A drain problem comes with a fair question. What exactly is about to be put down my line? The answer matters. Drain equipment ranges from a hand snake that fits in a trunk to professional machines and cameras that handle the whole run and see everything in it. In an older line that's narrowed over the years, the hand snake isn't going to reach the problem.
Here, the call sorts things out before anyone arrives. You'll be asked what's draining slow, whether that's a shower or tub, a sink, a toilet, the laundry line, a floor drain or a cleanout out in the yard, how long it's been going on, what's been tried, and what kind of home it is. The equipment that shows up matches the actual problem, and if the line's behavior suggests something worth seeing, the camera goes down and takes the guesswork out.
When the findings are bigger than a clog, you'll get them explained clearly and completely, and then you get to weigh them without anyone standing over you. The choice is yours.
