"I purchased a home that was built in 1969. The insulation looked to be the original roll type insulation and was completely worn out. Derek Watt of Capstone Insulation came to my home and performed an inspection of the attic space. He made a video of his inspection and sat down with me to review his findings (loose AC connections, ceiling openings that needed to be sealed with foam, cam lights etc). Derek's price to do my job was less than other estimates Within couple of days, the job was done. Derek and his crew performed an air pressure check of the home's interior before and after completing the job. What a difference in the measurements before and after. I highly recommend Capstone Insulation for your insulation needs. They are professional, courteous, and on-time. Oh, and they also clean up their mess."

"Fair price an on-time service. But I should have checked the job..... there were a few spots in the attic that did not get any insulation. (not the garage..... that does not need insulation..... but a few spots over heated space were not covered). But their price was better than other estimates. I also requested the chemical that detracts rats and mice..... I do not know if it was included...... I hope so."

"Deli Brothers Insulation came to my home and did an absolutely marvelous job from start to finish. From the moment they arrived, their professionalism was clear—they were punctual, polite, and ready to get to work. Not only did they complete the insulation quickly and efficiently, but they also kept the work area spotless, which I really appreciated. Their team was extremely knowledgeable, answering all of my questions and explaining the process so I felt informed every step of the way. It’s rare to find a company that delivers both top-quality workmanship and outstanding customer service, but Deli Brothers Insulation truly exceeded my expectations. I would highly recommend them to anyone looking for reliable, clean, and expert insulation services."

Insulation questions, answered by experts

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.
