Belly Wrap Replacement
Mobile Home Belly Wrap Replacement in Kansas City
The belly wrap is the bottom board under your home. It holds the insulation in, keeps animals and moisture out, and protects your pipes and ducts. When it tears or sags, everything above it is exposed. Here is what it is and how we replace it so it stays up.
What Is the Underbelly of a Mobile Home?
The underbelly is the system hanging under the floor of a manufactured home: insulation in the floor joist cavity, with a belly wrap (also called belly board or bottom board) stretched underneath to hold it all in. From the factory it hangs between the beams in a shallow bowl shape.
Over the years it gets torn by animals, snagged during other work, soaked by leaks, or just sags as the material ages. Once a section fails, insulation falls out, pests move in, and the damage spreads.
Cross Section
How the Layers Go Together
Joists run across the home and rest on the beams, which run its length. The belly hangs in a bowl between the beams. The detail that makes a repair last is how that bowl is held up.
Our Process
How We Replace It
- 1Inspect and document
We photograph the whole belly and every damaged area, and check for active leaks, structural damage, or moisture sources. We do not close up a belly over an active leak.
- 2Remove what failed
Torn belly material and wet or contaminated insulation come out and are bagged for disposal.
- 3Seal before insulating
Leaks are fixed, loose ducts are reconnected and sealed, and gaps around plumbing and duct penetrations are closed. None of this can be reached once the belly is closed.
- 4Insulate the full cavity
Insulation goes in to match what was there, filling the cavity between the joists without gaps and without being squashed.
- 5Hang new belly wrap beam to beam
New wrap is bonded to the existing wrap with contact adhesive, then hung in the same bowl shape as the factory original.
- 6Hold it up with 1x2 strips
A 1x2 strip runs along each beam, tight against it, under the edge of the wrap. We screw up through the strip and the wrap into the bottom of the joists, which keeps the belly up permanently.
- 7Tape seams and openings
Deck joint tape goes over seams, rips, and penetrations. Every opening is closed so animals cannot get back in.
Why New Wrap, Not Just Tape
Every repair we do is covered with new belly wrap rather than taped alone. Tape on its own tends to let go, and that is when the belly starts to sag again. New wrap, adhesive, and strips fastened to the joists turn a patch into a repair that holds.
Our work is backed by a lifetime transferable warranty that passes to the next owner at no cost.
FAQ
Belly Wrap FAQ
What is belly wrap on a mobile home?
It is the bottom board that holds the insulation up under the floor and acts as the barrier against animals and moisture. It is also called belly board or bottom board.
Why does my belly wrap sag?
Age, moisture, animals, or insulation weight pulling on a torn section. A sag usually means a section has failed, and it tends to get worse.
Can you just tape a torn belly?
Tape alone does not last. We cover repairs with new belly wrap, bond it to the old wrap with adhesive, and fasten it with 1x2 strips so it stays up.
Do you replace the whole belly or just the torn part?
It depends on the inspection. A single damaged section can be repaired. Widespread damage is usually better value as a full replacement.
How long does belly wrap replacement take?
Many repairs take a day or less. Larger homes or full replacements can take a few days, depending on access and how much insulation and ductwork needs work.
