Why Choose Us

Why Lexington, SC Property Owners Choose SGP Waterproofing for Interior Drainage System

Not every Lexington, SC basement needs full-perimeter drain tile — sometimes a targeted section addressing the actual entry point is the more cost-effective, equally durable fix. We size the scope to what the inspection actually shows.

1

Licensed Drainage Installers

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

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

Sump basin and pump costs are itemized separately so you can see exactly what makes up the total.

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

Comprehensive Interior Drainage System Solutions in Lexington, SC

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

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

What Lexington, SC Customers Ask Us Most 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?▼

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.
