"Andrew and his Crew from Roseburg were wonderful. They were able to get into our crawl space and did an amazing job clearing it out, installing drainage, a layer of plastic and sump pump. They left the area so much cleaner than it was when they arrived and they explained everything to us clearly so we would know what to do. We recommend them highly and it was a pleasure to meet them."

French Drains 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. 

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

Yes—your local septic company can clean your septic leach lines with a sewer jetter, a device that pumps high-pressure water through the lines to blast out any clogs and scum buildup. Unless there’s a clog or blockage in the lines, however, you do not need to perform this maintenance regularly. Do not attempt to clean your own leach lines, as you could easily damage them, leading to very costly repairs.

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.
