sorry, i cannot give them -0 rating...my home wrnty.company sent them out for my water heater..total protect authorized the replacement but cnj plumbing would only do the job for an additional $425.00 for labor .they said they would only do it by replacing the shut off valve,new electrical bonding/grounding,t/p change over and new water lines,,,i contacted another plumbing company who installed my new heater which i purchased, and used all my exhisting connections as they were in good condition..they installed it for $85.00 ..it took them 1/2 hour start to finish...cnj thought they had me over a barrel..how is this company still in business..i wish i had read the reviews prior to the home warranty company sending them out...really...trying to over charge a homeowner $425.00.
