5 Signs You Need a Sump Pump (Or Yours Needs Attention)
July 21, 2026
If your home has a basement or crawl space, a sump pump is one of the least glamorous, most important pieces of equipment you own. It sits quietly until it's needed — and when it's needed, it needs to actually work.
Signs you may need a sump pump installed
- Your basement or crawl space has flooded before, even once
- You're on a low point of the lot, or water visibly pools near the foundation after rain
- You've noticed a musty smell or dampness in the basement that comes and goes with the weather
- A neighbor with a similar foundation has one installed
Signs your existing sump pump is failing
- It's making unusual grinding, rattling, or humming noises
- It runs constantly, even when it hasn't rained
- It never seems to turn on, even during heavy rain
- It's more than 7-10 years old and has never been serviced
- The float switch looks stuck or the pit has visible debris
Why it matters more than it seems
A sump pump failure usually isn't discovered until it's already too late — during or right after a heavy storm, which is exactly when you can't get ahead of it. A working battery backup system matters too, since a power outage during a storm is often when you need the pump most.
We handle sump pump installation and repair, including battery backup options, throughout Greer and the Upstate.

Frequently Asked Questions
- How do I know if my sump pump is failing?
- Warning signs include unusual noises during operation, a pump that runs constantly or not at all, visible rust, or water pooling in the basement or crawl space despite having a pump installed.
- How long do sump pumps typically last?
- Most sump pumps last around 7-10 years with normal use. Age alone is a reason to have one inspected, even if it seems to be working.
- Do I need a battery backup for my sump pump?
- It's worth considering, especially if you've had power outages during heavy storms — a primary pump won't run without power, which is exactly when flooding risk is highest.
