Your building’s façade does more than make a first impression—it protects the structure from the elements, supports energy efficiency, and plays a key role in occupant safety. But like any exterior surface exposed to Chicago’s freeze-thaw cycles, rain, and pollution, even the most durable materials can show signs of wear over time.
Knowing when your building needs facade repair can help prevent minor issues from turning into major structural problems. At Corona Craft Restoration, we’ve helped restore countless commercial, multi-unit residential, and historic buildings across the city. Here are six key warning signs to look for.
1. Cracks in Masonry or Concrete
Cracks in your brickwork, stone, or concrete aren’t just cosmetic—they’re one of the earliest signs that your façade may be under stress. Small vertical or horizontal cracks can signal movement in the structure, while diagonal or stair-step cracks could point to foundation issues.
Regardless of size, cracks compromise water resistance and can allow moisture to seep into the wall, accelerating damage. A professional façade inspection is the best way to assess the severity and determine the right repair strategy.
2. Missing or Deteriorating Mortar
If you notice gaps, crumbling mortar, or joint erosion, it’s a clear sign your masonry is weakening. Mortar holds the entire structure together—and when it begins to fail, water infiltration becomes a real risk.
Tuckpointing can be used to restore the mortar joints, but if the deterioration is widespread, more extensive facade repair may be needed to prevent long-term issues.
3. Spalling or Flaking Brick
Spalling occurs when moisture gets trapped in the brick, freezes, and forces the surface to break away. This can lead to crumbling bricks, surface discoloration, and compromised structural integrity.
Not only does this diminish the look of your building, but it’s also a sign that water is already affecting deeper layers of the façade.
4. Water Stains or Leaks Inside
If you’re seeing water stains on interior walls or ceilings—especially near windows or along the perimeter—it could be coming from a failed façade system. Deteriorated sealants, cracks, or open mortar joints can allow moisture to breach the building envelope.
Facade repair, along with proper caulking and sealant services, can help restore a watertight exterior and protect the building’s interior.
5. Loose or Bulging Materials
Any areas of the façade that appear to be bulging, bowing, or separating from the structure can be extremely hazardous. This may be caused by rusting support anchors, water damage, or settling foundations.
This isn’t just a matter of aesthetics—loose materials can fall and create serious safety concerns for tenants and pedestrians. Immediate evaluation and facade repair are essential.
6. Outdated or Failing Sealants
Sealants around windows, joints, and expansion points break down over time due to UV exposure and temperature fluctuations. Cracked or missing sealant can allow water and air to infiltrate the wall system, leading to energy loss, mold, and further façade degradation.
A comprehensive façade inspection can identify areas where re-sealing or joint repair is necessary.
