Ranches and Brick of the 1950s
Dunning filled in largely after the Second World War with brick ranches, Georgians and bungalow variants. Laterals from that period are typically clay, and they are now old enough to have settled joints and root intrusion.
Seventy-year-old clay is the most common thing we camera in this neighborhood - generally intact, frequently with one or two joints worth watching.
Newer Homes on Redeveloped Land
Sections of Dunning were redeveloped more recently on former institutional property, producing pockets of newer housing with PVC service lines among the postwar blocks.
Newer pipe removes the root problem but not the possibility of a bad install. New-construction clogs almost always trace to grade, debris or a tie-in rather than to pipe age.
Two Different Conversations on One Street
Because eras sit side by side here, the right advice varies sharply between neighbors. An owner of a 1955 house should think about root intervals and eventual lining; an owner of a 2005 house should think about what changed recently.
In both cases, recurring clog diagnosis starts from the same place: what the line looks like inside.

From Poor Farm to Quiet Residential Neighborhood
Dunning takes its name from Andrew Dunning, who owned land on the far Northwest Side in the 1800s, but it became widely known for the Cook County Poor Farm and insane asylum built there in the 1850s and 1860s. The institution, later the Chicago State Hospital, grew into a large complex, and thousands of patients and poor residents were buried in cemeteries on the grounds, some of which were rediscovered during construction in the 1980s and 1990s. Much of the former hospital land is now occupied by Wright College's northwest campus, the Chicago-Read Mental Health Center, housing and parks.
Residential development in Dunning came relatively late. Most of the neighborhood's homes are brick bungalows, Cape Cods, Georgians and raised ranches built from the 1920s through the 1960s, giving it a more suburban character than neighborhoods closer to downtown. Streets are quiet, lots are reasonably sized and trees are mature.
Because most homes were built within a few decades of each other, their plumbing shares common features: cast iron stacks inside and clay laterals outside, now sixty to a hundred years old.
Bungalows, Cape Cods and Raised Ranches
Brick bungalows from the 1920s follow the standard Chicago design with a basement floor drain as the lowest opening and a front-wall cleanout. Cape Cods and Georgians from the 1940s and 1950s have similar basement layouts with more fixtures on upper floors. Raised ranches built in the 1950s and 1960s put family rooms, bathrooms and laundry on lower levels close to sewer elevation, and some rely on ejector pumps to lift waste from those fixtures.
When a raised ranch's lower-level drains back up while upstairs fixtures work normally, the ejector pump or its check valve may be the cause rather than the main line. A bungalow floor drain backup, on the other hand, almost always points to the main.
Telling the crew what kind of house you have and which fixtures are affected helps them diagnose the problem before they arrive.
Mature Trees on Quiet Streets
Dunning's residential streets are lined with mature parkway trees planted when the neighborhood was built. After six or more decades, those trees have extensive root systems that reach the joints of aging clay laterals. Root intrusion is the most common cause of recurring main line backups in the neighborhood.
Rodding with a root-cutting head clears the blockage, but roots typically return within a year or two. A camera inspection after rodding shows how many joints are letting roots in. If only a few joints are affected, a spot repair may solve the problem; if many are affected, lining the lateral seals it permanently without digging up the lawn or parkway.
Homeowners who prefer ongoing maintenance can schedule rodding before roots rebuild into a full blockage, often every twelve to eighteen months.
Storms and Basement Flooding
Dunning drains into Chicago's combined sewer system. During intense summer storms, the mains can fill beyond capacity and push water back up laterals into basements through floor drains and lower-level fixtures. Homes with finished basements or lower levels face the highest risk and cost.
Many owners have installed backwater valves, which close automatically when sewer water tries to flow into the house, or overhead sewer systems, which raise the home's connection to the main above the basement floor. Both are effective when properly installed and maintained.
Sump pumps handle groundwater from drain tile around the foundation. A battery backup keeps the pump running during power outages, which often accompany severe storms.
Postwar Cast Iron Inside the House
Cast iron drain lines in Dunning's postwar homes are now sixty to seventy-five years old, and many have developed internal scale that narrows the pipe. Kitchen lines are especially prone to grease buildup, and older galvanized branch lines can corrode nearly shut.
If drains stay slow even after cleaning, descaling can restore flow in cast iron that is still structurally sound. Badly corroded sections may need replacement. A camera inspection of the interior lines shows what you are dealing with.
Addressing interior pipe issues during a kitchen or bathroom renovation is much easier than after the new finishes are installed.
Wright College, Parks and Institutional Land
The former hospital grounds now host Wright College, the Chicago-Read Mental Health Center, Dunham Park and other facilities. Large institutional properties have their own drainage systems managed by facility staff, but the surrounding residential blocks rely on the same aging city infrastructure as the rest of the neighborhood.
Streets near large open spaces and parks may see different runoff patterns during storms, as water from lawns and paved areas flows toward the nearest sewer inlets. Homeowners near these areas should keep an eye on basement floor drains during heavy rain.
If several homes on your block back up at the same time during a storm, report it to 311 so the city can evaluate the local main.
A Maintenance Routine That Works
For a typical Dunning home with mature trees and an original clay lateral, a maintenance plan might include main line rodding every one to two years and a camera inspection every few years. That approach keeps roots from causing emergencies and provides early warning of structural problems.
Simple habits help too: keep grease out of the kitchen sink, avoid flushing wipes, use hair catchers in showers and keep the basement floor drain clear. Test sump pumps and ejector pumps once or twice a year by running water into the pit and watching the float trigger the motor.
Keep a record of every service visit, including what was found and how far the cable reached. That history helps future crews and is valuable if you sell.
Service in Dunning
Crews serving the Northwest Side cover Dunning along with Portage Park, Norwood Park, Montclare and Belmont Cragin. When you call, share your address, the type of home and which fixtures are affected. Mention if you have an ejector pump, sump pump, backwater valve or overhead sewer.
For main line clogs, the crew will rod from the basement cleanout toward the street. For recurring problems, a camera inspection after clearing is recommended. Pricing is confirmed on site before any work begins.
If you are buying a home in Dunning, a sewer camera inspection before closing is one of the best investments you can make. Many homes here are coming up on the age when original clay laterals start to fail, and knowing the condition of the line lets you negotiate or plan ahead.
Frequently Asked Questions
What pipe is under a 1950s Dunning house?
Most likely clay to the street. A camera inspection confirms material and condition.
My newer house clogged. Is that normal?
Not really - on PVC, early clogs usually mean construction debris, insufficient grade or a poor tie-in, all of which show on camera.
Do I need annual rodding?
Only if your line’s history calls for it. Many postwar lines here go years between problems.
Can a crew tell how bad a root intrusion is?
A camera shows how much of the pipe diameter is obstructed and at which joint, which is what determines whether rodding is enough.
Is power rodding harder on pipe than hand rodding?
With the right head and operator, no. It is the standard tool for roots and heavy blockages in a main line.
Can a crew serve the Belmont Heights and Schorsch Village areas?
Yes, the whole community area and its adjoining blocks.
Should I replace clay pipe preemptively?
Not without cause. Sound clay can last a long time; replace or line when the camera shows a reason.
How fast can someone reach Dunning?
How soon a crew can come depends on availability; call to check timing.
