It’s a grind to run this kind of business. You’re sometimes dealing with life and death situations (you’re liable for someone’s electricity or heating 24/7). Talent is really hard to come by at a reasonable rate, especially reliable master electricians or plumbers and the trades people that work under them. And then it’s an extremely cost and labor intensive business involving large machinery, equipment, and vehicles - inside people’s homes. (Watched my dad scale one of these businesses for 30+ years, his work was stressful and unending)
