What St. Louis homeowners say about us
“We had a crew of two assigned to our 12 day build. Manny and Grant were excellent. They showed up on time every morning, cleaned the job site up at the end of every day, took the time to make sure that everything was precise, level, and exact… The deck looks awesome, it’s rock solid, and turned out even better than we expected.”
“Since then, I have walked around looking at the fence’s perfect alignment, and finally, I just could not stand it any longer. I had to apply a level to some of the posts… they are standing straight up!”
“Working with Nick Maniaci was great. He was easy to communicate with (which is definitely not always the case with contractors), and his guys did good work.”
