Basement Waterproofing in Minneapolis, MN

The usual causes are soil that slopes toward the house, downspouts that empty next to the foundation, gutters that overflow, leaking foundation cracks and window wells that fill with water. Dampness without visible leaks can also be condensation on cold walls in summer. We check all of these before recommending work.

Interior sealing can help with leaking cracks in poured walls and minor seepage. It doesn't stop water pressure outside the wall, so heavier leaks are better handled with drainage fixes outside and, where needed, exterior foundation waterproofing.

Not always. Regrading and extending downspouts solve many leaking basements on their own. Exterior waterproofing makes sense when water comes through the walls even with good drainage, or when the foundation is already exposed for another project.

When a basement needs an interior drain tile system or a new sump, we coordinate that work with qualified specialists and handle the related construction, such as restoring floors and walls afterward.

Stop the water if you can, shut off power to the wet area if it's safe to do so, and photograph the damage for your insurer. Wet drywall, insulation and carpet need to come out quickly. See our water damage restoration page for the cleanup and rebuild.

Usually not for the waterproofing itself. Most homeowners policies treat seepage and slow leaks as maintenance, while a sudden event such as a burst pipe may be covered, and flood coverage is often a separate policy. Your policy and adjuster decide. We don't negotiate claims or act as a public adjuster; we document the damage and do the repair work.

The one that matches the cause. Water from roof runoff and poor grading is fixed outside with gutters, downspout extensions and regrading. Water coming through a crack is fixed by repairing the crack. Water pushing through the walls or up through the floor needs foundation waterproofing or a drainage system, which we coordinate with specialists. We find the cause before recommending anything.

Most basements can be made dry enough to finish or use for storage. Older block and stone foundations in Twin Cities homes take more work than poured concrete walls, and some need a combination of outside drainage, crack repair and interior measures. We tell you what is realistic after the inspection.
