Roots, a bellied section, scale, a crack and a plug of grease all look identical from the top of the pipe. A camera is the only thing that tells them apart.
A cleared drain tells you the line is open today. It tells you nothing about why it closed, and therefore nothing about whether it will close again.
A camera answers that. Roots need a different response from a bellied section; a hard grease layer needs jetting rather than cabling; a cracked or offset joint is a different conversation entirely. Each of those produces exactly the same symptom at the sink.
We locate defects from the surface as well, so if a line does need excavating, the digging happens in the right place.
Blocked drains rarely travel alone. Here is what else we handle.
See what is actually in there, and keep the footage.
