Introduction

I have twenty-seven years construction experience, including seventeen years being a self-employed contractor. I specialize in interior remodeling and pride myself on the quality of the finished product. When you contract with me, it will be me doing all the critical work. When I start a project, I do the work right the first time and don't have to go back to fix mistakes. If your ever unsatisfied with a detail of the project, I will return to make it right. I pride myself on the quality of the finish and durability of the work. Being self-employed is great. You provide the creative energy and I'll provide the know-how and get the job done. I enjoy the fact that my business is part of my life, not just a j-o-b.

Hired on Thumbtack

Jason was extremely kind, quick, and efficient. He came with everything he needed and more, and installed a door for us pretty quickly - a job that surely would’ve taken me many hours and it probably would have been hanging incorrectly. This was a small job but I will be hiring Jason for bigger remodeling jobs in the future!

Details: Interior door, like a bedroom or closet door • 1 door • Sliding glass • Mixed materials, like wood with windows • No, but the door frame exists • Yes, I already purchased the door • Home

He arrived on time and put up a tarp screen to contain the dust. He cut the granite to fit the new cooktop and it fits perfectly!

Details: Granite • 21 - 30 sq ft • Yes, I will supply the materials to the professional • Residential
