Testimonials
EXCELLENT Based on 55 reviews Posted on Krissie MorrissetteJanuary 11, 2026Trustindex verifies that the original source of the review is Google. Can’t say enough good things about JB Cote Construction!! I’m a single woman who had an ADU built. During the entire process, I felt safe and confident that the owners and the whole crew had my best interest in mind. They walked me through every step of the process. The price they quoted included everything. They were kind, prompt, creative, professional, available, and did a fantastic job! So happy I found them!!!Posted on Anthony MartensSeptember 8, 2025Trustindex verifies that the original source of the review is Google. JB Cote was able to build a beautiful staircase at my home which allowed me to get access to my backyard. From the estimate (on time, great price) to the execution (professional crew, on time and on budget) JB Cote delivered what they said they would with excellent craftsmanship. One of the challenges I had with getting this work scheduled was a lot of other contractors ghosted me. JB Cote arrived when they said they would, gave me a fair estimate, kept me in the loop on timing, scheduling, and material selection. I will certainly consider them first for any additional work at my home.Posted on Kara PrideJuly 25, 2025Trustindex verifies that the original source of the review is Google. My husband and I strongly recommend J.B Cote Construction. They have recently completed some renovations for us and we were greatly impressed by their professionalism, quality of work and their attention to detail. Their office staff was very responsive and courteous. We would definitely hire them for our next projects. Thank you J.B Cote Construction and to your support contractors for a job well done.Posted on John GuertinJuly 2, 2025Trustindex verifies that the original source of the review is Google. The Cote family and their crew did a great job on my mini split system and some repairs. Communication is great and they show up when promised. Neat work with no mess. The hard part of getting a mini split price is the equipment used and the routing of the lines varies significantly . I have seen installations where it looks like an octopus is on the house and there are huge coils of lines behind the condenser. Cote construction took the hard route and routed the lines inside the house out of sight wherever possible even when it was extremely challenging to do. The pictures speak for themselves. I agreed on a routing that would have been much more visible and easier and they changed it on the day of installation to be much cleaner.Posted on sean crowleyMarch 22, 2025Trustindex verifies that the original source of the review is Google. After a long period of debating whether or not to sell my home or to renovate my existing home, I decided to stay and hire JB Cote Construction To completely renovate, my kitchen and finish a room with a half bathroom in the basement. From our first meeting, Brian was very affable and easy to work with. His Experience in this field was clear from our first discussion. The entire team from Phil, Rui, Nate, Beth, Travis and Tyler treated my time, home and most importantly my son and I with respect and honesty. As the project progressed, they were very As I made several changes and additions to what we had initially discussed. As a small business owner myself, I can often be tough to please, but they accommodated my needs perfectly. They kept me up-to-date on changes with the schedule or on product availability, and even though I added many things, it only added a few extra days to the Original schedule. I’m very happy with the Completed work And I am already considering additional projects I may request their help with. I would highly recommend Brian and his team to Anyone that should need their services. Thank you all for a job well done.Posted on Michael HebertFebruary 23, 2025Trustindex verifies that the original source of the review is Google. Brian and his team have outstanding attention to detail and completed our first floor renovation well ahead of schedule. They treated our house with as much care as we would. Highly recommend!Posted on John GinolfiJanuary 5, 2025Trustindex verifies that the original source of the review is Google. If you’re considering a home renovation, look no further than J.B. Cote Construction. They recently completed a full demo and rebuild of our kitchen, living room, and breezeway, and the results are beyond what we could have imagined. This was a big project—they handled everything: demolition, insulation, tiling, flooring, cabinets, plumbing, electrical, appliance installation, and even wire management for the TV. They covered our old stone fireplace, installed an electric fireplace, knocked down a load-bearing wall, installed a 14-foot support beam, moved windows, and added a slider. They even took care of the finishing touches like hanging window treatments and mounting the TV. The crew showed up every day at 6:50 am on the dot, except Mondays when they started closer to 8 am because of their weekly team meeting to prep for the week ahead. Their organization and attention to detail were incredible, and it showed in every part of the process. What really sets them apart is how personal the experience was. Brian, the owner, and his crew felt like family. They were respectful, friendly, and just great to have around. My kids actually got attached to Rui and Phil, and when the project was finished, they were sad they wouldn’t get to see them every day! It says a lot about the kind of people they are. Even after the project was done and fully paid for, Brian and his team kept in touch. They reached out multiple times to check in, and when we noticed small things like a squeaky basement door, they were back within a day or two to fix it. That level of service and care is hard to find. If you’re looking for a contractor that does exceptional work and treats you like family, I can’t recommend J.B. Cote Construction enough. They made what could have been a stressful renovation feel seamless, and we couldn’t be happier with the results!Posted on David CroutearDecember 12, 2024Trustindex verifies that the original source of the review is Google. I had new floor tiles installed in my kitchen and bathroom. I also had a Generac Generator installed at my home. I contacted J.B. Cote Construction to take care of all the required work. I am happy with everything I had done. I would recommend J.B. Cote Construction to my family and friends if they were looking for a contractor to do renovations or install a home generator. They take care of everything from start to finish. J.B. Cote Construction does quality work and are experts in their field.Posted on Chris BlessingDecember 10, 2024Trustindex verifies that the original source of the review is Google. Brian and the crew at JB Cote installed 29 windows, 3 doors and a slider at our home. They treated our home like it was there own making every effort cleaning up each day. They went the extra mile replacing a bathroom fan exhaust cap that been missing on the exterior of our house for Years. Never mentioning it. Couldn't recommend them enough and can't wait to work with them on our next home improvement project.Posted on Roberta HunterDecember 10, 2024Trustindex verifies that the original source of the review is Google. JB Cote Construction did a fantastic job redesigning our backyard including a larger deck, and beautiful patio area around our new pool. In addition, they updated our master bath and divided a bedroom into a walk in closet and office space. They listened to our ideas and made suggestions throughout the projects. The quality of work was excellent, they responded quickly to emails and phone calls, the workers were professional and cleaned the work areas each day, the jobs were done in timely manner. We were so satisfied, that we have them returning to update two bathrooms in 2025.
