"Blake Excavation was recommended and we are ever so grateful! Our Septic Drainfield had failed after 42 years and we were in need of urgent help. Despite delays courtesy of an understaffed DEQ Jason kept us informed and was onsite the minute the permit was approved. The crew showed up on Friday and worked through the weekend to get us back online. They were courteous and caring and we are ever so grateful!"

French Drains FAQs, answered by experts

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

In the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.

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.
