“We’re absolutely thrilled with our new deck and patio! Miguel’s professionalism and friendliness made the process enjoyable and stress-free, and his company’s craftsmanship and attention to detail are evident in every aspect. Overall, we couldn’t be happier with our experience with Fortress Construction. A big thank you to Miguel and his entire crew!”

-Frances

“Fortress Construction LLC built a screened-in porch for us. We are very pleased with the results. The day-to-day crew was very knowledgeable, efficient, and the result of their work is a porch built with very high quality. I would definitely recommend Miguel and Fortress Construction LLC for your project.”

-Steve

“A top shelf experience. The work crew that showed up knocked it out of the park. The mason took his time and made sure the job was going to be something that I wanted to enjoy for years to come. I’d use Fortress for any job. This is the way you want to experience working with construction pros. Thanks, Miguel and Crew!”
