Why Choose Us

Four Reasons Our Interior Drainage System Clients Don't Call Anyone Else

Drain tile that isn't sloped correctly is one of the most common installation failures we see when repairing someone else's prior work — water simply pools instead of flowing to the basin. We verify slope with a level, not by eye.

2

Fast Local Scheduling

3

Flat-Rate Linear-Foot Pricing

Pricing is based on linear footage of drain tile needed, quoted in writing after an in-person measurement.

What We Do

Comprehensive Interior Drainage System Solutions in Gresham, OR

Every Gresham, OR 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

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?▼

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?▼

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?▼

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