Burst and Frozen Pipe Repair in Chicago, IL
In a Chicago cold snap, the pipes that freeze first are in exterior walls, enclosed back porches, garden units and unheated basements. If a pipe has burst, shut off the main water valve, usually near the meter at the front of the basement, and call for help. A frozen pipe that has not split yet can still burst as it thaws.

What is different about burst and frozen pipe repair in Chicago?
The building types here create predictable weak points. Enclosed rear porches on two-flats and three-flats often have a kitchen sink or laundry line on a wall that was never meant to be heated. Garden apartments have pipes close to grade along outside walls. Bungalows have supply lines running through uninsulated knee walls to an attic bathroom.
After the repair, the lasting fix is to move or protect the pipe: rerouting a line off the outside wall, insulating and air-sealing the cavity, or adding heat to a porch that holds plumbing. In a multi-unit building a burst on an upper floor damages every unit below, so owners should make sure tenants know where the unit and building shutoffs are.

Frozen and burst pipes
Pipes in exterior walls, enclosed back porches, garden units and unheated basements are the first to freeze in a January cold snap.
What to check and ask before work starts in Chicago
- Ask where the pipe froze and what would stop it happening again
- Ask whether nearby pipe was stressed and should be replaced at the same time
- In a multi-unit building, confirm who can reach the building shutoff after hours
- Ask whether the repair material is approved under the Chicago plumbing code
Licensing and permits for burst and frozen pipe repair in Chicago
Chicago adopts and enforces its own plumbing code, which has historically been stricter about pipe materials than the codes used in most suburbs, and plumbers working in the city must hold a City of Chicago plumbing license. Permits come from the Department of Buildings. Ask for the license number, and ask whether the materials quoted are approved for use in the city.
Keystream Plumbing is a referral service. We do not perform plumbing work or hold a contractor license. The independent plumber you are connected with is responsible for licensing, permits and the work itself.
What the job usually involves

Burst and Frozen Pipe Repair questions from Chicago
Where is the main water shutoff in a Chicago bungalow or two-flat?
Usually in the basement at the front of the building, where the service line comes through the wall or floor near the water meter. In a multi-unit building there may also be a shutoff for each unit. Find and test it before winter.
A pipe on my back porch froze. Should I thaw it myself?
If the pipe is intact, open the faucet and warm the pipe gently with a hair dryer or heating pad, starting near the faucet. Never use a torch. If you see a split or bulge, shut off the water first; it will leak as soon as it thaws.
