About Jamison Basement Waterproofing
Jamison Basement Waterproofing serves homeowners throughout the Philadelphia suburbs, including Oreland, Cheltenham, Abington, Willow Grove, and surrounding Montgomery County communities. With a perfect 5.0-star rating across 1688 client reviews, the company has built its reputation on transforming troubled basements into dry, usable spaces. Their service palette spans interior and exterior drainage systems, sump pump installation with battery backup, crawl space encapsulation, dehumidification, foundation wall crack repair, and mold remediation. Every service runs from 7 AM to 9 PM, seven days a week, giving residents flexibility to schedule consultations without disrupting workday obligations.
What distinguishes Jamison from generic waterproofing contractors is their portfolio of proprietary drainage solutions. The GrateDrain interior channel system, GrateTrench entryway drainage, and GrateSump pump system represent branded technologies they install and service. Beyond water management, they handle basement window installation including egress windows, foundation repair with wall crack stabilization, and full crawl space encapsulation with vapor barrier installation. Their mold prevention division addresses both existing contamination and the environmental conditions that foster spore growth, offering homeowners a continuum from diagnosis through remediation.
Customer narratives consistently praise the crews who execute these transformations. For one reviewer with a 1927 colonial, a team completed French drain installation, sump pump placement, full basement waterproofing, and crawl space encapsulation within two days, converting what they described as a terrifying basement into a space where the homeowner now feels comfortable. Another client specifically noted technicians John and Kevin arriving at 7:45 AM to install block windows and update window wells, completing meticulous prep work, executing the installation, and leaving the workspace cleaner than before they began.
What Customers Say
All twelve reviewers awarded five stars, with multiple clients specifically naming crew members John and Kevin for their technical precision and professional conduct. Customers frequently mention project completion speed, with one noting a full basement transformation finished within two days on a nearly century-old structure.
