What We Do

What Our Interior Drainage System Service Actually Covers

Every Arlington, WA Interior Drainage System job starts with an inspection, not a generic package — here's what that typically includes.

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

Basin placement is chosen for the shortest, most direct discharge path away from the foundation.

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

The cove joint where wall meets floor is sealed and tied directly into the drain system so water is captured right at the entry point.

Interior Drainage

Drain Tile Cleaning & Repair

Existing drain tile that's clogged with silt or has failed slope can often be cleaned or repaired rather than fully replaced.

FAQ

Frequently Asked Questions About Interior Drainage System

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?

We'll recommend whichever fits your basement's finish level and budget.

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?

Basin size is based on expected water inflow from the drain tile's linear footage and your Arlington, WA area's typical rainfall intensity.

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?

Most residential installs finish in one to three days depending on perimeter length and whether cove joint sealing is included.
