Keep Your Philly Basement Dry, Safe & Mold-Free
From South Philly rowhomes to Northeast duplexes, Philadelphia basements deal with unique challenges—tight spaces, older brick and stone foundations, and city drainage systems that can quickly back up in heavy rain. That’s why our custom waterproofing systems are designed specifically to work in urban homes where space is limited and water problems can escalate fast.
At Basement Waterproofing Specialists, every installation is completed by our in-house crew, never subcontractors. All systems come with a lifetime transferable warranty and right now, Philadelphia homeowners get a free inspection + 17% off when booked this month.
