Our Customers Say

“From the first meeting this company impressed me. I planned a few projects in my backyard, but didn't realize we had a drainage issue that was causing excessive moisture in our basement. The team identified the drainage issue and the moisture has never returned to my basement. I appreciated their holistic approach and their attention to detail. I love the new look and the added useable yard the new retention wall created. This company is experience and honest.”

Joy S. Backyard Makeover

“Gabriel Maggio Construction stepped in to rescue my failed master bathroom project, transforming it from a disaster into a masterpiece with exceptional craftsmanship. Impressed by their work, I hired them again to build a stunning carriage house-style detached garage and completely revamp my home's exterior with a new roofline, porch, deck, and siding. From design to completion, they were amazing to work with—professional, detail-oriented, and truly committed to excellence!”

“I'm a real estate investor who has worked with Ron Maggio through many projects, some going back decades. The quality of the construction and communication has always stood out. Most importantly, when issues came up his follow up and attention to the root cause of complex issues keeps me coming back”
