What to Do After Flooding in Your House: A Guide to Choosing a Water Damage Service

August 8, 2025

by onsitepro.org

Flooding inside your home is one of the most stressful emergencies a property owner can face. Beyond the immediate mess, standing water can destroy flooring, weaken drywall, encourage mold growth, and cause electrical hazards.

In Southern California, where plumbing failures, appliance leaks, and storm surges all pose risks, knowing what to do after flooding is essential. This guide covers immediate safety steps, damage control, cleanup, and how to choose a qualified water damage restoration service.

Immediate Safety Steps After Home Flooding

Before worrying about property loss, your first priority is protecting your household from harm.

Turn Off Electricity and Gas

Water conducts electricity. If water levels are near outlets or appliances, shut off power at the breaker. Gas should also be turned off if flooding reaches gas lines or appliances to prevent leaks and fire hazards.

Avoid Contaminated Water

Floodwater may contain sewage, chemicals, or bacteria. Avoid skin contact, and keep children and pets away from flooded areas. Wear gloves, boots, and protective gear before entering.

Document the Damage

Take photos and videos before moving items or starting cleanup. These records are critical for insurance claims and contractor estimates.

Controlling Damage Before Help Arrives

Quick action can make a major difference in reducing losses.

Remove Standing Water if Safe

For minor flooding, use a wet vacuum, mop, or bucket to extract water. For major flooding, wait for professionals with pumps and specialized equipment.

Protect Furniture and Belongings

Move unaffected items to a dry area. Place aluminum foil or wood blocks under furniture legs to prevent additional water absorption.

Increase Ventilation

Open windows and doors when weather permits. Use fans to improve airflow, but avoid using household HVAC systems until inspected to prevent mold spread.

The Hidden Risks of Delaying Water Damage Cleanup

Many homeowners underestimate how quickly water damage escalates.

Mold Growth Within 24–48 Hours

Moisture creates the perfect environment for mold. Once it begins spreading, remediation costs and health risks multiply.

Structural Weakening

Water softens drywall, warps wood flooring, and damages insulation. Over time, these materials may need full replacement.

Electrical and Fire Hazards

Wiring exposed to water can cause shorts or sparks. Professional inspections are essential before restoring power.

Choosing the Right Water Damage Restoration Service

Not all restoration companies are equal. Selecting the right team ensures safe, effective, and compliant repairs.

Certifications and Standards

Look for companies certified by the IICRC (Institute of Inspection, Cleaning, and Restoration Certification). Certification ensures technicians follow industry best practices.

24/7 Emergency Response

Flooding requires immediate attention. A reliable company offers 24/7 availability and rapid dispatch, usually within 60 minutes in the Los Angeles area.

Comprehensive Services

The best providers handle the full process: water extraction, drying, mold prevention, structural repairs, and insurance documentation.

Insurance Coordination

Experienced companies work directly with insurers, helping streamline claims and reduce out-of-pocket expenses.

Cost of Water Damage Restoration

The price depends on the extent of flooding, property size, and level of damage.

Minor Incidents

Small leaks or appliance overflows typically cost $1,500–$5,000, covering water extraction and drying.

Moderate Damage

Mid-sized floods affecting several rooms may range from $5,000–$15,000, including drywall removal, flooring replacement, and dehumidification.

Severe Flooding

Whole-house flooding or sewage backup can exceed $20,000–$50,000, requiring demolition, mold remediation, and reconstruction.

Does Homeowners Insurance Cover Flooding?

Coverage depends on the cause of the water damage.

Covered Events

Most homeowners’ policies cover water damage from burst pipes, appliance failures, and sudden plumbing leaks.

Exclusions

Flooding from heavy rain, storm surges, or poor maintenance is often excluded. For natural floods, separate flood insurance through FEMA’s NFIP program may be required.

Tips for Filing a Claim

Contact your insurer immediately after flooding
Provide photos, videos, and contractor reports
Keep receipts for temporary housing or repairs

Case Study: Flooding in a Los Angeles Home

A Sherman Oaks family experienced severe flooding when a supply line burst under their kitchen sink.

Over 1,200 sq. ft. affected, including hardwood floors and cabinetry
Water extraction performed within 2 hours of arrival
Drywall and insulation replaced in 3 rooms
Dehumidifiers ran for 5 days to ensure drying

The remediation cost was $14,500, largely covered by insurance. Early response prevented mold growth and preserved most furnishings.

How to Prevent Future Water Damage

Proactive steps reduce the risk of future flooding and lower insurance claims.

Routine Maintenance

Inspect plumbing, roofing, and appliances regularly for wear or leaks.

Install Leak Detection Systems

Smart sensors alert you to leaks before they cause major flooding.

Upgrade Drainage Systems

Ensure gutters, downspouts, and sump pumps are clear and functional, especially before heavy rains.

Partner with Professionals

Schedule annual inspections with a certified water damage company to identify hidden vulnerabilities.

Conclusion

Flooding is a nightmare for homeowners, but acting quickly and choosing the right restoration service makes all the difference.

If you live in Los Angeles or Southern California, where storms, plumbing issues, and aging homes create constant risks, prepare now by knowing who to call. The right water damage restoration team will protect your property, your health, and your peace of mind.
