Total rip off. Prices are absolutely outrageous!

JC from Streamwood, IL

In all the years that we've had our sewer rodded, I have NEVER been charged such an outrageous price. I realize the added cost because it was emergency service and late on a Saturday night, but to charge $450 to rod and then another $350 to take a toilet off that took less than five minutes...RIP OFF! Then not to point out after spending $850 that there is no warranty because he couldn't rod far enough out to the main sewer and then say yeah I can tell you where the clean out station is after I rod, and then say oh no I can't because my camera is too "flexible" and won't bend...REALLY?! TOTAL RIP OFF! Don't waste your money on this company. They take advantage of people's vulnerability in a time of their desperation. Now we know how they're paying for all those radios ads...it's at our expense! RUN AS FAST AS YOU CAN!

Quick diagnosis and repair, personable repairman
