It Only Takes 48 Hours for Mold to Start Growing…

We get it—life happens. Maybe you were away for the weekend, or figured that small leak could wait until Monday. But the truth is, water damage doesn’t hit pause. Even one weekend of inaction can create a nightmare for your home.


At KOS Restoration, we’ve seen it all—from a dripping pipe under the sink that turned into full-blown mold remediation, to a minor ceiling stain that collapsed into a structural emergency. And the scariest part? Most homeowners never realized how fast it escalates until it was too late.


Let’s break it down.


What Happens When Water Damage Is Ignored for Just One Weekend?

Within the First 24 Hours:

  • Drywall starts to absorb moisture and weaken
  • Wooden floors begin to swell and warp
  • Paint bubbles, and ceilings may start to sag
  • Electrical systems may be at risk if water reaches outlets

By 48 Hours:

  • Mold spores start growing—especially in warm, humid areas
  • Odors begin to develop
  • Metal surfaces begin to tarnish or rust
  • Materials like insulation become saturated and ineffective

After 72+ Hours:

  • Mold colonies can take hold inside walls, carpets, and ceilings
  • Structural supports may start to rot or degrade
  • Sewage backups or contaminants (if present) can create serious health hazards



And the worst part? Insurance claims become more complicated the longer you wait.
