What Our Customers Say
Unsolicited five-star reviews from real homeowners across Southwest Michigan.
"We had a great experience working with Jeff. He was very knowledgeable and informative. When helping us decide the types of material and look we wanted to go for with our new deck. He made the process simple and it turned out great! Couldn't recommend them higher!"
- Cassie Casabona
"They delivered without a hitch. Professional, responsive, knowledgeable, and fairly priced. My front stoop and deck feel fresh and reliable — if you're in the market for similar work, they're worth checking out."
- Kevin Barnes
"Jeff and his crew were awesome! My project was a bit different, being a treehouse on a steep ravine. They communicated clearly, worked quickly and aided me in decisions to ensure a successful project. These guys are a pleasure to work with. I highly recommend Semper Gumby construction!"
- Samuel Sims
