For unvented crawl spaces, insulating the walls and encapsulating the entire space is far more effective and qualifies for energy-efficiency improvements. Floor insulation is a lower-cost option but doesn't address moisture or air quality.

Crawl space insulation in Hudson and surrounding towns typically costs $2,000–$7,000 depending on size and accessibility. energy-efficiency improvements can significantly offset this cost.

Yes. Cold floors above uninsulated crawl spaces are a direct result of heat escaping through the floor assembly. Proper insulation and encapsulation typically eliminates the problem completely.
