"I highly recommend this company for any type of insulation work. The salesman gave a very thorough presentation on all the available options for me, along with a rough estimate at the end of the meeting. I went with the option of removing & installing new rolled insulation (R30). The crew arrived on the scheduled installation date and got right to work. Sealed off everything properly, removed the old insulation, cleaned & cleared out the space, and then installed the new insulation. It was all completed in about 4 hours. I was very impressed."

"If anyone’s dealing with cold spots in their house — we just had our closet spray foam, and it made a huge difference. It was never insulated when we built, and now it’s finally warm. The crew was super professional, very neat, and honestly just a great group of guys. Highly recommend.!"

Insulation questions, answered by experts

It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.

Once installed, injection insulation requires little maintenance, but periodic inspections for air leaks or moisture buildup are recommended.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.
