Clean And Line The Pipe
If the cast iron holds its shape after cleaning, a liner can renew it from the inside.
PIPE LINING / CAST IRON
OLD CAST IRON? CHECK IT BEFORE YOU DIG.
Older cast iron drain and sewer pipe can crack, scale inside, or leak at joints. Lining may renew it from the inside if the pipe still holds its shape. We clean and inspect it first and explain what we find.
PIPE LINING / SPECIALTY SERVICE

UNDERSTAND THE ISSUE
Cast iron pipe can build up scale and corrosion inside, which narrows the passage and catches debris. Before lining, that buildup has to be removed so the camera can see the pipe wall and the liner can sit against it. Cleaning also shows how much sound pipe remains. If the pipe still holds its shape, a resin-saturated liner can be cured inside it to form a new pipe within the old one. If sections have split along their length, collapsed, or sag, lining may not be suitable.
WHAT WE'LL CHECK
We clean the line to remove scale and debris as far as conditions allow, then inspect it by camera. We look for cracks, splits, holes, joint condition, and shape. With those findings, we explain whether lining is suitable, where access would be, which branches need reopening, and whether replacing a section makes more sense.
If the cast iron holds its shape after cleaning, a liner can renew it from the inside.
If the pipe has split, collapsed, or sags, replacement of that section may be the right repair.

GOOD TO KNOW
Have a question about your plumbing? These answers cover what we’re often asked.
Often, if it still holds its shape after cleaning. Splits, collapses, or sags may rule out lining for that section.
Scale and corrosion inside the pipe block the camera view and keep the liner from sitting against the wall. Cleaning comes before inspection and lining.
Not necessarily. The inspection shows which sections are damaged. We explain lining, partial replacement, and full replacement based on the findings.
