A Strong Foundation With Mt Lebanon Foundation Repair

Because we never take shortcuts on quality, we begin every single project with a meticulous 68-point foundation diagnostic. This detailed examination of your basement will ensure that your foundation is ready for waterproofing and finishing.

We offer many Mt Lebanon foundation repair options, ranging from stabilization to piering, leveling, and replacement. We’ll provide a detailed cost estimate and explain the pros and cons of each service—with no sales pressure and no hassle.

Level Floors for a Safer, More Beautiful Home

In many cases, a sagging floor may not require full foundation repair; oftentimes a few key joist repairs will be enough to re-level your floor and keep your home structurally sound. At Keystone Basement Systems, our staff is certified as both Waterproofing Specialists and Structural Repair Specialists, and we can handle any type of Mt Lebanon floor leveling need.
