Sweetwater is an honest and excellent worker. Had a leak in my bathroom from the tub spout. He told me exactly what had to be done before The leak could be fixed. I took care of that and within 2 days he came back out and finished the job. Price was fair and he is very reliable.

Had an issue where our kitchen sink was getting no cold water. Dakota came out quickly after our call and fixed our problem so fast! He found a screw in the shut off valve that had probably fallen in there during our remodel done 2 years ago. I was so happy Dakota solved our problem! He was great! Highly recommend.

This was the third time we've used them. And it was as good as the first time.

I had a problem with the sink water building up and not draining. After trying to unclog it I called Sweetwater Plumbing and they sent technician Victor out to assess the issue. I explained to Victor the issue and he knew what to do right away. After running the snake he cleared the stoppage and it drains just fine now.
