Prevention is always easier than repair. While some mobile home settling is inevitable over time, you can take steps to minimize problems and catch issues early before they cause expensive damage.
Understanding Why Mobile Homes Settle
Manufactured homes sit on pier and block systems rather than permanent foundations. This makes them susceptible to ground movement that site-built homes on deep footings would resist. In Florida, the primary causes are:
- Soil compaction over time (especially sandy soils)
- Water erosion around and under supports
- Drought cycles causing soil shrinkage
- Poor original installation or inadequate supports
- Organic material decomposing under piers
Knowing the causes helps you prevent them.
Proper Drainage Is Critical
Water is the number one enemy of mobile home stability. Ensure:
- Gutters are installed and directing water away from the home
- Ground slopes away from the home on all sides
- No water pools near piers or under the home
- Downspouts extend at least 4-6 feet from the home
- French drains or swales redirect problem water
Investing in proper drainage prevents the soil erosion that causes uneven settling. This is especially important in Florida's heavy rain seasons.
Maintain Your Skirting
Your mobile home skirting does more than look nice—it protects the crawl space from weather. Damaged or missing skirting allows:
- Rain to blow under the home and saturate soil
- Animals to dig and disturb pier placement
- Debris accumulation that traps moisture
Keep skirting in good repair with properly installed vents for air circulation. This maintains stable conditions under your home.
Regular Pier Inspection
Once or twice a year, inspect your home's support system:
- Look for leaning or shifted blocks
- Check for gaps between piers and beams
- Ensure shims are still in place and tight
- Look for erosion around pier bases
- Note any new soft spots in the ground
Catching a shifted pier early means simple repositioning rather than extensive re-leveling later.
Control Vegetation
Plants and trees near your mobile home can cause settling:
- Tree roots can lift or shift piers
- Large trees extract moisture, causing soil shrinkage
- Root systems can die and decompose, leaving voids
- Dense vegetation traps moisture against skirting
Keep trees at a reasonable distance (ideally 10+ feet), remove saplings growing near piers, and maintain clear zones around your skirting.
Address Minor Issues Immediately
When you notice early signs of settling—a sticking door, a small crack—don't ignore them:
- Mark cracks with tape and date them to monitor growth
- Note which doors or windows are affected
- Check under the home in those areas for obvious problems
- Call for a professional level check if issues persist
Early intervention often means adjusting a few piers. Delayed action means extensive re-leveling and repairs.
Consider Permanent Pier Upgrades
If your home is on basic concrete blocks, upgrading to more stable systems can reduce future problems:
- Steel adjustable piers allow easier re-leveling
- Concrete pad footings spread weight over larger areas
- Proper blocking configurations distribute loads evenly
These upgrades are worth considering if your home has needed multiple re-levelings or sits on particularly challenging soil.
Monitor After Weather Events
Florida weather can accelerate settling. After hurricanes, heavy rains, or flooding:
- Walk through your home checking for new door/window issues
- Look under the home for water damage or erosion
- Check skirting for damage that might allow water intrusion
- Consider a professional inspection if you notice changes
Storm-related settling can happen quickly and should be addressed before secondary damage occurs.
When to Call a Professional
Schedule professional leveling service when:
- Multiple doors or windows are affected
- Floors feel noticeably uneven
- Cracks are appearing or growing
- It's been more than 3-5 years since last check
- You're planning other repairs or renovations

"Most mobile home settling problems I see could have been prevented or caught earlier with basic maintenance. Good drainage and intact skirting go a long way. And when you notice that first sticking door, that's the time to call—not six months later when there are cracks everywhere."
