You can assess if your home insulation needs replacement by observing signs like increased energy bills, uneven indoor temperatures, drafts, and visible damage to insulation materials. Additionally, if your insulation is over 10-15 years old or has been exposed to moisture or pests, it may require replacement.
In most homes, loose-fill insulation can survive anywhere from 80 to 100 years before needing replacement, provided that it is not damaged.

The cost to insulate a 2000-square-foot house can range from $2,000 to $6,000, depending on the type of insulation used and other factors.
Replacement and Removal
Insulation removal costs range from $1 to $2 per square foot. That comes out to around $1,000 to $2,000 if your attic is 1,000 sq. ft. The total cost for having old insulation removed and new insulation installed in your attic is about $2 to $8.50 per square foot.
Common Lifespans of Different Attic Insulation
Natural materials will inevitably degrade faster than synthetics, and some high grade synthetic materials can last virtually indefinitely if well taken care of. Fiberglass Insulation--The actual lifespan of this commonly used attic insulation is from 80-100 years.
Remove the outlet cover and shine a flashlight into the crack around the outlet box. You should be able to see if there is insulation in the wall and possibly how thick it is. Pull out a small amount of insulation if needed to help determine the type of insulation.
It is possible to over-insulate your house so much that it can't breathe. The whole point of home insulation is to tightly seal your home's interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers. That's when mold starts to grow.
Do I Have To Remove Old Insulation? Unless your insulation is wet, moldy or infested with pests, you don't need to remove it before adding insulation on top of it. ENERGY STAR® recommends that you inspect your insulation for signs of mold, mildew, moisture and pest infiltration before making this determination.
Best Time of Year to Buy Insulation
In this case, the spring is the best time, because you will also start to see savings in the summer months. The same is true for warmer climates, just different times of year because you'll want the job finished before the heat sets in.
The average U.S. homeowner spends about $1,852 to install insulation. Depending on the type of insulation, square footage, site location, and material, you might spend anywhere from $498 to $4,500. Insulation can keep your home cozy and warm on long winter nights or cool and comfortable on hot sunny days.
However, insulation can start falling from fiberglass batts after 15 to 20 years, so if your insulation was installed in batts well over a decade ago, it might be time for an inspection or a home energy audit.
The short answer is yes, upgrading insulation can increase the resale value of a home.
Here are some common insulation materials and their approximate costs per square foot: Fiberglass Batts or Rolls: $0.40 to $1.20 per square foot. Cellulose Insulation: $0.50 to $1.50 per square foot. Spray Foam Insulation: $1.50 to $3.50 per square foot.
How heat escapes from your home. If you're asking yourself Why is my house so cold even with the heating on? or Why is my house not staying warm?, the truth is that air leaks—along with insufficient insulation—cause heat to escape directly from your home.
Your home's walls and ceilings are cold to the touch
This is an easy way to spot the need for new insulation. Simply touch your walls and ceilings, and if they are cold, you need new insulation.
Check Behind the Baseboards
Put the wood between the wall and the pry bar to avoid any drywall damage. Then you can easily pry the trim away to get access to the bottom of the wall. If there is existing insulation like fiberglass or cellulose, you will be able to see it in the gap at the bottom of the drywall.
Choosing thermal curtains can help to reduce heat transfer on the coldest days of the year. Add a ductless HVAC system. A ductless HVAC, also called a split system, allows for supplemental heating and cooling where you need it. Maintain your HVAC system.
In reality, fiberglass insulation (whether batts, rolls, or blown-in) is very long-lasting. Under ideal conditions, it can insulate a home for 80–100 years. However, it is worth checking the quality and efficiency of the insulation at the 15- to 20-year mark.
Fiberglass insulation is constructed of tiny shards of glass that form pockets to trap air and help restrict the transfer of heat. Its naturally mold resistant in that the material itself is not a food source for mold.
So, how long does insulation take to install? Every house is unique, so the time to install foam insulation may vary. Generally, the removal and installation usually take two days.
