How we work

  • Measure first. No price until we have seen the building.
  • Say it plainly. If blown-in insulation is the better value for your home, we will tell you.
  • Write it down. Foam type, depth, square footage and price in the proposal.
  • Prove it. Readings and photos in the completion report.
  • Get the money facts right. We check rebates before we mention them, and we do not advertise tax credits that have ended.
