Stucco flashing is an integral component of any building’s exterior envelope, providing protection against water intrusion and prolonging its longevity. Over time, however, stucco flashing may become worn down and need repair.
Stucco flashing serves a critical purpose: stopping water seepage into buildings that could result in structural damage, mold growth, and other costly problems. By diverting it away from vulnerable areas of a structure, stucco flashing plays a pivotal role in keeping its integrity.

When do you Need Stucco Flashing Repair?

Like any building material, stucco flashing is vulnerable to wear and tear over time, including extreme weather conditions, improper installation procedures, or neglectful maintenance practices. Here are some signs of stucco flashing damage:

  • Water Stains: Stains on interior walls or ceilings near windows and doors that appear as discolorations or dark spots can indicate issues with stucco flashing, such as discoloration or discoloration of stucco flashing.
  • Mold or Mildew Growth: If you notice mold or mildew growth on the stucco surface or surrounding areas, this could be a telltale sign that water intrusion caused by damaged flashing has penetrated it.
  • Cracked Stucco: Cracked stucco around windows, doors, or roof edges may indicate that flashing underneath has deteriorated or shifted significantly, signaling flashing needs replacement or repair.
  • Peeled or Bubbling Paint: Water entering through damaged flashing can penetrate stucco and cause its paint to peel or bubble, leading to its entrance into stucco walls and leading to leakage of moisture into it. This may result in peeling or bubbling paint.
  • Rotting Wood: If your flashing has failed to protect wood components such as window sills or door frames from moisture damage, signs of decay could appear over time.
  • Repairing Stucco Flashing: Proper stucco repair techniques must be followed when attempting to restore damaged stucco flashing.
  • Assess Damaged Areas: Conduct an initial inspection to ascertain the extent of stucco damage in its entirety, paying particular attention to joints between stucco panels and windows, doors, or roof edges that could potentially have become compromised.
  • Remove Damaged Flashing: We carefully use a pry bar or similar tool to carefully unhook any damaged flashing, taking precautions not to cause further damage to the stucco or adjacent building components in this process.
  • Thoroughly Clean the Area: Once all damaged flashing has been removed from its former home, we ensure a thorough cleanup in the area where we removed it by clearing away debris, dirt, or loose stucco so as to provide a suitable surface for new flashing to adhere.
  • Install New Flashing: We cut your new flashing material to fit the desired length and shape, making sure it tucks neatly against stucco walls while covering adjacent components. Securing it using fasteners such as screws or nails.
  • Seal Joints: Applying high-grade sealants such as silicone caulk to seal all joints between the flashing and stucco, to help prevent water intrusion into these spaces and ensure a watertight seal. This will also help ensure an airtight seal between these materials.
  • Reapply Stucco: If the repairs require the removal of significant portions of stucco, reapplying it may be necessary in order to match its texture and finish.
  • Paint and Finish: Once the stucco has been set, we restore its visual appeal with exterior paint or finish that matches its surroundings for additional weather protection and additional visual appeal. This will also protect it against external factors.
