What We Do

The Full Scope of Our Amherst, WI Interior Drainage System Work

We scope every Interior Drainage System job in person before quoting it, since two properties with the same symptom rarely need the same fix.

Interior Drainage

Perimeter Drain Tile Installation

A channel is cut along the slab edge, perforated pipe is laid with proper slope, and gravel backfill allows water to flow freely into the drain.

Interior Drainage

Sump Basin Tie-In

Every interior drain system needs a sump basin as its endpoint — we size the basin and pump to match the drain tile's expected inflow.

Interior Drainage

Baseboard Drainage Channel Systems

For finished basements where cutting the slab isn't practical, a baseboard channel system captures wall seepage without disturbing existing flooring.

Interior Drainage

Cove Joint Sealing & Drain Tie-In

We treat the cove joint as part of every interior drainage install, not as a separate add-on.

Interior Drainage

Drain Tile Cleaning & Repair

We camera-inspect old systems where accessible to determine whether repair or replacement makes more financial sense.

★★★★★

"Old drain tile from the 1970s had completely silted up. They cleaned what could be saved and replaced the rest."

— Amherst Homeowner

★★★★★

FAQ

Interior Drainage System Questions We Hear Every Week

Do I need drain tile around the entire perimeter?▼

Full perimeter systems make sense when multiple walls show signs of intrusion or as preventive coverage.

What's the difference between drain tile and a baseboard channel system?▼

Drain tile requires cutting the slab; a baseboard channel is a lower-disruption alternative that captures wall seepage without floor demolition.

Can you repair existing drain tile instead of replacing it?▼

{Sometimes — if the pipe itself is intact but clogged with silt, cleaning can restore function without a full re-installation.|We camera-inspect where accessible to make that determination before recommending replacement.}

How is my sump basin sized for the drain system?▼

An undersized basin cycles the pump too often, so we don't cut corners on sizing.

Will installing drain tile disrupt my finished basement?▼

If disruption is a major concern, we can discuss the baseboard channel alternative instead.

How long does interior drainage installation take?▼

We give you a realistic timeline in the written quote based on your specific basement layout.
