Mt. Lebanon is one of Pittsburgh’s most distinguished inner suburbs — developed primarily between the 1920s and 1950s as a streetcar community, and still defined today by its tree-lined streets and architecturally significant homes. Tudor Revival, Colonial Revival, and brick American Foursquare styles dominate the older neighborhoods near the trolley stops on Washington Road and Bower Hill Road. These are beautiful homes, and they command premium prices — but their age means their basement waterproofing systems are often 80 to 100 years old.
Pre-WWII construction in Mt. Lebanon typically means a poured concrete or concrete-block foundation, with original clay tile perimeter drain installed at the footing. That system has been in the ground for a century, and in the Pittsburgh region’s heavy clay soil, it’s long past functional. When those tiles collapse or clog, water that was being directed away from the foundation now sits against it, building hydrostatic pressure that eventually finds every crack and joint. Finished Mt. Lebanon basements — which are extremely common given the home values and owner investment — are especially vulnerable.
Mt. Lebanon’s terrain adds to the challenge. The municipality sits across a series of ridges, and many of the most sought-after streets follow hillside grades with significant uphill properties. Homes on the lower side of these slopes receive not just their own rainfall, but groundwater migrating downhill from neighboring properties. Proper waterproofing for these homes needs to account for lateral water movement, not just vertical infiltration.
Protecting a Mt. Lebanon home means protecting a significant investment. The median home value in Mt. Lebanon is among the highest in Allegheny County. A wet basement isn’t just an inconvenience — it’s a threat to the structural integrity and market value of a home worth $400,000 to $800,000 or more. Waterproofing is routine maintenance, not a luxury.

Frequently Asked Questions — Mt. Lebanon
Can you waterproof a Mt. Lebanon home without disturbing the landscaping?
Interior waterproofing does not require exterior excavation, making it the best choice for homeowners who want to preserve mature landscaping and hardscaping. We work entirely from inside the basement. Exterior work, when needed, is done with care and we discuss site restoration as part of the project planning.
My Mt. Lebanon home has original lathe and plaster walls in the basement — will waterproofing damage them?
Interior drain tile installation requires breaking the concrete floor at the perimeter — typically 12–18 inches wide. Any finished wall framing in that zone may need to be temporarily removed. We work carefully and discuss what’s involved before starting. Many homeowners use the project as an opportunity to update the basement finishes afterward.
Is mold a concern in Mt. Lebanon basements?
Yes. Chronic moisture in older Mt. Lebanon basements creates ideal conditions for mold growth behind drywall, on wood joists, and in insulation. If you have water intrusion, you likely have mold somewhere. We address the moisture source; if visible mold is present, we can refer you to remediation contractors. Waterproofing prevents the recurrence.
Will waterproofing increase my Mt. Lebanon home’s resale value?
Yes. In Mt. Lebanon’s competitive real estate market, a wet basement is a red flag that buyers and inspectors will flag — and it typically costs sellers far more in price reductions or lost deals than the waterproofing work would have cost. A documented, warranted waterproofing system is a positive selling point.
