I am thrilled to share my positive experience working with Jack and JB General Contractors on my Beverly Hills Flagship Store. First and foremost, I must emphasize how incredibly pleased I am by the quality of the craftsmanship. What Jack promises, he delivers. He and his team were an absolute delight to work with. The entire team was extremely professional, dependable, and strong communicators. I would certainly hire JB General Contractors again and would highly recommend them to others.

We have worked with JB General Contractors on retrofit work dealing with our 3-story, multi-family properties that have tuck-under parking. Their work is exceptional and the professionalism has been 5 star, which is needed when you are dealing with customers that live onsite. We appreciate their communication and follow-through in getting the work done according to the plans. We will continue to use them in the future.

Thank you for the outstanding work on our retrofit it couldn’t have gone smoother! Can’t believe it only took you two weeks with zero issues or change orders. You were professional, responsive and communicative every step of the way. If you need any referrals feel free to send them my way.

Jack and JB Contractors were an absolute flawless team to work with. They finished the project early, on budget, and with absolute ease. Their professionalism was paramount and they delivered on all promises. I literally handed them the project and did not hear anything until completion of the project (exactly what I wanted). Will definitely be using them for all future projects with my eyes closed!

Our retrofit at 11813 Iowa Ave, W. L.A., CA 90025, contracted with JB General Contractors is near completion.  As Managing Partner and spokesman for our LLC members, I wanted to thank you for recommending Jack Benisty as one of the contractors to consider for the project.   He was professional, involved, available, knowledgeable, competitive and kept to his forecasted schedule.  He and his company were a pleasure to work with.   He can use us as a reference if our experience can be of help to another building owner.

Twenty years ago, we awarded our first job to JB General Contractors. Since then, Jack Benisty has been our first choice for our construction projects. He has done multiple projects for us including, large tenant improvement, seismic retrofit and a major rooftop construction with a pool. JB General Contractors always delivers a perfect job and in a timely manner. I highly recommend their services.

I love recommending Jack to clients for their work because at the end of every project, they are happy and satisfied. That is hard to do in today’s world. Jack made our lives, as part of a design team, easier during construction, as well. He is always proactive and looking for solutions to get the job done. I wish more contractors operated the way Jack does.

I have worked with Jack on a couple of projects. As a general contractor, he has always kept the high quality of work in his projects. His daily communication and close coordination made the job much easier for me as part of the design team and had ensured the project success, quality and aesthetics. He is also very thorough in his job and makes sure all the details are worked out properly. I will definitely recommend him to any client as a general contractor.
