Why the Insulation Growth Score exists
Most insulation contractors who want to grow assume they need more leads. Sometimes that is true. Often the real constraint is somewhere else: leads that are not followed up fast enough, estimates that do not close, or not enough crew to take on more work.
Spencer Hart built the Insulation Growth Score so owners get a straight answer about where their next bit of growth will come from. It tells you plainly when more marketing is not your problem.

How the score works
- Takes about three minutes, one question at a time, mostly multiple choice.
- You get an overall score out of 100 and a score for each of the six categories.
- Your biggest growth constraints are ranked by impact, with a recommended 90-day focus.
- Results show on screen and arrive by email. No sales call is required.
- It is free, and you can retake it as often as you want to track progress.
