I do not believe you could find a more conscientious and skilled team than those at Mangiantini Construction. I did a major remodel, and the process of planning and designing was conscientious and meticulous. John is a very talented builder and designer. But what I will always remember most was how much emphasis he placed on getting it right during the planning stage. His staff is superlative and hard-working. And the result is that when I look around, I am so glad I did this! John is always available to answer questions and give advice and guidance. He emphasizes quality, service, and continuity
