Mobile Home Specialists • Crawl Space Health • Rodent Defense
If you own a manufactured or mobile home, your crawl space is the “hidden engine room” of comfort, indoor air quality, and pest prevention. Attic Shield delivers a professional, photo-documented crawl space cleanup that targets the real problems—rodent activity, contaminated debris, damaged insulation, moisture intrusion, and air leakage—then fixes them with proven steps: rodent proofing, insulation removal and installation, and a correctly-installed vapor barrier.
Short version: We remove contaminated materials, address rodent entry points, improve airflow control and insulation performance, and reduce moisture with a vapor barrier—so your mobile home feels cleaner, more comfortable, and easier to maintain long-term.
Many homes need crawl space work and attic work—especially when rodents have traveled from below to above. If you’d like, we can coordinate the full home approach.

Understanding the real issue
A mobile or manufactured home often sits above a vented or semi-vented crawl space, with a perimeter skirt and a network of piers, beams, and access doors. That design can be perfectly safe—until the crawl space becomes a collection zone for debris, moisture, and rodent traffic. When that happens, the air under the home can directly influence the air you breathe inside, especially through penetrations, plumbing openings, and gaps around mechanical systems.
In many mobile homes, insulation is installed beneath the subfloor (often between joists), and it can sag, compress, or become torn. Once rodents nest in that insulation, or moisture saturates it, insulation performance drops fast. You might notice cold floors, musty odors, higher utility bills, dust that returns quickly after cleaning, or rooms that never feel “even.”
The fix isn’t “spray something and hope.” The fix is a professional sequence: remove what’s contaminated or failing, block the rodent pathways that brought the mess, restore insulation where it matters, and add moisture control with a vapor barrier where appropriate.
If you’re seeing any of these, it’s time for a crawl space inspection. Request one here.
Important: Rodent activity and moisture problems are rarely isolated to “just one spot.” Our approach is to identify the pattern—entry points, travel lines, nesting zones, and insulation failure—then correct the system, not just the symptom.
Step 1: remove what doesn’t belong
A true mobile home crawl space cleanup is more than sweeping. It’s the controlled removal of materials that either attract pests, hold moisture, or introduce contaminants into the home. Over time, crawl spaces can collect construction scrap, cardboard, wood, insulation fragments, stored items, plastic, and organic debris. If rodents are present, the crawl space often contains droppings, urine contamination, nesting material, and contaminated insulation—especially near warm zones around plumbing and ductwork.
Our technicians approach crawl space cleaning with a simple rule: remove the conditions that allow problems to continue. We focus on: (1) removing debris and contaminated materials, (2) making the space accessible and serviceable, and (3) preparing surfaces for rodent-proofing work and vapor barrier installation.
When a crawl space is cleaned correctly, other steps become dramatically more effective. Sealing lasts longer. Vapor barriers lay flatter. Insulation stays in place. And you get a crawl space that can be monitored instead of ignored.
We treat your home like a home—not a jobsite. We control access, protect the area near the entry, and work to minimize dust movement. When the crawl space is heavily contaminated, the cleanup plan may include targeted sanitizing steps to reduce odor and contamination risk before the space is sealed and stabilized.
A cluttered crawl space holds moisture and supports rodent activity. Cleaning restores basic hygiene and makes future inspections easier and more meaningful.
Rodent proofing requires access to edges, penetrations, and perimeter zones. Cleanup gives us visibility and working room to do it right.
Vapor barriers fail when installed on messy, uneven, or debris-covered soil. Cleaning first improves durability and appearance.
Step 2: stop the intrusion
Mobile homes commonly have accessible underfloor voids, warm mechanical runs, and perimeter skirt gaps. Rodents look for three things: shelter, warmth, and a reliable path to food and water. The crawl space provides all three, especially when there are openings at the perimeter, penetrations for plumbing and gas lines, and gaps around utility entries.
Many homeowners only notice rodents after the population is established. By that stage, there may already be contamination in insulation, odor near cabinets, and chew damage on ducting or plumbing insulation. That’s why our rodent proofing is designed as a systematic defense: identify entry points, seal and reinforce, and reduce the conditions that invite return activity.

Effective rodent proofing is not just “patch and go.” It’s a plan that is built around the way rodents actually move. Our technicians aim for the highest-impact closures first, then work through the remaining vulnerabilities so the crawl space becomes a poor environment for return activity.
Pro tip: If rodents were active in the crawl space, there is a meaningful chance they also explored the attic. We can align crawl space rodent proofing with attic inspection as needed. If you want, request a full-home check: https://atticshield.com/request/
Step 3: restore thermal performance
Mobile home crawl space insulation often fails in predictable ways: it sags, tears, compresses, or becomes contaminated. Once insulation has rodent droppings or urine contamination, it can hold odor and reduce indoor air quality. Once it’s wet, it loses performance and can encourage mold growth on adjacent materials. And once it’s hanging loose, it becomes a “rodent hammock” that invites nesting.
Insulation removal is not about being aggressive—it’s about being honest. If insulation cannot perform and cannot be cleaned to a safe, stable condition, removal is the professional starting point. We remove failing materials carefully, then prepare the space for better installation that stays in place and performs as intended.

Proper insulation under a mobile home supports comfort and energy efficiency—but it must be installed correctly to last. That means insulation is fitted securely, supported appropriately, and not left vulnerable to sagging or exposure. It also means the crawl space is kept cleaner and more sealed, so insulation does not become the first victim of pests and moisture.
During installation, we focus on consistent coverage and a clean, durable finish. The goal is a crawl space that doesn’t just look “better today,” but holds up season after season.
Sagging creates voids and uneven performance. It also becomes attractive nesting material for rodents, which accelerates failure.
Rodent contamination can introduce odor and unhealthy particles. Removal and controlled cleanup are often the safest path forward.
Wet insulation loses performance quickly. Moisture control—often including a vapor barrier—is critical for long-term stability.
Step 4: moisture control
Crawl space moisture is a silent comfort killer. Moist soil releases water vapor that can rise into the crawl space and interact with cooler surfaces like ducting, pipes, and framing. Over time, that moisture cycle can worsen odors, encourage microbial growth, and reduce insulation performance. Even if you don’t see standing water, moisture can still be present and persistent.
A vapor barrier is a controlled layer that reduces moisture migration from the ground into the crawl space. When installed correctly, it helps stabilize humidity below the home, supports insulation performance, and makes the crawl space cleaner and easier to maintain.
The key words are “installed correctly.” A vapor barrier thrown over debris, left loose at edges, or poorly overlapped will shift, tear, and lose effectiveness. Our approach starts with cleaning and preparation so the barrier has the best chance to last.
Every crawl space is different. That’s why we build the vapor barrier plan around the space itself—soil conditions, clearance height, pier layout, and where moisture is most likely to enter.
Moisture + rodents is a common pairing. A cleaner, drier crawl space tends to be less attractive to pests. That’s why we often recommend a combined plan: cleanup + rodent proofing + vapor barrier + insulation restoration.
Our workflow
We start by evaluating access, clearance, visible contamination, insulation condition, moisture indicators, and rodent entry patterns. Then we create a practical plan that fits your crawl space and your goals—whether that’s odor reduction, comfort improvement, pest defense, or preparing the home for sale.
We focus on clear communication. You’ll know what we found, what matters most, and what steps will produce the best result—not just the biggest estimate.
We remove debris and contaminated materials (when present), and create a cleaner working environment so sealing, insulation work, and vapor barrier installation can be performed properly.
We address entry points and vulnerable zones using durable methods appropriate for the crawl space. The goal is to reduce future intrusion, not just clean the aftermath.
If insulation is contaminated, fallen, wet, or failing, we remove it so your crawl space can be restored the right way. Keeping bad insulation in place is usually a short-term “savings” that becomes a long-term problem.
We install new insulation with attention to consistent coverage and stable placement. Comfort improvements are often noticeable quickly, especially in colder seasons or when floors previously felt “icy.”
We install the vapor barrier after the space is cleaned and prepared, focusing on a flatter layout, reasonable overlaps, and a finished look that makes the crawl space easier to monitor.
We aim to protect the home and keep the process organized. Crawl space projects can be messy—our goal is to deliver a professional result without turning your home into a dust zone.
You should know what you’re paying for and why it matters. We explain priorities so you can make the right decision for your home.
The best crawl space project is the one you don’t have to redo. We focus on steps that reduce recurrence: sealing, cleanliness, moisture control, and proper insulation installation.
Budget with confidence
We don’t believe in mystery pricing. During the inspection, we explain which factors apply to your home and which ones don’t. That keeps the scope clean and prevents surprise add-ons.
The best value comes from doing the work in the correct order. Cleaning without sealing often leads to “rodents return, mess returns.” Sealing without removing contaminated insulation can leave odor and health concerns unresolved. Installing a vapor barrier over debris reduces lifespan and appearance. Our process is built to protect your investment.
If you’re planning to sell, refinance, or simply want long-term peace of mind, a professional crawl space project can be a major differentiator. Buyers and inspectors notice when the “below-home” area is clean, sealed, and documented.
Transparency
Crawl spaces are out of sight—so most homeowners never truly know what was done. Attic Shield documents the major milestones of the job so you can see meaningful progress. That typically includes photos of key phases such as removal/cleanup, sealing progress, and final results.
This documentation helps in multiple ways: it improves accountability, supports property records, helps with real estate transactions, and gives you confidence that the problem was addressed with a complete approach.

Answers
Common signs include musty odors, cold floors, rodent noises under the home, droppings near cabinets or plumbing, sagging insulation, and visible debris near the access door. An inspection is the fastest way to confirm conditions and determine whether cleanup, rodent proofing, insulation work, or a vapor barrier is the right solution.
Trapping reduces activity, but it doesn’t remove the entry routes. If the pathways remain open, future intrusion is likely—especially in mobile home crawl spaces where access points can be easy to exploit. Sealing vulnerabilities is what turns short-term relief into long-term control.
Not always—but often. If insulation is contaminated, wet, torn, or hanging, removal is typically the safest and most effective approach. If insulation is still stable and not contaminated, localized repairs may be possible. We evaluate the condition and recommend the most practical path.
A vapor barrier reduces moisture migration from the ground into the crawl space, helping stabilize humidity. This supports insulation performance, reduces musty odor potential, and creates a cleaner environment under the home. The value depends on site conditions and proper installation.
Yes. Air can move between the crawl space and living areas through gaps, penetrations, and mechanical pathways. If the crawl space contains rodent contamination, damp debris, or failing insulation, it can contribute to odors and particles that homeowners often notice indoors.
Yes. If rodents were active in the crawl space, we can also evaluate attic conditions when needed. Many homes benefit from a combined approach: crawl space cleanup and sealing plus attic insulation removal/installation, sanitization, and air sealing.
