I highly recommend Extreme Plumbing. I’ve used them multiple times for sewer backups and pipe leaks, and they’ve done an excellent job every time. They are responsive, reliable, and timely, and they do great work. It’s reassuring to have a plumbing company you trust to show up when you need them and get the job done right. I wouldn’t hesitate to recommend Extreme Plumbing to anyone looking for quality plumbing service

I had called for service at 2pm today and by 4pm they came to my rescue. In and out extremely professional explained everything they were going to do. They were quick, efficient and completely amazing. They showed me what they did and I was just so impressed by them. They are the only company I will be calling for services in the future. I highly recommend them to anyone who is in need of plumbing services.

Called them at 1130pm, had just been woken up about the problem by my boyfriend it was a cracked pipe , they picked up right away. Owner was incredibly patient with me as I was severely freaking out. His son was at our house by 10 the next morning. He apologized for being short staffed at the time but work was done in around an hour, pipe was capped and snaked! Very polite and incredibly patient!

Well, I have to say these guys did such an impressive improvement on my plumbing situation. They took care of me in a pinch. Sal and Paul know their work and have ethics. They cleaned up my mess on an emergency and recommend some updates. No pressure. Went into a detailed description of my needs that I know I will need to adress. They are highly skilled and very good on communication and helpful with making the best decisions on my home. The owner knows my husband well and little did I know i had the owners brother that saved me from a clogged Main in the basement. Will be using them soon for my updated heating system as it's years old. They helped me in a pinch. Great service, excellent customer service and they do care about their clients.

We had some water leaking from our water heater. We called this morning and Ernie and his crew came out very quickly and assessed the problem. The water heater at 11 years old needed to be replaced as well as the valve. Everything is installed and ready to go. It was very quick and easy. The guys were awesome.

So….in 2025, my neighbor was replacing his hot water heater through extreme. They noticed mine was leaking and sent a photo. The next day i had a new boiler and hot water heater!! So when my shower was leaking into my basement, i called him again. I had had a health event and owed a lot of money for it and was not sure how I'd afford it. He came and gave the reasonable estimate to replace the rusted out pipes, shower/tub, and sink vanity. I went through home equity, which i was approved for, but took forever! The guys came they were awesome. Very professional. Felt safe leaving them in my home alone. They were careful keeping the cats in. They cleaned up when done and helped me take down light fixtures i was never able to do on my own. They had to level the floor and jerryrig certain things because my house is soooo old and unplumb!! I let Ernest pick the shower/ tub and vanity. It's beautiful! Thank you for the wonderful work. (My home is so old, the guys found old toys and 2 right shoes in the wall)

The best plumber I have worked with! They were very quick to answer and come and see the issue and correct the situation. They replaced my broken water heater and very old forced hot water boiler with one new efficient device for both hot water and heat. A great team of hard working guys showed up and removed the old and put in the new. They were nice, efficient and clean! The price was less than expected, I will definitely call them next time I need plumbing.
