He explained the situation clearly and outlined the necessary steps to resolve the clog. Despite the complexity of the issue, Jesse worked efficiently and effectively to restore normal function.

"Luke was a great help. Despite not being a typical install, Luke went the extra mile to clean our wood burning stove setup and gave us valuable knowledge for the future. Highly recommend, will be using him again for sure."

"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

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. 

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

Professional plumbers use many high-grade chemicals to unclog drains. Many use hydrochloric acid, known as muriatic acid, when it comes to extreme blockages. 

There are several ways to tell if your gutter downspout drain is backed up. The most obvious sign is when you see water flowing over your gutter edges. This can occur during everything from light rain to a rainstorm. Additional signs can include peeling paint around your downspout, visible dirt around your downspout, and moisture on the side of the house. If you're having ongoing problems with clogs caused by a poorly designed or worn-out gutter system, consider getting a quote for gutter replacement cost.

You may have a clogged gutter. Downspouts can also clog if your gutter collects too much debris. Hire a professional gutter cleaner, and if you still have problems, install a gutter guard (which prevents debris from entering your gutter system) and a downspout extension (which helps drain water further away from your foundation, so it doesn't pool near your house). Follow these tips to keep your gutter downspouts clean.
