Cornerstone Builders Group

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.

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.

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!

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!
