No water to upstairs sink

Here is the problem and I have NO idea what is happening. I have an upstairs bathroom with a shower a sink and toilet. The shower and toilet work but when I turn the faucets on for the sink nothing comes out of either the hot or cold. Everything else in the house works why not that sink. I have not added anything or changed anything. The only thing done was the main water line that come in from the city was shut off outside our house for a few hours while they did some work on the street out front of our house. But they turned it back on and everything worked. Now no sink. Any help would be great. Thank you

Well you can check the supply lines step by step by turning off the valves under the sink and removing them from the faucet then turning them on and seeing if you have water flow and also this allows you to flush them out.

My take is that sediment somehow lodged in the supply valves under this one sink after the job was done on the water line.The sediment may be in or also be in the faucet itself which would require removing the stems and cleaning that area out.If you get water flow through the supplies and supply valves but not the faucet then the faucet has become clogged.

My theory is that sink was being used at a strategically bad time when sediment was drawn into it from the water line work.

If the hot water and cold water are both affected at a sink, the first thing to check to see if the aerator at the end of the faucet got plugged up.

If it does turn out to be the aerator,you should still flush out the faucet lines as enough grit to clog an aerator to total blockage will have left grit elsewhere.
