How Long Does Attic Insulation Last?

Ontario homeowners learn quickly that having the right amount of high-quality attic insulation is a must during the long winter season. It helps the home retain as much heat as possible while taking some stress off the heating, ventilation, and air conditioning (HVAC) system. Proper insulation is just as important during the summer when you need your home to release excess heat. Getting the ratio of blown-in attic insulation right is crucial all year long if you desire to increase the efficiency of your HVAC system while lowering your heating and cooling costs at the same time.

 How Does Attic Insulation Work?

When a contractor from Ainger Group installs insulation in your attic, it seals gaps between your attic and the outside that could allow cold air into your home in the winter and warm air in the summer. Preventing this leakage of air increases your comfort level as well as reduces energy costs. Another benefit of attic insulation is that it prevents small animals from getting into your attic through openings you didn’t know you had. Sealing gaps with insulation prevents moisture build-up that can lead to toxic mold as well.

 Several Factors Determine How Long Blown-in Attic Insulation Will Last

Perhaps you have seen information online that states attic insulation can last up to 100 years. While that sounds impressive, it is important to understand that several unique factors about your home and attic determine the longevity of insulation in your attic. Some factors to consider include:

  • Do you detect any moisture in your attic that has caused mold, staining, or other common problems?
  • Have you ever experienced a leaking roof?
  • Have any types of animals ever made their way into your attic?
  • Does your attic currently have air leaks?
  • What is the outdoor humidity normally like at your home?
  • How old is your home?

Unfortunately, homes in the Collingwood, Ontario area built more than 10 years ago may not have the highest quality of attic insulation installed. Although you most likely have insulation in your attic, it may not be enough to protect you and your family from typical Canadian weather patterns.

Should You Replace Your Current Attic Insulation?

One of the most obvious signs that you should consider scheduling attic insulation replacement through Ainger Group is when your energy costs continue to climb despite your best efforts at using as little of it as possible. Inadequate attic insulation means your HVAC unit must work harder than necessary to keep your home warm or cool.

Changes in your indoor comfort level are another indication it may be time to replace the insulation in your attic. Please contact us right away if you notice that your home suddenly seems drafty or you have trouble controlling the indoor temperature even with a programmable thermostat.

Pest infestation, mold, or mildew are also common indications that your current attic insulation is no longer performing up to standards. Ainger Group offers free quotes and serves homeowners in the entire Collingwood area.
