First steps for mobile home water damage

  1. 1

    Shut off the water

    The main shutoff is usually under the home near where the supply enters, or at the park's meter.

  2. 2

    Stay off soft floor areas

    Swollen particleboard can give way underfoot.

  3. 3

    Look for sagging belly wrap

    A bulging underbelly often means water is pooling above it.

  4. 4

    Tell the park management

    Many San Marcos parks handle the service line up to the home.

The standard

How mobile home water damage is handled

Checking under the floor

The walkthrough tech reads the subfloor from above and checks the belly from below, where water from supply lines pools unseen.

Removing what swelled

The mitigation team cuts out swollen particleboard decking and soaked belly insulation, because they rarely recover once saturated.

Drying the floor system

The drying team dries joists, remaining decking and wall bottoms with air movers and dehumidifiers until readings meet the goal.

Why manufactured homes need a different approach

San Marcos has many manufactured-home communities, including around Lake San Marcos and along the SR-78 corridor. In these homes the supply and drain lines run under the floor, wrapped inside a vapor barrier called the belly. A leak there can pool on top of the belly wrap for weeks, soaking insulation and the underside of the subfloor while the carpet above looks normal.

  • Soft or spongy spots near the bathroom, kitchen or water heater
  • A sagging or torn underbelly
  • Musty odor from floor registers
  • Higher water bills with no visible leak

Particleboard does not dry back

Many older manufactured homes use particleboard decking, which swells and loses strength once wet. The mitigation team removes swollen sections rather than drying them, then dries the joists and the remaining floor. Wet belly insulation is removed so air can reach the frame, and the belly is closed after the plumber repairs the line.

Questions

Mobile home water damage questions

Water under a manufactured home hides inside the belly long before the floor feels soft.

(888) 450-9281
What is the belly of a mobile home?

It is the vapor barrier wrapped under the floor that holds insulation and protects the plumbing. Water from a leak can pool on it, out of sight.

Can swollen particleboard be dried?

Usually not. Particleboard that swelled has lost strength and is replaced. Plywood and joists can often be dried in place.

Who handles the water line to the home?

In many parks, management handles the service line up to the home and the owner handles the plumbing inside. Check your park rules.

How long does drying take?

After removal of swollen decking and wet insulation, drying typically takes two to four days.

Is mobile home water damage covered?

Many manufactured-home policies cover sudden leaks; long-term leaks and wear may not be. Coverage depends on your policy, so it is worth checking with your own insurer.

How can I prevent belly leaks?

Check under the home once a year, fix torn belly wrap, insulate exposed lines and install a leak sensor near the water heater.
