Do you need to re-insulate your home? It can be a good way to increase energy efficiency and save money—but what if you have old insulation in your home? Can it be removed?
The short answer is yes, insulation can be removed.
Removing Insulation & Adding New Insulation Over Old Insulation
Sometimes insulation removal isn’t necessary—new batt or rolled insulation, or blown loose-fill cellulose or fiberglass, can often be installed over old insulation. But it’s important to keep the following in mind:
- “Faced” insulation should not be placed on top of existing insulation in the attic. Batt or roll insulation installed over existing insulation in the attic shouldn’t have a vapor retarder (face), which can trap moisture. Existing batt or roll insulation should have the facing against the attic drywall floor or no facing at all.
- Insulation should be rolled out perpendicular to the joists—and unfaced rolls should be used.
- Rolled insulation should not be tacked down (if the insulation is flattened, the R-value can decrease).

An insulation company should be handling the removal and installation process for you, but the information can still be helpful to know. All of that said, there are times when insulation should be removed and replaced.
When Should Insulation Be Removed?
You should remove insulation in your walls, attic or crawl space if it is:
- Wet or damp
- Moldy
- Sagging or loose
- Damaged by fire or anything else
