About Cornerstone Construction Masonry plus+
Based in Theresa, NY, we are dedicated to honest craftsmanship, thorough attention to detail, and building projects that stand the test of time throughout Jefferson County and beyond.
Craftsmanship built on patience and care
While there are many contractors across Northern New York, we set ourselves apart through uncompromising quality. We believe that true craftsmanship takes patience. We never rush through a job just to check it off the list; instead, we invest the time and precision required to ensure every brick, stone, and joint is set to perfection.
From the ground up to intricate stone work
Our expertise spans complete building solutions. Whether framing a new custom home from the foundation up, constructing an authentic fieldstone fireplace, or handling smaller residential repairs, every project receives the exact same meticulous standard of excellence. No project is too complex or too small when quality is the goal.
Putting our clients first
Above all, we value our clients and the trust they place in us. There is nothing more rewarding than seeing a homeowner's genuine satisfaction when they see the finished result. We take pride in building strong, lasting relationships across Theresa and surrounding communities through open communication and dependable results.
