"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."

"Fibers Insulation was extremely professional right from the first call. I chose their service from Angie’s Lust and within minutes Geovany responded. He came out on a Saturday to provide a quote and followed up days later. Members of the company were here at the designated time and did a stellar job! I insulated my garage to add better barrier for my garage to enhance a new AC unit to offset summer heat. Geovany followed up after the installation to ensure all went well. To ensure a better look, taping will be added to keep it looking great. I will recommend them to others in my gated community as I am very pleased with the result."

"IIS is an excellent company to complete your attic project. Alex initially gave me a free inspection and good estimate then made sure all my questions were answered throughout the whole project. All the work was done within a day and it was great pricing for the work performed, beats most competitors."

"Good company to work with! They were very nice and seem to be honest over the phone as well. They came on time and did the job. My A/C system didn't work good and a strange smell came out of the ducts when I turned the A/C on. 
Jose that did the work, checked everything and connected a machine to the system letting it run for a while and added a cleaning chemical that made this smell gone.
I will hire them for the future. it was a hassle free with this company.

"Zohar at Best Builders Group came out to our house in order to check and see how and what to change in the existing kitchen. Zohar and his team of people did a wonderful remodeling job from A to Z. We were very impressed and surprised from the high quality of the work and from the professionalism of the workers. During the work, several issues came up during the remodeling project but the team and Zohar handled all of them with no effect to the completion date and with no additional cost. We are looking forward to hire them soon and to remodel all of our bathrooms."

Insulation questions, answered by experts

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.

Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems.
