"I recently experienced a severe clogged sewer issue and reached out to Winners Sewer and Drain for help. Jesse arrived on time and conducted a comprehensive inspection to diagnose the problem. 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. I appreciated his transparency regarding the costs and the absence of any unexpected fees. Jesse not only resolved the issue promptly but also ensured minimal disruption to our daily activities. I highly recommend Winners Sewer and Drain for anyone facing similar plumbing challenges."

"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."

Drain Cleaning FAQs, answered by experts

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.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

Yes, many services include camera inspections to identify the cause of the blockage. Confirm with your provider.

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.
