“I found someone who understood what I wanted and was able to deliver. Very experienced, knowledgeable, quality material with an excellent price. They did my screen porch with an attached deck. I love it, my neighbors love it, and all my guest love it. Good communication. It really exceeded my expectation. I am so glad I went forward with this project and chose Fortress.”

-Bryant

“I would recommend Fortress Construction to anyone seeking a reliable and professional contractor who does quality work. The best part was that I was able to stay in touch with Miguel via text and email and he responded promptly to answer any questions. If I had another job to get done, I would definitely go back to Fortress Construction.”

-Geeta

“We have nothing but good things to say about Fortress Construction and their work. Miguel and the rest of his team built our dream deck and were very professional, punctual, and transparent. There were no problems with the inspections and the deck itself was beautiful and built with detail and care. Overall we could not be happier with our new outdoor space.”
