"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."

"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."

"While out of town, got word basement might be flooded. Called Schede to check boiler and hot water heater.. They went out the same day. Discovered sump pump wasn't working so replaced it. Cost pump and labor $800. Over the years they have responded to many problems, leaking faucets and stuck drains. Biggest project replace boiler for steam heat. Took 5 guys to wrestle boiler down a narrow basement stairway. Patient with a few family disagreements. Nothing to do with them. Installation successful. They've always been prompt courteous and non judgemental when encountering crazy working conditions. Think they are great. Boiler and hot water heater were fine. They installed both."

Drain Cleaning FAQs, answered by experts

It’s sometimes difficult to distinguish a clog from a frozen drainpipe since ice technically causes a clog. If the temperature doesn’t tip you off, there are a few additional signs that your pipe is frozen. Look for condensation and frost around the pipes. Ice in pipes can cause a banging or clanking noise as opposed to a clog from a softer material.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

There are a few reasons your snake won’t go down the floor drain. One common reason is a large obstruction in the drain that is causing a blockage. You can remove any debris you see in the drain before trying to snake it. In addition, the snake might not be long enough to reach the clog, or it might be the wrong diameter. 

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

While some chemical drain cleaners with hydrochloric acid can dissolve hair, this method is not recommended as it can also destroy your plumbing pipes. A common DIY alternative is using baking soda and vinegar, which can help break down the clog but will not actually dissolve the hair. The best and safest method for clearing a hair clog is to remove it manually. You can use a drain snake, a straightened wire hanger with pliers to fish out the clog, or have a plumber use a professional auger for more severe blockages.
