Out with the Old, in with the New: Why You May Need to Extract Your Old Insulation First

So, you’re thinking about adding new insulation to your home? Awesome choice! A well-insulated house is like a cozy blanket that keeps you warm in winter and cool in summer. But before you start piling on the new stuff, let’s talk about why getting rid of the old insulation first is super important.

1. Rodents LOVE Old Insulation (like, they really love it)

If you’ve ever had a mice problem, there’s a good chance those little critters have turned your attic or crawlspace insulation into their personal playground. Mice and other pests love burrowing into old insulation, leaving behind droppings, urine, and other things we probably don’t even see- but the health effects are just as real. If you just throw new insulation on top, you’re basically saying “You can live here rent free, don’t worry about the damage or smells”. Not exactly the fresh start you want, right?

2. Water Damage: A Slipper Slope 

Had a roof leak? Even if it was years ago, your insulation probably soaked up that water like a sponge. Although Insulation will not get moldy, it will keep your attic beams wet causing the wood to rot. Not only can this cause structural damage, which is a safety concern, but this can also lead to unwanted smells and air quality issues that you didn’t have before. 

3. Better Air Quality = Better Health 

Old, dirty insulation can be packed with dust, allergens, and decades of old contaminants. Every time your HVAC system kicks on, those particles can circulate through your home. Removing that dusty insulation clears out the gunk, making the air in your home fresher and healthier for you and your family.

4. Maximizing Your Investment

Let’s say you decide to skip the removal and just throw fresh insulation on top. The problem? The old, compacted, or damaged insulation underneath can mess with the effectiveness of the new stuff. You’ll be spending money to improve your home efficiency but not getting the full benefit. Think of it like putting a brand-new mattress over a lumpy old one, it just doesn’t work as well.

The Bottom Line? Remove First, Then Upgrade

If your old insulation is compromised—whether from rodents, mold, or just years of wear and tear—removing it is the smartest move before adding new insulation. It’s an investment in your home’s air quality, energy efficiency, and your overall health!
