Warning Signs
When to Call
Not every slow drain needs a camera, but if the problem keeps coming back or you're dealing with something the snake can't fix, an inspection tells you why. These are the most common reasons homeowners call us for a camera job.
Drains keep backing up after clearing
Wet spots in the yard near sewer or leach field lines
Previous repairs didn't fix the problem
Sewage smell inside or outside the house
Buying or selling a home with older plumbing
You want to know the condition before committing to a repair
