"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,"

"Expert Mechanical came and helped me in a stressful time. My leach field was improperly installed where it was only operating at 30% and it had to be replaced. After searching through many contractors we found Expert Mechanical LLC. Seth and his team installed a new leach system, french drain and redirected my gutter system. They did an outstanding job. Seth was professional, knowledgeable, reasonable, responsive and sympathetic to my situation. I highly recommend Expert Mechanical for any plumbing, Heating, and Septic repair. I would definitely use this company again if needed."

"Kevan (spelled with an "a") was the only plumber who even called me back the day after Christmas. All these other companies that advertise 24/7 & Holidays emergency service did not even answer the phone. We lost power and our pipes froze in super cold weather we had Christmas 2022. In 32 years my pipes never froze but they did this time and they burst in multiple locations. Kevin called and came out the same day and worked into the night replacing multiple ruptures. He is extremely courteous and professional and I HIGHLY RECOMMEND HIM for any plumbing or water treatment needs. Ken H., New Paltz, NY."

"1 & Done Plumbing has done an excellent job in finding and fixing the water leak(which a couple of other plumbers couldn't find)from the shower stall. Anthony and Andrew(the father and son duo) are honest and dedicated workers. I do not hesitate in seeking help from them again."

Affordable Plumbers FAQs, answered by experts

If the shut-off valve to your kitchen sink appears to be stuck or broken, there's no need to panic! The workaround is to turn off the main valve that supplies water to your entire household. This valve is located along the main water line. Of course, it's also important to have a plumber repair the malfunctioning shut-off valve under your kitchen sink because this indicates a problem.

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.

Anything you drop down your sink runs the risk of damaging and clogging your pipes. Hair, bits of food, and other debris can catch on the item and build up over time, causing a clog. Even if it’s not valuable, it’s definitely worth trying to retrieve the item, or at the very least, asking a pro for specific advice.

It is okay to use a drain auger on a toilet, just make sure you are using the correct tip size. The auger is a plumbing snake with a protective sleeve to protect the porcelain toilet bowl from getting scratched. Using too large of an auger can cause the snake to loop back and damage the inside of the drain and plumbing.

To keep your toilet in good working order, replace the toilet fill valve every five years. Toilets get quite a workout, so while toilet maintenance may not be on top of your to-do list, it’s essential to keep up with it to ensure your toilet is in good working order and ready when needed.
