"I have been an architect for 45 years and worked with hundreds of contractors, Firestone Builders is one of the finest. On-time and on budget on every project and responded almost immediately with every question or call. Firestone Builders is a problem solver, not a problem creator. I would highly recommend them for any project."

"Joe at Firestone Builders was able to propose out of the box ideas that fit my budget. He is not like other contractors that propose unnecessary and costly ideas, rather he is a solution-oriented/out-of-the-box thinker that will solve whatever space constraints that you may be working with. He is very timely and understands being on a deadline. I would recommend 100 percent! "
