The Benefits of Hiring an Insulation Contractor


Whether you're moving into a new home or considering replacing your old insulation, you must turn to a professional you can trust. If you don't want to gamble with the comfort of those on your property and end up with massive bills, you should leave the insulation installation to a reliable contractor. There are many reasons to do so, such as:

  • The right insulation product: Insulation comes in many forms with unique characteristics. A contractor can help you pick the insulation product that matches your property's design.

  • Old insulation removal: In most cases, you have to remove old insulation before you replace it. You should leave this task to the professionals because it can expose you to mould and asbestos.

  • Full assessment: An insulation professional has the training to inspect your property and identify other energy-saving potentials. We can look for air leaks and poor ventilation, which can enhance your energy efficiency.

  • Efficiency: Professionals like us have the right training, experience and tools to carry out the job correctly the first time. A layperson will only make errors, which can cause damage to your materials and property.

​If you want to enhance your energy efficiency, we recommend choosing our seasoned insulation company in Oshawa. We can protect and enhance your property's values and protect you from moisture damage. What's more, we can work on commercial and residential properties of all types for long-lasting insulation solutions. Please contact us if you'd like a no-obligation quote from us.

Signs You Need to Replace Your Insulation


Typically, insulation can last for years. However, it will eventually wear out and need to be replaced. Failing to replace it on time can cause numerous issues such as unnecessary stress on your HVAC system, poor energy efficiency and increased heating and cooling costs. For this reason, it is essential to identify the signs of insulation damage and replace it on time. The following are the symptoms of insulation that needs to be replaced:

  • Increased use of HVAC system: If you feel that you have to use your air conditioner or heating system more than usual, the problem might be with your insulation. Compromised insulation will let in hot or cold air from outside, which causes your HVAC system to work overtime.

  • The presence of pests: Insects and pests tend to feed off old and worn-out insulation. They can make their way into homes and commercial spaces that aren't properly sealed and cause problems. 

  • Increased energy bills: Insulation that is not doing its job will let in cool and hot outside air. This will place stress on your heating and cooling systems, forcing them to work harder. As a result, your energy bills will increase. If your heating and cooling costs have risen for no apparent reason, you should get your insulation inspected. 

  • Moisture intrusion: The presence of moisture can damage your insulation. Moreover, ineffective insulation also causes water damage. If you notice the growth of mould in your attic or basement or dark spots on your ceilings or walls, you might be suffering from moisture intrusion. 

  • Inconsistent temperatures: The job of your insulation is to maintain comfortable temperatures inside your property. Damaged insulation will cause air leakage, leading to inconsistent temperatures inside your home or commercial property. 

  • Shifting and falling: Insulation can also suffer from visible damage. If you notice your insulation has shifted from your original location or is falling, you should consider insulation replacement. This shifting will prevent your insulation from carrying out its intended job. 

These are only some of the many signs of insulation that should be replaced. If your insulation is old and it's not doing its job, please schedule an assessment with us.
