We had Strong Builders do a full remodel of our kitchen. We couldn't be happier with the quality of the work, or the transparency that Jack provided throughout the entire process. Jack's the best and what he does, and we highly recommend!

Response from Company:

Thanks Brian!

Jack did a fantastic job. Five stars for all his work including quotes, sketches of proposed work, professionalism and workmanship. When I contacted Jack in the summer he set clear expectations when he could provide me with a quote and he was very punctual with it. After inspecting the work that needed to be done, he provided several options and was very patient with the follow up questions. Once we finalized on the option, he worked very fast to get the necessary paperwork. He did all the work himself and with high quality. He even helped me with a contact with another contractor for something unrelated to the job that he was doing. Jack communicates very well, and he always answers e-mails and texts promptly. We highly recommend Jack, and we would gladly hire him for future projects.

Response from Company:

Thank you Shree! Always a pleasure to work for clients who appreciate our commitment to the trades

We hired Strong Builders to replace our carport and deck with a new 1-car garage and composite deck, and the results exceeded every expectation. The finished product truly blew us away — everybody that has seen it has commented "wow", including inspectors that look at these things every day. The garage turned out so beautifully, that we almost don’t want to park a car in it! We chose Jack because his pricing was competitive and his professionalism and attention to detail during the quoting process far surpassed his competitors. He was a pleasure to work with during design, offering thoughtful guidance and helping us make the right decisions for the project. Throughout the build, Jack was meticulous, kept the property spotless, and communicated clearly about his schedule and plans. His work ethic was remarkable — the amount he accomplished each day was impressive. We would recommend Jack and Strong Builders to anyone seeking top-tier quality, integrity, and true professionalism.

Response from Company:

Thank you Matt! It was my pleasure and it's a joy to work for people that notice the difference

Jack was responsive, communicative, attentive to our needs and delivered as specified….right down to the last details. He took care of everything from permits to product. We could not be more pleased with the outcome.

We interviewed 3 contractors for our kitchen remodel when I finally did an google search for local contractors in my area. I read a review of Jack from Strong Builders that was so impactful, it actually brought me to tears. We met with Jack and could not have be happier with our decision. Jack is a rare find these days. He is trust worthy, reliable and very skilled at what he does. Jack showed up day one of the project, parked his trailer and was there 6 days a week, 8-10 hrs a day! He is organized, methodical and keeps a clean job site. He was very honest about the expectations of the project, when minor issues arose, they were handled and addressed with ease. Jack works diligently to see the project through to completion with his goal of “no callbacks”. Strong Builders, one guy, one project at a time. I would recommend him over and over!

Response from Company:

Thank you Amy! It's always a pleasure to work for clients who appreciate our commitment to the craftsmanship required to deliver projects like yours.

We hired Strong Builders for a major home project, and the results were exceptional. Jack, the owner, is everything you hope for in a contractor — professional, punctual, and deeply experienced. He handled the design and construction of our new deck and sunroom, and also remodeled our living room by removing walls and reimagining the layout. What impressed us most was Jack’s honesty and follow-through. He’s a great communicator, clear about timelines and costs, and he always does what he says he will — a rare quality in this field. He does most of the work himself, so there’s no guessing who’s responsible for quality, and he’s an excellent problem solver when unexpected challenges arise. If you’re looking for someone who’s hands-on, reliable, and highly skilled, we strongly recommend Strong Builders. You’ll get great results with no surprises.

Response from Company:

Thanks Andy! Always nice to work with great clients

Jack did an incredible job engineering an open floor plan for our traditional colonial home. He was able to thoughtfully pull together a plan and execute it from start to finish. It was a complicated assignment with multiple rooms coming together as one integrating our kitchen. Through our collaborative planning, Jack has created an incredible open floor plan where we can enjoy all areas of our home including a new pantry and storage. Jack is a consummate professional and works with precision and focus with the job at hand. He communicates well and manages the project as a master contractor and doer of the project. I highly recommend Jack and Strong Builders for your next home project.

Response from Company:

Thanks Penny! Always nice to work with great clients.

You won’t regret hiring Strong Builders for any project. Jack was great to work with, from beginning to end. He built a 16x18’ family room with a 16’ cathedral ceiling. Jack was on-site everyday and completed almost everything himself - framing, siding, windows, roof, sheetrock, hardwood floor, fireplace/mantle, painting, deck. Jack provided daily updates and was very transparent when it came to costs associated with the project. He was very courteous of us still living the in house during construction - with two young kids. Jack’s attention to detail, from paperwork to carpentry, is second to none. Strong Builders will be my go to for future projects.

Response from Company:

Thanks Kyle! Marylee and you are excellent clients. Enjoy your new Family Room

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.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.

  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
