Cleaning solves a blockage. It doesn't fix a cracked, collapsed, or root-invaded pipe. Knowing the difference before you call someone out saves time and money.
The same clog keeps coming back within weeks of cleaning
Sinkholes or soft spots appearing in the yard above the line
Sewage odor persisting even after a line has been cleared
Multiple fixtures backing up simultaneously
Can a camera inspection tell the difference?
Yes, it's usually the fastest way to see exactly what's happening inside the line before committing to a repair approach.
Is trenchless repair an option for most structural issues?
Often yes, depending on the extent of damage, it's worth discussing with your contractor before assuming full excavation is needed.
If cleaning hasn't permanently solved the problem, a camera inspection is the next right step, not another round of cleaning.
