The Cornerstone Company was founded in 2003 on a vision of becoming the preferred design-build contractor for commercial and light industrial buildings in the Charleston market. Our original slogan was and remains "Building to Make a Difference". Since that time we have successfully completed hundreds of projects ranging from small retail and medical upfits to large multi-tenant commercial, office, self-storage and warehouse buildings.
Historically, master builders were responsible for both the design and construction of most temples, cathedrals, monuments and large public buildings. Over time the architectural design and engineering responsibilities separated from the construction responsibilities and project owners were often left with a fractured traditional bid process that undercuts teamwork and trust, rewards low unqualified bidders and leaves the owners in an unfortunate mediation role.Ultimately, time, money and quality are often compromised with the traditional bid process.
Steinberg Law Firm has named The Cornerstone Company as their general contractor for their new 14,000 SF office building in Goose Creek. The building will be located next to Infinger Furniture on Hwy 52. Construction is scheduled to start in the fall of 2022. The Cornerstone Company recently started clearing a site at the entrance to The Ponds community in Summerville for a new building for Ashley Pines Animal Hospital. The building also features an additional 4,100 SF for dental, medical, or office tenants.

My husband and I worked with Jason J from Cornerstone and he was factastic. We could not have asked for a more professional, efficient and fast install from another company. From start to finish everyone from Jason to to the roofers were exceptional. Even our insurance adjuster was happy that we used Cornerstone. If you want quality work with a great team use Cornerstone Construction.

I cannot say enough good things about Cornerstone! Building a new dental office is a huge undertaking due to the amount of plumbing, electrical and coordination between all the moving parts in a tight space. I was advised to not go the design-build route at the beginning of this project, but I truly wish I had just let Cornerstone quarterback this from the start and pick their own architect/engineer.

They have proven again and again that they only have my best interest at heart. They came in exactly at my budget and were very cognizant of it throughout the entire process. Terry runs an honest, transparent, caring and detail-focused company that's committed to high quality and ensuring the client is happy. They are everything you could want in a GC and more, which I believe is pretty rare to say about a contractor at the end of a project. Ben, Tyler and Christian are all excellent in their respective positions and were there for me every step of the way. I will forever be grateful to them! If you have any type of commercial project, this team is the way to go!

We could not be happier with the work that Cornerstone Company did for our new chiropractic office. Terry met with us several times through the planning process, his team was always professional and attended to every request we had. They walked us through the entire process to make sure we knew how each step would go. Our project was done on time and under budget and we owe it all to Terry, Christian and the rest of the Cornerstone Company. Well trust them with all of our future projects!
