"well there were delays but i forgive that. they did NOT get permits. a new hot water heater was brought and hooked up. But connections were loose and made it inoperable! its taken another plumber and an Electrician to fix what was wrong to actually get hot water. the original cost was $2500. Now add the $500 for 2nd plumber to reinstall the emergency shut off box that was installed improperly. AND an Electrician for $800 To fix the rest. They have not responded to email requesting attention. Technician was great - altho did not know everything necessary to complete my job. this has been a two week nightmare! i am NOT happy!"

Gold Medal Services, LLC, warrants and guarantees to the original purchaser, that should Customer accept and purchase Gold Medal's recommended repair, such repair shall be free from defect in materials and workmanship under normal use and conditions for as long as the Customer owns the residence in which the recommended repair was provided or until the Unit in which the Covered Repair was performed, if applicable, is replaced.

"Gold Medal really helped out after our sewer line backed up into our basement. The other pros all wanted us to pay for a camera view first for several hundred. Then the actual cleaning of the line was $500 and up depending on the results of the camera. Gold Medal had a fixed price for cleaning out a sewer line. They came and quickly diagnosed the problem and cleaned it out. Our technician Brett was awesome and even put us in touch with DryTech to assist cleaning up the water damage."

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."

Here at Zoom Drain, we are best known for fast response times and our ability to provide focused solutions to drain & sewer problems. If you are having issues or planning for future maintenance, call us now at 610-628-3360 for a FREE on-site estimate. From sinks, toilets and tubs to main lines and sewers, our team of drain & sewer professionals are ready to provide you with fast, expert services.

"They truly live by the code of "you get what you paid for". The price was cheaper than expected (and they included a free estimate too). So ultimately, our slow bathtub drain was cleared. However, the technician had terrible housekeeping. After stripping the caulking around the overflow valve, they left the caulking pieces in the bathtub and told us to flush them down the drain (?!). They said the provided bio solution would clear the pieces just fine...but why do that when a trash can is less than a foot away?? Then, they did not offer to reseal the valve they just opened...just left a mess for us to pick up. As such, we will not be using them again next time...free estimate or not. If we wanted the bare minimum, we would have done it ourselves."
