Len The Plumber, LLC. is a leading plumbing and drain company serving New Jersey. Our certified professional plumbers are available same day to assist residential customers in Burlington County and Camden County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!

"Did not go well at all with Len the Plumber was over charged and feel scammed, Len the Plumber, Technician Len Feldman started approx. 12pm until 3pm most of time going over the cost, taking pictures and finding everything possible that needed to be done and presented 10-page contract. Len Feldman (Technican) assessed the problem that was a leaking outside faucet that he explained froze over the winter and needed to be replaced. While water was leaking he did not turn off the inside valve and requested to have water company (Trenton Water Works) come out and turn off water by the main water line. TWW came out several times but could not find the line and sent out a third construction worker to locate the water line. Meantime Len left his personal contact # and promised to return as soon as the main water line was shut off. When Water Works returned on 6/25 could not reach Len, but was able to locate the main water line Len finally called back and said it would be ok he would be able to turn the water off was currently in Mays Landing that is approx. 65 miles away and could not return 6/25 but would be at my home to complete the job 6/26 am. After 9am no call no Len, I called again several times when finally able to reach him at around 9:30am, said he spoke to Supervisor and could not do anything until the main water line was completely shut off. I called Len the Plumber office spoke to Office Manager Cathy#610-616-3377 she said would try to get someone out asap, by later in the afternoon no return call from Cathy. At this point and 2 days later for an emergency it was time to find another Plumber and I cancelled everything at Len the Plumber. The Plumber came out Friday 6/27 completed the entire job within 1 hour, turned off the inside valve connected to the outside leak immediately as well as water to install the same job Len the Plumber contracted to do that, Len said would take at least 6 hours. Main Water Line never had to be touched!!! I am appalled with Len the Plumber that I could trust thru Angi's List with a good reliable repetition. This company had no consideration about leaving me and my family including my 88-year-old handicapped mother without running water for days, all he was concerned about was how much commission he could make off someone in a vulnerable situation."

Plumbing, HVAC, and electrical systems make your house livable. One minor issue with any of these systems can put your home at a standstill. In case you find yourself in this unfortunate situation, know that you can count on Gold Medal Service.

"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!"

FAQs for septic system installation and replacement projects in Pennington, NJ

Most septic system replacements require several days to complete, not including permitting and preparation time. The process begins with site assessment and testing, followed by excavation, component installation, and final inspection. Weather conditions, property accessibility, and inspection schedules can all affect your project timeline. Your contractor can provide a more specific estimate based on your property's unique characteristics.

Standard homeowners' insurance policies don't cover septic system replacement due to age or normal deterioration. Coverage may apply if damage results from specific covered events, but routine maintenance and eventual replacement are generally considered homeowner responsibilities. Review your policy details or speak with your insurance agent to understand your specific coverage limitations.

Look for multiple indicators such as slow-draining fixtures, unusual gurgling sounds in plumbing, sewage odors inside or outside your home, or wet spots in your yard. Unusually lush grass over the drain field area, frequent backups, or recurring repair needs might signal system failure. Addressing these warning signs promptly can prevent property damage and health hazards.

DIY septic installation is not recommended and may violate local regulations. Professional installation ensures compliance with health codes, proper design for your specific site conditions, and appropriate safety measures. The specialized equipment, technical knowledge, and permitting requirements make this a job best left to licensed professionals who can guarantee the system's safety and effectiveness.

With proper maintenance, including regular pumping, a drain field lasts 20 years. Various factors influence system longevity, including household size, water usage patterns, and soil conditions. Regular professional inspections can help determine when replacement becomes necessary. If your system requires increasingly frequent repairs, replacement might be more economical than continuing to address individual problems.
