The Keystone Promise
Frank Kessler founded Keystone in 1984 because he was tired of watching neighbors get burned by contractors who blew into town after a storm and vanished just as quickly. He built this company the same way he spent thirty years building arches in Lancaster County, placing one center stone to lock the others in place. We call our guarantee The Keystone Standard. Every job we perform carries a written 90-day workmanship promise. If you find that something we did isn’t right, you make one phone call. That call brings us back to make it right. No claim forms. No debate. Just a real person, in a truck, at your door.
What the Promise Means for You
When you hire a Keystone company, you are not just buying a service. You are buying the peace of mind that comes from a company that has been doing things the right way since 1984. We make these commitments on every job:
- Upfront pricing: We provide a clear, written estimate before we start. You will know exactly what the job costs, with no surprises on the final bill. We believe in a square deal.
- Trained journeymen: We do not send apprentices to handle complex repairs alone. We send trained journeymen who understand the materials, the codes, and the specific needs of older homes in our community.
- Respect for your home: We work in your house the way we would work in our mother’s home. We leave the job site clean, we respect your property, and we treat your family with courtesy.
- The 90-day workmanship promise: If the work we performed fails or doesn’t meet the standard within 90 days, we return to fix it at no cost to you. We stand behind our labor because we intend to be in this neighborhood for the next thirty years.
- Accountability: When you call us, a person answers the phone. We do not use automated systems to hide from our customers. If you have a concern, you speak to a member of our team who can actually help.
One Standard, Every Brand
The name Keystone is our org chart. In architecture, a keystone is the wedge-shaped stone at the crown of an arch. It bears no weight alone, but it locks every other stone in place. That is how we operate. Whether you are calling us for a plumbing issue, a roof repair, or HVAC maintenance, you are getting the same level of care. Because every brand in our family answers to the same standard, you get the same experience no matter which trade you hire.
We hold ourselves to the K.E.Y.S. values code: Krafted right, Every time, Your home first, and Standing behind it. We believe that a company should be a pillar of its community. Our teams sponsor local events, hire from within the county, and train the next generation of tradespeople. We are not interested in quick, high-pressure sales. We are interested in building relationships that last for decades. When you hire Keystone, you are hiring a neighbor who is committed to keeping their word.
