What Affects the Price

  • Project Size and Square Footage : Larger projects typically cost less per square foot due to economies of scale. A 500 sq ft attic will have a different per-unit cost than a 2,000 sq ft installation.
  • Foam Type (Closed Cell vs. Open Cell) : 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.
  • Accessibility and Site Conditions : Difficult-to-reach areas, existing insulation removal, or complex roof structures may increase labor time and overall project cost.
  • Existing Insulation and Preparation : If old insulation must be removed before new foam is applied, this adds to the project scope. Removal services start at $950, and full replacement packages begin at $2,800.

Pricing FAQ

Why do spray foam insulation prices vary so much?
Several factors influence cost: project size, foam type (closed cell costs more but offers higher R-value), labor complexity, whether existing insulation needs removal, and site accessibility. A small rim joist project ($650 starting) is very different from a full attic renovation ($1.50/sq ft). We provide detailed quotes so you understand exactly what you're paying for.
What's the difference between closed cell and open cell foam, and which is cheaper?
Open cell foam starts at $0.55/board ft and is ideal for interior walls and attics where moisture isn't a concern. Closed cell foam begins at $1.20/board ft and offers superior R-value, moisture resistance, and structural support, making it better for crawl spaces, basements, and exterior applications. Your specific needs will determine which is the better investment.
How much does it cost to insulate a typical attic in Wausau?
Attic spray foam insulation starts at $1.50/sq ft. A 1,000 sq ft attic would begin around $1,500, but the final cost depends on current conditions, foam type, and whether removal of old insulation is needed. Call (534) 901-1691 for a free estimate tailored to your home.
Do you offer free estimates?
Yes. For residential projects like attics, crawl spaces, and air sealing, we provide free estimates. Commercial and new construction projects also receive free estimates. Contact us at (534) 901-1691 to schedule yours.
What if I need old insulation removed before the new foam is installed?
Insulation removal starts at $950, and full removal plus replacement begins at $2,800. This is often necessary to ensure proper application and to address any moisture or pest issues in the existing space. We'll assess your situation during the estimate and include removal costs in your final quote.
Are there financing options available?
We recommend discussing payment options directly with our team at (534) 901-1691. Many homeowners find that the energy savings from spray foam insulation offset the upfront investment over time, and we're happy to work with you on your specific budget.
