Client Testimonials

  • A truly positive experience.

    Isaac and his team at JIH Builders did a detailed and well constructed job when providing complete construction for my 6 family property. They demolished and rebuilt the structure and the entire process was professional and well coordinated. The team is very knowledgeable in all aspects of the industry and were willing to share their expertise to assist my concerns throughout the process. From expediting, to approving permits, as well as everything else, I was at ease in the knowledge that I was under the direction of such a reliable and reputable team. I trust in them completely and they took the reigns until the house was ready for tenants to move in. The detailed reports were listed to the last cent and I look forward to continued business together.

  • Role reversal.

    With JIH, I feel the roles have been reversed in a positive light. Instead of having the pressure of following up with the contractor, he follows up consistently. Instead of worrying, the worrying gets done and solved for you. That sums up our positive experience with Mr. Hirsch at JIH. They do what needs to get done and that matters.

  • No regrets, just accolades.

    At our very first consultation with Isaac, my team and I were impressed at his business acumen and were confident with his methods. He has proven to be the right man for our projects and didn’t disappoint our initial expectations.

  • Accompanying us from our early days.

    Isaac’s knowledge and professionalism surpass that of any GC firm I’ve previously worked with. I am extremely happy with the process and people behind the JIH vision and recommend his staff and service for a job well done. Aside for the task management, Isaac personally makes himself available to meet or discuss our standard and, sometimes unconventional, concerns. This personal take on communication truly matters in the industry and their clarity in progress reports eases the process. We have already moved on to a new project together and wouldn’t consider using anyone else to get the job done. A true mensch and pleasure to deal with.

  • Exceeded expectations on multiple levels.

    There’s no one I’d rather have at my side than Isaac, when it comes to project development. Isaac and his team are responsive and pay attention to every project as if it were their own equity at stake. We are currently in the midst of a ground up development project with JIH Builders Group and we’re hitting progress that exceeded expectations. The team at JIH remains focused on delivering high quality at a most efficient cost and provides priceless expertise to every real estate project. I’m fortunate to be working with the best and look forward to many more projects in the future.

  • JIH saved the day.

    Isaac has proven his commitment and expertise when working with us on a recent and complicated project. We were faced with complications during a recent major renovation in a mostly occupied building. Isaac and his team delved into the options and offered us more than just a service. They patiently devoted much time and attention to detail, which ultimately resulted in a successful project. Isaac succeeded in having all violations removed and a new Certificate of Occupancy was received, thanks to his intuitive approach.

  • The team that makes it happen.

    I started my first project with Isaac and the JIH team and was impressed by their expertise in the industry. Isaac is simply the best there is to offer and I strongly recommend his company to others. His utmost devotion and honesty continue to amaze me as I work on many construction projects along with him. A great team and true friend.

  • A stress free experience.

    In my experience, JIH Builders get’s it all done. I really felt like I can ‘give him a check and go off to Florida’, it’s really stress free. Isaac takes every job like it’s his own, personally tending to every detail and process. I haven’t met another contractor who compares to his standard of organization and quality. He truly views every project as if it would be his own building and that personal approach is what makes all the difference.

    When it comes to Isaac, you could really rely on his expertise when you hire his team for the job. He makes it his business to go over every detail and that provides peace of mind and stability to customers. I am lucky to have found such an honest and experienced contractor and recommend his work to everyone who seeks the best.
