From Rot to Rust: What’s Really Happening Under Your Home Without Crawl Space Protection

From Rot to Rust: What’s Really Happening Under Your Home Without Crawl Space Protection

June 03, 20252 min read

If you haven’t looked under your mobile home in a while — or ever — you might be surprised at what’s going on beneath your feet. A crawl space that’s left unprotected can quietly turn into a hazardous zone of moisture, mold, pests, and structural decay.

At Desert Mobile Home Services, we’ve inspected thousands of crawl spaces across Arizona. In many cases, homeowners had no idea their vapor barrier was missing, damaged, or never installed. Here’s what happens when moisture takes over — and how to stop it before it spreads.

🧱 1. Floor Joist & Subfloor Rot

Moisture seeps in from the ground and gets trapped under your mobile home. Without a vapor barrier, it soaks into wooden joists and subfloors, leading to warping, soft spots, and rot. Repairs can cost thousands.


⚙️ 2. Rusted Ductwork and HVAC Damage

Arizona heat makes your HVAC system work hard, and damaged ductwork in a damp crawl space wastes cool air and spikes your energy bills. Over time, rust and corrosion make it worse.


🐜 3. Pest Infestations

Wet, dark crawl spaces are a dream home for rodents, scorpions, and termites. Once inside, they can chew insulation, wiring, and make nests that threaten the health and safety of your home.


🦠 4. Mold and Mildew

Moisture fuels mold growth under your home, which can creep up through the floor and into your walls and vents — impacting air quality and triggering asthma, allergies, or worse.


💸 5. Decreased Home Value

An unprotected crawl space shows up on inspection reports. If you're thinking about selling your mobile home, crawl space moisture or pest damage can lower your resale value or delay closing.


✅ What Crawl Space Protection Looks Like

At Desert Mobile Home Services, we recommend:

  • Installing a professional vapor barrier to block ground moisture

  • Repairing or replacing damaged skirting

  • Sealing gaps and vents

  • Inspecting and securing ductwork and insulation

  • Annual crawl space checkups — especially before monsoon season


📞 Don’t Let Hidden Damage Eat Away at Your Home

A simple crawl space inspection could reveal damage early — and save you thousands later. Whether you’re buying, selling, or staying put, now’s the time to protect what’s underneath your home.
