"In July 2024 I hired Insulation Labs to add more insulation to our attic. They showed up on time with a truck full of insulation, and a few hours later they had put all of it inside our attic. They did a good job up there. I am very pleased with how everything turned out. One thing that distinguished Insulation Labs from some other outfits is that they did not try to up-sell us with services we didnâ t need."

"After talking with several attic clean out and insulation, wall insulation companies, I decided to go with Marathon Insulation. Johnathan was very helpful and professional, gave the best choices for my issues, without trying to upsell like some of the others. After getting the attic and walls insulated (with attic clean out) I can already feel the heat stay in the rooms much longer and the walls much less cold to the touch before. I highly recommend Marathon Insulation! They were always on time, delivered as promised, and cleaned up after."

"I love the insulation. My room has no insulation at all. Every time I entered the room after coming from work, it was like walking in an oven. With the insulation, my room now is cool in the afternoon. The price Pro Insulation, Inc. charged is reasonable. I just love it. It is a good investment."

"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"After having a new air conditioning system installed, to replace an old inefficient one, we decided to make sure our attic had the correct insulation as well as the appropriate R-value. Since our home was built in the 1950's, the insulation throughout the attic was minimal. We hired Insulation Commandos to survey and provide us with the appropriate solution. The solution involved removal of the old insulation, cleaning the area, and installing the correct insulation based on our homes location. We now believe we can keep our energy costs down and provide less strain on our AC system. Great job team!"

"This business is great to work with! They showed up early and got right to work. They laid down protective plastic as we have blown insulation that gets everywhere. They installed attic and subfloor. I thought they would be here all day. They were down in about 3 hours. Quality work, professional and very informative and clean!"

Insulation questions, answered by experts

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

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.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

Yes, insulating hot water pipes helps your system run more efficiently. This is especially true in basements in colder climates, where cold air likes to settle in. There are a few ways to insulate water pipes (foam is common) to keep hot water hot, reducing the need for your water heater to constantly heat the water in the tank or your circulator to kick on more than necessary.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.
