Attic Insulation

According to the Department of Energy, heating and cooling account for 50 to 70% of the energy used in the average American home. Additionally, inadequate attic insulation and air leakage are leading causes of energy waste in most homes.

The amount of energy you conserve depends on several factors: your local climate; the size, shape, and construction of your house; your family’s living habits; the type and efficiency of the heating and cooling systems; and the fuel you use. Once the energy savings have paid for the installation cost, energy conserved is money saved—and saving energy will be even more important as utility rates continue to increase. The insulation experts at Mr. Attic can help ensure that your attic is insulated properly. We’ve been helping families in Walnut Creek, Concord, Danville, Lafayette, San Ramon, Oakland, Berkeley, Martinez, San Rafael, and Antioch save money and be more comfortable in their homes for over 10 years.

Advantages of Insulating

  • Saves you money and saves our nation’s limited energy resources

  • Makes your house more comfortable by helping to maintain a uniform temperature throughout the house
  • Makes walls, ceilings, and floors warmer in the winter and cooler in the summer

Unbeatable R-Value

In terms of insulation, different materials and products used on and inside your home is given an R-value. This is a value that determines the level insulation per inch used. Poly spray foam has been proven to have a higher R-value than any other insulation material, with an R value of 6.2 or higher.

Natural Air Sealant

Where your insulation is concerned, you want something that will create both a barrier against air while providing insulation. Spray foam gets into all the nooks and crannies of the space it fills so that there will be no drafts or gaps. It does such a great job that it is often used as a super adhesive in spot applications to keep air from getting in or out of attics or crawl spaces.

Waterproof Properties

One of the greatest things about polyurethane spray foam is that it is extremely waterproof. While other types of insulation may get soaked through when in contact with moisture, spray foam repels water. It is also nonporous so that it will never soak up any moisture.

Foolproof Material

If you have a space that has a gap of even 5% of the total area to be insulated, this can diminish your insulation performance by about 50%! One of the benefits of closed-cell polyurethane spray foam is that it expands as it sprays, eliminating the possibility of a void or energy loss.


Depending on when your home was built and whether or not energy efficiency was taken into consideration at the time, you might want to consider upgrading it to a type that is more efficient. Call us today to schedule a free insulation evaluation.


Have you inspected your attic insulation, only to find it moldy, rotting, or destroyed by rodents? There’s no need to stress. We have over ten years of experience removing insulation from homes. We’ll get rid of the mess in no time.


Once we’ve removed any spoiled insulation from your attic, we’ll walk you through the various insulation options we offer and find the best fit for your home and needs. Then we’ll get you up and running with new insulation.


An insulation’s resistance to heat flow is measured or rated in terms of its thermal resistance, or R-value.  The more heat flow resistance your insulation provides, the higher your R-value and the lower your cost to heat or cool your home will be.

To determine whether you should add insulation, you first need to find out how much insulation you already have in your home and where.  If you live in a newer house, you can probably find out this information from the builder. If you live in an older house, you’ll need to inspect the insulation yourself or give us a call for a free insulation evaluation.

Determining Recommended R-Values
Once you know the R-value of your existing insulation, you can use the U.S. Department of Energy’s Zip Code Insulation Calculator to determine how much insulation you should add and where in order to achieve the recommended insulation levels for maximum energy efficiency.
