They know what there doing, but there price for the work they did was exorbitant. I'm an engineer and understand whats going on. The first staff member on the phone was a snot when I called. $570 dollars an hour for two guys, new pump, wiring, and one waste tank pumped out. Good company for emegency. My work was done during normal business hours. I'll use others next go around. Have a good day.

Olsons will do any job big or small. Dylan gave an affordable bid and was open to any questions I had. Lee and Teri in the office were responsive and gave updates as needed via calls & email. Dustin, Logan and Travis took nearby property lines into consideration when bringing in the excavator and cleaned the area up nicely. Olsons exceeded my expectations. Highly recommend. Thank you!

I'm having an electrical issue with my septic alarm. I called this company to see if they could come out and fix it. The woman who answered the phone said she'd talk to the guy that pumped my tank last year (that was the first time I had hired this co) and then she'd call me back. A WEEK later and I still hadn't heard a word from anyone. So I call them back to find out what's going on, she asks me if I know of any electricians I can hire. I tell her no, she tells me they have a few they work with and that she'll see if she can find one that can come out and take a look and she'll call me back.

I called for information on addressing a very old backed up septic system at a parent's house. They spent lots of time with me on the phone laying out several options from service to repair to replacement. It helped me make the best short term decision and know who to contact for designing a replacement system. I will definitely use them when it is time to replace the system as well.
