It was definitely time for some love, and Sidex really came through for! What stood out most was the crew and how they treated my grandparents like family and were genuinely so kind throughout the whole project. Really glad we chose them!

From the first phone call to the final walkthrough, the entire experience was outstanding. The team was professional, punctual, and incredibly knowledgeable. They took the time to answer all of my questions, communicated clearly throughout the project, and paid close attention to every detail. The quality of their workmanship exceeded my expectations, and the finished deck looks absolutely amazing. They treated my home with respect, kept the work area clean, and completed everything on schedule. It’s rare to find a company that truly delivers on its promises, but Sidex Siding & Decking did exactly that. If you’re looking for a trustworthy, skilled, and reliable contractor, I highly recommend them. I couldn’t be happier with the results and will definitely use them again for future projects. Five stars all the way!
