"WARNING: PLEASE BE EXTREMELY CAUTIOUS BEFORE USING THIS COMPANY I had a very FRUSTRATING and COSTLY experience. I paid $616 for a repair to fix a water leak under my toilet, but the issue was not resolved at all. One day later, when I contacted them again to report that the problem was still ongoing, I was told they would now use a ?second option? and was quoted an additional $1,539.35 (Total cost: $2155.35). When I requested that the $616 I had already paid?especially since the issue was never fixed?be applied toward the new work, they refused. Instead, they insisted I pay the full amount again and sign the invoice before they would proceed. This raised SERIOUS CONCERNS for me about both their pricing and overall service practices. I ultimately hired another professional who completed the job for $869, which further highlights how excessive their charges were. BASAED ON MY EXPERIENCE, I STRONGLY WARN OTHERS TO BE EXREMELY CAUTIOUS WITH THIS COMPANY. "

"Mike and his team at MDK Remodeling did an amazing job on our new Trex deck. They were friendly, professional and very easy to work with. They were very communicative on the project and with updates required from our township. Would definitely recommend MDK for remodeling needs."
