What red flags should I watch for hiring a window installer in Knoxville?
Check that any Knoxville contractor doing window replacement carries both general liability insurance ($1M minimum) and workers' compensation. Request certificates directly from the insurer, not just copies the contractor provides.

If they ask you to pull the permit, they may not be properly licensed to do the work.
