"Fast, Clean, Efficient, Feasible! This is an easy review to write when you have a professional on the job. Titan Plumbing Sewer & Drain was on site ready to swap out our old tank and install the new one. Also, was aware of new housing codes and installed an Expansion Tank. He could of easily changed the thermocouple just to get by but did not recommend doing so on a 10+ unit. Do it right once and call Titan Plumbing Sewer & Drain. We were so happy with their service! Easy to recommend them"

"We have used Gene from Preferred Plumbing on several occasions. We had a water heater replaced and multiple faucets, hose bibs changed or repaired, and drain / sewer clogs. Gene was responsive, courteous, and explained the issue and required work clearly. The work was completed without issues and reasonably priced. I recommend Gene (Preferred Plumbing) for any plumbing issues / work."

"Moe from 123 Sewer and Drain is a great plumber. He showed up at the time he said he would. He assessed the problem which was a clogged 4"cast iron main pipe and charged a fair price. On top of being a great plumber, Moe is really nice guy. While he was unclogging the drain we talked a bit about some of the recent life challenges I'm facing. I was grateful for his empathy and kindness. Highly recommend Moe and 123 Sewer/Drain LLC."

"If I could give 10 STARS I would. I have been in Dumont for over 23 years and have used multiple Plumbers. My favorite plumber retired and I was left to look for a new company. As a single mom, its hard to find companies I can trust inside my home or actually do the job correctly. Well, All Pipeworks was perfect from beginning to end. Erik immediately contacted me to review my issues with my water heater. HE LOOKED up my warranty FOR ME... He took the time to call my water heater company, found my contract and my remaining warranty. He helped me with all my options and was never pushy or aggressive. He explained everything in a language I can understand and was absolutely professional. He and his team, came by replaced my water Heather and other items from my furnace. He left the place clean, did not damage anything else in the boiler room and I have hot water again. It was seamless from start to finish. I will be calling Eric again for all plumbing needs. THANKS ERIK :-)"

"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."

"I recently had plumbing work done and had the pleasure of working with Gashi. He was incredibly kind, respectful, and thoughtful throughout the entire process. Although the project turned out to be more extensive and needed to be escalated, Gashi handled his part with great professionalism and care. He took the time to explain things clearly and made sure everything was left tidy. I truly appreciated his friendly attitude and attention to detail. Highly recommend Gashi for anyone looking for reliable and considerate plumbing service."

Plumbing questions, answered by experts

You can buy a sealant spray for a leaking copper pipe, but it’s not a permanent solution and isn’t usually a good idea. For the best adhesion, you should drain the pipe, let it dry completely, apply the spray, and wait for it to dry before turning the water back on. Even with proper technique, a sealant spray is a temporary fix, so you should only use this technique in the interim to prevent water damage if you’re waiting for a more permanent fix.

Yes, most bathrooms can be converted into a wet room, but the process often involves extensive renovations. Key requirements include having proper plumbing and the ability to slope the floor slightly for drainage. The conversion process typically requires removing the existing floors to install drainage, replacing drywall with waterproofed cement backer board, waterproofing the walls, and installing new fixtures to create an open, curbless shower space. A skilled home renovation professional can evaluate your bathroom to determine if it's a suitable candidate. It's also worth considering resale value; if you only have one bathroom, converting it to a wet room might not be ideal as many homebuyers prefer to have at least one bathtub.

Many plumbers include removing and disposing of the old toilet as part of their service package. However, it’s best to ask before signing a contract, as removal isn’t guaranteed. If the plumber doesn’t take the old toilet, you have several options, including donation, recycling, junk removal, and bulk waste services..

Shower valve replacement costs an average of $350, and most homeowners pay between $150 and $550. The price will depend on labor costs in your area, as well as the type of diverter valve you choose. A simple diverter valve could cost just $20 in materials, while a high-end mixing valve for better temperature control can cost $350.

Yes, a skilled plumber can thaw frozen pipes, and it is recommended to hire a professional rather than attempting a DIY fix. A plumber will typically start by investigating your plumbing to locate the frozen areas. They then use professional equipment, such as a heat gun, to safely thaw the affected pipes. If a pipe has already burst or developed leaks, the plumber can make the necessary repairs. For homes with frequently frozen pipes, a plumber can also suggest preventative measures like improving pipe insulation or rerouting lines away from areas prone to freezing.
