Interior drainage, exterior grading, crack injection, or a combination — we scope what your McMinnville, 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.
A wet basement is often caused by more than one contributing factor, and we address the combination, not just the obvious symptom.
Wet basement calls get scheduled quickly, especially when there's active water or a musty odor that's gotten worse recently.
We break down each component of the fix so you understand what you're paying for and why it's included.
That range means the diagnosis drives the fix, not which single service a narrower contractor happens to offer.

Every McMinnville, 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.
When groundwater is the primary source, interior drain tile tied to a properly sized sump basin intercepts it before it reaches your floor.
Cracks are often a secondary contributor alongside grading or drainage issues, not the sole cause.
We correct grading and extend downspouts as part of the full repair scope where the inspection points that direction.
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.
We don't stop at the first obvious cause — chronic wet basements often have more than one contributing factor.
You'll get a written scope covering every component of the recommended fix, whether that's one service or several combined.
We're available to reassess if conditions change after a major storm, since McMinnville, OR weather can be unpredictable.

Previous repairs may have addressed only one contributing factor while others were left unresolved — our diagnostic process checks for the full picture.
A written diagnostic summary explains our findings before we recommend any specific repair.
Addressing only one factor while ignoring the others is a common reason prior repairs fail.
We focus on moisture control, and we coordinate with mold remediation specialists for visible growth, which falls outside our direct scope.
Cost depends entirely on which combination of repairs your basement needs — we won't estimate a number until the diagnostic inspection is complete.
Timeline depends on scope — a single-cause fix might take a day, while a combination of drainage, grading, and crack repair can take several days.
