When deciding who to call for water in the basement or crawl space, start with a plumber for active leaks. Call a contractor to diagnose unknown sources, and a structural engineer if you suspect foundation issues. A water remediation team removes standing water and cleans and sanitizes affected areas.

Use this pro hiring guide to act quickly and safely, especially when water is pooling or humidity and mold are present.

Benefits of Hiring a Plumber to Remove Water in a Basement or Crawl Space

A plumber is your first call when a leak causes water in a basement or crawl space. They confirm the source, shut off water, and make repairs to stop further damage. Emergency plumbers respond within hours and can stabilize the situation while coordinating next steps with other specialists if needed. Reasons to hire a plumber:

• Rapid emergency response within hours

• Experienced at handling minor and major leaks

• Can shut off water and stop ongoing leaks

• Performs plumbing repairs at the source

• Implements temporary fixes to limit damage

• Replaces damaged or leaking pipes as needed

• Installs or recommends sump pumps for water removal

• Clears sewer line clogs or pumps septic systems

• Refers you to remediation teams or engineers

If you’re dealing with persistent leaks or standing water, you might want to consider a local plumber to ensure the job is done safely and correctly.

Can I Hire a Contractor or Structural Engineer for Removing Water in a Basement or Crawl Space?

Yes. Hire a contractor when the source is unclear, such as stains or damage away from visible plumbing. Contractors identify unknown issues and guide next steps, including drainage or waterproofing needs. Call a structural engineer if you see signs that involve the foundation or structural damage. An engineer evaluates structural integrity, but you still need a plumber to stop plumbing-related leaks and may need a water remediation team to remove standing water and clean and sanitize the area.

How Do Plumbers Remove Water From a Basement or Crawl Space?

Pros follow a clear sequence to stop the problem and remove water:

1. Shut off water to stop active leaks and complete the plumbing repair

2. Pump out standing water with high‑powered equipment

3. Install a sump pump to move water away from the foundation

4. Replace damaged or leaking pipes at fault

5. Pump the septic system or clear sewer clogs causing backups

Other contractors can regrade landscaping, repair foundation cracks, fix downspouts that drain too close to the house, and add basement waterproofing measures.

How Much Does Removing Water From a Basement or Crawl Space Cost?

Pumping out basement water costs $500 to $1,500 and is only the first step. Fixing water damage averages $3,825, and mold remediation runs $10 to $25 per square foot. Drying with fans and dehumidifiers and replacing wet materials add to the total. Emergency plumber services range from $100 to $500, with higher rates on weekends and holidays. Overall costs vary with water volume, damage extent, drying needs, and material replacement.
