We diagnose the actual water source before we quote anything — no guessing, no upsell, just a plan sized to your basement.
We've seen enough Chanhassen, 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 Chanhassen, 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.
We use pin-type moisture meters and a flashlight-and-crowbar inspection to trace water back to its real entry point.
Every Chanhassen, MN Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
The core fix for most Chanhassen, MN basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.
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.
The cove joint where the floor meets the foundation wall is one of the most common Chanhassen, MN leak points, and we seal it as part of every interior system.
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.
We explain the reasoning behind the recommended system so you know exactly what you're paying for and why.
Most residential basement jobs finish in one to three days, and we test the sump pump under load before we leave.
"We'd patched a basement crack twice ourselves before calling. The interior drain tile system actually fixed it instead of just hiding it again."
— Chanhassen Homeowner
"Sump basin was undersized from the last owner's DIY job. They resized it and we haven't had a drop since."
— Chanhassen Customer
"They walked us through exactly why the water was coming in before quoting anything, which no one else had bothered to do."
— Chanhassen Homeowner
"Installed a battery backup sump pump for us right before a big storm season — glad we did it when we did."
— Chanhassen Customer
Cost depends on linear footage, sump basin size, and whether cove joint sealing is included — we won't give a number without an in-person inspection.
Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.

Not always — an isolated, non-leaking crack can sometimes be handled with injection alone.
