Diana Christine on J&J Contractors I LLC

From the start to the finish our Project Manager made sure to keep us on schedule and updated with progress. Even though this project occurred during the winter months, they were able to navigate the unpredictable weather. This company made sure to secure the construction zone so that our living space was comfortable while the addition was being built. We are so pleased that all the workers, project manager, and other support staff helped us achieve our beautiful dream of a lake view from our new bedroom. I would highly recommend J&J.

It was long held dream to add a full bathroom to my basement- Finally, J & J helped make that happen. It is gorgeous! I got everything I wanted, and J&J came up with great ideas to make the most of the space. Alejandro, my project manager was super!- friendly, communicative, timely, and did all he could to answer my questions. J &J's work is high quality- I couldn't be happier!

Andi Zimmerman on J&J Contractors I LLC

After using J & J for a new gable and entryway, and house painting jobs we hired them for a 3rd time to re-do the primary bath.

Once again, the J&J team led by our project manager Alejandro was a great experience. From the initial designs, product selection and construction everything was delivered on time and on budget with no surprises. Communication was always timely and responsive.

We highly recommend using them for any remodeling needs.

We would highly recommend J & J Contractors for roof replacement & window coverings and would definitely consider them for future projects. All of the staff were great to work with, very pleasant & cooperative. We couldn’t ask for a better team all around! Our roof & windows look great!

LOIS PUIDOKAS on J&J Contractors I LLC

We are in love with our new kitchen! We love how bright it is and how much storage we now have by adding drawers and the pantry cabinet. J & J delivered quality work and communicated closely throughout the project. Although a kitchen remodel is never "easy", the timeline was adhered to, and we were able to get back to cooking again in a short time frame. Thanks J & J!!!!
