The short answer
Act Fast to Dry
After a pipe burst, mold can start growing within 24 to 48 hours. Your first job is to remove standing water and start drying everything. Use mops, towels, and a wet vac to pull up as much water as you can. Open windows if the weather allows, and turn on fans to circulate air.
A dehumidifier helps pull moisture from the air and from porous materials. Run it continuously for several days. If you have a crawl space, a submersible pump can help remove large amounts of water. The goal is to get the space dry before mold takes hold.
Remove Soaked Materials
Porous items like drywall, insulation, carpet, and padding soak up water and can harbor mold. Cut away wet drywall at least 12 inches above the water line. Remove carpet and padding. Dispose of these materials properly, as they are hard to dry completely.
Hard surfaces like wood, tile, and metal can be cleaned and dried. But if wood is heavily saturated, it may need professional drying. In a humid climate, drying can take longer, so consider using a structural drying service to speed up the process. For homes with a crawl space, check for standing water there and use a pump if needed.
- Remove wet carpet and padding
- Cut out wet drywall and insulation
- Discard soaked cardboard boxes
- Take out wet furniture or move it outside
- Open cabinet doors and drawers to air out
Clean and Disinfect
Once the area is dry, clean hard surfaces with a disinfectant. A solution of bleach and water works for many surfaces, but test on a small area first. Wear gloves and a mask to avoid breathing in spores. Scrub surfaces thoroughly and rinse with clean water.
Do not mix bleach with other cleaners, as that can create toxic fumes. For areas that had sewage or floodwater, use a stronger disinfectant and consider professional help. Always follow the product label instructions for safety.
Control Humidity
Mold needs moisture to grow, so keeping humidity low is key. Use a dehumidifier to keep indoor humidity below 50 percent. You can buy a hygrometer to measure humidity levels. Run exhaust fans in bathrooms and kitchens to remove extra moisture.
Fix any leaks or drips right away. If you have a crawl space or attic, check for condensation. In humid weather, air conditioning also helps remove moisture. Keep the air moving with fans, especially in corners and closets.
Know When to Call Pros
If mold covers a large area, or if you see it growing inside walls, call local water damage pros. They have equipment to dry structures thoroughly and to remove mold safely. They can also find hidden moisture with moisture meters and thermal imaging.
Mold can cause health problems, especially for people with allergies or asthma. If you feel unwell, see a doctor. For significant mold growth, a mold professional may be needed. Check your insurance policy to see if mold damage is covered. Policies vary, and your insurer decides what is covered.
- Large mold patches over 10 square feet
- Mold inside walls or under flooring
- You have respiratory symptoms
- Water damage is extensive
- You need help drying structural cavities

How long does it take for mold to grow after a pipe burst?
Mold can start growing within 24 to 48 hours after water damage. That is why quick drying is so important. Remove standing water immediately and start fans and a dehumidifier to dry surfaces. If you cannot dry everything in time, call the pros.
Can I just paint over mold?
No, painting over mold does not kill it. The mold will continue to grow underneath and can damage the paint and drywall. You need to remove the mold first, then dry the surface completely. For porous materials like drywall, removal is often the right option.
What should I do with wet drywall?
Cut out wet drywall at least 12 inches above the water line. Remove the insulation behind it if it is wet. Dispose of these materials. Do not try to dry and reuse them, as they can harbor mold. Replace with new drywall after the area is fully dry.
