"Suddenly, my basement drain was backing up! A friend tried to unclog it, but to know avail. He thought it might have something to do with the sewer line that ran to the street! Right away, I started seeing dollars signs. So, I went on Angie's list and saw the reviews for HL Bowman. Because they were so highly recommended, I went to their website. Immediately, there was a person named Tiera to chat with. I explained my situation and she asked me a few questions. She told me she would have some one call me. I asked if it would be today because there was sitting water in my basement and I was afraid to even flush a toilet! She said it would definitely be today! Within two minutes of concluding the chat, my phone rang. A very courteous person assured me that he could get someone out there today! It was about 8:30 am and he told me that he could have someone by this afternoon and they would call me before they arrived. Around noon, a young man named Clayton called and said he was on his way. When he arrived, he went to basement and checked out the situation. When he came up he said that he thought the clog was in the pipe along the wall going out to the sewer. He brought in a machine and spent approximately and hour and a half trying to open the clog. He then told me that he had called another person from the company to bring a larger machine. Then, Corey showed up with a huge machine and Clayton left to go to another job. Corey was down there for about another hour and half. The machine was much louder than the first one. I was really worried about the cost and the fact that it was taking so long to open. I pictured having to have my lawn torn up and imagining what that would entail, not to mention the cost. Suddenly, he appeared and I tried to prepare for the worst. He looked at me with a smile on his face and said, "it's open". I was so surprised, I am sure he saw the relief on my face. 'He explained that he had to go out 75 feet to the street, and the that the clog was because of tree roots which he grinded through. I knew this machine was probably more expensive to use than the smaller one. So I braced my self and I asked him what the total charge would be! When he told me, I was shocked as that even included the $70 service fee which included up to 45 minutes to diagnose the problem and give me an estimate. But, because Corey had to bring a bigger machine and stay longer than Clayton had estimated, I was sure it was going to be astronomical. Corey said he would figure it out! When he told me the price I could hardly believe my ears. It was half of what I had anticipated! I was thinking about $1,000- $1200! I can't begin to explain how relieved I was.. I would like to say both Clayton and Corey could not have been nicer. Very mannerly, friendly, and polite. When Corey left, everthing was cleaned up! No sewage anywhere. And another thing that I thought was extraordinary, was how unafraid they were of my two pittbulls. They petted them and Corey even told them to stay when they tried to follow him out the door. LOL! And they, listened! I have found my company should I need any future help. It's good to know that there is someone out there who is professional, knowledgeable, and who charges fair prices. It wasn't cheap, but I believe it could have been a lot higher. Family members also thought the price was good. It started out as a bad day, but I had a smile on my face when Corey left!"

Drain Cleaning FAQs, answered by experts

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

If you drop jewelry down your sink, it can cause a clog, especially if it accumulates other debris on its way down. However, that is the least of your worries if you drop your favorite jewelry down your drain. If your gold band goes tumbling down the sink drain, don’t panic—refrain from running more water down the sink, and follow the steps above.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

It’ll take 20 to 30 minutes to unclog a sewer line using a drain snake or drain cleaner. If you hire a professional, you should expect them to be on-site for three hours or less. In addition to clearing the clog, they’ll do other routine inspections, which adds to the overall time (and cost) required.

If your kitchen is flooding, first turn off the water supply and electricity before entering the room. Next, focus on immediate flood control by cleaning up any standing water with a sump pump or wet-dry vacuum to prevent long-term water damage to your home. Open your windows and run any dehumidifiers you have handy. Finally, call a professional plumber to help find the source of the flood and repair it.
