"Having experienced trades people who do not show up on time or complete work, it was refreshing to find a company that offers excellent customer service. The needed work was scheduled for the next day. We were kept informed of the anticipated arrival time. Once at our home, we were apprised of what work would be required. John and Zack went above and beyond by helping us with an additional plumbing job after competely completing the needed repair. John also alerted us to a situation that, if left uncorrected, will be a costly repair. At no point did he pressure us or try to take advantage of the situation. We believe John was simply providing us with good service and at a reasonable cost. We also noticed John interacted with his employee, in a respectful manner. It was obvious to us that John was mentoring his employee and imparting his knowledge in a manner that reflected his pride in his chosen profession. We recommend Newburgh Plumbing without reservation and are happy to know that there are still trades people who care about the work they do and want to provide high quality services for their customers. Kudos to John, Zack and the woman who scheduled the appointment."

"I had a plumbing leak since February 2024 whereas the leak was coming from my bathroom shower leaking into my kitchen, when I immediately contacted my home warranty American Shield, they never provided me with a Plumbing contractor. From February 22, 2024 until March 24, 2024, I continued to have leakage. American Home Shield then told me they had no contractors to assist me with my plumbing issues and therefore wanted me to identify a Plumbing contractor and then submit the diagnosis to them for review and approval. I then identified Royal Class Service and they diagnosed the leakage as a Shower Valve Replacement whereas they would need to open drywall from the closet to gain access for repair. The estimate from Royal Class was over $2,000.00. American Home Sheild then sent PROSERVICE HVAC & PLUMBING for a second option located in Connecticut. They stated that Royal Class inflated the cost repair and this Pro-Service Company was supposed now take over the repairs. I waited three more weeks because when I called Pro-Service requesting a date for repair they continuously told me they are waiting for valve they ordered from Home Depot. They are the worse!!! I'm Disabled and was out of my shower usage for three months. Well on a Thursday of early May, I happen to see Neighborhood Plumbing truck and contacted Anthony (contractor). Anthony came to home so professional and concerned to assist me with the well overdue plumbing issue and Neighborhood Plumbing repaired this in less than two hours at a price that was extremely fair and far more less than Royal Class quoted and five star professional than American Home Sheild and Pro-Service located in Connecticut. Please don't get taken by these companies. Anthony could have attempted to inflate his prices and robbed me like Royal Class attempted or he could have never come back to repair just as Pro-Service did. But, Neighborhood Plumbing does not have professional integrity they get the job done at a cost that's not ROBBERY! I had a horrible experience with these former companies and I urge you to seek out Neighborhood Plumbing if you need Plumbing, Heating & Cooling Services. Thank you Neighborhood Plumbing,"

Sewer Cleaning FAQs, answered by experts

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

Roto-Rooter does not charge by the hour, so the quote you get after your in-person consultation should cover the whole project. This includes the time it takes a technician to get to your house and the time it takes to complete the job. For context, a plumber will charge anywhere from $45 to $200 per hour, but you may also pay a service fee or flat fee. 

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

A professional drain cleaner is a plumber or specialized drain cleaner with the necessary tools to unclog drains and tiles to keep waste water flowing out to the septic tank or city sewer for processing. Keeping wastewater from backing up into your home helps keep you and your family safe from potential contamination and sickness. These pros can help resolve nearly any drain situation in a safe and efficient manner.
