Job Stories From Mount Pleasant, PA
Solid Ground Restored in Mount Pleasant, PA

In the quaint community of Mount Pleasant, PA, a homeowner faced the distress of foundation instability, a situation that clouded their sense of security and peace in their beloved home. Upon realizing the symptoms—cracks in the walls and doors that stubbornly refused to close—a swift call was made to Keystone Basement Systems to seek trustworthy assistance. Our journey with this homeowner began when our dedicated Customer Care Specialist attentively scheduled an inspection. Our System Design Specialist arrived, calmly evaluating the foundation’s condition with an expert eye. It was clear that underlying soil issues were causing the foundational shifting. With thoughtful precision, we recommended our proven Push Pier System to permanently fortify their home’s foundation. The installation day was met with meticulous preparation, led by a seasoned foreman and our experienced crew. Carefully coordinating each movement, the team hydraulically installed durable steel piers into the solid ground below the unstable layers. Through purposeful, steady action, the foundation was not only stabilized but, in alignment with careful evaluation, lifted towards its original position. Seeing the relief on the homeowner’s face was our greatest reward. The stability restored was akin to welcoming peace back into their daily routine. Now free from the anxiety that once loomed over their home, they shared with us a profound appreciation, one echoed in our belief that even small acts done with intent create meaningful change. Our mission to redefine the contractor experience was mirrored in every step of this project—highlighting how Keystone Basement Systems remains committed to ensuring every home reflects the solid ground upon which it stands. Through expert craftsmanship, transparent communication, and a genuine connection, we transform more than just structures; we bolster lives, one foundation at a time.

70 Year old home in Mount Pleasant

This homeowner called upon Keystone Basement Systems to help her with her 70 year old home that was now getting water up through the basement floor. Keystone sent out one of their best filed inspectors to sit with them and discuss the issue before conducting his very detailed inspection of the problem area. The field inspector knew how urgent this matter was to the homeowner after speaking with her, so he jumped right to work taking all the right very accurate measurements and conducting all the exact test that needed to be done. Once he was completed with his inspection and then returned upstairs to speak with the homeowners once again to go over everything. He explained that the plan to get this house dry again was to install a single sump pump and a 32 foot  internal french drain system that would have one cleanout.
