Why Choose Us

Why Charleston, SC Property Owners Choose SGP Waterproofing for Sump Pump Installation

An oversized or undersized sump pump both cause problems down the line — short-cycling, premature motor failure, or simply not keeping up during a real storm. We calculate GPH capacity against your basin's actual inflow rather than reaching for a default size.

1

Licensed Installation Crews

We check discharge line routing and check valve placement as part of every install, not just the pump itself.

2

Same-Day Emergency Replacement

We carry common pump models on the truck so a failed unit can often be replaced the same day you call.

3

Flat-Rate Pump & Basin Pricing

Pricing covers the pump, basin, check valve, and discharge line as one quoted number, not itemized surprises after the fact.

4

GPH-Rated Sizing, Not Guesswork

Oversized or undersized pumps both cause problems — sizing it correctly the first time avoids premature failure.

What We Do

What Our Sump Pump Installation Service Actually Covers

Every Charleston, SC Sump Pump Installation job starts with an inspection, not a generic package — here's what that typically includes.

Sump Pump

Primary Sump Pump Installation

A correctly sized primary pump is the backbone of any basement drainage system, and we match horsepower to your basin's actual inflow rate.

Sump Pump

Battery Backup Sump Systems

We size backup battery capacity to your typical outage duration, not just a default runtime estimate.

Sump Pump

Water-Powered Backup Pumps

This option works well as a second layer of protection alongside a battery backup system.

Sump Pump

Check Valve & Discharge Line Repair

A missing or failed check valve lets pumped water flow back into the basin, making your pump work twice as hard for the same result.

Sump Pump

Sump Basin Replacement & Resizing

An undersized basin cycles the pump too frequently, shortening its lifespan — we resize basins when the existing one isn't keeping up.

FAQ

Frequently Asked Questions About Sump Pump Installation

How do I know if my sump pump is too small?▼

If the pump runs constantly or your basin overflows during heavy rain, it's likely undersized for your actual inflow rate.

Do I need a battery backup sump pump?▼

We can walk through battery versus water-powered backup options based on your home's setup.

How often should a sump pump be replaced?▼

We can test an existing pump's condition during an inspection rather than assuming it needs replacement.

Can you install a sump pump the same day it fails?▼

If a specialty basin or pump size is needed, we'll give you a realistic timeline upfront.

What's the difference between primary and backup sump pumps?▼

A primary pump runs on household power and handles day-to-day drainage; a backup pump activates during a power outage or primary pump failure.

Do you offer a warranty on sump pump installation?▼

Yes, every installation comes with a written warranty on both the pump and the installation labor.
