The First 24 Hours After Water Damage: What Homeowners Need to Know

Water damage is a significant concern for homeowners, with approximately 14,000 individuals in the U.S. experiencing water damage emergencies daily. The first 24 to 48 hours following such incidents are crucial in preventing mold growth and minimizing property damage. 

According to the U.S. Environmental Protection Agency (EPA), drying wet materials within this timeframe is essential to prevent mold growth. Similarly, the Centers for Disease Control and Prevention (CDC) emphasizes the importance of cleaning and drying wet items within 48 to 72 hours to prevent mold growth.

Experiencing water damage in your Philadelphia home can be distressing, but acting swiftly within the first 24 hours can significantly reduce the impact and facilitate a smoother restoration process. Calling in water damage restoration experts in Philadelphia can help prevent further structural damage.

This comprehensive blog outlines the essential steps for homeowners to manage water damage effectively, emphasizing safety, documentation, and prompt action.

Why Water Damage Is a Big Deal in Philadelphia

Philadelphia’s charm lies in its beautiful brownstones, row homes, and historic architecture. But those same structures are often decades (or centuries) old, making them vulnerable to burst pipes, leaking roofs, and outdated drainage systems.

Here’s why homeowners are particularly at risk:

  • Aging Infrastructure: Many homes still rely on plumbing from the 1950s or earlier.
  • Storm-Prone Seasons: Between Nor’easters in winter and torrential downpours in summer, flooding is becoming more common.
  • Flash Flood Zones: Areas near the Schuylkill River and Cobbs Creek are especially prone to rapid flooding during storms.
  • Freezing Winters: Ice dams and frozen pipes can cause leaks overnight.

If you think water damage isn’t a big deal, consider this: Mold can start growing in as little as 24–48 hours. A small leak today could lead to thousands in repair costs tomorrow, and worse, it could jeopardize your family’s health.

Immediate Actions to Take Within the First 24 Hours

Step 1: Ensure Safety – Don’t Rush In

If you come home to a water-logged room or flooded basement, pause before jumping in.

  • Turn off power to the affected areas — water and electricity are a deadly combo.
  • Shut off your main water supply if the damage is due to a burst pipe.
  • Avoid walking through floodwater, especially if it’s brown, gray, or has a foul smell (this could indicate a sewage backup).
  • If the ceilings are sagging, leave the area — it could collapse.

Step 2: Document Everything

Take photos and videos of:

  • Damaged furniture, appliances, flooring, and walls
  • Water lines on the wall
  • Leaking appliances or burst pipes
  • Any mold growth

Make a list of damaged items, their estimated value, and receipts if available.

Philadelphia Tip: If you’re in a historic home, take extra photos. Antique moldings, plaster walls, or hardwood flooring can be harder (and costlier) to replace.

Step 3: Call Your Insurance Provider Immediately

Start the claims process fast.

  • Report the incident with details and media.
  • Ask about coverage for water vs. flood damage (standard homeowner policies usually don’t cover flood).
  • Get clarity on whether you can start mitigation efforts before the adjuster visits (most insurers allow it).

Step 4: Start Water Removal

The goal is to remove standing water ASAP to avoid deeper absorption into materials.

  • Use wet/dry vacs, mops, and buckets to clear water.
  • Elevate furniture if it hasn’t already been soaked.
  • Remove rugs, curtains, or upholstery to dry separately.
  • Start fans, dehumidifiers, or HVAC systems to help dry the space.

Data Point: FEMA reports that just 1 inch of water can cause over $25,000 in damage to your home.

Step 5: Drying and Dehumidification

Once visible water is gone, your next battle is moisture.

  • Use industrial fans and dehumidifiers for 2–3 days straight
  • Open windows if weather permits (in summer or fall)
  • Pull up baseboards to air out behind walls
  • Check inside cabinets, closets, and under the flooring

Moisture = Mold. If you’re not thorough, spores may begin developing behind drywall or subflooring within 24–48 hours.

Step 6: Sanitize and Disinfect

After drying, clean and disinfect all surfaces:

  • Use bleach solutions (or antimicrobial sprays) for hard surfaces
  • Replace or dispose of items that cannot be safely cleaned (like drywall, carpeting, or insulation)

 If the water was from a sewer backup, call a professional — this is considered “Category 3” water and poses major health risks.

Step 7: Professional Assessment

After you’ve stopped the bleeding, it’s time for triage.

  • Hire a certified water damage restoration company to assess long-term issues.
  • They’ll check for:
    • Structural integrity
    • Hidden moisture behind walls
    • Potential mold growth
    • Insulation damage

Pro Tip: Look for companies certified by the IICRC. This ensures they use industry-standard procedures.

Smart Strategies to Prevent Water Damage Before It Starts

Philadelphia homeowners can take several proactive steps to avoid repeat disasters:

  • Inspect your plumbing every year
  • Install a sump pump with a battery backup
  • Clean gutters and downspouts every spring and fall
  • Seal cracks in foundations or around windows
  • Add smart water leak detectors (like Flo or Moen) to alert your phone

Extra Tip: If you live near the Schuylkill or Delaware River, consider FEMA flood insurance — even if you’re not in a flood zone. Rising waters don’t care about maps.

Hiring a Restoration Company? Here’s What You Can Expect

When you hire a professional water damage restoration company, expect them to:

  • Provide moisture readings with advanced tools
  • Tear out damaged drywall/flooring as needed
  • Apply mold inhibitors and anti-microbial treatments
  • Coordinate with your insurer
  • Offer reconstruction services for total restoration

Case Study – Mt. Airy Basement Flood

In early 2023, a family in Mt. Airy had a pipe burst while they were away for the weekend. When they returned, water had saturated their finished basement.

Steps they took:

  1. Shut off the main valve
  2. Took photos & called insurance immediately
  3. Called a local restoration company within 6 hours
  4. Used 3 commercial dehumidifiers for 4 days

Outcome: Covered by insurance, dry within 72 hours, minimal mold. Total cost: ~$3,500
Their neighbor waited 2 days: Mold on drywall, insulation removal, total cost: $13,800
