I had a two bedroom apartment flood with several inches of rainwater, and David did a total renovation. He was able to start quickly and finished the whole job in under two months in perfect condition and under budget. Very easy to work with and a good communicator. The job was tough because it involved coordinating with other tenants in the building to make sure their services weren’t cut off any more than necessary, and he handled that very well too. **★★★★★ — Chris McCaffrey, Sept. 2021** > Modest but rush job, which made it even more impressive to me that Dave and his team jumped on it and were responsive every step of the way. Honestly, one of the best interactions I've had with area contractors in the years I've been here. Quality work, reasonable pricing, stayed within budget. I'd recommend and would hire them again myself. **★★★★★ — HU-445345744, July 2021** > David and his team were great for our house renovation. We set up the project prior to our closing and they started work 2 days later. The project was on time and came out fantastic. We did a full gut of our kitchen and removed a wall to open the floor-plan. David was able to reuse the existing cabinets and we built an island that matched them. He was great adjusting to changes in the plan. **★★★★★ — Dan Carruthers, July 2020** > After purchasing my home recently, I needed the main beam in my basement replaced and supports on my back deck repaired. Being new to the area, I was unsure of who to hire but after reading many reviews and getting several estimates, I was very happy to have gone with David. He was great to work with from the initial estimate through the completion of the project. His team, led by Louie, was fantastic. They worked fast and performed quality work and were also very communicative through the entire process. His pricing was very fair and he communicated with me any additional costs that arose during the project, which were very minimal. The crew was even able to perform an additional repair on my house next day after after a delivery truck knocked cabling off my house. I would highly recommend David and plan to use him and his team again in the future. **★★★★★ — Sharon R, Aug. 2018** > David is professional, knowledgeable and kind. We started working together in 2017 on two bathroom projects and then began a large project renovating most of our first floor, including a kitchen. I would recommended David Mangini & Co. without any reservation. **★★★★ — Storm Damage, Dec. 2017** > I had extensive damage to my house repaired by David and his team. Considering this was unplanned and unexpected, I received excellent and prompt service with a restoration better than the original construction standards. **★★★★★ — Peter Garber, Jan. 2017** > I knew of David from his work a neighbor's project. In 2015, he removed and rebuilt my deck and in 2016, I contracted with him to add a room over my garage and to re-roof, re-window, and re-side the house. A large project, the work started on time, finished on time, completed on-budget and with excellent result, and was carried out without interruption and with great attention by David and his crew. David was very creative in his suggestions and problem work-arounds. He and his crew were very pleasant to work with, and they strove to minimize the disruption that was unavoidable in a project this size. **★★★★★ — jfarnen63, July 2016** > David was referred to us by a well-respected masonry contractor who I know well. David was a complete pleasure to work with throughout the course of the project. He spent countless hours working with us to develop an understanding of our needs and put together a wonderful design for a complete home renovation. In addition to his General Contracting skills, he is a master craftsman who lent his expertise to the finishing touches on our project. David's work stands for itself, and he is as good of a person as he is a craftsman. > > Jim Farnen > Westport, Connecticut **★★★★★ — Bruce Taylor, Dec. 2015** > We are a ‘repeat’ and delighted customer/client of David Mangini & Co. Did I mention delighted? Sound unusual? Although builders and contractors have reputations that are generally rated below bill collectors and Members of Congress, our experience with David Mangini has been just terrific. > > We found David (accidently) through THE kitchen designer of Fairfield County. And within days, we knew we had the right team. Project plan; communication, regular up-dates, attention to detail, quality workmanship, and creativity are all part of David’s business plan. And, his crew shows up before you make the morning coffee. No guessing. > > Perhaps the most important element is that David – personally – makes every project better. He sees things that others (architects, designers, etc.) miss and can make suggestions to improve the outcome and wisely save (and/or spend) money too. > > Repeat and delighted customers/clients are difficult to find in any industry. David Mangini & Co. is highly recommended – but only if you are prepared to be delighted too. **★★★★★ — david78815, Dec. 2015** > Dave has been a wonderful resource to us for projects large and small in repair and renovation of our home. Unlike many contractor he does not shy away from difficult problems and always finds workable options to choose from. **★★★★★ — drcorona7, Dec. 2015** > David Mangini & Co.recently completed a total renovation of our 21 year old kitchen. The final product is as stunning as it is inviting and we could not be happier. Naturally, a two month journey from "studs" to stunning can at times be overwhelming. In our case however, David Mangini's creativity, craftsmanship, attention to detail and unique ability to guide us through every stage of the process provided constant reassurance and optimism. Our faith in David was not misplaced...On time, On Budget, On point. I would strongly recommend David Mangini & Co. for your next project. **★★★★★ — Elisabeth Sloan, Architect, Nov. 2015** > As an architect, I found David Mangini Co., LLC, a pleasure to work with in all stages of the design and construction process. Dave is a positive facilitator, enhancing the relationship between the owner, architect, and the construction team. With over twenty years of experience, Dave brings extensive skill to the areas of cost estimating, phasing, and construction administration. His knowledge of high quality residential construction is evident in all stages of the project. He has an excellent team of plumbers, electricians, HVAC, masons, and talented carpenters required to complete a major renovation and addition. Dave is very good at guiding the owner through the design and construction process. His powerful communication skills are evident in his ability to work with local building and zoning officials. He is quick to ask questions, when needed for clarification and also to respond to question. His thoughtful and conscientious methods create a beautiful project. His careful planning allowed the owners to continue living in their home, as his team moved from one area of the renovation and addition to the next one. He keeps the site neat and clean. He is friendly, funny, and kind to family pets. He regularly visits his job sites and coordinates the work, several times throughout the day. I strongly recommend David Mangini Co., LLC for your next project. ## Selected projects - [Darien Custom Home](https://www.houzz.com/hznb/projects/darien-custom-home-pj-vj~1370025) - Location: Darien, CT - Photos: 5 - [Greenwich Kitchen](https://www.houzz.com/hznb/projects/greenwich-kitchen-pj-vj~5557274) - Location: Greenwich, CT - Photos: 10 - [Custom Bathroom Remodel](https://www.houzz.com/hznb/projects/custom-bathroom-remodel-pj-vj~5774968) - Location: Norwalk, CT - Photos: 3 - [Westport Kitchen](https://www.houzz.com/hznb/projects/westport-kitchen-pj-vj~1391876) - Location: Westport, CT - Photos: 4 - [Baths](https://www.houzz.com/hznb/projects/baths-pj-vj~1373373) - Location: Norwalk, CT - Photos: 8 - [David Mangini & Company, LLC Receives 2020 Best of Norwalk Award](https://www.houzz.com/hznb/projects/david-mangini-and-company-llc-receives-2020-best-of-norwalk-award-pj-vj~6291365) - Location: Not specified - Photos: 1 - Description: NORWALK June 8, 2020 -- David Mangini & Company, LLC has been selected for the 2020 Best of Norwalk Award in the Construction & Remodeling category by the Norwalk Award Program.
