Reliable Sump Pump Installation, Repair & Backup Systems for Northern Louisiana Homes

Shreveport receives over 50 inches of rain annually, and Northern Louisiana’s low-lying terrain and clay-heavy soil make basement and crawlspace flooding a persistent threat. Mark Johnson & Sons Plumbing installs, repairs, and maintains sump pump systems designed to keep Shreveport homes dry — even during the heaviest spring downpours and tropical weather events. As part of our comprehensive plumbing services in Shreveport, we deliver professional results backed by decades of experience.

Why Sump Pumps Matter in Shreveport

Northern Louisiana’s climate delivers intense rainfall concentrated during spring and early summer, with secondary peaks during hurricane and tropical storm season in late summer and fall. When heavy rain saturates the expansive clay soil surrounding your foundation, hydrostatic pressure forces groundwater through cracks, joints, and porous concrete into crawlspaces and below-grade areas.

A properly installed sump pump system collects this infiltrating water in a basin and pumps it away from the foundation before it can pool, seep into living spaces, or cause structural damage. Without one — or with a failed unit — a single heavy storm can deposit hundreds of gallons of water beneath your home, leading to mold growth, wood rot, damaged HVAC equipment, and ruined stored belongings.

Shreveport’s proximity to the Red River and its tributaries also means that water table levels fluctuate with seasonal river stages. Homes in lower-lying areas of Caddo Parish may see groundwater intrusion even during moderate rainfall when river levels are elevated.

Our Sump Pump Services

Sump Pump Installation

We install submersible and pedestal sump pumps sized for your home’s specific water management needs. Every installation includes a properly constructed sump basin, check valve, discharge line routed away from the foundation, and electrical connection.

Sump Pump Repair

When your pump fails to activate, runs continuously, cycles on and off rapidly, or makes unusual noise, we diagnose the issue — whether it is a failed float switch, a burned motor, a clogged impeller, or a stuck check valve — and complete the repair.

Battery Backup Sump Pumps

Power outages during storms are exactly when you need your sump pump most. We install battery backup systems that activate automatically when main power is lost, keeping your home protected through extended outages that frequently accompany severe weather in Northern Louisiana.

Water-Powered Backup Pumps

For homes with reliable municipal water pressure, a water-powered backup pump provides unlimited runtime without batteries. These units use your home’s water supply to create suction and operate independently of the electrical system.

Sump Basin Construction & Replacement

A deteriorated or undersized basin reduces pump efficiency and allows sediment to clog the impeller. We construct new basins to the correct depth and diameter for your conditions, with a sealed lid to prevent moisture and radon entry.

Discharge Line Routing

Improper discharge routing is a common cause of sump pump short-cycling and foundation re-saturation. We route discharge lines to appropriate drainage points — at minimum ten feet from the foundation — with freeze-resistant fittings suited to Northern Louisiana winters.

Frequently Asked Questions

How do I know if I need a sump pump?

If you find standing water, moisture stains, or mold in your crawlspace or basement after rain, a sump pump is likely necessary. Homes in low-lying areas, near waterways, or with high water tables are strong candidates even before water intrusion occurs.

What size sump pump do I need for my Shreveport home?

Sizing depends on the volume of water your property manages during heavy rain. A one-third HP pump handles most residential applications, but homes with significant water intrusion or large footprints may require a one-half HP or larger unit. We assess your conditions and recommend accordingly.

How long do sump pumps last?

A quality submersible pump typically lasts seven to ten years with regular maintenance. Pedestal pumps can last longer since the motor sits above the water line. We recommend replacement before failure, especially heading into Louisiana’s storm season.

Do I really need a battery backup sump pump?

In Shreveport, absolutely. Severe thunderstorms, tropical systems, and ice storms all knock out power — often at the exact time your primary pump is working hardest. A battery backup provides critical protection during these outages.

What maintenance does a sump pump need?

Annual inspection is recommended. We check the float switch operation, test the pump with water, inspect the check valve, clean the basin of debris, verify the discharge line is clear, and test the battery backup if installed.

Can a sump pump handle a major flood event?

A sump pump is designed to manage groundwater infiltration, not surface flooding from a rising river or flash flood. That said, a properly sized system with a backup pump can handle very heavy rainfall infiltration that would overwhelm homes without a pump.

Where does the discharged water go?

We route the discharge line to a drainage point away from your foundation — typically to the yard’s natural drainage path, a storm drain, or a dry well. Louisiana regulations prohibit discharging sump water into the sanitary sewer system.

How much does sump pump installation cost in Shreveport?

Cost varies based on the pump type, basin requirements, discharge routing, and whether a backup system is included. We provide a flat-rate quote after evaluating your crawlspace or basement conditions.

Will a sump pump lower my insurance premiums?

Some insurers offer discounts for homes with active water management systems, including sump pumps with battery backups. Check with your carrier — we can provide installation documentation for your records.

Do you service sump pumps you did not install?

Yes. We repair and maintain all major sump pump brands regardless of who performed the original installation.
