When Is It Time To Replace or Upgrade Your House Insulation in Ontario

When Is It Time To Replace or Upgrade Your House Insulation in Ontario -2

As a homeowner in Ontario, it’s essential to ensure that your house is properly insulated to maintain a comfortable living environment, reduce energy consumption, and save money on heating and cooling costs. However, over time, insulation materials can deteriorate, settle, or become damaged, leading to reduced effectiveness and potential issues like drafts, temperature fluctuations, and higher energy bills. Let’s talk about the signs indicating it might be time to replace or upgrade your house insulation and how Canada Energy Solution can help you with professional insulation maintenance and installation services.

Here Are A Few Questions To Ask Before Adding Insulation:

  1. How old is my house? If your house was built more than 15 years ago, it’s likely time to add insulation to your attic. Insulation standards have changed significantly over the years, with the current Ontario Building Code requiring an R-60 insulation level in attics, compared to just R-32 three decades ago. Older homes often have insufficient insulation, leading to increased heat loss, higher energy bills, and reduced comfort levels.
  2. Are there any government grants available? The availability of government grants for insulation upgrades largely depends on current government policies. Canada Energy Solution stays up-to-date on the latest programs and can help you navigate the application process to maximize your savings.
  3. Am I planning any renovations soon? If you’re planning a renovation, it’s an ideal time to consider upgrading your insulation, especially in areas like the attic, walls, or basement. Incorporating insulation improvements during a renovation can be more cost-effective and efficient than tackling the project separately.
  4. What impact will this update have on my home’s efficiency and my energy bills? Upgrading your insulation can have a significant impact on your home’s energy efficiency and monthly utility bills. According to Natural Resources Canada, upgrading attic insulation can result in up to 20% savings on heating and cooling costs, while also improving overall comfort and reducing your home’s environmental impact.

The sole purpose of insulation in any house, especially in Canada, is to regulate the heat flow in a home. In the winter, if a house is properly insulated, it will retain warmth and keep the energy bills low. In the summer, it will allow the house to be cooler.

Have you heard the term R-Value of insulation before?

Insulation is measured by its R-value, which represents the insulation’s resistance to heat flow. The higher the R-value, the more effective the insulation is at preventing heat transfer. In Ontario, the current building code requires an R-60 insulation level in attics, which translates to a depth of approximately 24 inches, depending on the type of insulation used.

When Is It Time To Add Insulation In An Older Home?

If your house was built more than 15 years ago, it’s likely time to add insulation to your attic. Insulation does not need to be replaced unless it has been damaged by pests, animals, or water. The costs of adding and replacing insulation differ, but it is highly recommended to bring your attic insulation up to current standards to ensure long-term energy efficiency and comfort.

What About Adding Insulation To The Exterior Walls?

Replacing insulation in walls can be challenging and may not always be necessary or feasible. Most heat loss from walls occurs through windows, so updating to modern, efficient double-glazed windows is often a more effective solution for older homes. If your house is older than 20 years and has 2×4 framing, updating wall insulation may not be practical. However, if you’re planning a renovation or have walls with little to no insulation, adding insulation can provide significant benefits.

Why Is The Basement Insulation Different In Older Homes Than In Newer Homes?

Basement insulation requirements have evolved. Current standards call for R20 insulation at the full height of the basement wall. When finishing or renovating your basement, it’s highly recommended to bring the insulation up to current standards. In some cases, you may need to remove older insulation and install new material. Failing to update basement insulation during a renovation can lead to condensation issues and potential water damage.

Is Spray Foam Insulation Better For Homes?

Spray foam insulation is a newer product that is mostly used in custom-built homes and specific areas of subdivision homes due to its higher cost. It is an excellent choice for exterior walls, hard-to-reach areas, and garage ceilings. However, it is not recommended for use in attics unless specifically insulating heating ducts, as it can make future changes or upgrades difficult. Additionally, spray foam insulation must be covered with drywall inside the home, adding to the overall cost.



  1. Why is the room above the garage colder?
    This is a common issue caused by cooler temperatures in the garage, whether insulated or not. The current insulation requirement for garage ceilings is R32, but older homes may have lower levels. If you plan to re-insulate your garage ceiling, spray foam insulation is highly recommended, despite the higher cost.
  2. Could I update my attic insulation myself?
    While it is possible to update attic insulation yourself, it’s essential to be familiar with the attic structure to avoid blocking soffit ventilation, which can create significant issues. It’s often best to work with a professional insulation contractor to ensure proper installation and ventilation.
  3. Is there a better type of insulation?
    All currently used insulation types are effective when installed properly. However, it has been noted that cellulose insulation is less attractive to pests like mice compared to other materials.
