If you’re planning to install spray foam insulation in your attic, it’s essential to remove any existing insulation. This is because old insulation can compromise the effectiveness of the new spray foam insulation. This article will discuss insulation removal pros at Stellrr Insulation & Spray Foam and why old insulation needs to be removed before installing spray foam, and provide some tips on doing it. Below is why:
Old Insulation Can Become Wet And Moldy
One of the main reasons old insulation needs to be removed before installing spray foam is that it can become wet and moldy. When this happens, the insulation will lose its effectiveness, but it can also pose a health risk to you and your family. Mold spores can cause several adverse health effects, including respiratory problems, headaches, and skin irritation. So if you have any old insulation in your attic that’s wet or moldy, it’s essential to remove it immediately.
Old Insulation Can Reduce The Efficiency Of New Spray Foam Insulation
Another reason why old insulation needs to be removed before spray foam is that it can reduce the efficiency of the new insulation. When you have a layer of old, wet insulation between the new insulation and the roof deck, it will decrease the effectiveness of the new insulation. This is because the old insulation will act as an insulator and prevent the new insulation from working correctly. As a result, your attic will not be as well-insulated as possible, and you’ll waste money on the new insulation.
Old Insulation Can Contain Asbestos
If your home was built before 1980, there’s a good chance that the insulation in your attic contains asbestos. Asbestos is a harmful substance that can cause cancer and other serious health problems. If you have any old insulation in your attic that you suspect might contain asbestos, it must be tested by a professional. If it does contain asbestos, you’ll need to have it removed by a qualified contractor before installing the new spray foam insulation.
Old Insulation Can Be Difficult To Remove
Removing old insulation can be a time-consuming and challenging task. If you’re not familiar with the process, it’s best to hire a professional to do it for you. When hiring a professional, look for:
A licensed and insured company: Make sure that the company you hire is licensed and insured. That will protect you in the event of an accident or injury.
A company that has experience removing old insulation: It’s essential to choose a company that has experience removing it. This way, you can know that they know what they’re doing and will do a good job.
Ask the company about their experience removing old insulation before hiring them: This is very important, as not all companies have experience with this.
They should have insurance: As mentioned before, the company needs to have insurance in case of an accident.

Once you’ve removed the old insulation, installing new insulation immediately is essential. That will help prevent mold formation and ensure that your attic is adequately insulated.
