What flashing work does for a Chicago building
Flashing work helps direct water away from places where masonry meets another material. These areas include roof edges, chimneys, parapet walls, windows, doors, and wall joints. Flashing may use metal, membrane, or another weather-resistant material. When it works well, rain and melting snow move away from the building instead of entering the wall.
Many property owners only notice a flashing problem after water reaches the interior. You may see a ceiling stain, damp wall, peeling paint, or a musty smell. Water can also enter behind bricks without leaving an early visible mark. That hidden moisture can weaken mortar, damage insulation, and cause interior repairs.
Chicago buildings face a special challenge. Freeze-thaw cycles cause water to expand and contract inside small cracks and open joints. Over time, this movement can loosen flashing, crack mortar, and damage bricks. Good flashing work helps keep water out before the problem spreads.
At Casey Tuckpointing, we have repaired and restored masonry in Chicago and nearby suburbs since 1994. We are a family-owned and operated company. We bring European craftsmanship and modern masonry methods to each project.
Signs that your flashing may need repair
Flashing problems do not always look the same. A small opening near a roof or window can allow a large amount of water into a wall during heavy rain. Look for these signs:
- Water stains near ceilings, windows, or exterior walls
- Damp spots or peeling paint after rain
- Cracked or missing mortar near rooflines
- Rust marks below metal flashing
- Loose flashing around a chimney or parapet wall
- Bricks that chip, flake, or show white mineral deposits
- Gaps where the roof meets a masonry wall
- A leaning or damaged chimney cap
- Drafts or moisture near glass block windows
- Repeated leaks after another contractor made a roof repair
A wall may also show bulging bricks or long cracks. These signs need a careful inspection. The cause may involve flashing, mortar, a rusted lintel, coping, or more than one issue. Replacing visible sealant alone may not solve the problem.
We inspect the full area before we suggest repairs. Our goal is to explain what we find and separate needed work from optional maintenance. Property owners can also review our guide to maintaining Chicago brickwork for more ways to watch for damage.
Common areas that need flashing work
Chimneys and roof edges
Chimneys take direct exposure from rain, snow, wind, and ice. Flashing around the chimney base must connect properly with the roof and masonry. If it pulls away or rusts, water can enter the attic or wall. Damaged chimney mortar can make the problem worse.
Our Chicago masonry services include chimney repair, rebuilding, mortar repair, and related waterproofing work. We can inspect the chimney, identify the source of the leak, and explain the repair plan in plain language.
Parapet walls
A parapet is the short masonry wall that rises above a roof. It protects the roof edge but receives heavy weather exposure. Coping, caps, and flashing at the top must shed water correctly. Broken joints or loose caps can send water into the wall and roof system.
Parapet repair may involve removing damaged mortar, replacing bricks, rebuilding a section, or correcting the flashing. We also handle professional waterproofing services when sealing forms part of the repair plan.
Windows, doors, and lintels
Flashing around openings keeps water from entering behind the brick. A failed seal, rusted lintel, or cracked mortar joint can create leaks above a window or door. Rusted steel can expand and push the surrounding masonry out of place.
The repair may require lintel work, brick replacement, mortar repair, caulking, or new flashing. We look at the whole opening instead of treating only the stain inside the building.
Coping and wall caps
Coping covers the top of a masonry wall. It should move water away from the wall face. Cracks, open seams, or missing seals can allow water to soak into the masonry below. Chicago winters can then worsen the damage.
A proper repair may include resetting coping stones, replacing damaged sections, sealing joints, and improving water flow. The right method depends on the wall material and the condition of the existing work.
How we approach flashing work
We start with a visual review of the exterior and interior areas connected to the leak. We check mortar joints, bricks, roof transitions, coping, chimneys, lintels, and nearby sealants. We also ask when the leak appears and whether another repair took place before it started.
Next, we explain the likely source. Water can travel inside a wall, so the wet spot inside may not sit directly below the exterior opening. We do not promise a simple fix until we understand the path water may take.
Our repair process may include:
- Removing loose mortar, failed sealant, or damaged masonry
- Checking the condition of the wall and supporting materials
- Repairing or replacing damaged flashing when needed
- Repointing open joints with suitable mortar
- Replacing cracked or spalled bricks
- Repairing coping, lintels, chimneys, or parapets
- Applying approved waterproofing or chemical sealing when appropriate
- Cleaning the work area and reviewing the finished repair
We do not subcontract our masonry work. Our family business gives you one point of contact and personal accountability. We are licensed and fully insured, and we handle permits when the project requires them. For larger buildings, we can also help with inspections, documentation, and code violation repairs.
Flashing work costs in Chicago
The cost depends on access, materials, the size of the damaged area, and the work behind the flashing. A small repair near a window differs from a full parapet or chimney repair. We provide a free estimate after reviewing the property.
For general planning, HomeGuide reports that typical residential waterproofing or sealing costs $200–$800. HomeGuide also lists chimney tuckpointing or repair at $150–$1,000, depending on the scope. These figures are general guides, not a quote for your building.
Other connected repairs may affect the total:
- Tuckpointing: $500–$2,500 for a typical residential job, according to HomeGuide
- Tuckpointing: $5–$25 per linear foot, according to Angi
- Brick repair: $700–$2,000 for minor to moderate damage, according to HomeGuide
- Parapet wall repair: $500–$5,000, depending on the extent, according to HomeGuide
- Lintel replacement: $300–$700 per lintel, according to Angi
These prices show why a site review matters. A low-cost patch may not address a failed wall joint or rusted support. Early repairs can also help prevent larger masonry and interior water damage. We give straightforward recommendations without pressure or unnecessary work.

When to call for an inspection
Call when you see repeated leaks, loose masonry, rust stains, or damage near a roofline. You should also schedule a review before buying or selling an older brick building. A property manager should act quickly after a tenant reports water entry or after receiving a city notice.
Do not wait for a small leak to become a large interior repair. Water infiltration through deteriorated mortar joints is one of the leading causes of structural damage in brick buildings, according to the Brick Industry Association. A qualified inspection can identify whether the issue involves flashing, mortar, bricks, coping, or structural supports.
