From the initial phone call, to the technician leaving. The entire process went smoothly and all involved did an outstanding job. I was well informed and excellent repairs competed in a timely manner. Thanks to all!
Karlsen Plumbing never disappoints. Chad Held came out this morning and replaced our water softener and set up our outside sump pump hose. Did a great job fast and professionally. Chad explained how to operate and answered a few questions not related to the work done today. A great experience!

I had Tyler and Ryan come to my house to fix a solid amount of plumbing work. They are completely professional and educate clients on different matters. Karlsen Plumbing is definitely a trustworthy place to have your plumbing needs solved. Please consider using them.

Thanks and we are so glad we have earned your trust! Look forward to to working with you again!
I needed work done on my kitchen sink drain pipes. The Karlsen Plumbing employee assigned to the task was punctual, polite and professional. He did an excellent job with the repairs. I would highly recommend Karlsen Plumbing to all.
They replaced a spigot on my patio. Took 30 to 45 minutes, I wasn't timing them. I think $453.34 was excessive!
Price assessment: Overpriced
Price: $400–600

We appreciate your feedback. Unfortunately, as with everything else these days prices are continue to rise for us as well. Whether it is gas, parts/materials, labor, etc... We did double check our service software and the plumber had travel to the job and was onsite for just over an hour. With that being said, everything lines up with the labor costs, parts/material, trip charge etc... If you have any further questions please feel free to call our office and talk with either David our Service Manager or Joe the President of Karlsen Plumbing, Inc.
The Karlsen Plumbing service arrived on time (instead of my having to wait, wait, wait, ...), worked quickly and efficiently, explained the problem, fixed the problem, and told me how to deal with it should it happen again. Then, they cleaned up everything so there was no mess for me to deal with!
