A burst supply line, a water heater dumping onto the garage floor, or a sewer backup at 11pm doesn't wait for business hours. Emergency plumbing covers the calls that can't be scheduled a week out: burst or frozen pipes, active leaks, no hot water, sewage backups, gas line concerns, and clogged main lines that flood a bathroom or kitchen. We've got 8 businesses in Irmo that handle this kind of work, and picking the right one under pressure is harder than it sounds.
The main things to check before you're actually in a crisis: does the company have someone answering the phone at 2am (not just a voicemail), do they quote a trip charge or diagnostic fee upfront, are they licensed and insured in South Carolina, and can they actually get a truck to Irmo within an hour or two rather than just claiming 24/7 service. Ask about after-hours rates too, since emergency callouts almost always cost more than a daytime appointment.
Our scores weigh how consistently a company shows up when it says it will, how clearly they communicate pricing before starting work, and how customers describe the actual repair, not just the phone call. For the full rundown on how we build these rankings, see our methodology.
