"Well, the was too much on the second floor but Aladdin solved that with blown insulation. I look forward to the cool savings in the summer and warm savings in the winter. The house has not added insulation since it’s manufacture in 1989. We have been here for 4 years. Should have done it four years ago. Thank you Aladdin!"

"One of the best experiences we've had with work done in our home. Zac and the team from Foam Co went above and beyond for our project - removing the old insulation from our attic and installing new insulation. They arrived exactly at the agreed on time, took care to protect our home from any mess or damage, and completed the entire project in just a few short hours. All of the team members were polite and kind. They went above and beyond to clean up at the end of the project and to make sure we were satisfied with their work. We will absolutely hire them again in the future!"

"I chose Carico Drywall because of his attention to detail, the fact he came out to give me an estimate, and the fact that he uses Union Drywall Installers. He was my 3rd bid in my buildout for my garage, and he was the highest bid by far. But the fact that he came to my house, met with me, explained and asked good genuine questions proved to me that he was the correct person to do the job. My garage is 1500sqft (30 ft deep , 50 ft wide) ceiling height is 18ft. At the peak, its roughly 22ft. I used R21 batting in the walls and 6 to 7 inches of open cell spray foam in the ceiling. The shop was drywalled with 5/16 inch drywall, no real need for anything thicker since the insulation keeps most sound dampened. I didnt tackle the drywall, because I felt like that would have taken me forever. Would i recommend Carico to do more projects? Yes I would."

Insulation questions, answered by experts

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.

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.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.

A radiant barrier is a form of insulation topped with a reflective material designed to keep homes cool during hotter months. It is generally considered worth the investment if you live in a hot, sunny climate, as the cost can be recouped over time through lower energy bills. Installation costs typically range from $0.10 to $1 per square foot. After installation, homeowners in warm climates may save between $7 and $15 per month, potentially reducing their electric bill by 5% to 10%. The exact savings will vary depending on your location and the type of barrier chosen.

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.
