Sewer Repair
Cracked clay and cast iron sewer lines, roots and repeat backups under century-old homes.
A toilet that runs, leaks at the base or clogs every week. We fix it or replace it, and in older homes we check the flange under it too. Our office is on Ravenswood Avenue.

We handle:
A flapper or fill valve.
A failed seal or corroded flange.
An older toilet or a line problem.
Loose bolts or a damaged flange.
In older homes, the toilet is often newer than what's under it.
The toilet won't stay tight.
A failed seal can stain the ceiling downstairs.
Some drain to an ejector pump.
Repair or replace, explained.
Tank, bowl, seal and flange.
First.
Tight and sealed.

The flange is the ring that holds the toilet to the drain. In older Ravenswood homes, it's often cast iron or lead attached to the old pipe, and it can corrode or break. When that happens, the toilet rocks, the seal fails and water seeps into the floor, sometimes reaching the ceiling below. We repair or replace the flange before setting the toilet, so it stays tight.
Small repairs are quick. Replacing a corroded flange takes longer. Carrying a new toilet up narrow stairs adds a little time. We check and quote a flat price.
