My Family and I can’t say enough about Mike and Fabio! We highly recommend Mullen Customs LLC. Mike and Fabio came to our house on the agreed date and time. A few days later we received our estimate for our kitchen remodel. We decided to go with Mullen Customs LLC. They took out our full kitchen including the floor in 5.5hrs-6.5hrs. Three days later all the cabinets were in awaiting the quartz counter and island tops. Mike and Fabio keep you informed every step of the way. We had Mike set up our floor install, plumbing hookup, painting, quarts and back splash install. (All went smooth!) Mike is an excellent project manager. He would tell you the next tradesman is coming and they would come as expected and quickly perform their jobs. Mullen Customs LLC offers excellent workmanship and fair pricing. My wife and I believe Mike and Fabio are in a class all their own. We will use them again for any other projects that comes up. Todd & Jen (Stratford Ct)

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!

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.

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

It is my pleasure to give Mike and his great team my highest recommendation. His vision for what works in a space and attention to detail is amazing. The layout and cabinets he chose transformed my space. And my floors look incredible. Mike also communicates about the process in real time and got the remodel done exactly on schedule. His estimate is competitive and accurate, which I also appreciated because I had little slack in my budget. Can’t wait to see what he does with the rest of my house. Thank you to you, Mike, and your great team.
