Sewer Repair
Cracked clay and cast iron sewer lines, roots and repeat backups under century-old homes.
A kitchen sink that won't drain, a clawfoot tub that drains in slow motion or a basement floor drain that fills on laundry day. We clear it, explain why and price it before any work. Our office is on Ravenswood Avenue. Open 24/7.


Call when plunging hasn't worked, the same drain clogs again soon or you smell sewage. Then check who else is affected. If only your sink or tub is slow, the clog is in your branch line. If the upstairs unit's drains are slow too, or the basement floor drain is filling, the shared main line is blocked and needs sewer rodding.
Hair and soap in bathrooms, grease in kitchens and lint from laundry cause most clogs. We clear them with a cable sized for the pipe and show you what came out.
Many Ravenswood homes still have original galvanized and cast iron drains. They narrow with age, so clogs come back faster. A camera look tells us whether a stubborn drain needs hydro jetting or a section of pipe replaced.
Grease is behind most kitchen clogs. It coats the pipe and traps food and soap.
In a two-flat or condo, stacked kitchens often share a drain. If your sink backs up when your neighbor's dishwasher runs, the clog is in the shared line. If the disposal is involved, see garbage disposal repair.
Century-old pipe and shared lines make clogs a regular call here.
Rough insides catch debris.
Several units share one vertical drain.
When every unit is slow, it's the main. See sewer drain clearing.
When the basement floor drain backs up or every unit's drains slow down, the main sewer drain is blocked. It takes a machine that can reach from the cleanout to the city sewer.
We clear it and scope it so you see the cause, usually roots in old clay or grease from several kitchens. If it keeps happening, we'll go over rodding, jetting or a repair.

"I had a camera inspection as well as a Hydrojet cleaning, rod, and flush of my 70' main 6" sewer line... The camera inspection was done by George and Raul. They were prompt, professional, and detailed with the description of the process... we were able to see together where the problems were in the main and at what specific distances. I was given several options for resolution on the spot with price quotes up front."
