Why Choose Us

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

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 Charleston, 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

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

Comprehensive Interior Drainage System Solutions in Charleston, 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

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

This option works well as a lower-disruption alternative to full perimeter drain tile in certain Charleston, SC basement layouts.

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.

How It Works

Our Four-Step Interior Drainage System Dispatch Process

01

Call & Water Pattern Description

Tell us where water shows up and under what conditions — heavy rain, snowmelt, or constantly — so we can scope the likely system needed.

02

On-Site Slab & Wall Inspection

We also check existing drainage, if any, to determine whether repair or new installation makes more sense.

03

Written Linear-Foot Quote

We explain why we're recommending full perimeter versus targeted sections based on what the inspection found.

04

Installation & Flow Test

We test the system with water flow before finishing to confirm proper slope and basin performance.

Customer Reviews

Real Interior Drainage System Reviews From Charleston, SC Property Owners

★★★★★

"Water was coming in along one wall every heavy rain. They installed targeted drain tile just on that section instead of charging us for the whole perimeter."

— Charleston Homeowner

★★★★★

"Cove joint had been the source of our leak for years and nobody had addressed it until now."

— Charleston Customer

★★★★★

"They tested the system with a hose before calling it done, which gave us confidence it would actually work in a real storm."

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?▼

Basin size is based on expected water inflow from the drain tile's linear footage and your Charleston, SC 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?▼

We give you a realistic timeline in the written quote based on your specific basement layout.
