"I had an excellent experience with Jose Plumbing Excellence Northwest. They first helped me fix a leak, and later replaced my water heater when it went out. Both times, they were able to schedule me right away, which I really appreciated. The team was professional, efficient, and made sure everything was done correctly. Their customer service was great from start to finish, and they made the whole process smooth and stress-free. I highly recommend them for any plumbing needs!"

"This was by far the absolute worst experience that I have ever had with any company. The plumber came out for a shower that was not draining. I am on septic and let them know that my septic was just pumped in July. However they wanted to check anyways. After checking under the baffle inspection, I was advised by the plumber that my septic tanks were full and needed to be pumped. I contacted a septic company they came out first thing the next morning and checked my septic tanks, they were not full and ironically enough was able to pull out a huge clog of toilet paper from the baffle. He advised this is something that the plumbers do but since we just had one out the day before and they did told us the wrong information he would happily fix the problem for us. My husband called Riley Cahill (the manger) the next day to try to talk to him about the situation and try to find out why we were charged so much since there was not an itemized receipt. Riley proceeded to get very defense and angry and HUNG UP on my husband. He then called back left a message that saying he will check with his plumbers on Monday and get back to us. Monday morning I called Riley Cahill to have a conversation of what went wrong and how we will remedy the situation. He proceeded to once again get very upset, raise his voice and was insanely disrespectful (telling me to be quiet and stop talking). Then hung up on me as well. After that he called back to tell me I was wrong, and hung up on me again. I told him during the conversation that I was going to warn anyone I could not to use this company through reviews, DO NOT USE THIS COMPANY!!!!"
