Sump Pump Services in Mount Pleasant & Charleston, SC
Keep water out of your crawl space and basement when Lowcountry storms hit.
When You Need Us
- A sump pump that runs constantly or short-cycles on and off
- Standing water in the crawl space or basement after heavy rain
- A pump that fails to turn on when the pit fills
- Strange grinding, rattling, or no sound from the pump
- An older pump with no battery backup before hurricane season
- Rising groundwater from Charleston’s high water table
- A musty, damp crawl space feeding mold in our humidity
- No sump system at all in a flood-prone low-lying property
What to Expect
- Assess your flood risk: We evaluate your property’s drainage, water table, and existing setup to recommend the right pump and capacity.
- Test or size the pump: For repairs we test the float, switch, and motor; for new installs we size the pump to your pit and inflow rate.
- Install or repair: We install or service the pump, check valve, and discharge line so water moves away from your home reliably.
- Add battery backup: We strongly recommend a battery backup so the pump keeps running when a storm cuts your power, exactly when you need it most.
- Test under load: We fill the pit and confirm the pump activates, ejects water, and shuts off properly before we leave.
Sump Pumps and Lowcountry Flooding
Few places need a working sump pump more than the Lowcountry, where a high water table, flat terrain, and hurricane-season downpours regularly push water into crawl spaces and basements from James Island to Mount Pleasant. The worst time to discover a dead pump or a missing battery backup is during a storm when the power is already out. We install and service reliable pumps with proper discharge and backup power so your home stays dry when the next system rolls in off the coast. Contact us to get protected before hurricane season across the Charleston area.

Frequently Asked Questions
Do I really need a battery backup sump pump in Charleston?
Strongly, yes. Our worst flooding comes with hurricanes and major storms, which also knock out power, the exact moment a standard pump stops working. A battery backup keeps water moving out of your crawl space when the grid is down, which is when you need it most.
How often should a sump pump be tested or replaced?
Test it before each storm season by pouring water into the pit and confirming it kicks on. Most pumps last around seven to ten years. If yours is older, runs constantly, or makes odd noises, have it checked before hurricane season rather than after a flood.
My crawl space stays damp. Will a sump pump help?
Often it is part of the answer. Charleston’s high water table keeps many crawl spaces damp, which feeds mold in our humidity. We assess drainage and groundwater and recommend the right combination of sump pump, discharge, and moisture control for your home.
Do you install sump pumps in Mount Pleasant and Charleston?
Yes. We install, repair and replace sump pumps and battery backups across Mount Pleasant, Charleston, Daniel Island, James Island, West Ashley and the beach communities. We assess your drainage and water table first so the pump is sized to what your property actually sees during a storm.
My sump pump runs constantly. What is wrong?
A pump that never shuts off usually has a stuck or misadjusted float switch, a failed check valve letting water fall back into the pit, or it is undersized for the amount of groundwater coming in. Around Charleston, a high water table after heavy rain can also keep a properly working pump busy. We test the float, switch, valve and motor and tell you which it is.
Is a failed sump pump an emergency?
During a storm, yes. If the pit is filling and the pump will not run, water will find its way into the crawl space or basement, and in our humidity that damp does not dry out on its own. We offer 24/7 emergency service. Outside of storm season, a dead pump is still worth fixing promptly rather than waiting for the next big rain.
