How to Maintain and Inspect Your Blanket Insulation for Longevity

8 December 2025

Custom Insulation Company, Inc. - How to Maintain and Inspect Your Blanket Insulation for Longevity

Blanket insulation is a reliable way to keep your home comfortable and energy-efficient, but like any home system, it needs a little TLC to perform at its best. Regular maintenance and inspection can help you get the most out of your insulation and avoid costly repairs down the line.

1. Know What to Look For

Start by inspecting your attic, walls, and crawl spaces for any signs of damage. Look for:

Sagging or compressed insulation – This reduces effectiveness.

Moisture or water stains – Damp insulation can lead to mold growth.

Pests or droppings – Rodents can chew through insulation, causing gaps.

2. Keep It Clean and Dry

Moisture is the enemy of blanket insulation. Make sure your attic and crawl spaces are properly ventilated and check for roof leaks or plumbing issues. If insulation gets wet, it may need to be replaced to maintain its insulating power.

3. Avoid Compressing Your Insulation

Stacking boxes or heavy items on top of your insulation can crush it, reducing its R-value and energy efficiency. Keep storage off insulated areas whenever possible.

4. Replace Damaged Sections

If you spot worn-out or damaged sections, don’t wait. Replacing compromised insulation restores energy efficiency and keeps your home comfortable year-round.

5. Schedule a Professional Inspection

Even with regular DIY checks, a professional inspection ensures your insulation is performing at its peak. Experts can identify hidden issues, recommend upgrades, and guarantee your insulation lasts for decades.
