Interior drain tile, sump basins, and vapor barrier wall systems installed by technicians who've done this hundreds of times in Grant, MN basements.
We've seen enough Grant, MN 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 Grant, MN.
Most inspection requests get a same-day or next-day appointment, not a two-week wait.
You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.
Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.
We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.
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.
We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.
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.
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.
