FAQs for percolation testing projects in Portola Valley, CA

The average cost to snake your main sewer line is around $250 for a simple snake. Most sewer line specialists charge between $45 and $200 per hour for main sewer line snaking, so the time involved plays a major role. The price you’ll pay will depend on the severity of the clog, the item causing the backup, how long it takes to remove the item, and more. A more severe issue that requires unclogging a main sewer line will cost $3,100 on average.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100.

However, repairing septic lines costs more, averaging around $1,500.

The average cost to unclog a drain is around $200, with prices ranging between $110 and $800, depending on the type of drain and the extent of the clog. Hiring a professional to snake the toilet or sink will usually cost between $110 and $275, a bathtub or shower typically costs around $225, and a main line clog can cost between $100 and $800 based on the severity of the clog and how far beyond the access point the clog sits. Since the labor involved varies, most plumbers will charge an hourly rate for drain cleaning.
