How to Tell When it’s Time to Re-Insulate

Do you know if you need to re-insulate your home? You probably answered “no,” which is normal—most homeowners don’t have the necessary tools and expertise to figure out their insulation needs. This is where professional insulation companies like ThermaSeal / Lakeside Insulation can help!

Typically, a lot of older homes (built in the 1970s or before) don’t have enough insulation or meet the U.S. Department of Energy’s latest recommendations. However, this isn’t always the case, so make sure you check with a professional insulation company. Besides the age of your home, other indicators that you may need to re-insulate your home include:

  • Energy bills that are higher than usual for seemingly no reason (check them in comparison to how they were at the same time last year—there might be a problem if they are significantly higher)
  • Drafty, uncomfortable rooms or uneven temperatures throughout the house (this could indicate that you don’t have enough insulation in your walls)
  • Air conditioner running more than usual during the summer (if your home isn’t properly insulated, more heat leaks in during the summer, which causes your AC to work harder)
  • Ice dams forming on the roof or snow melting off it too quickly in the winter (these signs both usually mean you don’t have enough attic insulation)

There are also more proactive ways to tell if you need more home insulation—you can check certain areas yourself. While looking behind your siding may be something you can’t handle on your own, it is easy enough to open your HVAC closet and look at your ducts or remove electrical outlet plates to take a quick peek behind your walls (turn off the power to the outlets before you do this).

Additional Ways to Tell if You Need More Home Insulation

Things like looking behind your electrical outlets and checking for drafts or warm spots in your home are easy to do on your own, but you have other choices as well. You can:

Get a home energy audit: Although not your cheapest option, an energy audit can reveal not only whether you need more insulation but also where you need to insulate and other areas you could improve your energy efficiency efforts. For instance, audits can determine where you need to air seal (which is important because air leaks undermine the performance of your insulation).

Talk to an insulation company: Your absolute best bet to determine if you need to re-insulate your home is to talk to a professional insulation company. They will be able to confirm that you do need more insulation, as well as where you need to insulate and how much insulation you need.
