The Experts at Leak Detection

Leak detection is our specialty. Leaks can be very difficult to find, as most of your plumbing is hidden behind walls or beneath floors. Our expertly trained and certified technicians are equipped with electronic leak detection equipment to locate and repair the leak.

If the leak has progressed into major water damage—which often happens—we’ll work directly with your insurance company to save you the burden of tireless paperwork. We take care of the hard part and bill your insurance company as a courtesy to you.

Leak detection may be our specialty; however, it’s certainly not the only service that we can provide. You can call on our team for any number of plumbing services, including but not limited to:

  • Drain and Sewer Cleaning and Repair
  • Water Heater Installation and Services
  • Bathroom and Kitchen Plumbing and Remodeling
  • Emergency Plumbing Services
  • Shut–Off Valve and Backflow Prevention Installation and Services
  • Commercial Plumbing Services

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.
Angel Corrales
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.
