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.

"Tony was very pleasant to work with. He accommodated my schedule, even with a big winter storm that had just rolled through. Tony and his team finished the project in about a day and a half and I couldn’t be more pleased! Not only was the job exactly what I needed/requested, but it was a very neat and clean job. His team respected my house and left the work area spotless. I will definitely call Tony if I ever need anything plumbing related."

"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."

"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

Drain Cleaning FAQs, answered by experts

Yes, hiring a drain cleaner is worth it, especially when compared to the cost of not being able to use a sink, shower, toilet, or bathtub and the potential damage that flooding can cause in your home. You might try a temporary drain cleaning liquid or snaking it yourself, but if the clog is out of reach or these methods do not work, then hiring a professional drain cleaner is the way to go.

You’ll likely pay between $300 and $450 to unclog your toilet with Roto-Rooter. However, the price could change depending on if the clog has caused a lot of damage, which your plumbing pro will want to inspect during your service appointment. Keep in mind that you won’t get a quote from Roto-Rooter over the phone. They have to send a pro out for an in-person cost estimate. You can also attempt to snake your own clog for a lot less, and simple drain snakes cost no more than $50.

If you leave liquid drain cleaner for too long, it will start breaking down your drainpipes. The chemicals in these cleaners can cause cracks, corrosion, and leaks in your pipes. They can also damage plumbing fixtures and even cause environmental damage if left too long without rinsing away.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

When you put baking soda and vinegar down the drain, they chemically react and help break down clogs. It’s not going to work for every type of clog, however. For example, it’s not the best way to get rid of grease buildup. For grease, you should try boiling water and white vinegar instead.
