Get matched with top addition to existing structure builders in Northborough, MA

"My wife and I were looking to have an addition built on our 2 bedroom / 1 bath home back in the winter of 2022. After a phone conversation with Richard, we decided to have him come out to the house. He was very clear with the iCornerstone process, and the benefits of using this process. He is meticulous in measuring and understanding the existing structure. There are no guesstimates and all cost projections are based on the actual materials and labor needed to complete the work. Having such clarity regarding costs before any work begins is not something I've seen in this industry prior to this experience. It was certainly a welcome change. We now have plans for a home addition and complete control over the project. We decide the scope and can customize the plan to our budget. We are grateful to have worked with Richard, and highly recommend him!"

"They were great. We are very happy with how everything turned out!"

"Jack just completed an addition to our home, and we could not have asked for a better builder experience! He is organized and efficient, his work is excellent and the result is a wonderful addition that we are enjoying! Jack is responsive, straightforward and knowledgeable. He also built our neighbors home 6ish years ago and they love it and have not had any issues. We highly recommend working with String Builders and Jack. We plan to work with him for more house projects in the future!"

"All of my projects were completed with top notch quality and in a timely manner. They were very professional and highly skilled. I would recommend them for any project needs. The specific projects they completed for me were: remodeled 2 bathrooms, 2 complete basement remodels, interior painting, exterior painting, deck, siding and trim repairs, hard wood floor refinishing, and complete kitchen demo and install."

"Work went very well. They were quite thorough and easy to work with. Very pleased with our new deck."

"Did excellent work! Was professional, honest, and explained how the process works. Equally as important to me is that he answered all of my questions. Admittedly, I can be overbearing in that regard, so I genuinely appreciated his patience. Highly recommended and look forward to having other projects done by him and his team when my budget allows for it again."
