Recommended Customer Reviews

The most disgusting experience I've ever had EVER! Dude says he's going to head out to find a part for my water heater at 11a says he'll be back in an hour. By 1p I call him and he says he's going to different stores trying to get the part. 3pm,. 4pm comes and he stops answering my phone calls. At about 630p my insurance company calls and says he called early today to tell them GM doesn't work with my type of water heater! Spent the entire day waiting on the most unprofessional, lying person. Would never recommend hiring this company to my worst enemy!

MORRIS is the man!! Yep, I found GM plumbing thru YELP and all I read about was Morris ~ you want it done RIGHT, call this place ONLY. I had two other plumbers (supposedly) fix the problem, that sprang a leak AGAIN! Called ~ got Morris and that thing is GOOD TO GO! Oh and I got a 5 year guarantee, THIS TIME. Thanks very much Morris for ALL YOUR HELP (and he's very neat too!)

I called them to fix a water heater that wasn't working and that guy said that it was the thermocouple.he replaced it but obviously the part was used because didnt work .i kept calling the guy to come back and fix the problem to which he said he was going to stop by to fix the issue ,he never did.called him several times,all lies.unproffesional.

***A COMPANY YOU CAN TRUST*****
I had a sewer line completely clogged up by tree roots. My family couldn't use the toilets or anything else. Morris came out as promised on a Sunday afternoon and fixed the problem. But more importantly, he didn't charge me an ""arm & a leg"" for coming out on a Sunday and he could have done things I didn't need. He was reasonable and I felt like I wasn't getting ripped off!

To be honest we didn't actually use this service. One of our toilets is malfunctioning so we called AHS, our home warranty service for a service call. An appt. was set up with GM Plumbing and Sewer for 9 to 11 on Thurs. Yet on Wed. night I had a message on my machine saying that the technician had come by but no one was home. Left no number. So I looked up the number and called and was told that they got the dates wrong - they wanted to know if they could come out now - like 8PM?. That did not work for us so they said that someone would be out at the originally designated time, between 9 and 11, on Thurs. At 10:30 on Thurs someone called (could barely understand them cuz of static on their cell phone) and said they were running a little late. At 12:20 still no one had arrived or had even called to give an update. We had to go to work so we called AHS and canceled the service call. Very unprofessional.

Totally unprofessional. Convinced my elderly mother-n-law that she needed an additional $150 worth of work they did NOT perform. I would NOT ever consider hiring this company again.

Morris and team are great, very professional and thorough, gave an amazing deal and took care of our rental with care. They just won all my business:)

Very unhappy with the lack of professionalism and service. We had them out for our septic system because they were on our homeowners insurance list of contracted sewer technicians. We have been going back and forth with them for months trying to resolve our dissatisfaction with the poor service, seeming lack of knowledge, and unauthorized disposal of our septic lids which were replaced with unsightly risers put in our front yard. When we called to get our original lids back we were told they were gone. We have been waiting at least 2 months for them to come out and replace the risers that were put in. Each time we are given a time that they will be here, no one shows up or calls to explain why they did not show up. Each time I am guaranteed that they will be here, and I am still waiting. There is always an excuse but never any action. I am ready to file a complaint against this company. I can absolutely NOT recommend this company for any future jobs. Aside from the poor service I believe we were gouged on the price of this work. I have since had other companies come out and the price they give for the same job is about half of what we paid to GM. I see that some people have given them good ratings which shocks me because we have had nothing but problems with them since the first day they showed up at our home.
We had Morris back out today for a back up that we thought was due to the previous issues with our septic. I have to say that he was very helpful and professional. Although there were things we were not happy with on our initial complaint, I feel it is important to revise my previous rating. As it turns out, the current issue was NOT related to the previous work that was done. Morris was very thorough in making sure that the problem was resolved and was kind enough to fix a leak under the sink at no extra charge, as well as leaving his cell number to reach him directly if there were any further issues. I appreciate him getting back up here on such short notice and taking care of the problem. I guess time will tell if the original problem is completely resolved, but in the meantime, I feel it necessary to give credit when credit is due.

This update should've been posted sooner .
Morris came back a week later with the parts I needed and finished the job!
He is a true professional!
GM is an honest company with fair rates and pricing.
They are on my permanent list. I am one happy customer!
Thanks Morris!

they are very unprofessional. came to my house, collected a copay and told me that they will be back the same day to fix my pipe. did not hear back from them for 3 days. I had to call my insurance company to get status. they lied and told my insurance company that they did not have access to do the repair, but they told me that they would have to cut the ceiling to get access. my insurance company sent another plumbing company and they fixed the problem on the spot. would NEVER work with this company in the future. there are plently of other plumbing companies out there that would be greatful for your business- especially in this economy.
