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

Every sump pump installation is completed by a licensed, insured technician, with electrical work handled to code.

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.

Flat-Rate Pump & Basin Pricing

Battery backup add-ons are priced separately and clearly, so you can decide what fits your budget.

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

We install submersible pumps rated for continuous duty, not the lighter-duty units sold for occasional use.

Sump Pump

Battery Backup Sump Systems

A battery backup pump kicks in automatically if the power goes out during a storm — exactly when you need it most.

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

We also inspect discharge line routing to make sure water is actually getting away from the foundation, not just to the yard next to it.

Sump Pump

Sump Basin Replacement & Resizing

Basin lids are sealed to reduce basement humidity and keep debris out of the pump mechanism.

FAQ

Sump Pump Installation Questions We Hear Every Week

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

We measure inflow during inspection and recommend a pump rated in gallons per hour to match it.

Do I need a battery backup sump pump?▼

If you've had a power outage during a storm before, or your basement has flooded from pump failure, a backup system is worth the investment.

How often should a sump pump be replaced?▼

Most sump pumps last five to ten years depending on usage and water table conditions in your specific Charleston, SC area.

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.
