We had DeBernardi redo our steam room. He gave us an accurate estimate, brought samples of stone and plumbing fixtures to our home for approval, handled all plumbing and electrical needs, protected our home from any accidental damage by his subcontractors, cleaned up the work area daily and gave us a finished product that we were so happy with that we now have asked him to redo our sauna also. We found all of his subcontractors to be very pleasant, professional and skilled. I would highly recommend him for any remodeling projects you might have.

Our remodel went extremely well. A blend of our ideas and Joshs design recommendations resulted in a beautiful end product. DeBernardi and their subcontractors were always professional, prompt and did neat, quality work.

When we tell people how enjoyable building our new home was, they dont believe us. When we tell them what a great collaboration we had with DeBernardi and his crew, they say "that never happens." Well, it did for us. Not only did Jeff build us a quality home, he did it in a timely manner, he was always professional and always inspirational. Bottom line: he wants to satisfy his customers and build a great product. Jeff brings talent, tireless energy, pride, and a strong work ethic to his clients. We would recommend him to anyone and we have done so many times!

Communication was always open as was flexibility during our project. We hired DeBernardi because of a friends high recommendation and in turn we recommend his company without hesitation.

We had Jeff do basic bathroom remodel for us, after he built our friends home. We were a little hesitant as to whether he would want to do a smaller job for us, since he was building entire homes. He told us that the smaller jobs were "filler jobs" and that he would get everything ordered and at our house, then when his guys were a little slow he would send them over. We waited for over a month after we got the vanity, countertops, tile and plumbing fixtures and were honestly starting to get a little anxious so we called him. He said we were on the schedule for the following week, and did in fact show up then. What amazed us is that the guys had the whole bath torn out in a day, then had the new bath put together within a couple days after that! I think the total time to finish once they started was about 6 days! Needless to say it was worth the wait. The work was neat and there was no "punch list", other than a small ding in the wall paint which we just touched up for them. Our house is newer so we don't have any more projects, but if we did we'd hire DeBernardi again in a second.
