What commercial plumbing covers
Commercial plumbing deals with the systems behind restaurants, offices, retail spaces, apartment buildings, and municipal or industrial sites around Irmo. That's a different scope than a residential job: think grease trap maintenance for a Lake Murray-Blvd restaurant, backflow prevention testing for a strip mall, multi-unit water heater replacement at an apartment complex, or rerouting supply lines during a build-out on Main Street. The pipe sizing, code requirements, and permitting are heavier than a house call, and the crew needs to work around business hours or off-hours scheduling so a shop or restaurant doesn't lose a day of revenue.
What to check before hiring
Ask whether the contractor carries commercial general liability coverage and is licensed for the specific work (backflow testing and grease trap service often require separate certifications in South Carolina). Get a written scope with materials specified, not just a labor estimate, and ask how they handle emergencies like a burst line or sewer backup that can shut down a business. Response time and after-hours availability matter more here than in residential work, since downtime costs money.
