"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"I found RT Olsen Plumbing on Angie's List. Bob has a team of plumbers working for him, and to his credit, he picked up my call from the beach while he was on a short get away with his family. This may be more info than you need, but it illustrates his commitment and reliability. After checking with one of his guys to see if he could fit in a next day appointment (my day off), he confirmed back to me that they could get someone out. Daniel arrived slightly ahead of the promised time, which is never an issue. He had never done a reverse osmosis system install before, and he gave me a price for the work in advance after he had looked at all the pieces. I didn't bother to negotiate, as I needed to get the job done and it felt like a fair price, and it was the price I paid without any further increases. The price might have been higher than I anticipated to spend, given that I provided both the disposal and RO system units, but the job was done very well, and my wife and I are happy. I appreciated Daniel's knowledge and proficiency, and the peace of mind I had that the job was done right – the first time. Daniel noticed some other issues that needed repair while he was under the sink. Being the homeowner of a home where the previous flipper (I will not call THAT guy the "owner") had cut many corners and left us with many problems, I was not at all surprised. He identified why our garbage disposal always backs us up on the other side of the sink - totally incorrect plumbing. We already plan to hire RT Olsen again and will have Daniel come back. I'm confident he will get the job done. If you happen upon another plumber that I've reviewed on Angie's list, he’s been my go-to guy for a long time, but he also happens to be so many other people's go to guy now (GREAT problem for him to have). It was inevitable that I needed to have an alternative at the ready. Found it."

"This young man is living proof that you should not judge a book by itâ s cover . When he first arrived to my site I assumed he would be inexperienced because of how young he looks , but man was i wrong . . Heâ s one talented guy. Great work ethicâ s and knows just how to get the job done right . I had him dig all my trenches for my plumbing lines and he did a nice job grading everything. I litterally just had to come in and shade the trench with some sand . He also knows a lot about plumbing . I had some plumbers out on my job and it turns out the guy i hired to grade my trenches was a better plumber then the plumbers i hired to plumb!! 5 stars . Will definitely be calling him back out on the next one ."

"Guardian Plumbers came out the same day to unclog my kitchen sink through the cleanout. They had a special for $33. The camera guy came out also free of charge to make sure the ere weren’t any tree roots or more clogged debri. They were both very courteous and polite. Thank you again."

"The experience was great from the time the woman at the desk responded to my call. She was friendly, patient and courteous. The plumber arrived on time. He was clean and respectful. The price was affordable. He schooled me about leaks and toilet backups. In addition, he was patient with me answering all of my questions friendly and knowledgeable. Iâ m glad I chose them out of the three pros offered. I hope Iâ ll never need a plumber in my home again; but if I do, Iâ ll hire them and will tell others also."
