  • Sealing and insulating floor headers
Low to mid level Can be DIY or

amount of labour.

Mid-Level: Interior and some exterior

Contractor, energy
advisor
Best approach - well
planned and
noticeable results

Major: Interior and Exterior

  • Remove all exterior finish, apply new air sealing & insulation
  • Remediation of toxic materials - lead, asbestos, etc..
  • Complete renovation for targeted performance
  • Gut interior back to framing, build out again
  • Is the structure worth saving? Consider building new.
  • Heritage structure?
