"Cornelio set an appointment the next day when I messaged to fix two faucets in our bathroom. He made a free inspection, gave us a very reasonable quote, and offered to work on the fix the same day. He explained to us how the cartridge in the faucets are clean and unclogged, but the faucet body from the cheap brand is clogged and not serviceable. He recommended replacement faucets that should last longer and serviceable. We appreciated his honesty and would ask for his service again!"

"Wilmar Plumbing was very responsive and empathetic towards my situation. They had to fix a problem caused by the previous plumber who installed my shower/tub drain incorrectly. I couldn't shower due to the leak. They treated my case like the emergency it was and Wilmar and his team showed up first thing. They fixed it diligently. They were so good, I hired them to install new bathroom sinks. These guys are great!"

Drain Cleaning questions, answered by experts

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.

Your sewer line can get grimy quickly. To prevent sludge buildup in your sewer line, pour a mixture of 1/3 cup of vinegar and 1/3 cup of baking soda down each drain in your home once a month. After about 30 minutes, flush the drain with hot water.

Some plumbers recommend 3/4 cup of bleach instead to clean any germs and bacteria that may build up in your sewer line. But this won’t break down any active clogs, and it cannot be combined with vinegar, as the mixture will create a toxic, hazardous gas.

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.

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.

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.
