How Long Does it Take to Install Foam insulation? [Video]

Are you considering foam insulation for your home, but you’re wondering about how long the install process will take?

With more than 15 years of experience, RetroFoam of Michigan’s installation crews are a fine-tuned machine. Most houses can be insulated in one day or less. Probably two if we are insulating the attic, as the first day would be removal of old insulation.

Other Foam Insulation Installation Factors that Determine Time

The area that is being insulated and the degree of difficulty of the job are the two main factors associated with the length of install.

  • All existing external walls - Injecting foam insulation into existing walls could take 2 to 5 hours on average, depending on the size of the area, siding type, if the home is one or two stories, and any bumpouts in home design.
  • Attics - Insulating an attic could take one to two days. This depends on how much old insulation in the attics must be removed. A separate removal crew may come out a day or two before the installation date to remove the old insulation. Once the install crew is there, in most cases the attic can be insulated in a day. Factors on time include the pitch of the attic and accessibility difficulties to certain areas.
  • Crawl space - A crawl space installation can take 2 to 3 hours to do. Factors include if any old insulation needs to be removed and any accessibility challenges like hard to reach areas due to the design of the crawl space.
  • Rim Joist - Insulating a rim joist usually takes around 1 to 2 hours. If fiberglass needs to be removed, it may take a little longer. Also if the rim joist is hard to reach due to basement design or things in the way the install job could take longer.

Every house is unique, so times to install foam insulation may vary.
