Pulled my dead fridge from it's cubby and found water leaking. Drywall had disintegrated. Poseidon was available right away! He was clean and knowledgeable and he's an experienced tradesman. Very professional. He got my new valve installed quickly and neatly. He double checked his work before he left. I couldn't be more pleased! Their price was reasonable as well. I'm a contractor and I've seen the good ones and the bad ones. Poseidon is one of the exceptional ones!
