Sterner Waterproofing & Excavating

Sterner Waterproofing and Excavating operates in Olmsted Township, Ohio, as a specialized excavating contractor focused on water management solutions for residential properties. The company holds a 4.8-star rating drawn from 49 customer reviews, reflecting consistent service quality in basement waterproofing, drainage systems, and sewer line work. Their service area includes Olmsted Township and surrounding communities in the Cleveland metropolitan region. The business operates seven days a week from 7 AM to 7 PM, providing flexible scheduling for homeowners dealing with water intrusion emergencies.

What distinguishes Sterner is their diagnostic-first approach to water problems. Rather than recommending invasive and costly repairs, their team identifies the exact source of water intrusion before proposing solutions. The company handles complete sewer line replacements, transitioning homes from outdated clay pipes to modern PVC systems, and they also pour new basement floors following drainage installations. Their website emphasizes fixing problems right the first time, which they attribute to thorough initial assessment rather than reactive repairs.

Reviewers consistently highlight specific team members who handled their projects. One homeowner described Mathias diagnosing a cracked footer drain with root intrusion that other contractors missed, resulting in a targeted repair rather than the extensive and expensive work proposed by others. The same reviewer noted Noah's thorough cleanup of debris after the excavation. Another customer recounted calling Mathias for an emergency excavation when a power line was severed, describing his prompt arrival and coordination with an electrician to restore power quickly. Office staff member Mary receives mentions for keeping clients informed about scheduling timelines.
