First - I narrowed my selection to three highly rated drain cleaning companies including Tinker Plumbing. I called all three the night before (around 10 PM) the service date and left messages. Tinker Plumbing was the first to call me back in the morning (around 9 AM), so I scheduled with them. I asked about pricing, and was told the sewer cleaning tech would provide that when he arrived.
Ken arrived in the scheduled window. He quoted me a minimum price based on time immediately. I don't know why the person scheduling could not have done this.
It took about 10 minutes to resolve our issue. Ken then asked if I wanted to send a camera in the line to see what the possible cause was. I declined but would happily call them back if any sewer line repairs needed to be done in the future.
