John and his team did excellent work to transform our unfinished 1960s basement, stairs, and landing leading down to the space into a beautiful, comfortable, and livable space for our family. We were impressed with the skill, personability, and professionalism of his crew, and we appreciated the regular communication and updates about the project and progress. We had multiple other contractors tell us that our vision wasn't workable with the age and condition of the basement, but John worked with us to find the best solution that still fit our budget. JP Grabenstetter's work has added valuable living space to our home, and our family is already putting it to great use!
Very thankful we went with John and his team for our basement project. All members of the team were professional, skilled, and kind to us. Communication was great on a weekly basis of what basement items would be finished during the week and they consistently stayed on schedule. Added a full bathroom, entertainment center shelving build-in, and they made selecting materials very easy with recommendations and perfect pairings. Going to tell all of my friends to use JP Grabenstetter!

I am delighted to share my experience working with the outstanding team at JP Grabenstetter. From start to finish, the entire process was a seamless and enjoyable experience. We are absolutely thrilled with the results of our finished basement, which far exceeded our expectations. John and his team took the time to carefully listen to our vision and wish list, ensuring that every detail was considered. The final design not only incorporated all of our requests but also included thoughtful recommendations that enhanced the overall functionality and aesthetic of the space. The craftsmanship is truly exceptional—it's clear that the team is highly skilled in their trade. What truly set this experience apart, however, was the level of communication. From the initial consultation to the final walk-through, John and his team were consistently responsive, transparent, and professional. Any questions or concerns were promptly addressed, and we always felt informed and confident throughout the entire project. I wholeheartedly recommend JP Grabenstetter and his team to anyone looking for high-quality work and a stress-free experience. We would not hesitate to engage them for any future projects.
We found John via great reviews and his focus on basement renovation. We had been under construction for almost 3 yrs. with a main kitchen project with an inept contractor. To say we were gun-shy on hiring another contractor for the basement is an understatement. After obtaining 3 estimates, John’s came in several thousand less than the others. Not only did John and crew begin earlier than scheduled, they finished earlier as well! Watching the ease of each crew coming in, finishing their work (that is their area of expertise), cleaning up and without any delay, the next crew came in and kept the work going - his crews have been with him for years! Even his payment process is set up in an unbelievably efficient manner. The results speak for themselves - we are thrilled with our new basement apartment; John and team literally transformed the lower level of our home. (See before and after pics). We highly recommend JP Grabenstettar Construction.
John and his crew did a awesome job on our basement. He always kept us up-to-date and on schedule. Total area finished 1,300 sq ft. with plenty of room left over for walk in storage. We definitely recommend JP Grabenstetter Construction to anyone.
