"Frank and his team with GMZ Contracting exceeded our expectations for building a new deck. We have owned multiple homes over the years and hired out lots of work, and Frank was without question the best contractor we have ever worked with. He provided us with a free estimate, and then followed through on everything he said he would do. His team showed up early every morning and worked all day until the job was done. Honestly, watching them work was fascinating because they worked so efficiently as a team and accomplished so much each day. Frank is the ultimate professional - delivering top quality work with integrity and great communication throughout the project. We will hire Frank and GMZ Contracting for all future work of ours, and will recommend them to anyone we know."
