From Our Customers

”We met Todd Cote of Trinity Construction following the floods of 2006. We hired Trinity Construction to restore our finished basement and create shelving in our unfinished basement. We were so impressed by his quality workmanship, his professionalism, and exceptional work ethic we have since hired Todd to build our deck, create our sunroom, install new roofing, and install our generator. We feel so blessed to have Trinity Construction as our contractor. We highly recommend Trinity Construction to all our friends and neighbors.” (Randy and Marsha K.)
