About This Service
Parapet Wall Repair in Chicagoland
A parapet is the section of wall that extends above the roofline. Because it's exposed to weather on both faces and the top, it sees more water, more freeze-thaw, and more movement than any other masonry on the building — so it's almost always the first to deteriorate. On Chicago two-flats, commercial buildings, and greystones, failing parapets are one of the most common and most urgent masonry problems we see.
We repair and rebuild parapet walls from tuckpointing and coping repair through full rebuilds of the section above the roof. Because a deteriorated parapet can shed brick onto the sidewalk below, it's both a building-envelope problem and a safety problem — and it should never be left through another winter once it's moving.

Warning Signs
Signs You Need Parapet Wall Repair
Leaning or Bowing Parapet
A parapet that's tilting or bowing has lost structural integrity and can fall. This is a safety issue that needs prompt attention, usually a rebuild.
Cracked or Open Coping Joints
The coping caps the parapet and sheds water. Open or cracked coping joints let water pour into the wall from the top, accelerating failure.
Crumbling Mortar Above the Roofline
Mortar fails first where weather is worst. Receding, crumbling joints on the parapet are an early sign the most exposed wall needs work.
Displaced or Loose Brick
Shifted or loose brick on a parapet is both a water path and a falling hazard over walkways and entrances below.
FAQ
Common Questions
What is a parapet wall?
It's the part of an exterior wall that extends above the roofline. Because it's weather-exposed on multiple sides, it's typically the first masonry on a building to deteriorate.
Why do parapet walls fail first?
They take water and freeze-thaw on both faces and the top, with no roof to protect them. That triple exposure breaks down mortar and brick faster than anywhere else on the building.
Is a leaning parapet dangerous?
Yes. A leaning or loose parapet can shed brick onto the sidewalk or collapse. It's a safety issue and should be evaluated promptly, not left through another winter.
Can a parapet be repaired or does it need a rebuild?
If the mortar and coping have failed but the structure is sound, it can be tuckpointed and resealed. If brick is loose, spalling, or the wall is leaning, the section usually needs to be rebuilt.
