5.0 Kaitlyn O. Bellingham, MA

Working with Jack Whealan means that you're working with the best. My family had a rather complicated project that included 3 major phases along with painting and refinishing existing floors. Not only did Jack complete the majority of the project independently, but he did so while seamlessly coordinating subcontractors to keep the process running smoothly. Jack kept us in the loop every step of the way, and delivered a product that is superior to any other project we've had done. Jack answered all of our questions around the clock, and made sure we had the information behind his answers. He provided great insight about so many things in the home (whether they dealt with the new build or not). You can tell that Jack is a person who genuinely cares about the work he is doing. He is meticulous and detail oriented, and he won't install something in your home that he wouldn't put in his own home. If I had to go back before this project was started and choose a contractor to work with, I can 100% say I wouldn't choose anyone but Jack. You seriously can't go wrong with Strong Builders. It was a pleasure to work with Jack and we are so happy with our new home.

Response from Company:

Thanks Kaitlyn! Appreciate the kind words and [given a present job I'm enduring] really appreciate great clients. It was my pleasure to assist your family and you. There are never too many questions providing they are done respectfully and in deference to relative knowledge regarding the application and duration of my craft. You're whole family did just that I am pleased and grateful for your feedback.

Jack designed and built a family apartment and screened porch for us as well as adding a separate bedroom and bath to the main house. It was a relatively big job that Jack did 90% by himself, demonstrating his amazing knowledge and skills in contracting and building. I was amazed at the quality of work and the commitment to the job, working 12-hour days in some cases. Jack was onsite every day, doing almost all the work himself. Absolutely stunning work. I recommend Jack to anyone who wants top-notch, high-quality work.

Response from Company:

Thanks Walt! Your family and you were amazing clients. Thanks again for the Xmas present. FYI, I don't wear that one to work - it's too nice

5.0 Derek K. Upton, MA

Strong Builders built a new deck for us, and it came out amazing. From the beginning, Jack was an excellent communicator helping us understand the process and get to a solution. He was clear and transparent on the pricing, and found him very competitive. His work was done very high quality, and get the job site clean throughout the process.

Response from Company:

Thanks Derek!

5.0 Lisa A. South Grafton, MA

My pressure treated deck needed staining every year so the time came to upgrade. Jack from Strong Builders did an amazing job from the planning stage right through finish and cleanup. He provided many options to look at and helped me find the right colors to match my gazebo and complement the patio stone. Once the materials arrived he worked quickly and was done in a week! The outcome is beautiful -clean lines and detailed work. One excellent feature is the way the screws are hidden so the walking surface remains smooth. I highly recommend and am very likely to use Strong builders for future projects.

Response from Company:

Thanks Lisa!

5.0 Ricardo R. South Grafton, MA

Jack is simply The Best, period! He is not just a master carpenter, he's a craftsman that not only understands the importance of quality, he personally owns it. My wife and I have already asked him when he's available for our next project! Be patient, he's booked solid most of the year, but you will not regret it! We've had much experience with other builders/contractors, and they all-except for Jack-have a something that leaves one with a bit of frustration or disappointment. I NEVER felt any of those with Jack: a true professional! We'll never hire anyone else! Feel free to call/text me if you don't quite believe: Rich in Grafton at 617-304-1786

Response from Company:

Thanks Rich!

5.0 Sarah W. Northborough, MA

We'll never hire anyone else again - Jack from Strong Builders will be our only contractor as long as he's in business!

Response from Company:

Thanks Sarah!

5.0 Caitlin S. Hopkinton, MA

Strong Builders remodeled our basement and added a bathroom. Jack had a clear vision of the project and he communicated very clearly with us throughout the process. Jack also had an amazing attention to detail. The basement and bathroom look great. We enjoyed working with Jack and we look forward to working with him again on future projects.

Response from Company:

Thanks Caitlin!

5.0 Brian M. Upton, MA

Jack was true to his quote. Did everything he said. He worked alone on the entire job from start to finish. He did not outsource thus keeping the project of a high quality.

Response from Company:

Thanks Brian!

5.0 Brian G. Worcester, MA

Strong Builders did our screened in porch. Working with Jack was fantastic. As one of his previous review's states "renewed my faith in contractors" is absolutely true. He was punctual, had great communication, was clear and up-front about everything. His experience reflected in his work. He is meticulous but efficient. He clearly takes pride in his work. Probably the most bind-boggling thing is that he does the vast majority of the work himself and by himself. He knows the building codes in and out, which made getting permits approved as smooth as it gets in a county that is notorious for being difficult to build in. Jack refused to cut corners and confidently stands behind his work. We will absolutely hire him again and cannot recommend him more.

Response from Company:

Thanks Brian!

5.0 Brandi T. South Grafton, MA

Our experience with Jack from Strong Builders has renewed my faith in contractors. He provided clear communication about the project and cost with no surprises. I asked a lot of questions, and he always took the time to explain things to me. Jack completed the project with impressive attention to detail and beautiful finish work. It was a stress free process, and I can't recommend him enough. Our second story screened on porch is our new favorite part of the house!

Response from Company:

Thank you.
