Plumbing has a consistent mix of emergency demand (burst pipes, major drain clogs, water heater failures) and project-based demand (remodels, fixture upgrades, water line replacements) that produces reliable call volume year-round. Emergency calls close at 50%+ when answered and responded to quickly. Project calls take slightly longer but carry higher average values.
