Mangiantini Construction
Website
First, we enter into a design and planning agreement and define a scope of work based on your vision, goals, and budget range. Our design team creates a preliminary floor plan prior to the design phase. A solid planning process upfront saves time and money. It all starts with a vision, a solid plan, and sound design to make our clients' dreams come true.

Our primary goal is listening to your needs, hopes, and budget so we best design for your lifestyle, comfort, and peace of mind. We want you to love living in your home after we have finished our work. If you already have drawings when we meet, we'll happily work with your design professionals to build your project.

Managing the building phase will require extensive oversight. Mangiantini's building projects have a track record of running smoothly, devoid of unexpected changes and budget inflation. John's experienced approach and oversight ensure each project's objectives and timelines are met. Mangiantini is your Contractor for Life.

I have had a working relationship with Mangiantini Construction for several years. They have been my go to for projects big and small. When we decided to remodel our kitchen there was no need for conversation regarding finding a contractor, Mangiantini Construction was our first and only call. They are professional, honest and communicate throughout the project. I highly recommend Mangiantini Construction.

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

Mangiantini Construction has renovated four homes for us over the years and with each project we experienced complete satisfaction with The Mangiantini Team's approach. Our renovations came in at budget, on time and with the results we were expecting.

John Mangiantini is a great contractor and we highly recommend him! We worked from start to finish with him on a "gut, back to the studs" remodel; this could have been a difficult emotional roller coaster ride. John made the entire process as comfortable as possible. His even keeled manner helped us through it all. He offered helpful suggestions along the way which were invaluable. John was always immediately responsive to all our needs and concerns; a quality not often encountered with other contractors. We are extremely pleased with the work he and his sub-contractors did. There are always problems

We hired John for a major remodel of our 65 year old house, and couldn't be happier with the process and results! At the initial meeting with John to discuss what we wanted to do and what was possible, he was friendly, professional knowledgeable. He was able to give me a 'reality check' on the cost of a project on the scale we were considering. After deciding to move forward, we met with his wife Jennifer for some kitchen design ideas and then worked with their in-house architect Jeremy. Jeremey was great to work with and gave use ideas of how to re-work our space in ways we never dreamed of, giving

The work itself was top notch and John has a great temperament for working with picky people (which we have reluctantly come to realize describes us). He addressed all of our requests – he really made the house into everything we hoped it would become.
