The estimator gives you a price range based on the most common iFOAM projects in your area. For most homes the range you see will be within 10 to 15 percent of your final quoted price. The exact figure is confirmed at your free in home energy assessment, where your local iFOAM team measures the space, tests for air leaks and insulation gaps, and prepares a detailed proposal. Pricing varies between iFOAM locations because of local labor and material costs, which is why the estimator asks for your zip code and routes you to the right local team.
