5 Common Insulation Problems and Their Solutions

Insulation helps keep the temperature inside your home comfortable and stable. Over time, however, it can wear out and become less effective. To ensure your insulation is still doing its job, look for the following signs that it is time to replace it: Drafts, higher energy bills, uneven temperatures, and visible signs of damage. By understanding the signs that your insulation is failing, you can keep your home comfortable and energy-efficient for years to come.

Here are the top five insulation issues you might encounter:

1. Wear and Tear

Homeowners may experience recurring issues such as high energy bills, drafts, and other uncomfortable home conditions. By inspecting the insulation in areas such as the attic, basement, and ductwork, homeowners can identify signs of aging, wear on the insulation, and other inefficiencies that can be improved with new insulation. Updating the insulation can help reduce energy costs and make the home more comfortable.

2. Mouldy Insulation

When insulation gets wet, it can cause many issues. One of the biggest concerns is mould growth, which can occur in any area where water damage occurs. This includes walls, roofs, and basements. Wet insulation also allows air to move freely, creating drafts that make a home too hot or too cold. Mould spores can also spread through an HVAC system if it is not properly insulated. Mould can be a health hazard, and it can also devalue a home. It is best to hire a professional remediation company to remove the mould. Once the mould is gone, the damaged insulation can be replaced.

3. Water-Damaged Insulation

Colorado’s climate is generally quite dry, but certain areas of your home can still be vulnerable to water damage from rain, snow, and ice. It’s important to address any water leaks or damage as soon as possible, especially in areas like the roof or foundation. Certain insulation materials, such as mineral wool and spray foam, are resistant to water and can help protect your home from water damage. Other common insulation materials, like fibreglass, can be ruined when exposed to moisture, so it’s important to select the right material for your home.

4. Damage Caused by Animals

Insulation made of fibreglass is popular for households since it provides a warm and cozy environment. Unfortunately, this also makes it a desirable place for creatures like mice, rats, squirrels, bugs, birds, raccoons, and bats to nest. Older homes are particularly vulnerable to these kinds of infestations due to gaps and cracks in the exterior walls. If animals have moved in, you may notice telltale signs such as animal fur and droppings, as well as pieces of fibreglass both indoors and outdoors. If this is the case, it’s important to replace the insulation and contact a pest control specialist.

5. Excess Insulation

Too much insulation in your home can affect its energy efficiency. It can be expensive, environmentally unfriendly, and increase the chances of mould growth. Extra insulation does not help reduce energy bills, and common signs of too much insulation include high electric bills, chilly drafts, and uneven heating or cooling. To fix the issue, you should identify areas with too much insulation, remove them, and replace them with more suitable materials.

Making the wrong decision when insulating your home can be costly. Avoid using new insulation on top of existing material when attempting this job yourself. An experienced contractor should be hired to remove the old and properly install the new insulation to ensure the job is done the first time correctly. This will help your home become more energy efficient and reduce heating and cooling costs.


Insulation is crucial to any home’s construction and can significantly affect energy efficiency and overall comfort. Unfortunately, a variety of common insulation problems can arise in a home, ranging from improper installation to water or pest damage. Homeowners can identify and address issues quickly and efficiently by understanding the five most common insulation problems and their solutions. With the right attention and care, insulation can help keep a home comfortable and energy efficient for years to come.
