Mobile homes that are placed on pier and anchor foundations can be vulnerable to shifting if they are not set up properly or not maintained. It is a good idea to discuss your home’s foundation with your licensed installer before your home arrives.
The main cause of sinking foundations is due to the ground shifting. This usually happens when the weather changes. Freezing temperatures, rain, and humidity all effect the dirt underneath your home and change it by expanding and contracting. While you cannot control the weather, preventing moisture from accumulating underneath your home will help prevent the soil and foundation from shifting. According to a Manufactured Housing Research Alliance publication, these are some of the main preventative actions you can take.
1. Shed Water
Ensure that your property can shed water. When your land is being prepped, make sure the land is graded so that water will shed away from the home. If not, water could pool underneath the home causing damage. It is also important to be sure your gutter downspouts drain water away from the home. Gutter downspout extensions can be attached to the end of the downspout after your home is placed.
2. Ground Cover
There are a few other things that deserve your attention underneath the home. A proper ground cover under your home will help prevent moisture in the crawl space from entering the home through the floor. Make sure this is installed when the home is initially placed and have the barrier inspected by a professional periodically. Have the vapor barrier repaired or replaced if the inspector finds any tears. Do not attempt to inspect or fix the vapor barrier yourself. Only a professional contractor should go under your home.
Lastly, it is important to keep your skirting in good condition. Skirting keeps critters out and protects the underbelly of the home (pipes included) from the elements and moisture. If you notice a hole or have damaged skirting– consider investing in an update.
There are reasons other than water or moisture that can be the cause of your homes’ sinking foundation. However, these are the most common and preventable reasons. Once your home settles, it can become un-level. Look out for creaking floors, sticking doors, and buckling in the walls or floors. These could be signs of a foundation issue. We hope this helps!
