Recommended Customer Reviews
Gloria V.Very professional. Good communication, friendly and try to fix the long term problem for you. John who came after hours for the work, when above and beyond to try fix my problem, thank you very much. I am highly recommend this place.
We had some issues with our plumbing and Taylor and John helped us immensely. Super pros and straightforward, quality, and really helpful with ideas and options - taught me a ton. I give my strongest recommendation.
My water heater pilot has been off/on for the last year. All I have ever done for a quick fix is light the pilot. However when the weather gets warmer, the pilot goes out more than usual. The other day, 3x's. I had to call Petersen to find a solution. He came out immediately, explained the possibilities of the problem. But because my water heater was so old and it could cost me more to fix, he suggested I replace it completely with a tankless. Something in the long haul, will save me more $, save me more water and overall more efficiency. He removed the old tank and replaced it with the tankless. I love the fact that I can have endless hot water too! Thank You again!
Absolutely fantastic experience. They turned a crappy situation (no pun intended) into a positive one. Fast, responsive, clean and professional. I scheduled them to come back out to replace the rest of my toilets and install a new water heater. I would highly recommend them.
Joshua M.Petersen Plumbing Services has done quite a few jobs in my household. Each time I have called upon their plumbing services they have excelled at every corner. They are upfront, prompt, and cordial. They run things very professionally and get the job done. I highly recommend Petersen Plumbing for their professional plumbing services. I will not go to anybody else for my plumbing household needs.
Unfortunately we had to change our review of Taylor Petersen based on our last interaction with him. Our pressure regulator valve gave out and he had to replace it and move it from a muddy hole on the curb to a more accessible location. He spent two days ( 6 hours, then 4 hours) doing this and it was a difficult dirty job. However it cost us $4200. That is a pretty spectacular hourly rate. Every plumber we spoke with said the exact job, digging mud and all, should have cost $1000 or less and in fact two of our neighbors in our condo unit had the exact same thing done for less. So when we lost our water pressure again only a few months later, we were floored and disappointed when he immediately said it must be a new problem and it would cost us another $249 for him to come check it out . He took no responsibility and gavve is a long sob story about how he has to charge that to put food on the table for his family. Well they must be eating filet mignon and caviar because we got a second opinion from a reputable plumber who said the valve was never properly set and fixed the problem for free. He also confirmed that the job should have cost more like $1000 max. Taylor was unfortunately rude and reluctant to come assess his own work which left a really sour taste in our mouths. He did some other things that were pretty slimy but will take too long to write about so I'll stop here. Very frustrating and costly to deal with.
Addendum: Mr. Peterson just informed me that he is going to come after me for $500 for writing this review.
Dany C.I spoke with Taylor regarding remodeling in my bathroom. He was very honest and to the point on what needed to be done, not price gauging me at all. He helped me create a game plan and for that I greatly appreciate his professionalism. Thank you for all you do.
Graciela V.Taylor was very punctual, efficient, & professional. He took care of our very old water heater. His fees were very reasonable. Thank you for taking care of us!
Rachel V.Punctual, reliable and responsive. These three characteristics barely cover the surface of this company. Petersen Plumbing not only fixed our sink and garbage disposal on such short notice, but they were incredibly knowledgeable and keen on educating us about preventing plumbing issues. The owner is reasonable, kind and understanding. The plumber who came to the home was incredibly friendly, professional and worked fast! Will ALWAYS recommend to anyone looking for a trustworthy and reliable plumbing company.
I found Petersen Plumbing online. I spoke to the owner and he booked an appointment with Juan for the next day. Juan was really great and so knowledgeable. He explained things to us clearly and was not only a good plumber, but personable,neat, does great work and is tidy. We were very pleased with him. We will be calling Petersen Plumbing when we need a plumber without hesitation.
