If your drains are slow, clogging repeatedly, gurgling, backing up, or giving off a foul odor, that usually means the blockage has moved beyond a simple surface fix. These symptoms often point to grease, hair, sludge, mineral buildup, or tree roots collecting deeper in the line, sometimes deep enough that a plunger or store-bought cleaner can’t reach it. Liberty Drain & Sewer inspects the system, pinpoints the actual cause, and recommends the drain-cleaning method that fits the problem, not a generic fix.
