How Long Does Insulation Last: When to Replace It

Are you looking to save money on your home? If you haven’t considered insulating your home, it’s a solution you may want to think about. Many homeowners aren’t aware of the signs that indicate more insulation should be installed, but insulation offers a lot of potential for year-round savings!

Re-insulating your home is a great way to save money in the long run. Often, homeowners don’t realize that old insulation becomes much less effective over time, allowing heat to escape in the winter and essential air conditioning to escape in the summer, which can increase your energy bills.

Insulation typically lasts 15 to 20 years, meaning that addressing your home’s insulation needs early on can save you money starting now.

How Long Does Insulation Last?

It starts with how old your insulation is. Unfortunately, insulation doesn’t last (and perform effectively) for years and years; as mentioned, the typical lifespan of insulation is 15 to 20 years.

If you just moved into a newly built house 2 years ago, you’re most likely good to go. Modern homes are well-insulated and more energy-efficient than homes built even a decade ago! Below are two situations, however, where you should consider calling an insulation company for re-insulating services:

  • Your home was built in the 1970s or earlier
  • You’ve been living in your home for years without ever checking things like insulation levels (especially if you’re not sure when your home was built)

Insulation installed many years ago can start to sag, deteriorate or get infested with rodents, significantly decreasing its effectiveness.

In addition to old age, other signs you may need more insulation include:

  • Drafts (particularly near the windows) and uneven temperatures from room to room
  • Higher-than-normal energy bills for the time of year
  • Your air conditioning or heating systems running more than normal
  • An unusually warm second story (which indicates you may need more attic insulation)
  • Moisture damage from water leaks
  • The insulation settling and compressing, limiting its ability to trap heat effectively

Signs That You Need to Replace Your Insulation

Tackling poor insulation head-on and replacing it as needed is your best bet at restoring whole-home efficiency and comfort. Whether you use fiberglass, cellulose, mineral wool or another insulation material, it all deteriorates and loses efficiency at some point. Have your insulation professionally replaced if you notice any of these signs:

  • Your energy bills are rising despite normal usage
  • Your home has an uneven temperature throughout
  • You notice drafts or cold spots in certain areas
  • Mold, mildew or moisture damage is present
  • Your allergies or respiratory issues are heightened
  • Pests are infesting the insulation material
