"Very professional. Cleaned up everything no mess left behind. I thought my new sink that I had installed was clogged not draining right but ended up just being the stopper. He also put a plate around the pipe to make it look better."

"I can t say enough great things about Hosack Plumbing and Excavation. They just completed replacing the main water line from our home to the street. Their work is excellent, they completely explain what they are doing and make you feel very comfortable and when the work is completed everything is neat and clean and back to its original state. Their pricing was very fair and they were professional and friendly."

"the technician from zoom drain was great. He led me through the entire process, including clearing the clog, showing me with a camera the roots that caused the blockage in my sewer main, water jetting the line to remove the roots, and showing me the cleaned out line after he was done. 10/10 service."

"I want to thank Hosack Plumbing, and Kent, for getting my situation cleaned up quickly and professionally. My water heater install is perfect, my water pressure spot on thanks to the new PRV, and is ready for inspection. Kent was thorough, professional, and very clean. He noticed my mask when I answered the door and wore a kn95 mask the whole time. The life coaching advice was an added bonus. Kent's work was great and I'm very pleased with the service provided."

"Very prompt and professional. Exceeded my expectations. Would definitely recommend and hire again for any plumbing work."
On average, a plumber will take 30 minutes to two hours to clear a clogged drain. If the clog is located close to the drain or an access point and isn’t severe, the project will take about half an hour. If the clog is deep within your plumbing system or is a severe blockage, it can take two or more hours to remove the clog. For this reason, main line clogs tend to take longer, usually between two and three hours.
It’s possible to snake minor drain clogs yourself, provided they sit within a foot or two of the drain itself, but it’s usually best to hire a professional plumber regardless. Even experienced DIYers have a high chance of accidentally pushing the clog further into the drain using a drain snake or another tool, so hiring a plumber is the ideal course of action. A professional plumber can use camera equipment to locate and identify the clog, and remove the entire blockage to fix your issue permanently.
In most areas, drain cleaning professionals don’t technically need a license, as they aren’t altering your plumbing system in any way. However, we recommend hiring a drain cleaning professional with a plumbing license and certification. Certified plumbers are more likely to provide professional solutions to drain clogs without damaging your system. They’ll also have the diagnostic tools and experience necessary to remove the clog entirely rather than providing a temporary solution, as a handyperson might. Use Angi’s state licensing tool to check your plumber’s professional licenses before hiring.
Applying drain cleaner is a common DIY solution to clogged drains, but it can be extremely harmful to your pipes and lead to corrosion and leaks. It is almost always better to try snaking a clog than using a drain cleaner, but the best solution is to hire a professional plumber. They can locate the clog and gauge the severity using a camera system and then decide if using a plumber’s snake, auger, or drain cleaner is the best option to remove the clog and limit damage to your plumbing system.
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.
