I had a wicked combo of 50 yr old bathtub faucets ( the hot water completely frozen in the “on” position) and a 13 year old hot water heater …. Yep, on Saturday … 2 Sons sent Carey out on Sunday and he advised me to wait until Monday when he could really solve my problem with high quality hardware and a new hot water heater! Carey came out Monday with Micah , beautiful copper pipes, a new hot water heater and a modern bathtub faucet. In 5 hours I had a new bathtub faucet and a new hot water heater. On top of really good craftsmanship , they respected and protected my existing tub/ toilet / sink. Thanks for a job well done!! M & M Watts

Have used 2 Sons multiple times to help with the plumbing in our house and every time has always been great. This time was no exception. Dave was amazing - very knowledgeable and reasonable in his suggestions and treatment of our plumbing issues. He was also very kind and was respectful of our house and space. Would definitely hire him again.

2 Sons Plumbing did a fantastic job! I had a difficult water line replacement job, and they were friendly, quick and professional. The work turned out great. I had Dave as the project manager and he was honest and great to work with.

Would use them again for sure.

The 2 Sons company was prompt, thorough, clean, and performed precise, high-quality work. The office staff and plumbing technician showed professionalism and a focus on details. The finished repair exceeded our expectations, the price was very reasonable (high value for the quoted price), and the technician left the Job site spotless. See attached photo, they used the Big Bertha Motorized Snake to clear a clogged drain, the obstruction was 25 feet away!!

Great service over a holiday weekend. Total failure of our sewer line was fixed with a ten year warranty. Clean, great communication, full fix. It cost a lot -- I mean, it was a major repair in a hundred year old house-- but was reasonable for what we received, and the pricing was very transparent. Seth, Jorge, Shane, Dan, and others were all perfectionists and appreciated.

2 Sons Plumbing is a top notch company. Recently I had a water line hooked up for a new refrigerator and Justin and Bryce were my technicians. They were so competent, careful, and efficient and I really appreciated their professionalism. Justin even showed me how to use the displays on the new fridge. They made sure every thing was clean, the lines flushed and working before they left the house. Their pricing is extremely reasonable also, I got two quotes for installing the waterline and 2 Sons was the most reasonable. Last year I had a clogged kitchen drain during the Christmas holiday's and 2 Sons Plumbing was the only company that would come out right away and not charge a high holiday rate. I highly recommend 2 Sons Plumbing for any plumbing needs.

This is the second time I used 2 Sons Plumbing. This project was to install a toilet. Like the first time, the toilet installation went flawlessly. The support from Autumn and the other folks in the front office made scheduling easy and they were able to reschedule it to meet some changing circumstances on my end. I requested Brandon to do the work as he performed my previous job. He also recommended a high quality toilet that worked in my situation. I was called and texted to let me know he was coming. He was fantastic and explained how he was going to do the work and showed me the conditions of my existing connections. He got it done very quickly and efficiently and did not leave any mess. I’m super impressed with how this company operates.

Thank you, Bob, for your professional, courteous, and kind service! My downstairs tub was running with high pressure due to some worn out stems. Bob was thorough—but unfortunately our fixtures are quite old, and he didn’t have appropriate replacements available the first day. However, they were able to find the appropriate stems for our tub and fixed the leak right away day 2. I cannot speak highly enough about how grateful I am for the way 2 Sons accommodated my schedule when they needed to return with the appropriate fixtures. The technician was a genuine joy to work with—and I appreciate the quick follow up and turn around. I also appreciate the way Bob walked me through the process and double checked for leaks.

We had a great experience. Brandon and Chris were very polite and professional. We had a massive leak under a toilet and they came and fixed it on a Saturday. They were very timely and hardworking. Ethan was another who was also very polite and professional. Pricing was also very manageable for the extent of the problem we had. I would highly recommend.

He also gave me a helpful heads-up about our heater and offered great advice. I really appreciate the professionalism and will definitely use them again!
