You should be very proud of each and every one that touched our project, not to mention our lives. ❤️ > Patti & Mickey Foti **★★★★★ — DC, Sept. 2023** > We first worked with J&J when we were looking to have a skylight installed in an existing bathroom. We liked that Erik came out and reviewed the space in person and made recommendations as to size and location (another contractor actually gave us an estimate without even looking at the space!). We were comfortable with the J&J quote and went ahead to schedule the work. Several weeks later we had a spring hail storm that moved through the area. We ended up needing to have our roof replaced and our insurance company gave us the ok to work with whomever we liked. In addition to having J&J quote the roof, we had at least one other contractor quote it (a group that had done work in our area). A third contractor we had worked with in the past wasn’t even able to come out to look at it for 6-8 weeks. We ended up going with J&J for the roof work because 1) we liked how Erik presented their approach and explained the process and 2) they were best suited to coordinate the skylight install at the same time and keep us on track with that work. Dave the project manager then got involved, came onsite to review things, kept us informed of the schedule/timing of when materials/crew were going to show up, etc. It was, admittedly, a messy project (first full tear-off for a 100+ year old house). The crew worked late the first night and we honestly weren’t happy with some mess left behind in the dark. Dave addressed our concerns right away and things went very smoothly after that. We’re happy with the work and subsequent follow-ups. Should be have other projects, we would definitely engage the J&J team again. **Comment from J&J Contractors I LLC:** > Thank you very much for the kind review, we appreciate your business and trust in J&J. We look forward to the opportunity to work with you again in the near future. **★★★★★ — Andy Dineen, June 2023** > We used J&J Contractors to replace our entire front door and surround and do some other rotten wood replacement. They did an awesome job. Evan and Tony were so easy to work with. Very communicative throughout the entire process. Tony made sure everything was done to the highest quality standards. Something was missed and he even came out on his own time to correct! I cannot thank them enough for the great job and quality work. I would highly recommend and will use them again and again. **Comment from J&J Contractors I LLC:** > Thank you Andy for your business and trust in J&J! **★★★★★ — HU-277716811, May 2022** > J&J replaced our aging roof shingles, rain gutters, and down spouts. The new materials and professional work have refreshed the exterior of our home. Dave, our project manager, was wonderful to work with! Dave is organized and very good at coordinating the materials and tradesmen. J&J did a fantastic job on our house! **Comment from J&J Contractors I LLC:** > Thank you for taking the time to share your experience with J&J, we're happy to hear Dave took great care of you and your home improvement project. **★★★★★ — Kathy Weidner, Oct. 2021** > Our Son referred us to J&J contractors when we were looking for new windows and patio door . > Seeing what an amazing job Jason’s team did on Brian’s exterior we knew they were the right fit for us too. > What a beautiful transformation the 16 windows and patio door made. > The experienced crew was professional and did an excellent job of installation. > Evan was very helpful in coordinating the efforts of our project. > We highly recommend J&J contractors . > Kathy and Gary Weidner **Comment from J&J Contractors I LLC:** > Thank you for choosing J&J and for your trust in our team! We're happy to hear that they did another fantastic job! **★★★★★ — Lynn Bartoszek, Sept. 2021** > We had a new roof and gutters installed on our home. They kept us informed on the schedule and did a great job. We've used them for our basement remodel as well and have been very happy with their work. **★★★★★ — Jennifer Pollock, April 2021** > We have used J&J for four different remodeling projects. The most recent was for a Velux skylight installation. Once again they did a great job. I have recommended them to many friends. **Comment from J&J Contractors I LLC:** > Thank you for your continued trust in J&J, we're happy to be your \#1 choice of contractors! ## Selected projects - [Custom Home Build](https://www.houzz.com/hznb/projects/custom-home-build-pj-vj~6162407) - Location: Waukesha, WI - Photos: 38 - [Brookfield Master Spa](https://www.houzz.com/hznb/projects/brookfield-master-spa-pj-vj~6097958) - Location: Brookfield, WI - Photos: 15 - [Cedarburg Custom Home Build](https://www.houzz.com/hznb/projects/cedarburg-custom-home-build-pj-vj~6097964) - Location: Cedarburg, WI - Photos: 24 - [Brown Deer Kitchen](https://www.houzz.com/hznb/projects/brown-deer-kitchen-pj-vj~6566017) - Location: Brown Deer, WI - Photos: 9 - [Muskego Basement Remodel](https://www.houzz.com/hznb/projects/muskego-basement-remodel-pj-vj~6588651) - Location: Muskego, WI - Photos: 16 - [Mequon First Floor](https://www.houzz.com/hznb/projects/mequon-first-floor-pj-vj~6116225) - Location: Mequon, WI - Photos: 15 - [Waukesha Cabana](https://www.houzz.com/hznb/projects/waukesha-cabana-pj-vj~6635522) - Location: Waukesha, WI - Photos: 15 - [Elm Grove First Floor](https://www.houzz.com/hznb/projects/elm-grove-first-floor-pj-vj~6097992) - Location: Elm Grove, WI - Photos: 12 - [Mukwonago Master Bathroom](https://www.houzz.com/hznb/projects/mukwonago-master-bathroom-pj-vj~6588648) - Location: Mukwonago, WI - Photos: 5 - [Complete Home Remodel](https://www.houzz.com/hznb/projects/complete-home-remodel-pj-vj~1804392) - Location: Greendale, WI - Photos: 26 - Description: This 1960’s ranch began with a closed off floor plan that was unfitting of this families desire for a coastal design open concept home, that was built for entertaining.
