How much does it cost to replace insulation?

Insulation is made to last a long time; however, occasionally it may need to be replaced.

Reflective insulation can become torn and lose its efficiency, as the barrier is broken. On the other hand, bulk insulation can compress and lose its ability to absorb heat. If you’ve recently moved into an older home, you may also want to think about replacing the insulation to ensure you are getting the best thermal protection during the colder months. So, how much does it cost to replace insulation? Let’s break it down.


To replace insulation in an existing home, access is needed to remove the pre-existing insulation or to clean the space before the new insulation is installed. There are two areas of a home that can be replaced; the roof and the underfloor. Both areas need to be cleaned thoroughly before the insulation can be replaced. You may choose to do this yourself, but we recommend a professional. A professional insulation remover will remove any old insulation and make sure the area is safe to install new insulation. The cost of this varies depending on the size of the home and the area that is being removed.


Depending on where you live and the size of your home, the new insulation will vary in cost. You will need to look at factors such as r-value and the square metres of the area. A single bag of insulation with a coverage area of 15m2 will cost you as little as $60.00 Inc. GST. If you are planning on making this a DIY project, you will need to make sure you’re also buying protective gear to keep yourself safe from dust and other particles in the air.


This type of gear includes safety glasses, gloves, and a mask. Alternatively, you can get professionals to install the insulation for you. The cost of replacing insulation via professionals will be an all-inclusive cost, so you will have peace of mind knowing that your home will be insulated correctly and safely.
