Recently my back flow device failed and Darrin went out of his way to fix it for a very reasonable price.

I had Ross come out to inspect standing water and a sewage odor in our front yard. Without doing…read moremuch in the way of investigatory work, he concluded that repairs would cost between $15,000-$20,000. When I asked how he arrived at that estimate, the response was simply, "I've been doing this for eighteen years." He stated that our sewer line could not be scoped and that the entire system would need to be overhauled, including excavating the front yard. That recommendation felt extreme given the lack of diagnostic evaluation. I'm very glad I sought a second opinion. The actual issue turned out to be a faulty switch on a grinder pump, and the repair was under $1,000. Additionally, contrary to what was stated, our sewer line had already been scoped when we purchased the home. This experience raised serious concerns for me regarding the accuracy of the assessment and overall integrity of the recommendation. I strongly encourage others to seek additional opinions before committing to major repairs.

Buyer Beware. This company is a rip off. I asked for a quote for three running toilets and a hot…read morewater cleaning. I got a quote for $1900.00. I did give them my card and it was ran through right away. When my daughter got home she said I do not think so. Call them a cancel the service. Was given a call today stating to refund me my money will cost me $115.00. I will be disputing all this with my bank. But please do not use unless you get a couple of quotes. I think these people looked at my home and that I was an elderly lady and thought it was okay to overcharge and apply fees.

Christensen provided me a fast and accurate quote to add a safe natural gas stub out. I sent them…read morea clear photo and they didn't give me the runaround like 2 other places did. Luke and Colby came out next morning and got it done fast. Very impressed how punctual, professional and nice they were. Before I got in touch with Christensen, one other guy (GWTFP who surprisingly had high ratings was 3X higher on his quote!) probably because he didn't want this "little job" (also known as cherry picking). Another large chain wanted $99 just to show up for "diagnosis"... LOL but nothing is broke. It was a simple 40 min job to add pipe in an easy outside spot. So I didn't fall for the other's scams. I'll call Christensen next time. Highly recommend them.

I cannot possibly convey how awesome Christensen Plumbing is all around. When I texted them for a…read moreservice request, they replied to the text within minutes. We scheduled an appointment for the next day and immediately started receiving notifications from their computer system. Two of their staff showed up as scheduled and were able to provide an immediate estimate, and then were able to start work right away. They fixed two major issues - an outdoor leaking faucet (in winter when it was cold), and an indoor shutoff valve. Their team replaced our 30 year old hand-crank shutoff valve with an amazing, easy-to-use modern system (see photo attached to this review). What is hard to convey is their level of professionalism. The entire Christensen Plumbing team is on top of their game. From start to finish, they were amazing.
