We size drain tile diameter and slope to your basement's actual perimeter footage and groundwater volume — undersized systems are a common reason DIY and budget installs fail within a few years.
Interior drain tile installation is scheduled within days across Minneapolis, MN, and most residential jobs are completed in 1 to 2 days start to finish.
You'll know the exact scope — partial wall or full perimeter — before you approve anything.
We install schedule 40 perforated PVC drain tile in a properly sized gravel bed, not the thin-wall flexible tubing that's prone to silting and collapse over time.
We diagnose before we quote, so the Interior Drainage System scope you approve is built around your property, not a generic package.
We saw-cut the slab perimeter, excavate to the footing along the affected walls, and install schedule 40 perforated drain tile in a gravel bed — capturing water at the source before it can rise above slab level.
The system routes to a properly sized sump pit with a dual-pump configuration for redundancy on higher-volume installations. That's the calculation most budget drain tile installs skip, and it's usually why they back up.

This keeps cost proportional to the actual scope of your water problem, tying the partial run into your existing or a new sump. We'd rather size it correctly the first time than have you calling about a system that can't keep up.

This addresses both floor-level and lower-wall moisture in a single integrated system rather than two separate fixes. Getting the sizing right up front is what keeps the system ahead of a heavy storm instead of behind it.

We upsize or rebuild the pit as needed so the whole system, not just the pipe, is rated for your actual water volume. We'd rather size it correctly the first time than have you calling about a system that can't keep up.

Freeze-prone runs receive a freeze-guard fitting so winter conditions don't compromise the system. That's the calculation most budget drain tile installs skip, and it's usually why they back up.

Inspections for Minneapolis interior drainage jobs are typically scheduled within days, with installation following shortly after approval.
The technician measures the affected perimeter, checks your existing sump capacity, and quotes a fixed per-foot price for the scope needed.
Once approved, we cut, excavate, install the drain tile and sump tie-in, and finish with a written warranty on the completed system.
"Water showed up at the same spot along the back wall every time it rained hard. Full drain tile installation along that section tied into a new sump — hasn't shown up once since, through several heavy storms.Floor's stayed completely dry since."
"They actually calculated our drainage volume before sizing the sump pit, which the last company that quoted us didn't bother doing. System's kept up with everything so far, including one very heavy spring storm.System's kept up with everything so far."
"Only needed drainage along two walls, not the whole basement, and they quoted it that way instead of upselling a full-perimeter system we didn't need. Fair pricing and the fix has held completely.Exactly the system that section needed."
"Concrete cutting was noisy for about half a day but they used dust containment and cleaned up thoroughly. Drain tile and vapor membrane installed along the wall — floor's stayed dry since.Exactly the system that section needed."
