I have a sink that drains very slowly and a toilet that keeps backing up, so I am trying to figure out how people usually pick a drain service around Sacramento. What would you check first before agreeing to any work? Is it worth asking whether they use augers or rooter tools, or does that only matter for bigger blockages?

My kitchen sink drains slowly and the toilet backs up every few days, so I started looking into drain unblocking options around Sacramento. What do most of you check first, the license, the response time or the way the work itself is described? I came across a page where sinks, toilets, main lines and outdoor root blockages are listed separately, you can view it here, and that level of detail made me wonder how much a company should explain before the first visit. I am also unsure how to tell if a quote for a main line clog is reasonable or already inflated. For now I am simply comparing a few local options and reading the terms carefully before I commit to anything.
