Mold can start growing within 24 to 48 hours after a water leak if wet materials are not dried. That is why stopping the leak and drying the area quickly matter so much.
Why Mold Grows So Fast
Mold spores are found almost everywhere, indoors and out. They only need moisture, something to feed on, and a little time. Drywall, wood, carpet padding, and insulation all hold water and give mold plenty to grow on. Warm, dark spaces like the inside of walls and under cabinets make growth even faster.
What to Do in the First Day
- Stop the leak by closing the nearest valve or the main shut-off
- Remove standing water with towels, mops, or a wet vacuum
- Pull up wet rugs and move damp items to a dry area
- Run fans and a dehumidifier
- Open cabinet doors and closets so air can move
The goal is to dry the area as fully as possible within one to two days.
Signs Mold May Already Be There
A musty smell is often the first clue. You may also see dark spots on walls, ceilings, or the back of cabinets. Paint that bubbles or drywall that stays soft after drying can mean moisture is still trapped inside.
If you have a large area of mold, or if anyone in the home has breathing problems, it is best to bring in a professional rather than scrubbing it yourself.
Why the Leak Must Be Fixed First
Cleaning mold without stopping the water source will not work for long. As long as the area stays damp, mold will return. Hidden leaks inside walls are a common reason mold keeps coming back.
Repairing the leak that let the water in is the step that keeps mold from returning. If you are not sure where the water is coming from, you can reach a plumber who can help trace it. Call JPR Plumbing at (833) 603-1840.
