Why Remove Old Insulation?
Homeowners in San Diego are often surprised to learn that insulation doesn’t last forever. Over time, even the best insulation degrades, collects contaminants, and loses its effectiveness. Here’s why you may need to remove it:
1. Rodent Contamination
Rodents love attics. They nest in insulation, leave droppings and urine, and chew through ductwork and wires. Once insulation is contaminated, it becomes a health hazard and must be removed—not just covered up.
2. Moisture Damage or Mold
In San Diego’s coastal and canyon areas, attics are vulnerable to humidity and condensation. Wet insulation loses its R-value and becomes a breeding ground for mold and mildew.
3. Dust and Airborne Allergens
Old, dusty insulation collects pollutants over decades. This can contribute to respiratory issues, allergies, and poor indoor air quality.
4. Fire Hazards
Outdated insulation—especially older fiberglass or vermiculite types—can be flammable or degrade near heat sources. It’s not worth the risk.
5. Energy Inefficiency
Insulation settles, compresses, and breaks down. Once that happens, it no longer regulates your home’s temperature, which increases your energy bills.
6. Home Renovations or Upgrades
If you’re remodeling, re-roofing, or upgrading HVAC systems, it’s the perfect time to remove and replace your attic insulation.
Signs It’s Time to Remove Your Attic Insulation
Here are the most common symptoms San Diego homeowners notice:
- Odd smells coming from the attic
- Unusual temperature swings in rooms below the attic
- Increased allergies or respiratory issues
- High energy bills with no clear cause
- Rodent activity or droppings in the attic
- Wet or compacted insulation visible around the hatch
- Discoloration or sagging insulation batts
If you notice any of these signs, don’t wait. Removing contaminated insulation now can prevent bigger problems (and bigger costs) later.
The AtticShield Insulation Removal Process
We follow a detailed, six-step process to safely and thoroughly remove insulation from attics and crawlspaces across San Diego.
🧰 Step 1: Free Inspection & Assessment
We start with a free on-site inspection. Our trained technicians examine:
- The condition and type of existing insulation
- Rodent or moisture damage
- Entry points for pests
- Air sealing opportunities
- Photos and documentation for your records
We’ll walk you through what we find and provide a detailed quote for removal and replacement.
🧹 Step 2: Site Preparation & Containment
Before we begin, we protect your home:
- We lay down protective sheeting from the front door to the attic
- Create a sealed tunnel to prevent dust migration
- Use plastic sheeting, zip walls, and HEPA-rated vacuums
- Wear full PPE (respirators, gloves, coveralls) to protect your home and our crew
Cleanliness and care are non-negotiable at AtticShield.
💨 Step 3: Insulation Removal
Depending on the type of insulation, we use different techniques:
For blown-in insulation (fiberglass or cellulose):
We use a 20-horsepower industrial vacuum to suction insulation directly into sealed disposal bags located outside the home. This keeps everything clean and discreet.
For batts insulation:
We manually remove and bag insulation inside the attic, minimizing dust and debris. Any leftover debris or rodent waste is vacuumed thoroughly.
🦠 Step 4: Rodent Droppings & Debris Removal
If rodents were present, we don’t just remove the insulation—we clean the mess they left behind.
We remove:
- Feces and urine-soaked materials
- Rodent nests and food caches
- Contaminated HVAC duct insulation
This helps restore a healthy indoor environment and eliminates scents that attract future pests.
🧼 Step 5: Sanitization & Deodorizing
We apply an EPA-approved disinfectant to sanitize the attic and neutralize odors. This step is especially important in San Diego’s older homes, where contamination is common.
For homes with extensive damage, we also offer fogging and rodent-proofing upgrades.
✅ Step 6: Final Inspection & Readiness for New Insulation
After cleanup, we inspect the attic once more, ensure all debris is removed, and prepare the space for new insulation installation, air sealing, or duct repair.

Can’t I Just Add New Insulation on Top?
This is one of the most common questions we get. And the answer is: sometimes, but rarely recommended.
Covering up old insulation may:
- Trap odors or contaminants
- Prevent you from addressing rodent infestations
- Add unnecessary weight on your ceiling joists
- Reduce air flow and increase humidity problems
- Waste money on inefficient upgrades
We strongly advise removing compromised insulation before starting any upgrades. That’s why we specialize in full-service removal and replacement for long-term results.
