Best Seasonal Maintenance in Columbus OH

We've used the Waterworks before in the past but was not satisfied with the most recent visit. We had a kitchen sink that was clogged up so their tech came by to fix it and offer an estimate of the full price. I knew up front that there would be a service fee of $60 that would roll into the full service price (BTW not all plumbers charge this) but what I didn't know was that the price to unclog the drain was $214 and it only took 20mins to do. Really?? $214 for 20mins of work and there were no parts needed?? If that's the case then their Labor rate is over $600/hour which seems a bit on the high-end. All the folks that I dealt with on the phone leading up to the appnt and the tech were very nice and professional but their pricing is not customer friendly. For 20min of work there should be some price ceiling. I filled out their post-service survey and shared my experience asking for someone to call me but no one has. Buyer-beware here.. :-( Scott
