Chris Sodergren founded Clifton Contracting in 1997 as a homebuilder and general contractor, constructing homes, additions, and basement build-outs. Recognizing that groundwater levels in Northern Virginia often sit near or above basement levels, he launched Exterior Waterproofing Experts in 1999 to solve water intrusion issues. The team focuses on preventing water from entering homes through excavation, grading, and the installation of drainage systems. Services include installing sump pump systems, underground plumbing for downspouts, French drains for wet yards, and egress windows with drainage tie-ins to foundation drains.

The company employs various methods to stabilize foundations and repair cracks, including carbon fiber reinforcements, wall anchor systems, and helical push piers. For yard drainage and erosion control, they install swales, perform re-grading, and use landscaping techniques like sod and seed installation to redirect water. The firm provides a warranty structure that includes a lifetime warranty on foundation wall waterproofing, a five-year warranty on hardscapes, and a ten-year warranty on buried drain pipes.

Customers highlight the professionalism and technical expertise of the team, particularly noting the owner’s thorough assessment of drainage issues and structural damage. Reviewers appreciate clear explanations of options, fair pricing compared to other contractors, and the crew’s ability to complete work quickly while leaving the job site clean. The business is recognized for its strong warranty coverage and its ability to resolve complex water and foundation problems in older homes throughout the region.
