Insulation additions and replacements across different areas and material systems.
The Census category is “Insulation” within “Interior Additions and Replacements.” Different project sizes, specifications and amounts of work contribute to the median. The survey does not hold those features constant.
Use it beside a written scope
Which surfaces, removal, access and air-sealing tasks are included?
A difference between this figure and your quote does not by itself make the quote high or low. Separate material quantities, removal, preparation, access and excluded work before comparing contractors.
Then use your project budget worksheet to keep actual prices and unresolved work separate.
