Our staff is a team of hardworking and experienced individuals. Our project mangers, on average, have over twenty years of experience in the construction industry in addition to President John Gilbert Jr.’s forty years of experience. Our project managers are referred to as working foreman. They work hands on with every aspect of each project to ensure flawless quality. This skilled management team allows us to expand our work force at short notice and maintain our superior craftsmanship. Cornerstone has strict standards for our quality and to maintain this we do not subcontract out our construction work.

We perform all of our own concrete forming, steel reinforcement, concrete finishing and truss & roof installation. On top of this our skilled carpenters set windows, hang doors and complete all of the wood trim work on each project. Cornerstone subcontracts out work for electric, plumbing, air-conditioning and other specialty areas. We have a strong rapport with our subcontractors and we have worked along side them for many years.

We work hand in hand with our clients to guarantee that each project is exactly what they are looking for even down to the smallest detail. We believe that great communication is the key to creating your dream home and perfecting every job. Our legacy is built on our standard for quality work. Cornerstone has built the finest custom luxury homes from Ocean Reef to Key West. Our team is passionate about building and we look forward to working with our clients to make their dream home a reality.
