Sewer Repair
Cracked clay and cast iron sewer lines, roots and repeat backups under century-old homes.
Water in the basement or garden unit after a storm, from a backed-up floor drain or a failed pump. We find the source, fix it and help keep it from happening again. Our office is on Ravenswood Avenue. Open 24/7.

Usually one of these:
Combined sewers push water back.
Through century-old foundations.
Sump or ejector.
Plumbing water.
In July 2011, record rainfall flooded basements across Ravenswood.
Living space below grade is the most exposed.
Different problems, different fixes.
We figure out which you have.
Some water is a plumbing problem and some is the foundation. We handle the plumbing side: backflow valves, standpipes, overhead sewer systems, sump pumps and battery backups.
If water is coming through cracks in old foundation walls, a waterproofing contractor is the right call, and we'll tell you so.
Stop it, find it, protect it.
Line or pump first.
Sewer, groundwater or plumbing.
Flat rate.

Start outside: keep the gangway drain and window wells clear and send downspouts away from the walls. Then check the plumbing. A clear lateral drains better in a storm. A sump pump with a battery backup handles groundwater. If sewer water has come up the floor drain before, a backflow valve or overhead sewer is the protection that actually keeps it out. In a building with a garden unit, that last step matters most.

"Fantastic service! J. Blanton Plumbing provided same day service when our bathroom was flooding due to a faulty pipe. Anthony went above and beyond, and did not leave our home until the issue was resolved. He was professional, pleasant and communicative throughout the process and provided the best experience we have had in a long time. It's safe to say that we will continue to use the services of J.
