"Andy and his team did an excellent job of air sealing and insulating the knee walls (no insulation) and attic (poorly insulated) of our 100 year-old house. Because of the dormers, the knee wall insulation had to be done through four cutouts through the plaster walls. We are very happy with the results."

"I wouldnâ t go near anyone else for insulation. Andrewâ s price was much lower and his expertise much higher. Andrew spray-foamed our ~4,000-square-foot home. His bid came in some $5,000 less than competitors, partly because as he convincingly showed me, other insulators are typically spraying far more than needed. I also did not want to spray directly on our 1880s-era wood siding or sheathing as spray foam is notorious for trapping moisture and leading to rot in wood. But he figured out a solution to create a 1-inch air gap behind the spray foam to allow that wood siding to dry out when moist. He also knew other insulation options and really with that above solution, I think we ended up with the best possible insulation for our historic house. I can tell his business is going to do very well in Ohio Valley & Pittsburgh area and wish him the best moving forward."

"Dealing with Casey Insulation was great. They installed attic and garage insulation at my daughterâ s home in one day, and were meticulous in protecting exposed areas and in cleaning up, even though there was little to no mess. Owner Bob Casey is hands-on in the process, even stopping by on the install day to check the work. His son, Sean, explained the process and showed me the attic results when finished, which I appreciated. I highly recommend this company for anyoneâ s home insulation needs."

"The office staff was very good at scheduling and the estimation, prompt, efficient and great to deal with. The staff who had to come to do some prep work and the staff who did the insulating were on time and worked well until the job was completed. The price was also less than two other estimates. Over all, on every aspect of the job, we would give Mincin 5 STARS. Thank You."

"Bob and his team were great. Bob gave honest advice on the best option to insulate my attic and crawl spaces. The main issue we had was our infants bedroom which had brick walls and 2 windows making it very drafty. While the insulation made a noticeable difference overall, our sons room was still a bit drafty which we expected due to the brick outer walls. Still worth every penny."

"The job was extremely difficult due to three different layers of insulation in my attic including blown in insulation. They suggested I go with the foam. I requested they not spend to much time cleaning up because I wanted to clean the entire garage."

"I called to get a quote on the removal and installation for insulation in my attic. Erik Bachman was our Home Performance Specialist and was incredibly knowledgeable and honest with the quality of our existing insulation. As new home owners, the investment of installing new insulation can be overwhelming. Erik was very thorough in his inspection and was easy to talk to about what would make most sense in terms of an investment for our home. When the time is right, we will definitely give Insulwise a call for service. I am impressed with the high-level of customer service. I am relieved knowing that there is a local trust worthy company that I can call in the coming months to get the job done."

Insulation FAQs, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

A radiant barrier is a form of insulation topped with a reflective material designed to keep homes cool during hotter months. It is generally considered worth the investment if you live in a hot, sunny climate, as the cost can be recouped over time through lower energy bills. Installation costs typically range from $0.10 to $1 per square foot. After installation, homeowners in warm climates may save between $7 and $15 per month, potentially reducing their electric bill by 5% to 10%. The exact savings will vary depending on your location and the type of barrier chosen.

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

Durable materials suited for climate include aluminum for coastal areas or composite wood in varying environments for durability and minimal upkeep.
