“I cannot recommend Dennis and his crew enough. They were professional, personable and kept to the set timeline. I appreciated the constant communication and asking for my feedback throughout the project. They cleaned up every day and the finishing project is top notch. Even the glass installer commented on the quality of the work. I will definitely be referring friends and family and will always have Dennis is mind for future projects!”
Jennifer H.“I can’t express how extremely happy we are with the work Dennis did on our kitchen, I am absolutely obsessed with the outcome! From the beginning to end he did not disappoint. We had him install subway tile and hardware in our kitchen (and custom windowsill). He guided us through the process, explained what product would be the best for our kitchen and the best quality! Not only did he do an amazing job but he was very respectful to our home and was very understanding as I was going through a family issue. We will definitely be referring him to all of our friends and family…also to all of my Real Estate clients and fellow Realtors. Thanks Dennis so much for the amazing work and can’t wait to reach out to you for our next project!”
Jessica S.“Don’t hesitate! DM Knapp Construction recently completed full remodels of our main bathroom plus two secondary bathrooms. They are gorgeous!! Dennis is the ultimate professional. His pride of workmanship shows in his projects. His tile work is masterful! He took care to respect our home, kept a clean job site, was there when he said he’d be, and was excellent corresponding with us. Dennis does his own work (with a very capable employee) and stayed on the job through completion. (He didn’t disappear for days at a time, like some contractors will. We couldn’t be happier with our completed bathrooms and highly recommend DM Knapp Construction!!”
