Basement Renovation

Very satisfied with the professional work I’ve received. Highly recommend this business for any future remodels.

Mike from Mullen customs created our dream home by adding a second floor addition, his attention to detail was the best experience we have had with contractors. In addition his team completed our siding, roof and installed new windows and doors before the estimated time of completion. He was so honest and reliable we called him back months later to add a deck on our home. Highly recommend!

My husband and I bought a fixer-upper in 2015 and spent the last decade navigating the DIY world. By the time we got to our basement project, we were ten years in and completely fatigued—so we decided it was finally time to outsource. We had prior experiences with work where corners were cut, and the regrets that came with that. So when we met Mike, the difference was immediate—and honestly, refreshing. From the very first interaction, he was clear, reliable, and professional. His contracts were straightforward, and throughout the entire project, he consistently did exactly what he said he would do. When adjustments were needed, he communicated proactively and transparently. Mike truly looked out for our best interests at every step. Our bathroom demo was not an easy one, but he problem-solved through every challenge and transformed the space into something I never could have envisioned. What stood out just as much was the efficiency. We were used to projects dragging on for months with minimal progress. With Mike, it was the complete opposite—on the very first day, I left for work and came home at lunch to find the entire bathroom already demolished. The full project was completed in about a month. Even after the main work was done, when we ran into a few issues related to plumbing (not caused by Mike), he went above and beyond to make sure everything was addressed and that we were fully satisfied. I truly cannot recommend Mike highly enough. He took on a challenging project and made it look easy. Worth every penny.

Great work and fine craftsman ship. Efficient and professional… highly recommend.

Amazing!!! Mullen customs completed our upstairs addition and less time than scheduled and it looks amazing, highly recommend!! I called him back months later to complete our deck.

Mike Mullen and his crew came and replaced my entire roof in East Norwalk in 2025. They did exactly what they said they would do, when they said they would do it. On time, on budget and left everything beautifully clean and tidy. Mike is a skilled professional, honest, fun and I highly recommend his services. Thanks Mike, Gratefully, Nicola

We recently hired Mike Mullen to replace all of our siding, windows, and exterior trim, and the experience was exceptional from start to finish. As a local real estate agent, I’ve worked with countless contractors over the years, and Mike continues to stand out as one of the best in Fairfield County. He delivered on time, on budget, and with incredible attention to detail. The entire project was managed in an organized, thoughtful, and clean manner—something that’s hard to find with large exterior jobs. Mike was transparent throughout the entire process, communicated clearly, and made sure we always knew what to expect. I’ve recommended Mike to many of my personal clients for major renovation and construction projects, and every single one of them has had the same outstanding experience. His craftsmanship, professionalism, and reliability are second to none. We’re already planning our next phase with Mike: a full addition off the back of the house and a complete interior remodel. I wouldn’t trust anyone else with it! If you’re looking for a dependable, skilled, and honest contractor in Fairfield County, I highly recommend Mike Mullen. You’ll be in great hands.
