Understanding Thru-Wall Flashing and Lintel Systems

Flashing and lintels are critical components within masonry structures — especially above windows, doors, and structural transitions.

Thru-wall flashing is designed to direct water out of the wall system, preventing moisture from becoming trapped within the structure. Lintels provide structural support above openings, carrying the load of the masonry above.

When these systems fail, the effects are often hidden — leading to water intrusion, structural damage, and long-term deterioration of the building.

At Heritage, we specialize in repairing and restoring these systems using proper masonry and restoration techniques — not surface-level fixes.

Not Roof Flashing — Structural Masonry Systems

There is often confusion around the term “flashing.”

We do not perform roof or chimney flashing work.

Our focus is on thru-wall flashing systems within masonry structures, including:

* Flashing above windows and doors

* Transition points between building sections

* Integrated moisture management systems within walls

Materials and Installation

Considerations

Flashing is typically made of metal, rubber, or waterproof membranes, while lintels are often steel or masonry units. Selecting the right materials and installation methods ensures that each repair withstands Southern Wisconsin’s climate, including freeze-thaw cycles and heavy precipitation.

Our team evaluates existing masonry conditions and determines the appropriate flashing and lintel solutions. Proper installation prevents water from entering walls, maintains structural stability above openings, and extends the lifespan of the building’s exterior.
