Retrofit Measures for Unfinished Basement

Here you will find the data for Unfinished Basement measures available in the National Residential Efficiency Measures Database. Each measure consists of a before-component, an after-component, and the estimated cost to implement the measure. The measures are listed alphabetically based upon the name of the before-component. Where multiple costs are indicated they must be combined to obtain total measure cost (e.g., fixed ($) and normalized ($/sf) costs).

Cost Drivers

There are many factors that influence the ultimate cost of Unfinished Basement measures. The application of the average measure costs displayed below to any particular home is discouraged. Examples of the kinds of issues that can influence the cost of Unfinished Basement measures include:
  • Prevailing local wages
  • Drive time
  • Local code requirements
  • Access
  • Presence/condition/type of existing insulation
  • Existing construction and materials
  • Moisture issues present
  • Presence of hazardous materials
  • Extent of preparation
  • Accommodation for termite inspections
