I am so happy we got to work with Chris. The work came out beautifully, and the process itself was much easier than I imagined (not easy, exactly, since we did a lot of work and lived in the house through the renovation… just not nearly as painful as it could have been). Even as we hit some hiccups relating to work that had been done incorrectly 25 years ago, I felt like every day things were happening and there was always progress.  We had a lot of moving pieces and he was a wiz at scheduling them so that when one step was done the next step immediately started. I also really appreciated his advice - if I asked a question looking for advice based on his experience he actually answered it - as a first time home renovator that was invaluable.  He was super responsive, easy to work with and the sub/ contractors were great too.

Mike, you and your crew were extremely prompt and professional everyday… You promised me a completed job within 3 weeks approximately, and you came through. I can’t believe how fast my kitchen was completed from demo. to framing. planning, electrical, sheetrocking, painting, trim. windows, sliding doors, tile, cabinets. granite and all the final touches within an amazing time frame… It’s so nice to find a contractor who is professional, talented and reliable… I’d be happy to be on any referral list you may have, in order to help any potential clients make the right decision by hiring you!

During construction your men showed up everyday at 7 am and worked until 7 pm, they were clean and respectful on and around my property, and took the time to do even the smallest of details with the utmost care. Things were done correctly and efficiently… We have received many compliments from family, friends, and neighbors that are impressed with the quality of work and the time frame that it was completed. They have all asked the same question “Where did you find the guy?” We happily gave them your name and number. My wife and I couldn’t be happier with the work that was done to our home. We feel extremely lucky to have found you as a contractor and to have the opportunity to work with you.
