About

My name is Alex. I am professional in a construction. I can do all construction works and I do my job very professionally. I have over 5 years of hands-on experience in window and door installation in the United States, and prior manufacturing experience in Europe. I don’t just install products — I understand construction details, waterproofing, insulation, structural framing, and long-term performance.

Hired on Thumbtack

I contacted Alex and he came within 20 minutes. He fixed a broken door jam for me and left it looking great. He cleaned up the job site and was responsive. I appreciate the good work and speed. Will call him for any future projects. Thanks Alex!

I do a lot of canvassing before I hire somebody, he's the cheapest quote I got and I was so happy with the outcome. He's very dedicated and knows what he's doing. Will definitely contact him again for the next project.
