Sewer Repair
Cracked clay and cast iron sewer lines, roots and repeat backups under century-old homes.
Low pressure from century-old pipe, a stain spreading on the ceiling or a neighbor reporting water. We find leaks, repair the pipe and tell you honestly when it's time to replace old galvanized lines. Our office is on Ravenswood Avenue.

Watch for:
Old galvanized pipe closing up.
Corrosion inside the pipe.
Under a bath or kitchen.
Common in shared buildings.
We work on:
Galvanized, copper and PEX.
Cast iron and galvanized.
Old galvanized lines replaced with new pipe.
With nearly half the homes built before 1940, original pipe is common.
It rusts inside, cuts pressure and leaks at threaded joints.
In a two-flat, water shows up far from its source.
One leak can be repaired. A failing system is better replaced. If a pipe has burst, see burst pipe repair.
Find it first.
Listening tools and pressure tests.
Repair or replacement, explained.
No guessing.

Replacing galvanized supply pipe in an older Ravenswood home doesn't always mean opening every wall. We trace the existing lines, then plan new routes through the basement, closets and plumbing chases. In a two-flat, we can repipe one unit at a time. You'll get a clear plan, a flat price and an idea of which walls, if any, need patching afterward.
Finding a leak between floors takes testing. Reaching it may mean opening plaster. Repairing one section is quicker than replacing a run of galvanized pipe. We find it and quote a flat price.

"Andrew was very professional but also personable, explaining the issue and how they were going to fix it and gave me some tips to help avoid having a recurrence. They were able to get my kitchen sink up and running again right before the holidays which was a life saver."
