Interior drainage, exterior grading, crack injection, or a combination — we scope what your Cornelius, OR basement actually needs.
Chronic wet basements are rarely caused by just one thing, which is exactly why single-service contractors so often leave the problem half-solved. Our diagnostic process checks grading, drainage, and crack condition together before recommending a fix.
We check walls, floor, grading, gutters, and window wells before recommending a repair, not just the spot where you noticed water.
Wet basement calls get scheduled quickly, especially when there's active water or a musty odor that's gotten worse recently.
Whatever combination of repairs your basement needs, the price is quoted in writing before any work begins.
That range means the diagnosis drives the fix, not which single service a narrower contractor happens to offer.
Every Cornelius, OR Wet Basement Repair job starts with an inspection, not a generic package — here's what that typically includes.
A written diagnostic summary explains what we found and why we're recommending a specific repair combination.
This is the most common fix for Cornelius, OR basements with a consistently high water table.
Active wall cracks get epoxy or polyurethane injection as part of a comprehensive wet basement repair, sealed and classified before we move to other work.

Chronic basement moisture creates conditions for mold growth, and part of our repair scope is getting humidity down to a level that doesn't support it.
We ask how long the basement has been wet, whether it's constant or storm-related, and what you've already tried.
A technician checks interior walls and floor, exterior grading, gutters, and window wells to build a complete picture of what's driving the moisture.
We explain the reasoning behind each recommendation so the plan makes sense, not just a list of line items.
We're available to reassess if conditions change after a major storm, since Cornelius, OR weather can be unpredictable.
