the look of the new doors he installed and how well they addressed the issue we had with air draft. Would recommend!!!

Constantin did an outstanding job replacing old entry doors and a storm door installation for us. He was very responsive and easy to communicate with throughout the process. His work was top-notch—everything looks fantastic, and the quality of his craftsmanship really shows in the details, especially with the wood casing. We’re extremely happy with the results and wouldn’t hesitate to recommend him to anyone looking for reliable, professional work.

Constantin is very hardworking and did a great job installing a double french door and a single pre-hung door, including the drywall extension work that was needed. It looked exactly as expected. The extended drywall joint looks slightly bumpy, and the edges a are visible, but I gave him 5 stars because he is a door installer expert. He suggested hiring a painter to do a few layers of spackling, which I skipped for now. Here are some before, in-progress and after pictures. The final pictures are after I painted the drywall and the doors.

Working with Constantin was a pleasure. He measured the glass door that I wanted to replace, and filled out the proper glass forms for this custom order. Once the order was delivered he came back to my home and did the install. The pricing was fair, the quality of his work was exceptional. I would definitely recommend him if you need any window/glass work installed or repaired. Thank you Constantine!

Working with Constantin was great! He was very responsive from the beginning, answered all our questions, and offered his expertise along the way. The first door we ordered from the store for delivery was damaged and we didn’t have a big enough car to pick up another so there was going to be a delay with the next delivery. Constantin offered to pick up a replacement door for us - truly going above and beyond. The work was immaculate, he changed the exterior frame and door for us, added inside trim, and installed our hardware. I would definitely recommend him to others looking to get doors and frames replaced. We will definitely be using his services again! Thank you so much Constantin!
