“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

“We’re absolutely thrilled with our new deck and patio! From beginning to end, Miguel’s professionalism and friendliness made the entire process enjoyable and stress-free, and his company’s craftsmanship and attention to detail are evident in every aspect of our deck and patio. 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 recently completed a screened-in deck at our house. Miguel was able to take the vision in our heads and present us with the options to make it happen. He even helped us navigate the Special Permit process in Fairfax County to be able to get the deck size we wanted. The team worked hard to move the project along quickly while still maintaining exceptional quality in their work.”
