How Long Does Home Insulation Last?

NexGen How Long Does Home Insulation Last

How long home insulation lasts depends on the material and various factors that can reduce its lifespan. Some materials hold up longer than others. Nonetheless, home insulation doesn’t last forever. If you have an older home or insulation that was installed decades ago, you should consult with a home insulation contractor. Here’s a closer look at how long it may last and when to consider replacing it.

Average Lifespan and Insulation Type

Every insulating material has its benefits and expected lifespan. Therefore, knowing the type of insulation in your home helps determine whether to look into replacing it. Here are some common insulating materials and their typical lifespans:

Signs It’s Time for New Home Insulation

Insulation is hidden in the walls, ceilings, and attic of your home. You can’t usually see it deteriorating, but there are signs that suggest it may be time to call a contractor to take a look. Here are some reasons to call:

The location of the signs you notice can point to where the problem is. For example, if your floors are cold, insulation in the crawl space may be sagging or breaking up. If your walls are cold to the touch or surfaces or dishes in kitchen cabinets are cold, have a contractor check the insulation in the exterior walls. Meanwhile, temperature control issues throughout your home or ice dams on your roof indicate an attic insulation problem, which allows warm air from the inside to escape.

Deteriorated insulation can create a wide range of issues. If you can see your home insulation (it’s typically most visible in the attic), it should look fluffy and uniform. Replace it if it’s saturated with moisture, full of mold, has shifted to one side or another, or if it’s formed a big pile in the middle.

What Causes Home Insulation to Deteriorate?

No matter the expected lifespan of an insulating material, it can deteriorate depending on the conditions. It will have to be replaced sooner if:

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.

Yesterday I had NexGen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, NexGen’s price was over $3,000 cheaper than all other competitors.

My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend NexGen.
