What Affects the Price
- Project Size and Square Footage : Larger projects typically cost less per square foot due to economies of scale. Attics, wall cavities, and metal buildings are priced by area, while smaller jobs like rim joists have fixed base costs.
- Foam Type Selection : Closed cell foam ($1.20/board ft) provides superior R-value and moisture resistance, while open cell foam ($0.55/board ft) is a cost-effective option for interior applications where moisture isn't a concern.
- Site Accessibility and Complexity : Difficult attic access, tight crawl spaces, or homes with existing insulation requiring removal will affect labor time and final pricing. We assess accessibility during your free estimate.
- Existing Insulation Removal : If your home has old insulation that needs removal before new foam installation, this adds to the project cost. Removal services start at $950, and replacement packages begin at $2,800.
