"The owner of the company Jason Taylor spent time in my attic before we contracted with them so he could give me good and correct information. He also participated in the work of shooting in the insulation. He was very hands-on. Donâ t usually expect this attention from the owner/boss Was very pleased."

"This company installed two whirlybird wind turbine on the roof. During the installation, one roof rafter was cut halfway with a saw blade. I thought the insulation process itself is excellent and am very happy with the result."

"Elliott and his team came out and did a great job! They removed our old insulation and installed new blown-in insulation. Not only is the house quieter and more comfortable, but we?ve noticed a big improvement in the overall indoor air quality. I really appreciated the fact that the crew was respectful of our home. They worked hard and got the project done in 1 day."

"Did a great job...it was a very long day from start to finish however. They did a great job of keeping everything as clean as they could since our attic access was in the master closet! Yikes! Really made a difference and our house stayed much cooler with the fan and new insulation!"

"Rafael and the Attic Advisor team were great! Rafael came out to do the free inspection and give us a quote. He was on time, friendly and very knowledgeable about the issues in our attic and what could be done to resolve them. The assessment and estimate were very in-depth, and the price was very reasonable and fair (compared to quotes I got from other companies for the same work). Even before committing to the project, Rafael was very responsive and would take time answer any question I had about the project. The project in my attic called for removing the old insulation, sanitizing, sealing to keep critters and rodents out, replacing old air ducts and installing new insulation. On the day of the project, the Attic Advisor crew was on time, hard working and extremely professional. They were very efficient and thorough, with even the smallest parts of the job, and if I had any questions during the process, they were very polite and happy to answer. I appreciated Attic Advisor’s thorough and complete work. I would highly recommend."

Insulation questions, answered by experts

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

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.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.
