"Knowledgeable, professional and courteous. Ralph (Master Licensed Plumber) and Peter (assistant plumber) fixed a PSEG Red Ticket issue (dirty gas burners were replaced with new ones)). Work was performed well explaining what was being done as they went along and clean up was very good."

"Needed leaky water valve repaired and sewer system unclogged. Came within 45 minutes of my desperate phone call. Installed new valve and new copper piping. Could not flush clog from inside, so came next day and dug 7' hole in front garden to remove the clog. Also installed vertical pipe to access any future sewer problems. Work crew had to dig out two big bushes to access the old sewer pipe at my home's foundation but replanted them along with any tulip bulbs they displaced. Truely considerate of my early spring garden! Courteous, mindful of property, work done in a timely fashion at a fair price. Explained each step in the process and why it was needful. Very pleased with 'Moose' and his work team."

"Amazing Service! My main sewer line backed up late last night, causing a huge mess and a lot of stress. Mo arrived within an hour. He was incredibly professional, quickly diagnosed the problem, and cleared the line promptly. Everything returned to normal quickly, and he cleaned up thoroughly before leaving. The speed and efficiency are appreciated.""

"I called Gashi Plumbing at 9 am after noticing water coming out the wall from my kitchen. I said it’s an emergency, he came just in time at 10:30 and explain to me everything. He did the job in less than 1:15 minutes which included some extra surprises after checking the pipes. Daniel was so professional and honest. The price was so fair. I just want to mention that he did not want to charge me on something that was not needed after checking something else in my bathroom. He just explained how it will be fixed by replacing the top piece. I am so happy that my call was answered and definitely keeping him for my future plumbing needs and I recommend him."

Sewer Cleaning FAQs, answered by experts

If used correctly and sparingly, root killer shouldn’t damage your pipes. Make sure to follow the instructions on the back of the bottle or the company’s website to avoid any unintended damages. However, when it comes to copper sulfate, it’s better to avoid it. This type of root killer can damage your plumbing and the surrounding environment.

Yes, hiring a drain cleaner is worth it, especially when compared to the cost of not being able to use a sink, shower, toilet, or bathtub and the potential damage that flooding can cause in your home. You might try a temporary drain cleaning liquid or snaking it yourself, but if the clog is out of reach or these methods do not work, then hiring a professional drain cleaner is the way to go.

There are several common signs that your main sewer line may be clogged. Key indicators include multiple fixtures in your home draining slowly, gurgling sounds coming from drains or toilets, and water backing up into showers, sinks, or toilets. You might also notice water backing up from the plumbing system's drain cleanout, water in your basement drain, or unexplained wet patches on your lawn. Foul odors, such as the smell of raw sewage or rotten eggs, are another common symptom. The most reliable way to confirm a main sewer line clog is to hire a professional plumber to perform a camera inspection.

A sewer cleanout typically looks like a white or gray PVC pipe with a removable cap. It's often located either in your yard or basement, depending on your home's plumbing configuration. The cleanout pipe is designed to provide easy access to your sewer system for maintenance and inspections. It may be flush with the ground or slightly elevated, making it distinguishable from other pipes. When you remove the cap, you can access the sewer line directly or determine its direction, which can be helpful when you need to locate your sewer line from your house to the street.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.
