When Should I Re-Insulate my Home?

If your energy bills have been higher than normal or there are drafts and uneven spots inside your house, the energy efficiency of your home isn’t as high as it could be. Many times, this can indicate insufficient amounts of insulation. Do you need to install insulation in your home?

Many homeowners are unsure when it’s time to re-insulate. Talking to an insulation professional is your best bet. In general, older homes tend to not have much insulation, so you most likely need to re-insulate if your home was built in the 1970s or before (though this isn’t always the case). The age of your home isn’t the only way to tell if you need to re-insulate, however.  There are other signs that may indicate your home doesn’t have enough insulation.

When to Re-Insulate Your Home

Signs to be on the lookout for include:

  • Energy bills that are higher than usual for seemingly no reason
  • Drafty, uncomfortable rooms
  • Uneven temperatures throughout the house
  • Air conditioner running more than normal during the summer
  • Ice dams on the roof in the winter
  • Snow melting on your roof in the winter (this indicates a lack of attic insulation)

There are more proactive ways to tell if you need more home insulation—consulting an insulation company! Insulation professionals will be able to tell you if your home has enough insulation and what areas need to be re-insulated. Often, it’s the attic, but many times, walls, basements and crawl spaces aren’t sufficiently insulated.

Installing Insulation

Although the upfront costs may seem high, insulation pays for itself and helps lower your energy bills! It also can help:

  • Make your home more comfortable
  • Improve the efficiency of your air conditioner and furnace
  • Reduce noises from outside and between different rooms and levels inside
  • Potentially increase the resale value of your home; buyers value energy efficiency
  • Contribute to a healthier environment
