"Had gurgling from 2 bathroom sinks. Not knowing if this was a concern, I reached out to Angie's List for quotes from plumbers. The first one to respond was ValDel Plumbing. They were able to schedule me in for the next day. Our plumber, Steve, arrived and diagnosed the problem - partially clogged sinks. He corrected the problem per the quote. While working on the sinks, he noted that the drain pipes connected to the p-trap should be modified (he did this at no extra cost). After the job was completed, I had a question about my sump pump. He offered to look at it and gave some recommendations. Overall, I felt that the job was corrected to my satisfaction. The work done by Steve was both personable and professional. If I had future plumbing needs, I would strongly consider ValDel Plumbing."

"It's hard to find good plumbers, and even harder to find good plumbers that are also honest and have reasonable prices, and A1 accomplishes that. I always pick up my own parts to save money, but some people I called for estimates wouldn't allow me to do that, and others seemed to be charging more for the installation to make up for the difference. Not only did A1 provide me with the location to purchase my new disposal for the best price, but they also charged a service fee flat rate for what was obviously a fairly simple job. I am now requesting estimates for other work at my home from them instead of my other companies."

""Jay" from ValDel Plumbing showed up exactly on time after I arranged appointment on short notice. The quoted price I thought was high. But, we agreed on a reasonable price. Our 3rd time using Val Del. I don't even bother calling others anymore. This time I had leaking fixtures from an old Water Softner. The unit was too heavy to remove. So, Jay had 2 DelVal workers come out at 8AM the next morning. They removed the heavy salt from the unit (messy back-breaking job, and removed unit, cleaned up. I would never call another plumber."

"After dealing with roto rooter and Losch plumbing with very bad experiences. Thank God for finding Once & Done. Very professional crew, they did a great job in installing the new sump pump that we definitely needed. Jeff was very honest and nice and explained everything that had to be done in detail. Highly recommend."

"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!"

French Drains FAQs, answered by experts

There are several homemade solutions for clearing a clogged sink that don’t involve pouring harsh chemicals down your drain. Start by pouring hot (but not boiling) water down the drain. This can help dissolve and flush away grease and gunk. A splash of dish soap down the drain can also cut through fat and make it easier to clear the drain. For a more stubborn blockage, grab a plunger and give it a few firm pumps to dislodge the clog.

The best drain cleaners are biodegradable ones or a mixture of baking soda and vinegar. Strong, caustic chemicals may seem appealing with promises of unclogging your drain quickly, but liquid drain cleaners can cause damage to your pipes over time. Consider making your own drain cleaner with baking soda and vinegar.

Costs vary by severity and access requirements. Typical pricing ranges from $100 to $350, increasing with complexity or for emergency services.

If your washing machine drain is clogged, that isn’t a good sign. Unlike toilet drains or kitchen sink drains, there isn’t matter that is easily broken up with a plumbing snake, and more care is required. If you’re in an old house or have mineral-rich water, there could be a buildup inside the pipe. Either way, if the blockage isn’t obvious and doesn’t dislodge with a snake, you need to call a pro—otherwise, you risk damaging integral plumbing.

The cost to clean a sewer line is about $370, ranging from about $190 to $550 on average. The specific cleaning method and the problem's severity will impact the project's overall cost. Some of the most common sewer line cleaning methods include:

  • Snaking or rodding: $100–$250

  • Hydrojetting: $350–$600

  • Chemical treatments: $600–$1,000

  • Repair or replacement: $1,000–$7,500
