The short answer
Find and Fix Moisture Sources
Humidity rises when moisture enters your home from leaks, damp crawlspaces, or everyday activities like cooking and showering. Check for plumbing leaks, roof gaps, and foundation cracks. A small drip can add gallons of water to the air over time, so fix any issues you find quickly.
In a humid climate, storms can damage roofs and windows, allowing moist outdoor air to seep in. After any heavy rain, inspect your attic and walls for damp spots. If you suspect hidden moisture, a professional leak detection service can locate the source accurately.
- Inspect roof shingles and flashing after storms
- Check plumbing under sinks and around toilets
- Look for condensation on windows and pipes
- Seal gaps around doors and windows
- Fix gutter downspouts that direct water toward the foundation
Improve Ventilation
Good airflow helps carry moist air outside before it settles into walls and furniture. Use exhaust fans in bathrooms and kitchens whenever you cook or shower. Open windows when outdoor humidity is low, especially during cooler mornings or evenings.
If your home feels stuffy, consider a whole-house ventilation system or a heat recovery ventilator. These exchange stale indoor air with fresh outdoor air while minimizing energy loss. In humid climates, a dehumidifier can also pull moisture from the air, keeping relative humidity below 50 percent.
Use Dehumidifiers Wisely
A dehumidifier is one of the most effective tools for lowering indoor humidity. Place it in the most humid rooms, such as laundry areas or bathrooms, and empty the water collection tank regularly. For larger spaces, a portable unit with a higher capacity may be needed.
Set your dehumidifier to maintain a relative humidity of 40 to 50 percent. Lower settings can over-dry the air, which may cause wood to crack or static electricity. If you have central air conditioning, running it also removes moisture, so use both systems together for the right results.
Dry Wet Materials Quickly
Wet carpets, drywall, and insulation can hold moisture for days, driving up humidity and promoting mold growth. If you experience a leak or flood, remove soaked items and use fans to speed drying. In severe cases, you may need to remove and replace damaged materials.
Professional structural drying and dehumidification services use industrial equipment to draw moisture from walls, floors, and ceilings. This process can prevent long-term damage and reduce the risk of mold. Acting quickly is key, as damp materials become harder to dry over time.
- Remove standing water with a wet/dry vacuum
- Pull up wet carpet and padding
- Cut away soaked drywall and insulation
- Run fans and dehumidifiers continuously
- Open closet and cabinet doors to let air circulate
Seek Professional Help for Persistent Issues
If humidity levels stay high despite your efforts, hidden moisture may be the cause. A water damage inspection can identify damp spots in walls, ceilings, and floors using moisture meters and thermal imaging. This helps you target your efforts and avoid costly guesswork.
For ongoing problems, local water damage pros can provide structural drying and dehumidification services to restore a balanced indoor environment. They can also map moisture levels to ensure no area is overlooked. Policies vary, and your insurer decides what is covered, so check your policy for details.

What humidity level should I aim for indoors?
Aim for a relative humidity between 30 and 50 percent. Levels above 60 percent can encourage mold and mildew growth, while below 30 percent may cause dry skin and static electricity. Use a hygrometer to monitor and adjust your dehumidifier settings accordingly.
Can houseplants increase humidity in my home?
Yes, houseplants release moisture through transpiration. If you have many plants, they can raise indoor humidity, especially in closed rooms. To counteract this, you can reduce the number of plants in high-humidity areas or increase ventilation and use a dehumidifier.
Should I open windows to lower humidity?
Only if the outdoor air is drier than the indoor air. In humid climates, opening windows during the day can let in more moisture. Check the outdoor humidity first; if it's lower, open windows for a short time. Otherwise, rely on exhaust fans and dehumidifiers.
