Fixing a Bay Window Leak in a 13-Year-Old Home in Northville, Michigan

Bay windows are a beautiful feature in any home, but they can be a tricky spot when it comes to water leaks. In this 13-year-old Northville, Michigan home, a persistent leak had begun to damage the ceiling beneath a bay window, prompting a careful inspection and repair.

Identifying the Problem

Upon inspection, the culprit was clear: poor flashing. Flashing is the waterproof material installed around windows and other roof penetrations to prevent water intrusion. Over time, improper installation or wear and tear can cause gaps, allowing water to seep in. In this case, the flashing around the bay window had failed, letting water enter and damage the interior ceiling.

Step 1: Preparing for Repair

The first step in the repair process was removing any damaged caulk, sealant, and debris around the window. This step is critical because new flashing and caulk can only adhere properly to clean, dry surfaces. Once the area was cleared, the team assessed the full extent of the flashing failure.

Step 2: Installing New Flashing

New flashing was carefully installed around the bay window, making sure it was properly integrated with the siding and roofline. Proper flashing ensures that water is directed away from the window rather than behind it. Special attention was paid to overlapping and sealing the joints without blocking weep holes, which are essential for drainage.

Step 3: Sealing and Finishing

Once the flashing was in place, high-quality exterior caulk was applied to seal all edges and seams. Inside the home, any water-damaged drywall and paint were repaired to restore the ceiling to its original condition. The team then performed a water test, using a hose to simulate rainfall, confirming that the leak had been fully stopped.

Why This Matters

Fixing a bay window leak promptly is crucial to prevent further damage such as mold growth or structural deterioration. Regular inspection and maintenance of flashing can save homeowners from costly repairs in the future.

This repair in Northville demonstrates the importance of proper installation, attention to detail, and timely action. With the right approach, even a 13-year-old home can be protected from leaks and water damage, keeping both the structure and interior looking great for years to come.
