A blocked sink can be a nuisance at best and a hazard at worst. If you notice any of the following symptoms, it's likely that your sink is blocked:

• Slow draining or standing water in the sink
• Gurgling sounds coming from the drain
• Foul smells or sewage odours
• Overflowing or leaking water from the sink or pipes
• Wet spots or water damage around the sink or cabinet

These symptoms can be caused by a variety of factors, including food waste, grease, hair, soap scum, mineral build-up, foreign objects, or even tree roots infiltrating the pipes. If left untreated, a blocked sink can escalate into a bigger problem, such as a burst pipe, flooding, or sewage backup. That's why it's important to address it as soon as possible.
