"The insulation was installed as promised on the appropriate date, we are satisfied with the insulation. The problem was the work crew was extremely careless. There was foam insulation over the front door, front windows, they have to take off your siding in different areas, I am still picking up hundreds of screws. Foam insulation is still being picked up in my front mulch. Tarps were supposed to be laid and were not put down. My basement was another problem, it is finished with the Dow Corning type system, again, tarps were not used. There is foam insulation in three different areas that do not come off the cloth walls. When we started to point out these issues, they seem very concerned. The crew came back out and power washed the front of my house. The foam did not come off. They used our water for their power washer, left it running which created an ice dam in our back yard. On several occasions, we have tried to get some form of compensation for the basement and they are always looking into it; We are satisfied with the insulation, but everything was such a mess it was not worth it. I would look at other companies."

Insulation FAQs, answered by experts

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.

Buying a house with vermiculite insulation is not recommended without going through a proper testing process. Vermiculite insulation can potentially contain asbestos, which poses health risks when disturbed. While it is possible to purchase a home with vermiculite insulation, you should have it tested for asbestos, and ensure proper containment if asbestos is present. If asbestos is present, you will want to hire a professional to remove it, ideally before you move in.

Experts use advanced techniques and tools to assess existing insulation levels and identify gaps. They implement strategic placement of new insulation to ensure complete coverage, optimizing thermal resistance and energy efficiency.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.
