Manufactured Home Underbelly Repair & Replacement
The underbelly of a manufactured or tiny home, also known as the belly board, bottom board, belly band, or rodent barrier, helps protect the insulation and floor system from pests, moisture, and cold air.
Over time, rodents, wildlife, leaks, and damaged materials can compromise this barrier, leading to torn insulation, energy loss, odors, and damage beneath the home.
At Stillwater Leveling, we provide professional underbelly repair and replacement for manufactured and tiny homes, restoring a clean, secure barrier that helps keep your home protected year-round.
What Happens When the Underbelly Is Damaged
When your underbelly is damaged, these problems can quickly follow:
Rodents or pests nesting inside insulation
Torn insulation hanging down or missing entirely
Cold air and moisture seeping into the floor cavity
Odors or contamination from rodent waste
Increased heating and cooling costs
Sagging insulation or detached belly wrap material
Even small tears can allow rodents in, causing rapid damage throughout your crawlspace.
Restoring a Clean, Sealed Underbelly
Our underbelly repair and installation service restores the protective layer under your home using heavy-duty underbelly materials rated for manufactured housing.
We remove old, contaminated, or torn materials and install new, reinforced barrier sheeting that’s securely fastened and sealed. For homes with partial damage, we offer targeted patching to extend the life of your existing system.
Whether your goal is to repair rodent entry points or completely replace your underbelly, we’ll ensure your home stays clean, sealed, and energy-efficient.

Our Underbelly Repair Process
1
Inspection
We inspect the underbelly, insulation, plumbing area, and crawlspace conditions to identify damage and determine the best repair option.
3
Repair or Replace
We repair damaged sections or replace larger areas with reinforced underbelly material designed for manufactured homes. If needed, new insulation or vapor barrier material can also be installed during this step.
2
Tear out & Preparation
Damaged belly material, loose insulation, rodent debris, contaminated materials, and other debris are removed from the affected areas so the crawlspace can be properly prepared for repair.
5
Optional Vapor Barrier Installation
If the ground vapor barrier is missing, damaged, or heavily contaminated, we can install a new vapor barrier to help protect the crawlspace from ground moisture and keep the area cleaner after repairs are completed. Full vapor barrier installation starts at $2,500.
6
Final Cleanup & Photos
Once the repair is complete, we clean up the work area, remove job-related debris, and provide before and after photos so you can clearly see the finished results.
4
Sealing & Reinforcement
Openings, seams, and vulnerable areas are sealed and reinforced to help protect the insulation, plumbing, and floor cavity from pests, moisture, and cold air.
Frequently Asked Rodent Barrier Questions
-
It’s the black material stretched beneath your home that seals and protects the insulation and floor cavity from pests, moisture, and air leaks.
-
If you see insulation hanging, torn plastic, droppings, or hear scratching under the floor, your underbelly likely needs repair or replacement.
-
Yes, we can reattach or replace damaged insulation before resealing the barrier.
-
Not exactly. A vapor barrier goes on the ground to block moisture from below, while the rodent barrier (underbelly) attaches to the underside of your home’s floor system to protect insulation and structure.
-
With quality materials and installation, your new underbelly can last 15–25 years, depending on soil, moisture, and pest activity.
