About Great Lakes Crawlspace Co.

Great Lakes Crawlspace is a family-owned, locally operated business serving homeowners across the Twin Ports and surrounding areas. We specialize in crawlspace and basement work that protects a home’s structure, manages moisture, and improves long-term durability.

Our work focuses on practical solutions — including crawlspace encapsulation, basement waterproofing, insulation, concrete repair, dehumidifier installation, and sump pump installation or replacement. These services address common problems like moisture intrusion, poor drainage, structural stress, and long-term air quality issues that homeowners often experience for too long, and our mission is to clearly identify the root of these issues and provide dependable, long-lasting solutions.

We take a straightforward, honest approach to every project. During each in-home assessment, we look closely at the conditions of the space and talk through options before recommending solutions. No two homes are alike, and we don’t believe in one-size-fits-all fixes.

Our goal is simple: do solid work, communicate clearly, and leave homeowners feeling confident in the condition of their crawlspace or basement for years to come.

Schedule an in-home assessment to discuss your crawlspace or basement needs.
