Len The Plumber Heating & Air, LLC
Len The Plumber Heating & Air, LLC
Len The Plumber Heating & Air, 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."

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

"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!"
