Crawl Space Sump Pump Installation in Charlotte
When water shows up under your house after every heavy rain, a sump pump gets it out fast and automatically.
How a crawl space sump works
A basin is dug at the lowest point of the crawl space. Water flows into it, either on its own or through a French drain. A float switch turns the pump on. The pump pushes the water through a pipe to the yard or a storm drain, well away from the foundation.
In a crawl space, the basin should have a sealed lid so the pump does not pull humid air into the space.
When you need one
A sump pump makes sense if:
- Water pools under the house more than once or twice a year
- Your lot is low or sits near a creek or drainage path
- Grading and downspout fixes did not solve the problem
- You are encapsulating and want a way to handle any future water
Battery backup
Charlotte storms often knock out power right when the pump is needed most. A battery backup pump keeps running for hours without power. For most homes, it is worth the extra few hundred dollars.
What it costs
A crawl space sump pump with a sealed basin usually costs $1,200 to $3,500 installed in Charlotte. Adding a French drain to feed it adds more. Battery backup adds $300 to $800. If water is under the house right now, start with our guide on standing water under your house.
