"Justin is a true professional and his crew go above and beyond to complete the job. While spray foam insulation is not cheap I feel that the job I received will pay dividends years to come. Justin is deeply committed to his community and I work beside him every year as volunteers to build our ice palace before winter carnival. His ethics are shown thru this work and it translate into his business. Thank you. dave"

"R-Factor Insulation Company does very good work. They insulated my crawl space and did a wonderful job. The owner Mr. Knapp was very professional and came out and gave a free estimate on the work. The job estimate was right on the price with no cost over runs at the completion of the
job. I had other estimates that were much higher on the same work to be done."

Insulation FAQs, answered by experts

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

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

If you have blown-in insulation, using an insulation vacuum will quickly and easily suck up all the insulation. Many come with built-in HEPA filters for added safety. While some people suggest breaking up large batts and feeding them into the vacuum, this can expose you to more fiberglass fibers. With batts and rolls, carefully removing them and placing them into garbage bags is a better process.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.
