"We are so glad we found Bo's Insulation. We are very pleased with the job they completed today on our attic insulation. From salesman Nyc to the installers James and Abe and office coordinator Sydney everyone was polite, professional and very knowledgeable. They attend classes on insulation, sealing and energy efficiency and it shows in their work. They walked us through the OG&E Rebate. We highly recommend Bo's Insulation. Here's to saving on our gas and electric bills!"

"Our project to insulate our home turned out to be the best investment and most pleasant home project. It has been 3 months since the project and we have reduced our electric bill more than 50%. Jesse with Weatherization Experts explained insulation, the project and gave us a quote. He made sure the project went perfectly and the crew was amazing. They did a great job but were very kind, respectful and paid attention to keep the property clean and not track anything through the house. I honestly cannot say enough good things about this company. They are top notch and we will be contacting them in the future for all of our home weatherization needs."

"My installer was very knowledgeable and professional. His team promptly installed the insulation and baffles, as I requested, and tried to clean up afterward. I was already sweeping the garage, so I declined. The cost was exactly as quoted. Would be nice if they made it an option to pay online. (Maybe thatâ s possible now.) There was an immediate improvement in the comfort in the home. I would highly recommend this company."

"I would highly recommend Energy Efficient insulation. They are a family ran business with fantastic customer service open communication and just all around very good people. I had a unique job request in insulation a cargo van for a camper conversion and Brent was very helpful in walking me through the pros and cons of each option. The work performed was top notch, and I wouldnâ t hesitate to use them again for future insulation jobs and needs."

"Can't say enough good about this company. They were very quick to respond to my inquiry and the owner continued to maintain that same level of contact throughout the entire project. In my experience in dealing with contractors this is a rare and admirable quality. It is also indicative of their entire business mantra. I would not hesitate to use them again and definitely recommend them if you are looking for a competent and professional insulation company."

"A lot of people recommended that we just do blown insulation because spray was expensive. After receiving many quotes from a variety of companies I chose Alpa Omega Insulation. The owner came out and was very honest and personable and his quote was reasonable compared to the other companies. During the work I had no problems contacting him whether it was via text or phone call, he always answered and returned my phone calls. During any construction you run into problems that push back the next step and I called him several times to reschedule due to last minute issues and he was always pleasant and professional and never had an issue. I can not say enough highly praised words for this company! I would highly recommend them to anyone who needs any insulation work done!"

Insulation questions, answered by experts

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

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.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

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.
