Hairline cracks—tiny cracks in the surface—in porcelain sinks can happen due to age, chemical damage from cleaning products, dropping heavy objects on the sink, thermal shock from drastic temperature changes, stress during repairs, and manufacturing errors. Hairline cracks often start very small and grow longer and wider over time. While they may appear problematic, hairline cracks don’t indicate structural problems and may not impact the performance of sinks. However, they can eventually cause water leaks and mold growth if left to grow.

The cost to fix a leaky pipe ranges depending on location—the easier the pipe is to access, the less expensive the repair will be. Because a leaky pipe under the sink is typically an exposed pipe, this is one of the least expensive repairs for a plumber to do, often costing between $150 to $300 to fix, on average.

While the drain connection for a garbage disposal is nearly universal and fits standard sink drain holes of 3 1/2 to 4 inches, the size of the disposal unit itself is not. You must have enough space in the cabinet underneath your sink to accommodate the disposal's housing. A larger model may not fit in a compact cabinet or if the existing plumbing is arranged in an unusual way. Before buying a new garbage disposal, measure the available space under your sink. If you are replacing an old unit, it's often easiest to choose a new model of a similar size.

The average cost to hire a plumber is typically between $45 and $200 per hour, with a common average rate around $125 per hour. This cost can vary based on your location, the plumber's experience, and the complexity of the job. Rates are often broken down by experience level: an apprentice may charge $45 to $90 an hour, a journeyman $60 to $110 an hour, and a master plumber $80 to $200 an hour. While hourly rates are standard, some plumbers may charge a flat fee for routine projects or offer project-based pricing. It's also common for plumbers to charge a minimum service or trip fee. For reference, some typical flat-rate costs for common jobs include: drain unclogging ($220), leaky faucet repair ($270), burst pipe repair ($400), toilet repair ($300), and water heater repair ($600). Note that these rates are for standard service hours; emergency, holiday, and after-hours calls will cost significantly more.
