The South Hills is one of Pittsburgh’s most established residential corridors, stretching from Brookline and Beechview all the way out through Baldwin, Brentwood, and Mt. Lebanon. It’s a region defined by rolling ridges, deeply cut valleys, and neighborhoods built in waves from the early 1900s through the postwar boom. Those older homes — many of them stone or concrete-block construction — were not built with today’s understanding of water management, and they show it.
Hydrostatic pressure is the primary culprit throughout the South Hills. When Pittsburgh gets a heavy rain — and it gets roughly 38 inches per year — water saturates the area’s signature clay-heavy soil and has nowhere to go fast. Instead, it builds up against foundation walls, works through every crack and joint, and finds its way into your basement. Hillside lots make this even more acute: homes positioned on slopes or at the base of a grade are constantly managing water that’s running downhill toward them.
Neighborhoods like Brookline, Carrick, and Overbrook were heavily developed between 1910 and 1940. Homes in these areas often have rubble-stone or block foundations with decades of settlement cracks. Further out in communities like Mt. Lebanon and Bethel Park, postwar construction dominates — and while those homes tend to have poured concrete foundations, the basements were often finished without proper drainage, leaving them vulnerable when the soil around them stays saturated for days after a storm.
South Hills terrain works against you. The ridgeline running from Mt. Washington through Castle Shannon and Scott Township funnels a tremendous amount of groundwater down into neighborhoods below. If your home sits at the base of a hillside, on a cut lot, or near a drainage swale, you’re dealing with elevated hydrostatic pressure year-round — not just during heavy rain events.
Signs You Need Basement Waterproofing

Frequently Asked Questions — South Hills
My South Hills home was built in the 1920s — can an older stone foundation be waterproofed?
Yes. Stone and rubble foundations are among the most common we work on in the South Hills. Interior drain tile systems are especially well-suited for these foundations because they manage water infiltration without requiring full excavation. We can also apply hydraulic cement to major gaps and cracks in the masonry as part of the treatment.
My house is on a hillside lot in South Hills. Is exterior waterproofing worth it?
For homes experiencing significant hydrostatic pressure from an uphill grade, exterior waterproofing can provide a more permanent solution. It stops water at the wall rather than managing it after it enters. We’ll assess whether your situation warrants the investment — for many hillside homes, a combination of interior drainage and surface grading corrections delivers excellent results at a lower cost.
How often does a waterproofed basement need maintenance?
Interior systems require minimal maintenance — mainly annual sump pump testing and keeping the discharge line clear. We recommend checking your system after the first few major storms following installation and annually thereafter. We’re available if anything needs attention.
Do you serve all South Hills communities?
Yes. We serve all South Hills neighborhoods and municipalities including Brookline, Beechview, Carrick, Overbrook, Mt. Oliver, Brentwood, Baldwin, Mt. Lebanon, Bethel Park, Upper St. Clair, Scott Township, Castle Shannon, Dormont, and surrounding areas.
