"I was notified by my water bureau that I had a major pipe leak and was horrified to learn that the leak added up to 10,000 gallons more than my normal usage in a billing cycle. I contacted Anton Beslic at MasterWorks Plumbing based on the stellar Angi reviews. He came over the following morning and diagnosed the problem within minutes: an old and cracked PVC pipe leading from the house to the meter. Anton made the arrangements to get the job started and mostly completed the following day. That involved getting a permit from the city; having officials mark on my lawn where fiber optic cables, gas lines, etc., were located; hiring a company to bore a new service line from the meter to the house crawl space; installing a quality 60’ pipe that will last way beyond my lifetime; installing an expansion tank on the water heater; and arranging for a final inspection from the city. Anton also installed a main house shut off in the closet next to the crawl space entry, which I did not have previously. I was so impressed by his professionalism, skill, and attention to detail and am forever grateful for how quickly he got the job done. I highly recommend MasterWorks plumbing!"

Percolation testing services FAQs

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.

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.

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.
