All reviews for Cornerstone Builders Group

Very good

My husband and I worked with Cornerstone Builders Group to build our family home just completed in February and I must say it is absolutely our dream house! Seeing as we went from living in an apartment in Hoboken to a 4500 sq foot home, it is a dream come true.

This company is detail oriented, proactively communicates, and does fantastic work. I've used them for two larger projects for my Healthcare company and I have been extremely satisfied.

If you want a contractor who will listen, collaborate and ultimately deliver amazing results, go with Cornerstone. Leo, Frank, Al and the entire team are amazing. Highly highly recommend!

I recently had Cornerstone manage and construct the expansion of my dental office. From start to finish they were a pleasure to work with. The team was attentive to the fact that I could not close my business during the renovations and they exceeded all of my expectations. I plan on using them for my home renovation as well. They were very professional and expeditious. Highly recommend this team for your construction needs.

Two months into lockdown, I looked at my husband and said, I need a new kitchen, or we’re moving. Enter Cornerstone Builders Group and the decision was easy. We stayed where we were, but made our house into our dream home. Leo, Frank, Al and the entire CBG team made everything easy. Their budgeting process shows you where every dime goes and is so detailed there were never surprise charges. There was constant communication, they are true professionals, their quality is superb and we are beyond thrilled with our end result. Cornerstone will forever have our highest recommendation.

I can only speak highly of Cornerstone's work. I have worked with them as the architect or project designer on various projects for many years and their product always come out beautiful. Besides their quality, they have a great team that works vigorously to complete projects on time and with a smooth process. They have a great team on site and in the office and their transparency is always appreciated. On every project I have worked with them on, they keep their client happy and that always speaks volumes. 10/10 would recommend.

Where to start! From the moment we first met with Leo and Frank in their office to working daily with Mike and the rest of the Cornerstone team we couldn't have been more pleased. They are beyond professional, trustworthy, knowledgeable and simply experts in their field. Having never built a home, my husband and I had no idea what to expect. They walked us through the entire process, communication was exceptional, answered all of our questions and were a pleasure to work with. We trusted them with building our Dream Home and they exceeded our expectations. Cornerstone has our highest recommendation- would work with them again in a heartbeat!!!

Cornerstone Builders did an outstanding job bringing our vision for a state-of-the-art wellness center in Mahwah, NJ, to life. This was no ordinary project—it was about creating a sanctuary where luxury and wellness intersect, and the Cornerstone team truly exceeded our expectations. Together we managed every aspect, from construction planning to the final touches on unique amenities like our red-light sauna, cold plunge, and high-tech bio circuit.

The facility is built to inspire, and thanks to Cornerstone’s attention to detail, every element seamlessly integrates, from the Pilates and semi-private training areas to the full-court basketball setup and golf simulator. Their expertise and commitment to quality craftsmanship are evident throughout. The result is a wellness center that is as functional as it is stunning, creating an environment our members.

Cornerstone was first class from start to finish. Leo, Frank, and the team are highly responsive and made the process of building our state-of-the-art office exciting and run smoothly. I felt they were not only invested in the project but invested in myself and the success of my business. I highly recommend Cornerstone Builders Group for your next project!

Working with Cornerstone Builders Group has been a fantastic experience. They led our predevelopment project management for our property on Hope Avenue, and I'm beyond pleased with the results. The Cornerstone team assembled a skilled development team perfectly tailored for our project’s unique needs, managing everything from assembling the right professionals to providing a comprehensive density and proforma analysis for our planned 22-unit building. They oversaw every step leading to site plan approval, ensuring smooth coordination with local authorities and complete transparency in cost management.

Incredibly, all this was accomplished in less than a year, a timeline we hadn’t expected to meet. Their expertise and attention to detail made all the difference, and I couldn’t recommend them more highly!

I have had the pleasure to work with Cornerstone Builders Group on many projects over the past few years. They are always professional, punctual, and bring their knowledge and confidence to every project. I look forward to working with them on many more projects to come!

Cornerstone Builders Group completed a full remodel of a warehouse in Hackensack to create an indoor vertical farm. The communication was seamless, answering all questions quickly and professionally. The work performed was impeccable and adhered to proposed timeline. Frank and Leo are experts in their field, a pleasure to work with and I would gladly hire them for our next project.

Cornerstone recently helped us remodel our Edward Jones office and we couldn’t be happier with the results! The new window really transformed the feel of the space and helped brighten everything up! They were a pleasure to work with throughout the process. They communicated with us every step of the way, and even followed up with us a few times afterwards to make sure we were happy with the end result. I would absolutely recommend their services!

We recently completed a 4-unit mixed-use apartment building in Ridgewood, NJ, with Cornerstone Builders Group as our construction management partner, and I couldn't be happier with the outcome. The Cornerstone team managed every phase of this project with precision and professionalism, ensuring that both the residential and commercial aspects were designed and built to the highest standards.
Their expertise in mixed-use development was evident from start to finish—they handled everything seamlessly, from site preparation to final finishes. The project stayed on track and within budget, even with some challenging permitting requirements unique to Ridgewood. The Cornerstone team's commitment to quality, transparency, and meeting our project goals was outstanding. I would highly recommend them to anyone looking for reliable and skilled construction management!

They don't pay subcontractors.

Worker was going around Home Depot with his mask down under his chin the whole time he was shopping. Totally unacceptable right now.
