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.

1

Licensed Drainage Installers

We're licensed and insured for residential and light commercial interior drainage work across Beaverton, OR.

2

Fast Local Scheduling

Interior drainage installs are scheduled locally, without routing through a national call center that adds weeks to the timeline.

3

Flat-Rate Linear-Foot Pricing

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

4

Slope-Verified Installation

Drain tile that isn't sloped correctly simply won't move water — we verify slope with a level during installation, not just by eye.

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

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

FAQ

Interior Drainage System Questions We Hear Every Week

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?▼

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

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?▼

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