Interior drain tile, sump basins, and vapor barrier wall systems installed by technicians who've done this hundreds of times in Pullman, WA basements.
We've seen enough Pullman, WA basements to know that a wet spot in one corner rarely tells the whole story. Before we recommend drain tile or a sump upgrade, we trace the water back to where it's actually entering, not just where you noticed it.
We're bonded and insured for both residential and light commercial basement work across Pullman, WA.
Our Pullman, WA crews are staffed locally, so a wet basement call doesn't sit in a national queue for a week.
You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.
We use pin-type moisture meters and a flashlight-and-crowbar inspection to trace water back to its real entry point.
Every Pullman, WA Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.
Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.
Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.
We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.
Poor window well drainage is one of the most overlooked Pullman, WA basement leak sources, and it's often the cheapest fix on the list.
A quick phone conversation lets us bring the right equipment on the first visit instead of a second trip.
A technician walks the basement with a moisture meter, checking walls, floor, and cove joints to trace the water back to its actual source.
We explain the reasoning behind the recommended system so you know exactly what you're paying for and why.
You'll get warranty paperwork and a walkthrough of how the system works so you know what to expect going forward.

Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.
Larger basements or those needing extensive crack repair can take a bit longer — we'll give you a realistic timeline in the written quote.
