Why homeowners choose Maniaci
The people who walk your property on day one are the same people you'll see every morning until the last board is down. That's the reason the quality stays consistent from job to job — and the reason we can put a multi-year warranty behind it.
"I cannot praise Ryan and his most excellent crew enough on their professionalism, work ethic and talent. We could not be more pleased with our new deck. Even the county inspector praised the work."

What St. Louis homeowners say about us
"We had a total nightmare of an experience with a previous deck contractor… Maniaci Construction completely restored our faith in the trades. The framing is perfectly secure, the lines are straight, and the finishing details are absolutely stunning. They even made sure everything was perfectly permitted and passed the St. Louis County inspection with flying colors."
"Ryan came right out and drew up plans for a pool deck. I was impressed by his professionalism and how he listened to everything that I wanted. Our pool deck turned out amazing! Our whole family loves it. I have asked them to install a privacy fence next."
"We had previously received a couple of other quotes for a new deck. Upon meeting Ryan and immediately detecting his knowledge, experience, honesty and integrity, we decided to have him build our new backyard deck… We highly recommend Maniaci Construction Inc."
