When Should You Replace Blown-In Attic Insulation?
The short answer is that blown-in attic insulation should be replaced every 20 years or so. That said, there are a few factors that will affect the lifespan of this type of insulation and when it needs to be replaced.
For example, if your home is located in an area with extreme weather conditions (e.g., high humidity or extremely hot summers), then the insulation might not last as long as it would in a more temperate climate.
Additionally, if your attic has experienced water damage or rodent infestations at any point during its lifetime, then you may need to replace the insulation sooner than expected due to contamination from mold or other contaminants.
Signs Your Blown In Insulation Needs To Be Replaced
There are several signs you should look out for that indicate itโs time to replace your blown-in attic insulation. Here are just a few:
Uneven Temperatures
If certain parts of your home feel significantly warmer or colder than others despite similar settings on your thermostat, then this could be an indication that your existing insulation isnโt doing its job properly anymore and needs replacing.
Increasing Energy Bills
If youโve noticed an uptick in energy costs even though you havenโt made any significant changes to how much energy you use around the house, then this could mean that your existing attic insulation isnโt doing its job as well as it used to and needs replacing soon.
Visible Damage
If you can visibly see any damage (e.g., holes) in the existing blown-in attic insulation, then this likely means that there are air leaks in other areas as well and thus warrants a full replacement of all existing material to ensure optimal efficiency levels again.
