I had a great experience with Constantine! He was responsive and easy to work with. He installed two patio doors in my home and he was honest and fair throughout the whole process. Looking forward to hiring him for additional projects in my home.

I hired Constantin to install 2 security doors and he did an outstanding job. He used the doors I requested, installed the knobs and locks as well and completed the job efficiently and with high quality. He even helped adjust the inner doors to ensure all doors closed and locked as needed. I highly recommend him for any door installation or other similar work.

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.
