What Our Clients Say

Hired Keystone to perform moisture testing of an older 22,000 sqft. space. Kristin and her team immediately scheduled, installed, and documented the tests. Completely turnkey, no follow up needed on my behalf. I would highly recommend.

I hired Keystone Moisture Testing Services for a large mall project in Concord, NC. They were quick, responsive and extremely knowledgeable about my moisture testing needs. I would highly recommend Keystone to anyone requiring moisture testing services.
