Professional Rodent Barrier (Underbelly) Installation & Repair for Manufactured & Tiny Homes
Protect your home’s insulation, plumbing, and subfloor from rodent damage and moisture with a durable, sealed underbelly system.
A rodent barrier, also known as an underbelly, is a critical layer beneath your manufactured or tiny home that seals off the insulation and floor cavity from pests, moisture, and cold air.
Over time, rodents and wildlife can chew through this barrier, tear insulation, and cause significant damage, resulting in energy loss, odors, and structural issues.
At Stillwater Leveling, we specialize in underbelly repair and replacement for manufactured and tiny homes, restoring a clean, tight seal that keeps your home protected and efficient year-round.
What Happens When the Underbelly Is Damaged
When your rodent barrier or 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 or detached belly wrap material
Even small tears can allow rodents in, causing rapid damage throughout your crawlspace.
Restoring a Clean, Sealed Underbelly
Our rodent barrier 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.

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.

With quality materials and installation, your new underbelly can last 15–25 years, depending on soil, moisture, and pest activity.
