On recommendation from our son, we chose J&J Contractors to put a new roof on our house and garage. We met with Dave Bartz our project manager, and we were impressed with his willingness to work and ensure that our project would be managed properly and exceed our expectations. We agreed on the scope of work, and were informed on how each step of the project would be completed. All of the workers were professional and courteous; and the clean up was excellent each day. We are extremely pleased with the finished roof, and highly recommend J&J, Dave Bartz and the entire work crew. Jerry and Janice Hempel

Proj. Mgr. Josh and the whole crew did an excellent job on our floors. From ripping out the carpet and ceramic floors to the sanding and refinishing the wood floors, to the laying of the new LVP to the finishing of the shoe molding in all three rooms. Each person that was here was so very professional, friendly and knowledgeable. We've used J&J in the past when in our old house and we got the same type of service then as we received now. I'd recommend J&J (and have many times in the past) to any of my friends, family and neighbors.

I've had multiple home improvements done with J&J and the attention to detail with quality work and craftsmanship is superb. Justin recently finished up a punch list after a remodel and let me say he went above and beyond. Thank you again for another outstanding job.

Excellent company to work with! Salesman,Erik and Project manager Dave both went above and beyond before project, during and after project! Communication was great! Erik secured the hole in my roof very effectively til job able to be scheduled.Dave came after job complete and removed shingles that fell into attic from the hole and reconnected my fan vent to roof vent very effectively. This was very much appreciated! Crew was courteous and respectful of property with efficiency, quality and excellent clean up. Excellent company overall and would use in future and recommend them highly!

very well. The project manager always responded to questions and calls quickly. all workers were polite and on task. The 2 drywall workers who were there alone almost all the time, did not speak english at all, which made communication difficult.
Response from J & J CONTRACTORS I LLC
"Thank you for your business and the review, we're sorry about the communication difficulties with the drywall work and we'll try to address this issue."

J&J Contractors just put a new roof on our house and has an efficient and professional group of workers and project management that was really appreciated. J&J Contractors removing old roof & gutters and installing new roof and gutters. I certainly recommend them.

The work went very well except for a problem they discovered when old flashing removed. Had to revise cost of project. Pictures were taken and forwarded to me and several discussions took place trying to explain to me the problem and additional cost for labor and material. They purchased material quickly and the cost of material and labor was half of the amount we agreed on. It took an additional morning to complete but they did a great job cleaning up each day including sweeping the area for nails. The total project was completed without any down time, very timely. Very satisfied!

The project went fine. This was a complete roof including all decking boards. All employees, sales, front office, and onsite professionals demonstrated a strong work ethic and quality work. The roofers had to work around extreme weather conditions , always keeping me informed of progress and flexible schedual. Very Personable, punctual and diligent.

J&J remodeled our kitchen and did a fantastic job! Hands down the best contracting company I've ever worked with. Everyone was so responsive and kept in great communication with us on the status of our project - not to mention friendly and fun to be around. They worked very quickly but didn't compromise the quality of the work done. I will definitely work with them on any other projects in the future.

We loved working with J&J for our kitchen and bath remodel! From the very beginning of the project they were very professional and always communicated clearly through every stage of the project. Our project manager, Adam, was always checking in to make sure things were going smoothly and being done correctly. He was very easy to work with and made sure all of our requests were being met. All of the subcontractors did high quality work and went above and beyond. We also had a great interior designer who was able to help us made decisions which was very helpful! In addition, they completed the whole project in a timely manner! We can't wait to have them help with our next project!

They did a satisfactory job. There were no unexpected issues. I think they did a good job. I think their prices, in one instance were fair and in another instance, were overpriced.
