Hear What Our Customers Say

  • Our pipes froze and burst in our garage. Cocos Plumbing sent someone over right away. I was relieved to have them fixed before any water damage occurred. Thank you for the prompt, courteous service!

  • Opening up a new restaurant is stressful enough without worrying about the quality of your plumbing contractor. I am extremely pleased with the work Cocos did at Epic Pizza.

  • We had a full kitchen remodel that we needed some expert help and advice on. I can’t think of what the guys at Cocos could have done better. They helped us pick out the exact faucet and sink to compliment the room perfectly, and installed a new garbage disposal that should give us many years of hassle free service. Can’t say enough good about them! 5- stars.
