In case you find yourself in this unfortunate situation, know that you can count on Gold Medal Service. For over 24 years, our company has been taking care of the homes of New Jersey residents through our top quality plumbing, HVAC, and electrical services. We are available 24 hours a day, 7 days a week to address even the most mind-boggling issues of your in-home equipment. From repairs, installations, and upgrades, our technicians are known for getting the job done right every time.

"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

He was immediately able to identify the issue and suggest a corrective action. Jamie waited patiently as we spent time deciding if we wanted to follow his recommendation. All of my valves we leaking around the apartment so it was a chaotic afternoon after work and Jaime stayed absolutely calm, patient, and professional. He helped control the issue and suggest a solution to help maintain the situation overnight then came back and finished the job. Very responsive with great service and workmanship.

"We paid close to $20,000 to BQ Basements to completely waterproof our basement. We still get water and they told us we need another sump pump installed at over $2,000. They guaranteed we would not get water after installation. Be aware they do not stand behind their work or honor warranties."

Plumbing questions, answered by experts

Regular cleaning, avoiding grease disposal in sinks, and installing drain strainers help prevent clogs.

Annual inspection prevents leaks, blockages, pressure issues, or other problems from developing.

Old pipes can be damaged by hydro jetting due to the intense amount of pressure that travels through them. For PVC pipes, which are one of the most common materials used for sewer lines, it’s considered safe.

Capping a gas line costs approximately $125. The final price varies from $75 and $150 depending on your contractor’s hourly rate. To completely remove a gas line and cap it at the base can cost up to $250. Most contractors will charge a flat fee instead of by the hour since capping is often part of a larger project.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.
