The short answer
Dry Wet Areas Fast
Mold needs moisture to grow, so the first step is to remove any standing water and dry out the affected area. Use towels, a wet vacuum, or a mop to soak up water, then open windows and doors to let in fresh air. If you have a dehumidifier, run it to pull moisture from the air.
Focus on hidden spots like under cabinets, behind baseboards, and inside closets. Mold can spread quickly through porous materials, so check for dampness in carpets, drywall, and insulation. The longer materials stay wet, the higher the risk of mold taking hold.
Lower Indoor Humidity
Keeping indoor humidity below 50 percent makes it harder for mold to spread. Use exhaust fans in bathrooms and kitchens while cooking or showering, and vent the dryer to the outside. In a climate like Redmond's, with its mild marine climate, indoor humidity can stay high during wet seasons, so run a dehumidifier in basements or other damp spots.
Check for leaks in your roof, plumbing, or windows that add moisture to the air. Fixing a small drip now prevents a bigger mold problem later. Also, avoid drying clothes indoors, as that releases a lot of moisture into the air.
- Run exhaust fans during and after showers
- Use a dehumidifier in damp rooms
- Fix any leaks in pipes or roof
- Vent the dryer outside
- Keep indoor humidity below 50 percent
- Open windows when weather allows
Clean Small Mold Spots
For small areas of mold, like on tile or glass, you can clean it yourself with a solution of water and mild detergent or a store-bought mold cleaner. Wear gloves and a mask to avoid breathing in spores. Scrub the surface thoroughly, then dry it completely.
Do not use bleach on porous surfaces like wood or drywall, as it may not kill the mold roots. After cleaning, watch the area for a few days to see if mold returns. If it does, the mold may be deeper than the surface, and you may need to remove the material.
Remove Porous Materials
Porous items like drywall, carpet, ceiling tiles, and insulation that have been wet for more than 24 hours often need to be cut out and thrown away. Mold can grow inside these materials, and cleaning the surface is not enough. Cut away the affected section, plus a little extra around the edges, to be safe.
For valuable items like furniture or books, you might try drying them out in the sun or with a fan, but if they smell musty or show visible mold, it is safer to discard them. Remember to wear protective gear when handling moldy materials, and seal them in plastic bags before disposal.
- Cut and discard wet drywall and insulation
- Remove and replace soaked carpet and padding
- Throw away moldy ceiling tiles
- Seal moldy items in plastic bags
- Dry salvageable items outdoors if possible
When to Call the Pros
If mold covers more than a small area, like a patch larger than a few square feet, or if it keeps coming back, it is time to get help. Local water damage pros have the equipment and experience to handle large mold problems safely. They can also identify the source of moisture that is feeding the mold.
Before calling, take note of the affected areas and any visible leaks. This information helps the pros assess the situation. They may use moisture meters and air scrubbers to find hidden mold and dry out the structure. In some cases, they might recommend removing and replacing drywall or other materials.
If you live in Redmond, keep a list of trusted local pros handy. Also, check your insurance policy to see if mold damage is covered. Policies vary, and your insurer decides what is covered.

Can I paint over mold to stop it from spreading?
Painting over mold does not stop it. The mold will continue to grow underneath and can eventually push through the paint. You need to clean or remove the mold first, then address the moisture problem. Only after the surface is dry and clear of mold can you paint.
How long does it take for mold to spread after water damage?
Mold can start growing within 24 to 48 hours after materials get wet. It can spread quickly, especially in warm, humid conditions. That is why it is important to dry out wet areas right away. The longer the moisture remains, the more extensive the mold growth can become.
Is all mold dangerous?
Not all mold is toxic, but any mold can trigger allergies or respiratory issues in some people. If you see mold, clean it up promptly. If you feel unwell, see a doctor. For large infestations, professional help is recommended to ensure safe removal.
