If you’re budgeting a structured wiring installation in St. Louis, most projects run $1,212-$6,062, 1% above the $2,800 national average.

Easiest place to save: Run cable during any renovation that opens walls - adding ethernet when drywall is already off costs 50-70% less than retrofitting later.
In the Midwest (where St. Louis sits): Competitive low-voltage market; older homes may need more complex retrofit work due to older framing styles.
