Sump Pumps in Fairfax, VA
90 Years Protecting Northern Virginia Homes. Licensed Master Plumbers on Every Job.
Northern Virginia sits at a geological boundary where groundwater accumulates quickly after heavy rain, and Fairfax County’s clay-heavy soils drain slowly enough to keep hydrostatic pressure pushing against foundation walls long after a storm passes. For homes with basements, a functioning sump pump isn’t optional. It’s the primary line of defense against water intrusion that can damage foundations, flooring, and finished living space.
Since 1936, we’ve helped Northern Virginia homeowners protect their homes through three generations of family ownership. As a Virginia DPOR-licensed contractor with an A+ BBB rating, we handle residential sump pump installation, repair, and replacement across Fairfax County. Our licensed master plumbers are actively involved in diagnostics, not just dispatched technicians running through a checklist. We back every job with a satisfaction guarantee, and we offer free estimates, financing options, and Spanish-speaking support to make scheduling straightforward.

How Sump Pump Systems Work
A sump pump sits in a basin dug at the lowest point of a basement or crawl space. As groundwater rises into the pit through gravel and drainage tile, a float switch triggers the pump, which pushes water out through a discharge line to a dry well, drainage ditch, or storm drain at a safe distance from your foundation.
The system seems straightforward, but several components can fail independently over time. Float switches can stick or malfunction. Check valves, which prevent discharged water from flowing back into the pit, eventually wear out. Discharge lines can freeze in winter or become obstructed. We can inspect all of these components to identify potential failure points before a storm arrives and replace worn parts to keep the system running reliably.
Signs Your Sump Pump Needs Repair
Catching a problem early can mean the difference between a service call and a flooded basement. These are the warning signs our technicians see most often on sump pump repair calls in Fairfax County.
- Pump won’t turn on or runs constantly: A pump that never activates or one that won’t stop running is signaling a mechanical or electrical problem that warrants a professional look.
- Unusual grinding or rattling noises: These sounds often point to a damaged impeller or debris caught in the pump, both of which reduce the pump’s ability to move water.
- Water collecting around the sump pit: Standing water near the basin between rain events, or a pump that activates without rainfall, can indicate a malfunctioning float switch.
- Battery backup fails to respond: A backup system that doesn’t activate during a test is a gap in your protection, not a minor inconvenience.
- Rust or corrosion on the pump body: Iron bacteria or age-related deterioration affects performance and often signals the unit is approaching the end of its reliable service life.
- Pump age: Submersible sump pumps typically last seven to ten years, while pedestal models can last considerably longer. A pump nearing or past that range and showing repeated issues is usually a stronger candidate for replacement than another round of repair.
If you’re seeing any of these signs, don’t wait for the next heavy rain to find out how serious the problem is. Our team can diagnose the issue and walk you through your options.

Battery Backup & Secondary Pump Systems for Fairfax Homes
A sump pump’s most demanding moment is almost always during a heavy storm, precisely when power outages are most likely. A primary pump running on household current provides no protection the moment the power goes out. Battery backup systems use a deep-cycle battery maintained by a trickle charger, allowing them to operate independently and activate automatically if the primary pump fails or is overwhelmed.
For homes in Fairfax County with finished basements, the math is straightforward. Installing a battery backup system typically costs a fraction of what a single water damage insurance claim may run. At Long's Corporation, we can assess whether your current sump pump setup provides adequate protection and help you address any gaps. If adding a secondary pump or backup system makes sense for your home, we’ll evaluate your setup and walk you through your options.
