5 Reasons Why Homeowners Should Upgrade Home Insulation

As Canadian homeowners, we all want to ensure our homes are comfortable, safe, and energy-efficient. As they are safe spaces, homes should always provide for our needs. However, many may not realize that old or insufficient insulation can significantly hinder achieving these goals. I insulation materials can deteriorate over time, reducing their effectiveness.

Experts recommend upgrading home insulation every 10 to 15 years to ensure optimal performance. There are several types of insulation materials, including fibreglass, cellulose, foam, and radiant barriers. Each has advantages and disadvantages, but why should homeowners upgrade home insulation? Here are some ideas.

1. Healthier Homes

One of the most important reasons to upgrade your home insulation is to create a healthier living environment. Old insulation can become a breeding ground for mould, bacteria, and other harmful pollutants. It can lead to various health issues, including respiratory problems, allergies, and severe illnesses. By upgrading your insulation, you can reduce the risk of these health hazards and breathe easier in your own home.

As insulation ages, it can become less effective at preventing moisture from entering your home. It can damage water, creating the perfect environment for mould growth. Mould can be hazardous to your health, and it can cause a range of health problems, including respiratory issues, allergies, and even asthma. Upgrading your insulation can help to reduce the risk of mould growth in your home.

2. Reduced Mold Risk

As mentioned earlier, old insulation can be a significant source of mould growth because insulation can absorb moisture from the air, creating conditions ideal for mould to flourish. If you notice a musty smell in your home or see signs of mould growth, it may be time to upgrade your insulation. Doing so can reduce the risk of mould and improve the overall air quality in your home.

3. Prevents Air Pollutants From Entering

Another significant benefit of upgrading your insulation is that it can help prevent air pollutants from entering your home. Insulation acts as a barrier between the interior and exterior of your home, preventing outdoor contaminants such as dust, pollen, and exhaust fumes from seeping in. It is essential for those who live in urban areas or near busy roads where air pollution is a significant concern.

4. Ensures Sufficient Insulation

Over time, insulation can become compressed or damaged, reducing its effectiveness. It can lead to drafts, uneven temperatures, and higher energy bills. By upgrading your insulation, you can ensure that your home has sufficient insulation to keep you comfortable and save you money on heating and cooling costs. A professional insulation contractor can assess your current insulation and recommend the best options for upgrading.

5. Energy Savings and Lower Utility Bills

Last but not least, upgrading your home insulation can lead to significant energy savings and lower utility bills. According to Natural Resources Canada, heating and cooling account for up to 60% of a home’s energy use. Upgrading your insulation can reduce the energy needed to heat and cool your home, resulting in lower utility bills and a smaller carbon footprint. Many homeowners report seeing a return on investment within just a few years of upgrading their insulation.


Upgrading your home insulation is a wise investment for homeowners looking to improve their living environment, reduce their carbon footprint, and save money on energy bills. Whether dealing with mould, drafts, or high energy costs, upgrading your insulation can provide many benefits that will pay off for years.
