From leaks to breaks to clogs, there are a number of things that might cause the need to repair your bathroom sink. Bathroom sink drains are often out sight and out of mind – until they stop working. One minute, you’re brushing your teeth or washing your hands, and the water is flowing seamlessly. And then, all of a sudden, the water is filling your sink and it’s time to go to work. There’s nothing quite like the panic of a clogged drain or leaky bathroom sink.
