Home Insulation Pricing FAQ

How much does attic insulation cost?

Adding blown-in insulation to bring an attic to R-38 runs $1,500–$3,500 for most homes. The project typically pays for itself in 3–5 years through energy savings. Many utilities offer rebates that reduce payback period further.

What's the best type of insulation for a home?

Spray foam has the highest R-value and air-sealing properties but costs 3–5x more than fiberglass batt. Blown-in cellulose or fiberglass is the most cost-effective for attics. The best choice depends on location (attic vs. walls vs. crawl space).

Does adding insulation require a permit?

Adding insulation without structural changes typically doesn't require a permit. Spray foam applications may require ventilation inspections in some jurisdictions. Adding insulation to a new conditioned space (finishing a basement) usually requires a permit.
