Should I charge more for emergency or after-hours work?
Short answer
Yes. 1.5x to 2x your normal rate, no apology. Your nights and weekends are not normal pricing.
Why it's fair
You're trading family time, sleep, and a higher mistake rate. The customer calling at 11 PM has plenty of options at 9 AM and chose not to use them.
Be clear up front
Tell them the rate before you roll. 'Our after-hours rate is $X. Want me to come now or first thing tomorrow at regular rate?' Lets them choose, removes the bill-shock fight.
