What We Do

The Full Scope of Our Allentown, NJ 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

We route the full perimeter or targeted sections depending on where moisture is actually entering, based on the inspection.

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

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

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?

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 Allentown, NJ 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.
