"I purchased a home that was built in 1969. The insulation looked to be the original roll type insulation and was completely worn out. Derek Watt of Capstone Insulation came to my home and performed an inspection of the attic space. He made a video of his inspection and sat down with me to review his findings (loose AC connections, ceiling openings that needed to be sealed with foam, cam lights etc). Derek's price to do my job was less than other estimates Within couple of days, the job was done. Derek and his crew performed an air pressure check of the home's interior before and after completing the job. What a difference in the measurements before and after. I highly recommend Capstone Insulation for your insulation needs. They are professional, courteous, and on-time. Oh, and they also clean up their mess."

"Fair price an on-time service. But I should have checked the job..... there were a few spots in the attic that did not get any insulation. (not the garage..... that does not need insulation..... but a few spots over heated space were not covered). But their price was better than other estimates. I also requested the chemical that detracts rats and mice..... I do not know if it was included...... I hope so."

"Deli Brothers Insulation came to my home and did an absolutely marvelous job from start to finish. From the moment they arrived, their professionalism was clear—they were punctual, polite, and ready to get to work. Not only did they complete the insulation quickly and efficiently, but they also kept the work area spotless, which I really appreciated. Their team was extremely knowledgeable, answering all of my questions and explaining the process so I felt informed every step of the way. It’s rare to find a company that delivers both top-quality workmanship and outstanding customer service, but Deli Brothers Insulation truly exceeded my expectations. I would highly recommend them to anyone looking for reliable, clean, and expert insulation services."

Insulation questions, answered by experts

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.
