★★★★★
I cannot say enough good things about Anthony and Sentinel Contracting. From start to finish, Anthony was professional, dependable, and easy to communicate with. He was upfront about pricing, stayed within budget, and kept everything moving in a timely manner—which is incredibly hard to find with contractors these days!
The quality of his work is outstanding, and it’s obvious that he genuinely takes pride in what he does. He pays attention to the details, doesn’t cut corners, and makes sure everything is done correctly. His pricing is fair and affordable without sacrificing the quality of the finished work.
If you need someone trustworthy for a renovation or new home build, I would absolutely recommend Anthony and Sentinel Contracting. Professional, honest, skilled, and reliable—the total package!

★★★★★
I hired Sentinel contracting to complete my backyard permit approval on some footings that needed to be added. Anthony was able to meet building inspector expectations and knows requirements. We then proceeded to work on a project of making my backyard porch into a three season room and it was a really nice well done job. Anthony and the team are professional, give suggestions and recommendations on what will work or not. They are detailed and clean work. Communication is great.
