Don't just take our word for it.

See what our past clients have to say. 

TJ Costello is great. He was exceptionally helpful during all phases of our kitchen extension and renovation. He is very patient, took all of our ideas into consideration and added so much value to the overall project. I would highly recommend him!

I find him to be very innovative and he does a great job modernizing in a unique way. T. J.’s ability to bring a home up to date without sacrificing the style keeps the building timeless. If you have the opportunity to hire someone of this stature it is well worth its value.

The staff at Heirarchy is fabulous. They did a renovation and addition to our house and we absolutely love it. Not only are they creative and smart, but they also helped with all of the approvals with the town. They made our house functional for our family while maintaining its original character and charm.

TJ and staff did a major renovation to my house. We added three bedrooms, family room, new kitchen, including a master bedroom and bath. The transformation was unbelievable and everything I dreamed of....I enjoyed the whole process and it was well worth it! It was a pleasure working with them and they did a fantastic job on my house!

Dear T.J., I LOVE my new kitchen! It isn’t quite finished yet, Dan still has to do the backsplash. The tiles have been ordered and will come in 2 weeks. I can not thank you enough for your expertise, your vision and especially your patience during this process. I could not have done it without you. The  small details make the kitchen and you provided these details. You are welcome over any time. It was a pleasure working with you.
