    I DO NOT RECOMMEND this business at all - just had a terrible experience!…read more Just wow, never have I ever - worker "John" comes to install a new bottom heating element in my brand new Rheem water heater, doesn't test it or bring his machine and tells me I will have hot water back in about an hour. He leaves. 2.5 hours goes by, ample time passed and I try and take a shower - within 90 secs the water turns lukewarm, another 30 secs the water is cold when the knob is on full hot. I call him up and tell him, he tells me that is odd/not right so he come back 15 mins later and tests my sink for 60 secs and is like 'its boiling' and I say let the shower water run for a few minutes and tell me that - the water is literally turning cold in our hands and I tell him something is not right, go get your tester and he says he will. So I start to draw a bath, he comes back 2 mins later from his van and tells me that all my hot water is gone because it was 'emptied out'. Straight gaslighting me. I ask him ' come feel this bathwater, it's cold' - he refused to and tells me 'it is working how it is suppose to.' I tell him if that was the case I would have hot water 3 hours after you installed the parts and you would not have said it was odd and come over here! He would not test it the water heater or heating element he installed, tells me 'I have another emergency call to go to' mid dialogue, more gaslighting and takes off. I call the dispatch twice and my calls go unanswered, so I use my business land line and she instantly picks up - like wow - I identify myself, the lady working the phone gets instantly snappy with me and tells me 'the owner will call me tomorrow'. I am like 'why can't you talk to me' she responds telling me I was "rude to her worker!" As if , I gave him freshly baked cookies first thing when he came into my home! Ya, how rude of me - what a joke. I simply called him out for not doing his job, told him basically to do his due diligence, he refused to and some how I am fault!? You know what rude is - when you employ someone who is dismissive, invalidates you, and then takes off without the job being done correctly. She goes on to tell me that it is my fault because I showered to quickly and should have waited 3 hours! Very contrasting story to what the installer John told me and conflicting information. She then hangs up on me. No way be treated. UPDATE : 24 hours later I try and take a shower , hot water does not last past 12 minute mark. When in reality should have over 40+ minutes of hot water with a 50 gallon unit. I called 'Pipe Masters' back and then screened my call. More like 'Pipe Gas-lighters'. Cant even stand by there work nor did I hear from any ownership - garbage business in my opinion.

    Sometimes recommending a company when they don't work on your house, can be more important when…read morethey do. Let me explain. A few years ago Jason at Extreme helped us out with a large job at our house. He was fixing a problem we had with other work that was done. His work was quick, perfectly done and reasonably priced. Fast forward to this past Friday. We lost power on this and our hot water didn't work when the power came back. The cold water ran fine, but no hot water although the water heater was working. I called Jason and he told me it sounded like it could be a frozen pipe. He asked me if I saw a leak and I told him I didn't. He then told me, if I wanted, to ride it out because the temperature was rising and by the morning the pipes should unfreeze on their own. The next morning, the hot water came back fine, just as he said. He could have taken the service call and charged whatever he wanted, and we would have paid to get back hot water. He was honest and once again he proved that Extreme Plumbing can be trusted. That's more important to me thank any other trait. Thank you Jason!

    This review is in addition to a review I wrote about a different job Platinum Plumbing did for me…read more After 7 years or so I once again called on Platinum Plumbing for a project. Replace the first floor baseboard with high output baseboard. Peter measured the job up and returned with Christian another day to complete the work. I admit I was impressed with the concern that was paid to how each peice was installed. A level and tape measure was used on each peice of baseboard to insure that when completed the entire run was the same height and on the same plain. Each cover was trimmed if needed so it fit together properly. When they were done they cleaned up after themselves and even helped me put my things back, which they didn't have to do. I could say I'm happy with the work they did and leave it there. The truth is I'm really impressed with the work did, it came out more beautiful than I hoped. They showed more attention to detail than they had to, and the price was very competitive. Its been 7 years and Pete is still doing really prideful work. I highly recommend you give this company a chance to work at your home or business. Im certain you're going to be impressed with the end result. Henry.
