About
Hi, I’m Thomas Williams — founder of Cornerstone Service Company. I started this business with one mission in mind: to provide honest, affordable solutions for middle-class families, without compromising on quality, reliability, or care.
Problem solving has been a part of my life since I was a teenager. I still remember when I was 15 and my mom’s septic tank cleanout blew off due to backpressure — that moment sparked a curiosity (and a mess!) that grew into a passion. That was ten years ago. Since then, I’ve gained over three years of hands-on plumbing service experience, along with an additional two years in remodeling and new construction projects.
At Cornerstone Service Company, I believe that your home should be a place of comfort — not stress. Whether it’s a leaking pipe, a bathroom renovation, or your dream kitchen taking shape, I’m here to provide trustworthy service with transparency and integrity.
Thank you for visiting, and I look forward to earning your trust.

Thomas was able to come out to our house very quickly. He diagnosed the problem, and fixed multiple issues that we had with the plumbing. I highly recommend him!
