"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"I am remodeling my entire home from the foundation up and out of all the jobs I have hired out F.B.I. was by far my best investment. The quality of the work is outstanding, the customer service was amazing (I had a ton of questions about every aspect of the spray foam and they were very patient with me), and to top it off their price was the best around. My husband and I noticed how much better the house was holding heat the day they left. Amazing work. Next year when I put my Addition on I will be hiring them again."

"Everything was as promised and customer service worked with me to alleviate my concern of pre-payment. No complaints. I’d probably go to 5 stars except that I haven’t fully checked for changes in energy consumption to know if it was the right solution. I know that the price was significantly less than other quotes!"

Insulation FAQs, answered by experts

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.

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.

Generally, the cost of ice dam removal is not covered by homeowners insurance because it is often considered preventable maintenance. However, the damage caused by ice dams is frequently covered. Depending on your policy, this can include interior water damage, roof collapses, and damage to shingles. Coverage for personal belongings affected by leaks may vary. It is important to check your policy details or contact your insurer to confirm what your plan covers. Keep in mind that any damage resulting from a DIY attempt to remove an ice dam will likely not be covered.

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.
