Client Testimonials

“FSO and John have been wonderful to work with and his pricing has been excellent. All of the information is timely and he is very responsive. I will be purchasing all future buildings from FSO and I truly appreciate working with an excellent company.”

Everything went as scheduled down to the minute. I got a price on my metal building that could not be matched by anyone. I even had a salesman call me a liar when I told him what my quote was. Also, when they say there is going to be a delivery at 8 in the morning on a certain day, you better be ready at 8 in the morning. No fuss, no muss. Perfect.

The building turned out great! Could not be happier with the quality! Me and my dad built it from the ground up just us. It’s finally done so time to load it full of projects! Thanks for the help and the quality building!
