"All Star was here within two hours of our call the day after Christmas, right when Brian said he would be here. Got it cleared right away, reasonably priced. Wiped the area under the sink with cleaner when he was finished."

"I worked with Jesse to help with a clogged bathtub drain after I tried plunging it myself. I explained over the phone that I was dealing with backflow problems and each time I used the bathroom sink the water would end up back in the tub. Unlike another plumber who said they would need to charge me to snake both the tub and the bathroom sink, Jesse explained it would likely just need to be the sink and there is an issue in the shared drainage pipe. Jesse communicated clearly when he'd arrive and on his availabilites, and helped resolve the issue quickly and cleaned up after himself. He also gave me additional advice on how to manage my drainage issues in the future, and another toilet problem I had. Good guy to work with, and got the job done. Would hire again."

"Lou and his technicians were great. They provided timely, accurate quotes and explained everything about improving our hot water service and all of our options. The technicians came on time for all appointments and were incredibly helpful. They explained everything to my wife and I, and were very helpful. We would hire them again for any plumbing needs."

Drain Cleaning FAQs, answered by experts

The best way to unclog a bathtub drain is to pour a pot of boiled water down the drain, being careful not to splash yourself. However, take precautions, as boiling water can damage PVC pipes and joints. Follow up with ½ cup of baking soda and ½ cup of vinegar. Cover the drain with a small sink plunger and let it sit for 15 minutes. Pour boiling water down the drain again and replace the drain stopper.

Your clothes—and your washing machine—will send you a few signals if you’re overdue for cleaning your washing machine filter. If you notice a buildup of detergent residue on your clothes, your clothes don’t dry quickly or at all, or you’re noticing lint in the machine, it’s time to clean the filter. 

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.
