How to Keep Water From Running Under Mobile Home

Mobile homes are a popular housing option for many people due to their affordability and flexibility. However, one common issue that mobile homeowners face is water running under their homes. This can lead to various problems, including moisture damage, mold growth, and even structural issues. To prevent water from running under your mobile home, here are some effective tips to follow:

1. Install Skirting: Skirting is a barrier that surrounds the bottom of your mobile home, preventing water from flowing underneath. It is typically made of vinyl or metal and is available in various styles and colors. Ensure that the skirting is properly installed and sealed to create a tight barrier against water.

2. Create a Slope: It’s important to ensure that the ground around your mobile home slopes away from the foundation. This will help divert water away from the home, preventing it from accumulating and seeping under the structure. Use a shovel or hire a professional to grade the soil properly.

3. Extend Downspouts: Make sure your downspouts are directing water away from the foundation of your mobile home. Consider installing extensions to carry the water further away, ideally at least 10 feet away from the home. This will help prevent water from pooling near the foundation and seeping underneath.

4. Install a French Drain: A French drain is a trench filled with gravel or rock that helps divert water away from your home’s foundation. Dig a trench around the perimeter of the home, sloping away from the foundation, and fill it with gravel. This will collect and redirect water, preventing it from flowing under your mobile home.

5. Maintain Gutters: Regularly clean and maintain your gutters to ensure they are free from debris. Clogged gutters can cause water to overflow and pool near the foundation, increasing the risk of water seeping under your mobile home. Additionally, ensure that your gutters are securely attached to your home to prevent water from dripping down and pooling near the foundation.

6. Use Moisture Barriers: Consider using moisture barriers, such as heavy-duty plastic sheeting or landscaping fabric, to further protect your mobile home from water intrusion. These barriers can be placed on the ground before installing skirting and act as an additional layer of protection against moisture and water seepage.

7. Regularly Inspect and Maintain: Regular inspections and maintenance are crucial to keeping water out of your mobile home. Check for any signs of water damage or moisture buildup regularly. Repair any damaged skirting, downspouts, or gutters promptly to prevent water from running under your home.


1. Can I use gravel as skirting instead of vinyl or metal?
While gravel can provide some protection, it is not as effective as vinyl or metal skirting. Gravel alone may not create a tight barrier against water, allowing it to seep through. It is best to use purpose-built skirting materials for optimal protection.

2. How often should I clean my gutters?
It is recommended to clean your gutters at least twice a year, preferably in spring and fall. However, if you have many trees around your mobile home, more frequent cleaning may be necessary to prevent clogs.

3. Can I install a French drain myself?
Installing a French drain can be a complex task. It involves digging a trench, ensuring proper slope, and filling it with gravel. It is recommended to hire a professional to ensure it is done correctly.

4. Will skirting alone prevent all water from running under my mobile home?
While skirting is an essential part of preventing water intrusion, it may not completely eliminate the risk. It is crucial to combine skirting with proper grading, downspout extensions, and regular maintenance to effectively keep water from running under your mobile home.

5. How do I know if water is running under my mobile home?
Signs of water running under your mobile home may include a musty odor, dampness or standing water in crawl spaces, or visible moisture damage on the walls or floors. Regular inspections can help detect these issues early.

6. Can I use landscaping to prevent water from running under my mobile home?
Landscaping can help divert water away from your home, especially by creating slopes and using plants that absorb excess moisture. However, it should be used in conjunction with other preventive measures for optimal results.

7. What should I do if I already have water damage under my mobile home?
If you notice water damage under your mobile home, it is crucial to address it promptly. Consult a professional to assess the extent of the damage and recommend appropriate repairs. Additionally, identify and fix the source of the water issue to prevent further damage in the future.
