Recommended Customer Reviews

Couldn't ask for a better plumber friendly and efficient service. Would definitely recommend him to everyone that's in need of a plumber.

Let me say that I've lived in my home for two years and many others before it and always and couldn't stand some of the maintenance people that came to fix things UNTIL ''Philip Graham'' from Graham ~Maintenance Plumbing Corporation~ I had a plumbing emergency after hours called my management office as they were closed but left a emergency plumber's number which I called and Philip answered the phone right away and was very polite and told me when he would be here and by god he was on time handled my problem immediately,efficiently and correctly and as he was very busy doing his job I brought to his attention that my water heater was leaking he took a few pictures talked to my management company and negotiated with the owner on my property and was back in my home installing a better brand new water heater within a few days from the last time he was here so for Philip and his company I will always use them and request him from any management company I ever deal with *FIVE*VERY*WORTHY*STARS* FROM THIS guy thank you for your fantastic services

I've had three jobs performed by Graham plumbing. They have been on time, friendly and very reasonably priced. I would recommend this company to anyone.

These guys came out twice.
On first visit, my water heater's pilot wouldn't light and I didn't get a chance to call until late at night. 24 hour plumbing services are hard to come by as I have learned, but Graham maintenance came and fixed the problem with professionalism and without price gouging. I believe the tech was the owner and his name is phil?
Second visit, they changed some pipes out that I didn't notice were leaking/damaged until pointed out on the first visit. They were professional, efficient, and arrived actually early.

I was referred to GM plumbing from my current management company who has been in business for 30 years. I own several buildings and GM Plumbing has done an outstanding job! They are Professional, Honest and Reliable.
GM Plumbing has replaced water heaters in three of my buildings, replaced toilets, unclogged sinks, water valves etc.
Most recently Philip Graham (the owner) did a re-pipe and unclogged the main sewer line at one of my properties and is currently working on adding a new laundry room to one of my buildings.
I know that when I call Philip Graham its one less thing I am going to have to worry about. He gets the job done right the first time unlike other plumbers who gauge you and tell you the units need something when they really don't.
I have personally dealt with Philip Graham and he always returns my calls immediately and arrives when he says he is going to. Philip explains what needs to be done and discusses options and always follows up with an email or phone call.
I use GM Plumbing exclusively and totally recommend GM Plumbing to anyone. I have worked for many plumbers over the past 15 years and I finally made the right choice choosing Philip Graham as my plumber. ""WHEW"" Absolutely the Best!
Most importantly, GM Plumbing keeps my tenants Happy.

Excellent job, and they have been very patient with me about making my payment. Highly recommend!

My husband has been using Graham Maintenance Plumbing for many years for rental properties and now we use their service for our own home. They are extremely professional, respond quickly to requests for service, and provide quality work for a reasonable rate. All the employees have been very kind and respectful and I appreciate the fact that they do a good job cleaning up and even ask if they can help put items back under the sink. I would highly recommend Phil and his team for any plumbing job.

I supervise too many units to count and if I didn't have Phil as my ""go to"" plumber I wouldn't be able to do my job efficiently. I rely on him so much that it's put a stop to the business I used to dish out to other plumbers. Believe me it's not a knock on the other guys but Phil is fair, polite, and will be up front with you about cost before a job is done. Quality of work is superb. He treats everyone with respect (I should know, I'm much younger than him and he still calls me sir). If you don't like the guy right off the bat, there is definitely something wrong with you. All you could ask for in a multi-tool plumber. He and his brother are very organized and really are the epitome of building a business from the ground up. You are first on my list buddy.

We live in a rental house and the property management uses these guys. We've had to have them out several times for plumbing issues and they are truly the best. Very professional, very nice, quick, and have come late at night same day. Will seems extremely knowledgeable, I'm pretty sure he could do this stuff with his eyes closed. Great work, I very much recommend them.

So, I didn't want to have to write this review, because I really really wanted to like this outfit. Let me keep it as short as possible, but I fear that's not possible as I have to refute some misrepresentations and lies.
1. The initial consultation was great. GM was responsive and had well written proposals for the bathroom remodel of a tub demo and pre-fab tub/wall install. I was told they would build out the wooden carriage and ensure everything was done professionally.
2. They were patient with my indecisiveness and answered my many questions. I even considered a tile install after seeing great photos online. That's when my doubts crept in when I found out the tile person wasn't available....I'll explain why shortly. We agreed on a 2 day install upfront Monday-Tuesday.
3. Day of the install the lead contractor was late, 30 minutes, no big deal, but in hind sight, it proved very telling. The subcontractor seemed nice and went right to work. The contractor was only on site twice during the day. That's okay, I suppose, but provided he should be there at the conclusion. My doubts crept in when I asked the subcontractor if he did tile work. ""Yes, I can do tile work"". Do you do it for this firm? ""Yes"". So I wondered why he didn't have this guy do it? Sadly I found out later.
4. Day 1 of the install, the contractor tells me, I think we can finish in one day. Okay, great. Of course, who wouldn't be happy right? Later at 6:30p I overheard the contractor on the phone with the subcontractor - ""Are you still there? You've left already haven't you""? At this point the subcontractor is scrambling to finish and leave by 7pm (started just after 8am working straight through). So the 2 day job became a ""hurried"" 1 day job. I can only guess the worker could not longer be committed to 2 days. The subcontractor told me in the morning he would put up tarp so we could shower that night. Obviously, plans changed and my job got ""rushed""
5. The subcontractor left, I paid, and then we started to look more closely. There was spackle or sealant on the carpet (fine we were changing our carpet that week on Friday - not the next day). There was the same white sticky stuff on our front door, down the hall way and down each stair of our condo unit for 3 levels. Okay, not clean. Then, looking at the shower, the sealant job looked terrible. It's not something we noticed right away because it's all white on white. When I started to clean the shower I noticed it was sticky all over. The whole point of a pre-fab fiberglass shower was an easy to clean tub! It wasn't easy to clean. My wife and went into cleanup mode, with her doing the hardest work, and 3 hours later we were able to relax after 10pm. My wife was pissed.and when my wife is pissed, uh yeah, I'm not happy either.
6. They also replaced the toilet flush with a new kit. The second day it wouldn't stop running water so my wife called the contractor. He said he could come out, but never said ""I""m sorry"". When I talked to the other contractor partner, he did apologize to his credit. I told him I had fixed it so there was no need to come out. I informed him, and later by voicemail informed the lead contractor ""my wife was pissed off at the sloppy job. and the toilet was the final straw"".
7. My wife gives her review with a 1 star. The contractor texts me after 10pm on a Friday night complaining about the review. I had no idea as my wife wrote it. Of course I support my wife and I told the contractor I was okay with the initial job, etc, but the sloppy finish left us with a bad impression. Lasting impressions matter.
8. Now the Contractor responds to my wife's review and says I was happy with the job. Now, tell me, who does this? Who in their right mind tries to pit a husband and wife against each other? That makes for terrible customer service, fortunately for us, we are a united front. Oh, and now he invents an excuse that I was having carpet installed the next day. That's 100% B.S. I said I was having it on Friday, not Tuesday which I had already blocked out on my calendar (and by invite).
The toilet started flushing twice tonight. I'll call my usual plumber (see my review). It's too bad that instead of lying, there wasn't an offer to clean up the mess. I broke my cardinal rule on this gig. When someone tells me ""I'm honest"" I'm usually suspicious and don't trust them. Don't tell me, prove it to me. Never again, I'll steer clear of anyone who has to tell me they are honest instead of proving it to me.
I wish them no ill will, but this is my opinion based on the facts. I was going to let it go, but once you lie our put false words in my mouth, I'm going to call you on it everytime. Buyer beware.
