How to Maintain and Inspect Your Blanket Insulation Over Time

25 February 2026

Custom Insulation Company, Inc. - Blanket Insulation

Blanket insulation is one of the most effective ways to keep your home comfortable and energy-efficient. But like any home feature, it requires regular maintenance to ensure it continues performing at its best. Here’s how you can inspect and maintain your blanket insulation over time.

1. Check for Visible Damage

Start by inspecting your insulation for signs of wear and tear. Look for areas that are compressed, torn, or water-stained. Moisture damage can lead to mold growth and reduce insulation efficiency, so it’s essential to catch it early.

2. Ensure Proper Coverage

Blanket insulation works best when it completely fills the space without gaps. Inspect your attic, walls, or crawl spaces to make sure there are no bare spots or sagging sections. Any gaps can allow heat to escape, lowering your home’s energy efficiency.

3. Watch for Pests

Rodents and insects can sometimes nest in insulation, which can damage the material and create hygiene issues. Look for droppings, nesting materials, or chewed insulation, and take action if needed.

4. Maintain Proper Ventilation

Proper airflow in your attic and walls helps prevent moisture buildup, which can degrade insulation over time. Make sure vents are unobstructed and functioning correctly.

5. Schedule Professional Inspections

While basic checks can be done on your own, a professional inspection every few years can help identify hidden problems. Experts can measure your insulation’s R-value, check for settling or compression, and recommend upgrades if necessary.

6. Upgrade When Needed

If your insulation is old or damaged, consider adding new blanket insulation or replacing the worn sections. Modern insulation materials are more energy-efficient and can help reduce your heating and cooling costs.

Maintaining your blanket insulation doesn’t have to be complicated. Regular inspections and timely upkeep will ensure your home stays comfortable, energy-efficient, and safe for years to come.
