Jim Casali was the contractor responsible for my home repair project. The repairs were being made due to storm damage. This review is being written as a thorough recommendation of Mr. Casali and his services based on his knowledge, interpersonal skills, and professionalism. Mr. Casali’s knowledge of his trade was extremely impressive during every step of our renovation process, which included the roof, chimney, siding, windows, and insulation replacement and installation. Additionally, we had repairs to drywall, wall paint, windows and door trim, a full sunroom replacement and the demolition and rebuilding of a new pressure treated deck. He was also instrumental in communicating with our town zoning and building inspectors, as well as working with our insurance adjustor and structural engineer. His knowledge, guidance, and assistance allowed us to focus on our life and family, which was very comforting. Mr. Casali made a sincere effort to build a relationship with our family, including my children, from the first day we met. This was a tremendous help during the most difficult of times. It was clear that our project was important to him and not just another job and he demonstrated sincere empathy and patience with us, as this was our first project of this magnitude. Our family and the circumstances we were in were clearly a priority to Jim, and that should not be understated. While establishing a trustworthy relationship, Mr. Casali was extremely professional at the same time. He arrived on time - every time, answered calls and texts in a timely fashion, and provided comprehensive details of each task and procedure throughout the process. We always felt that our questions or concerns were respectfully heard and answered, and we were promptly accommodated if we had special requests or adjustments. It is with tremendous confidence that I recommend Jim Casali for building, remodeling or the renovation of your home.

Jim, we want to thank you again for all the hard work that went into our new house addition. The new room came out excellent! If anyone needs more info. as to our experience here is what I would tell them. First, your attention to detail and the guidance you gave us from the very start to the very finish was certainly very helpful. We were faced with many decisions along the way from the plans to the final construction. I know at times, things were a little stressful with the delays from the town permits to the final C/O. But you displayed patience with us and helped us understand the process. Going back to detail, you were very meticulous on each phase of the work by your subcontractors ensuring completeness and accuracy, as well as cleanliness after each phase was completed. All your sub-contractors were also so courteous and helpful in many ways. Before each phase of this construction, you took much time with us to explain the details of things like the Plans, the Survey, the Footings and their placement, the Boxing of the base, the Framing, the Wiring, the Insulation, the position of the Lights, the Thermostat and the Outlets, even the Hurricane Brackets which was totally new to me!! You were exact on your measurements on things like the placement of the windows and doors. You were very informative on guiding us on the type of windows we should get to the style of the French Door. The Radiant Floor Heating you put in was superb! The final painting of the trim work and the walls were the final touches that made this room come together. I also appreciated your suggestion on the shoe moldings, this certainly added an aesthetic appeal to the room. When getting into a project like this, we found things that we needed to change. You were accommodating on the Change Work Orders and your frequent Progress report was certainly a big help. We kept within our budget on this room which otherwise we could not do very well without your help. In regards to staying on schedule, we faced the weather woes going into the fall, but you made time to keep the job on pace by getting your subcontractors to work on the weekends. We learned a lot from this experience and we are very glad we chose you and your team do this project. I did not need to go to any other contractor as I already lived in a well-built house by you and your dad 20 years earlier. The final comment; is your follow-up. We certainly appreciate wanting to know that things like the heat, the windows etc. we’re performing well long after the completion. We would certainly recommend you to anyone that is looking to build a house or add a room or two. Thanks again for all the hard work and the excellent work performed!!! You certainly are a PRO!!!

It was a pleasure to have worked directly with Jim Casali. His Professionalism was obvious from the first time we met. Jim showed his expertise at the planning stage, during the construction and well beyond the completion of the project at our lake home. When working in the existing part of our home Jim’s team plastic wrapped everything and sealed off the area with a wall of plastic tarp. The team cleaned up daily and was extremely conscientious of the furniture, floors and walls. I enjoyed an active collaboration throughout the entire project with Jim. Unlike other contractors Jim was available after hours and on the weekends by phone or to meet for discussions. I am the first to admit I require more interaction and handholding than most. Jim was always available for me. There were plenty of 9:00pm calls to discuss this or that. The most important aspect of building an addition or new construction is being able to trust your contractor, your partner in the project. After hearing all the horror stories I thank my lucky stars I decided to choose Jim Casali. Jim’s building practices aren’t just about the construction. Jim’s gift is recognizing the wants and needs of his clients and executing them properly. We discussed options and together made the best decisions for our project. His workmanship was outstanding, that of great craftsman. My wife and I are ecstatic with our 3,000sf addition and have gained more than just a contractor we have gained a friend. I would recommend Jim Casali without question.

We hired the Casali’s to build our home, and the experience was nothing short of fantastic. From start to finish, they were thoughtful, communicative, and truly committed to bringing our vision to life. Not only did we get to build our dream house but they made sure every detail was tailored to our lifestyle and needs. They were accommodating, collaborative, and incredibly respectful of our time, budget, and ideas. What stood out most was their integrity and the pride they take in their work. Any issues we had were quickly resolved, and accommodated by Jim and the team. We’re now living in a space that feels uniquely ours, and that’s because of the care and craftsmanship they put into every step. We now have someone we trust that we can go to for any addition, repairs or renovation needs. Highly recommend to anyone looking to get a renovation or build a home with people who genuinely care. Thank you!

I made a decision to move from Dallas, Texas to Connecticut, and purchased an almost 200-year-old house in New Milford. We knew there were many renovations to be done to the house and property as it had been neglected an earlier owners and the property allowed to fall into foreclosure. There were broken pipes throughout, ceilings that had been water-damaged, rotting floors, broken windows and many other things that had to be updated. We knew our trips back and forth from Texas to Connecticut would be very few so we needed a contractor whom we could entrust with the tremendous responsibility to making our old farm house a comfortable and safe home. Jim Casali proved to be the very person we needed, a company we could trust. And our trust was not in vain. Jim proved to be the man of integrity who earned his reputation by meticulous attention to detail, absolute integrity and transparent openness in dealing with us. Every change order was explained to our satisfaction. Jim went out of his way to make us happy. It is a privilege to recommend Jim Casali to anyone who wants to work with a company that can be trusted to keep its word, do its best and produce a finished product one can be proud of.

Jim and the Casali team did a remodel of our master bedroom and bathroom as well as our kids' bathroom. The old master bathroom / bedroom layout didn't work and we needed to relocate some doors, extend the master bedroom entry out into our hallway, relocate ceiling AC vents and move nearly all of the plumbing. From the beginning, Jim took the time to meet us and review the space, work up multiple floorpan options, and take into account the potential pitfalls and limitations that come with an existing home. His ideas for how to rework our master bathroom and bedroom have transformed that part of our house and we're very happy with it. The crew worked hard, put in long days and cleaned up at the end of every day, being very respectful of our home at every turn. I would work with The Casali Companies again without hesitation.

I had the good fortune to have found Casali to undertake the refurbishing/renovation of my medical office building. Casali has finally broken the stereotype I always held to be true, that of builders being late, unreliable and untrustworthy. Since inception of the project at my medical building not a day went by without the Casali crew being on site and working away. Always on site at 7am made a pleasant change from previous experiences with other general contractors. All in all I can wholeheartedly recommend this company, from the strength of their workforce, technical understanding and efficiency; they have made my project a relatively painless one.

Office Interior renovations at Banta Direct Marketing Group began at our facility with lots of excitement. The company wanted to reinvest and make some major renovations and update any necessary printing equipment. We spent a lot of time on architect drawings prior to the actual renovation stages and were very specific to detail and clearly stressed the expedition factor. We had no reason to worry with “Casali” on the job. Casali rebuilt offices and their mission was to expedite all necessary work without disturbing any of the Banta workers, which had their own work to complete on a daily basis. When Banta workers moved any of the press machinery for refurbishing, The “Casali Crew” moved right in and replaced the floor tiles and further expedited the project at hand.

It gives me great pleasure to write this letter to recommend the Casali team. We recently, in the last two years, were involved with Jim Casali and his team in 2 commercial retail renovation projects. One just completed in New Canaan, CT. I would highly recommend working with Jim Casali and the Casali team. Jim Casali, owner and project manager, is professional, efficient, timely and thorough. Both projects came in on planned budget and on time. When working in old buildings there are always surprises, Jim Casali was totally professional in dealing with all obstacles. The quality and attention to detail by Jim Casali and the Casali Team is rare today. I highly recommend this company!

We feel completely confident in their ability to complete every job according to their client’s wishes.

Thanks to the Casali team on the recent addition, renovation, and septic system of our summer home. We found your company very reliable and all work is of excellent quality. Your guys on the job always displayed excellent workmanship and were always punctual, polite and cleaned up after themselves daily. We were particularly impressed at the quality workmanship and would like to extend our thanks to the team. Many thanks again – when I eventually need more work done, I’ll be in touch.

Hi Jim, I just wanted to let you know how much we’ve been enjoying our new space. It was so nice to have all the extra room for the holidays. We still look around and can’t believe how amazing it turned out! Thank you for working with us on all the changes and always listening to any concerns we had along the way. It was a real pleasure working with you, and I can’t thank you enough!

We have had the pleasure of working with Jim over a 7-month period and his work was first class. We had structural and substantive upgrades done to our lake home and could not be more pleased with the finished product. The project was done on time, within budget and with excellent craftsmanship. We would be glad to show off Casali's quality workmanship and design.
