Ahern Gross Plumbing Contractors Reviews

★ 5★ 4★ 3★ 2★ 1I've had Ahern out twice. Once for installing a water filtration system. The guy did a great job. Then again today when I was woken up to water raining from my dining room ceiling. They got someone out within a couple hours since everyone was out at jobs at the time I called. The guys was great. Got everything taken care of and was very pleasant to work with. They are absolutely my go to plumbers!
March 07 · Victoria BourgoineI contacted Ahern to replace a shower nozzle for one bathroom. I had them arrive as promised and the plumber completed this request in 20 minutes and was leaving my home when I called and asked him to replace the other shower nozzle not on his work order. He stated he would have to swing by the office less than 2 miles away. He did so and returned in under 20 minutes. Then exactly 19 mins later he left my home. I thanked him for his quick service doing everything in under 1 hour. Fast forward to getting the bill. $376 is the demand for 1 hour 30 minutes. I called to complain about the overbilling as he entered my home @ 8:35 am and left at 9:35 am and should only be charged for 1 hour. This shady operation tried to tell me I should pay 54.00 extra for labor as he had to travel to my home and that is when the labor charge started. Then he says to dispute it however you want. I'll refer it to collections if you don't pay and hung up on me. I'm not done talking so I called back. They let it ring for 10 or more times hoping I would give up. Finally, Mike answers the phone. Mike claims he overheard the previous conversation and he stands behind the previous rep's comments claiming this is how we've done it for 40 years. Mike quickly becomes very rude and says "In what world do think it should all fall within 1 hour if you had the plumber leave and return?" I said in a world where you bill by the hour and give me 20 minutes. I told Mike he was crazy if he thought I would send a check for the full amount less our disputed amount of 54 + tax. Mike responded with "your clearly the one who is not in their right mind and has no idea of how plumbers work". You'll just pay it or I'll put you collections. I hung up on Mike telling him to f-ck off. It's a sad world when customer service is dead and people feel the need to steal from customers and overbill. This could have been resolved properly but instead, they hired poor employees.
October 07 · Matthew ThomasThese guys are great. I’ve had them at my place on two different occasions now. Honest work at a fair price. These guys came in 1,700$ cheaper than the competition for the same exact job, equipment, and materials. No attempts at upselling the job. I won’t be calling anyone else from here on out.Hats off to Ahern 🫵🫡
March 01 · Anthony GHad a water heater put in today and always a great experience with Ahern Gross. The gentleman that came to the house was very polite and punctual , had other work done in the past from them and will continue to use them for all our plumbing needs. Thank you guys!
February 29 · Eddie FischerWas able to schedule a appointment. Cleared my upstairs bathroom drain. Was amazed someone actually answered the phone. Seems everyone else in town won't pick up their calls. Did a great job. Even cleaned up.
