We diagnose the actual water source before we quote anything — no guessing, no upsell, just a plan sized to your basement.
Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.
Every technician carries full state licensing and liability coverage before they ever step into your basement.
Most inspection requests get a same-day or next-day appointment, not a two-week wait.
No hourly billing and no change orders once your basement floor is already open.
Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.
Every West Linn, OR Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
The core fix for most West Linn, OR basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.
Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.
Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.
A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.
Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.
A quick phone conversation lets us bring the right equipment on the first visit instead of a second trip.
We also check exterior grading and downspouts, since a lot of basement leaks start outside, not inside.
You'll see drain tile footage, sump specs, and labor broken out separately, not one vague lump-sum number.
Most residential basement jobs finish in one to three days, and we test the sump pump under load before we leave.
