Most drain problems aren't visible at the surface. A gurgling toilet, standing water in a tub, or a floor drain backing up during laundry all point to something downstream, but identifying exactly what is causing it requires the right diagnostic tools.
We run a waterproof video camera down the line to see the pipe's interior in real time. The camera captures the location and nature of every problem: root intrusion, a crack at a joint, a collapsed section, grease buildup that's narrowed the pipe to a fraction of its original diameter, or an offset where one section has shifted relative to the next. We mark the precise above-ground location before any excavation or repair work starts.
From there, the right repair depends on what we find. A localized crack in an otherwise sound line can often be addressed with trenchless pipe lining, which inserts a structural resin liner through the existing pipe without digging. A section with multiple failures or heavy root infiltration usually calls for spot excavation and replacement of that segment. A drain line that has failed across several spans, which is common in clay laterals over 40 years old, is a candidate for full replacement, and trenchless sewer line repair methods let us do that with minimal disruption to your yard or landscaping.
For interior drain lines, we clear clogged drains using HydroScrub® drain jetting when buildup is the issue, or replace corroded pipe sections where the pipe wall itself has failed. Every repair at Mr. Rooter Plumbing of McHenry County is backed by the Done Right Promise®.
