"When we finally determined that our problem was clog in the drain pipe that was under a slab we were very concerned. I posted my problem on Home Advisor and got an immediate response from this company. Charlie was here on a Saturday within a couple of hours! He snaked about 50 ft. and the problem was solved within minutes! So grateful for solving this problem the weekend before Christmas! Price was reasonable for a weekend. I would recommend him for drain problems!"

Drain Cleaning FAQs, answered by experts

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.

A clogged air gap can cause a dishwasher not to drain. There are, however, other potential issues that can lead to improper drainage. For example, if you have attached the air gap to a garbage disposal and forgotten to remove the knockout plug, wastewater may backflow into the dishwasher. Check that the air gap is installed properly, and then look for clogs in the air gap and dishwasher filters. 

Yes, sewage smells can originate from a floor drain. If the P-Trap in the floor drain dries out or if there's a clog or other issue in the plumbing system, sewer gasses can escape through the drain, causing nasty odors. Regularly pouring water into the drain helps maintain the water seal and prevent those smells, but if the smell persists, you should have a plumbing professional inspect the drain for potential problems.

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.

Flushing the toilet only to realize it’s clogged can cause anxiety. To avoid a clogged toilet, use less toilet paper. If you notice that the toilet is flushing and refilling slower than usual, you can use a plunger to clear clogs in the S-trap. If that doesn’t work, call a plumber to check your system and possibly clear the drain lines.
