"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

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

Clearing typically takes 1-2 hours, depending on the blockage size and location.

Start by pouring hot—but not boiling—water down the drain. The heat of the water may be enough to break down the clog. You can also try ½ cup of dish soap or 1 cup each of white vinegar and baking soda. If you choose a chemical unclogging product, ensure it’s appropriate for toilets to avoid damage.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.
