Understanding the Problem: Why Raised Foundations Lead to Humidity Issues

Raised foundation houses, especially those built in the mid-20th century, often lack proper insulation and ventilation. These homes are elevated above the ground, typically on concrete blocks, which can make them prone to moisture problems if not properly maintained. In many cases, humidity issues in interior closets are exacerbated by poor airflow, nearby water sources (like bathrooms), and lack of insulation.

In one scenario, a homeowner reported that their closet, which shared a wall with a bathroom, had significant humidity issues resulting in mildew growth on clothes. The closet also had an access panel to the pump for a jet tub, which wasn't functioning properly, potentially contributing to the damp conditions.

Steps Taken So Far: What Works and What Doesn't

Based on shared experiences, a few steps have been tried to combat the humidity:

Using DampRid Containers: These moisture absorbers were placed in the closet and refilled monthly or bi-monthly. While they help reduce humidity levels, they aren't a permanent fix for the underlying problem.
Adding Foam Insulation: Blue architectural foam with an R12 value was stuffed into an access hole in the closet. While this provides some insulation, it doesn't address ventilation issues or stop moisture at its source.
Considering a Dehumidifier: Installing a small plug-in dehumidifier in the closet was suggested as another potential solution to actively remove moisture from the air.
Improving Air Circulation: Suggestions included leaving the closet door open and using a small fan to encourage airflow, which can help reduce moisture buildup.
Checking for Water Leaks: Ensuring there isn't a hidden water leak, particularly since the closet shares a wall with a bathroom, is crucial. A persistent drip from a shower faucet was noted, which, while seemingly minor, could contribute to overall dampness over time.

Comprehensive Solutions to Address Humidity Issues

Given the various attempts to solve this issue, let's delve into a more structured approach to tackle the humidity problem in a raised foundation house effectively:

1. Identify and Fix Moisture Sources

Start by identifying any potential sources of moisture:

Inspect for Leaks: Even small drips or leaks from nearby plumbing, such as a shower or sink, can significantly increase humidity levels. It's essential to thoroughly check for leaks in the bathroom adjacent to the closet and ensure all faucets are properly sealed and not leaking.
Check the Foundation and Crawl Space: Raised foundation homes can suffer from moisture seeping up from the ground, particularly if there is a dirt crawl space. If you have access, consider putting down a vapor barrier, like heavy-duty plastic, to reduce ground moisture.

2. Improve Insulation and Sealing

Inadequate insulation can allow humid air to enter the home:

Seal Gaps and Cracks: Ensure that all cracks, gaps, and potential entry points for moist air in the closet and surrounding areas are properly sealed. Use weatherstripping or caulking around doors and windows.
Upgrade Insulation: If feasible, consider upgrading insulation around the closet and in adjacent areas, such as the walls and ceiling that border the closet space. This can help maintain more consistent humidity and temperature levels.

3. Enhance Ventilation

Good airflow is key to reducing moisture buildup:

Install a Closet Vent: If possible, add a vent to the closet that allows for airflow from a less humid part of the house or install a small exhaust fan to help pull moist air out.
Use a Dehumidifier: A small, energy-efficient dehumidifier can be a game-changer for continuously managing moisture in problem areas like closets. Ensure it has an automatic shut-off or a drain hose attachment for convenience.
Add a Fan: A small, quiet fan can be placed in the closet to promote circulation. Ensure clothes are not packed tightly to allow air to move freely around them.

4. Consider Room Dehumidification and HVAC Solutions

For more persistent humidity problems:

Whole-Room or Whole-House Dehumidification: Consider investing in a more comprehensive dehumidification solution. Whole-house dehumidifiers work with your existing HVAC system to manage humidity levels throughout the house.
Maintain HVAC Systems: Regular maintenance of HVAC systems, including cleaning ducts and checking for any moisture buildup or leaks, can improve overall air quality and humidity control.

5. Regular Maintenance and Monitoring

Keeping a close eye on moisture levels and taking proactive steps can help prevent future issues:

Use Humidity Meters: Simple hygrometers can provide real-time readings of humidity levels in different parts of your home, helping you identify problem areas quickly.
Keep Closets Organized: Avoid overstuffing closets, which restricts airflow and traps moisture. Regularly clean and organize to ensure clothes can breathe and stay fresh.

Dealing with Difficult Landlords or Property Managers

If you’re renting and don’t have control over some aspects, such as insulation or significant repairs:

Document Issues and Communicate Clearly: Keep a record of all instances of mildew, mold, or other humidity-related problems. Communicate these with your landlord or property management company in writing.
Know Your Rights: Understand local tenant laws and what you are entitled to in terms of a safe and habitable living environment. Sometimes, a letter from a legal aid organization or tenant rights group can prompt action.

Conclusion

Humidity problems in raised foundation homes can be stubborn, but with a combination of solutions—ranging from improved ventilation and insulation to proper dehumidification—you can create a healthier, more comfortable living environment. While some fixes are straightforward, others may require more effort or negotiation, particularly in rental situations. Remember, addressing moisture at its source is key to long-term success. With persistence and the right approach, you can effectively manage and even eliminate these humidity issues.
