"Abraham and his team, Will and Josh, did a great job of removing old insulation, sealing air leaks and adding new insulation to the attic in my 46 year old home. The old insulation was blocking air flow through the attic and this needed to be addressed, which they did. They were very professional and hard-working. Communication was excellent and everything was well explained and the process photographed. We are glad we hired Abraham for this project!"

"Prevailing came in to insulate my basement and attic. The workers were professional and worked the entire time they were here (which seems like a low standard, but I've had situations where 4 people come to work and 2 stand around talking for most of it from other companies). More importantly, they explained what they were doing as they did it, and cleaned up after themselves before they left! Scheduling the service was quick and easy since they were able to use our Alliant Energy quote to avoid a second home assessment, and they came in under budget. Very satisfied - plan to have them back to blow insulation in the exterior walls before winter."

"The installers were careful, courteous, & thorough. They left the premises clean & uncluttered. I can't wait to see the difference in our heating bill. They installed spray foam in the rim joist, a small ceiling in the basement & the walls in a crawl space."

"Abraham and his team were a fantastic help. Their service was life changing for our family. We live in a 120 year old home that had almost no insulation in the walls. Our HVAC could never keep up on cold, windy days. The last 3 winters there were times we had to go stay elsewhere as the home was too cold. Fast forward to this winter, after they completed the work we saw an immediate return. Bills went down and the home is comfortable. Heck there were times our HVAC stopped since it was so warm! They were very professional and worked around our hectic schedule. I would fully recommend them to anyone in need of insulation services."

Insulation questions, answered by experts

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

Yes, you can install insulation behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you’re looking to add insulation, it’s better to hire a professional, as you’ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.

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.

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

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.
