What We Do

What Our Interior Drainage System Service Actually Covers

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.

FAQ

Frequently Asked Questions About Interior Drainage System

Do I need drain tile around the entire perimeter?

Not always — if water is only entering along one wall, a targeted section can be enough, which we determine from inspection findings.

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?

Cutting the slab does involve some disruption, but we work in sections and clean up debris as we go.

How long does interior drainage installation take?

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