Major Renovation of Multiple Rooms
John and his team are ABSOLUTELY TERRIFIC and i would highly recommend. I had just purchased a home that had been partially renovated by the previous owner. John did a full basement finish, outdoor deck rebuild, front stoop/landing rebuild, repaired/installed a garage roof, replaced windows and doors (interior and exterior), and many other projects related to these and others that arose throughout the project. John’s work was excellent, on time, and within budget. He was also friendly and easy to work with, sending me weekly status updates including both timing and budget. On multiple occasions throughout the project he identified unforeseen issues (e.g. rotted wood, debris that needed to be removed, pipes that were incorrectly installed or cut) and kept me updated and fixed the issues. John also handled ordering all parts (with my consultation) e.g. , handles, doorknobs, wallpaper, doors, hooks, etc. I highly recommend John and his team for any project.

John performed a major renovation on our house recently, remodeling the entire first floor, including kitchen, bathroom, closets and a patio as well. He met with us frequently to update progress and include us in the process. He always answered phone calls and texts. He and his crew arrived on time each and everyday. They contained the mess and kept the work site neat and clean. His crew was trustworthy and did high quality work. Highly recommend John and his staff!

My family had the pleasure of contracting John and his crew to remodel our kitchen. We live in a nearly century-old house that was not properly cared for by the previous owner, and our original kitchen showed it. John helped us plan out a full remodel with new cabinetry, countertops, appliances, flooring, and ceiling (the latter two were originally slanted and uneven). He was communicative and thorough during the planning phase and his crew was always on time, professional, and thorough during the actual construction work. John was on site each day to supervise and keep us in the loop on how things were progressing. They caught multiple major structural/functional issues along the way that they were able to fix without it even impacting their timeline for the project. Thanks to John, my family now has a beautiful, functional kitchen. We will definitely be reaching out to him when we start additional projects in our house!

We recently completed a major multi room renovation which included a new kitchen and den renovation requiring an expansion of our foundation along with removal of exterior and interior walls. Additionally the reno included a new back deck and front portico. We could not be happier with John and the job that he did. What impressed us most with John was his reliability. Over the course of this 4+ month project, John was at our house first thing each and every weekday morning, and had his team there as well. They were professional, courteous and kept the house clean and functional enough that our whole family was able to live in the house while the renovations were taking place. John initially quoted us that the project would take 4 months and they remarkably stuck to that schedule. The end result has been everything that we wanted. The pictures speak for themselves, but the craftsmanship and attention to detail they put into the project were exceptional. John was forthcoming with suggestions or advice, and very transparent when any changes or surprises popped up. He was truly a partner in the effort and we would strongly recommend him for any projects that you may have. Sincerely, Ann & Steve Marcus

We had been looking to renovate a laundry room and an adjacent powder room for several years. The project involved making the laundry room smaller and expanding the powder room to allow for an easy access full shower for an elderly family member with mobility issues. While the available space didn't allow for full ADA shower John Marzano used his decades of experience to plan for maximum use and accessories necessary to meet our needs. John met with us several times and listened to our wants and needs. The workmanship was excellent, the tiling involved large format porcelain tiles for the shower walls that are almost 4' by 4' each. He promised that he would handle it, along with the shower pan, back splash behind the vanity, and the new tile floor. We couldn't be happier, and everyone that has seen it says it's the best tiling work they have ever seen. Same accolades go for the carpentry work, placement of the grab bars and and shower fixtures. His advice was spot on from the planning phase to project completion. In short, we would absolutely use him again and would recommend him with 100% confidence to our friends and family.

John is a nice guy. We were on a budget which he understood and respected. We remodeled two bathrooms at the same time. The end result was very impressive considering our budgetary constraints. He finished when he said he would and his crew were clean and courteous.

It's nice when a contractor actually does what he says he will do. John is a super, hard working man who has a fantastic crew. They all take the utmost pride in their work. We more than doubled the size of our deck and he did a beautiful job. We're quite pleased. Thanks, John!

John and his guys did a great job on my bathroom, turned out beautifully!!!! He's affordable and kept me in the loop every step of the way. After the end of day, he and his guys cleaned up and even helped get my faux wooden floors back in place in my dining room/living room. (Didn't even ask but he and his guys did that anyway, much appreciated. I'd ask him to come renovate the rest of my condo when the time comes. Thank you John and guys!!!!!!!

Out bathroom turned out beautiful. We are very happy with it. From the start, John was able to give us a vision for the remodel that nobody else did. The team was courteous, on-time and cleanly throughout the whole process and did everything they said they would and more. The price was fair and the work excellent.

JM construction is the best. John is very knowledgeable, offers great suggestions and basically just knows what heâ  s doing. They do not outsource. JM does all the work themselves. Would highly recommend this company.

In 2020, JM Contracting Group, LLC re-modeled our kitchen and did a great job. They are honest, hard-working and diligent in making one's design dreams come true. So we asked them to come back and re-model our bathroom in 2021. Once again, they rose to the occasion with another successful job completed. What is nice about working with JM Contracting Group is their willingness to address any specific requests that you have. They will discuss all of the appropriate pros and cons ensuring the best outcome for the project. We truly enjoyed working with the group and would highly recommend them.
