"Jacob Smyth was very cordial, honest, and he knew his profession well. His crew was polite and they did an excellent job on the new sewer line! They cleaned everything up, reconnected the chain link fence and protected the yard with plywood. I m so glad I hired them and will definitely recommend them if anyone needs them."

"Jason Dodge did a great job. Not only did he snake the drain in no time at all but he noticed the hot and cold water were reversed on my sink faucet and in 3 minutes he corrected it no charge! He couldn't have been nicer. I was only charged $100. for the whole thing. they have definitely become my go-to plumber!"

"Jared did great, very professional and knowledgeable, showed up on time, gave me several no pressure options, cleared up several questions and assumptions I had, performed efficiently on the option I chose, snaked our pipes about 75 feet several times, showed me the clog(s) he encountered, reassembled and flushed the system, and then had me run the washer drain cycle to make sure the sink gurgle was gone. Also pointed out an anomaly with the subfloor sink drain and explained how it should be. Great encounter, would definitely have Jared back if more service needed."

Drain Cleaning FAQs, answered by experts

If you leave liquid drain cleaner for too long, it will start breaking down your drainpipes. The chemicals in these cleaners can cause cracks, corrosion, and leaks in your pipes. They can also damage plumbing fixtures and even cause environmental damage if left too long without rinsing away.

Drain pipes carry wastewater from sinks, toilets, showers, and other fixtures to the main sewer line. They’re typically located within the walls and floors and beneath a home’s foundation. Meanwhile, sewer pipes transport collected wastewater to a septic tank or a municipal sewer system.

You can pour hot water down your gutter drain to melt ice and keep ice dams from forming. If the problems persist, consider investing in heat cables to run in your gutters. Heat cables can adjust based on the surrounding temperature to keep ice thawed.

The cost varies from $150 to $600, depending on the severity of the clog, pipe access, and required equipment.

Several signs can tip you off to a clogged dishwasher drain. At first, you may notice that it’s taking longer than usual for the dishwasher to drain, or you may hear gurgling sounds during the draining part of the cycle. You might also notice water backing up into your sink or excess food at the bottom of the dishwasher after a load. The most obvious sign, though, is seeing standing water at the bottom of your dishwasher after the cycle has finished.
