Yes, and honestly, the small stuff is where they save you the most money. A running toilet or a dripping shower valve feels like something to put off, but that drip is usually a worn cartridge that takes twenty minutes to swap. Left alone, the same problems turn into water damage behind a wall or a wasted few hundred gallons a month. Licensed plumbers handle both ends of the range because the diagnostic work is the same either way — find the actual cause, not the symptom.

On the major side, it's repipes, sewer line replacement, water heater installs, and slab leaks. That work needs permits, pressure testing, and someone who'll stand behind it. A good Plumber Repair Service in Durham, NC does the small repairs and the big jobs, so you're not hunting for a new company when it escalates. My cousin had a water heater fail and flood part of his garage, called Drain Express, and they replaced it the next morning. He said the quote held and the crew cleaned up after themselves. He's passed their name to a few coworkers since.
