"Called GPS to explain what was going on after having the line snaked and plunged 2 different times from a previous company. Previous company did find a lodged object in the line. They told us we needed to dig up the sewer line, cut the pipe, remove the object and then repair. Max from GPS was here for five minutes when he thought to dig up some of our grass to look for a trap by the street. Which he found immediately ! Took him 2 more minutes to use a tool to grab a sippy cup that my son must have thrown down the drain on the side of the house. So thankful he thought to look for that trap. It not only saved me money and time, but gave me great relief that my plumbing is going to go back to normal again. All the girls who work in the office were extremely helpful as well ! Highly recommend Max and GPS and will be using them for all of our plumbing needs in the future. If anyone ever needs a plumber I'm recommending GPS. Thank you Max !!"

"I called the number. The person confirmed the appointment. The plumber was at the location at the precise time, inspected. Called me for the expected expense, we agreed over the phone. He got paid via Visa card and did the job. All done so professionally. Can't get better. I think he was little high in price but because its 5 degree F outside, its OK for one job."

"I received exceptional service from 2 Guys Plumbing and heating, marked by technicians who were punctual, courteous, and efficient, effectively addressing all my concerns, which resulted in extreme satisfaction and a high recommendation. We even had them come back to put in new toilets, new pipes in laundry room, add utility sink, and fix outside faucet. Wish I had known about them sooner!

FAQs for plumbing projects in Williamstown, NJ

Schedule a plumbing inspection every one to two years to ensure your system is in good working order. Regular inspections can help you catch minor issues before they become costly problems, like major water damage repairs. You should also consider a plumbing inspection when buying or selling a home or if you notice signs of a plumbing issue. Staying proactive with maintenance can save you money and stress in the long run.

A plumbing inspection for a standard one-story to two-story home takes between two and three hours. For larger residences, historic homes, or rental complexes, a complete inspection requires a full-day commitment of eight hours. However, this does not account for any necessary repairs that your plumber might find, so it’s best to set aside additional time during the inspection in case an unexpected repair comes up.

When built with quality materials, your plumbing system endures for decades. CPVC, brass, iron, and steel provide reliable service for 50 to 70 years, while copper extends durability up to 100 years, and PEX maintains performance for 80 to 100 years. Maintaining this system with regular inspections and prompt repairs guarantees long-term efficiency.

You should repipe your home when your plumbing exceeds its expected lifespan or uses hazardous materials like lead, polybutylene, or galvanized steel. Persistent leaks, corrosion, and compromised water quality signal that your existing piping no longer meets safety standards. Repiping eliminates potential health risks and prevents extensive water damage.
