Inspecting window seals after renovations is a vital step in ensuring the integrity of your exterior walls and preventing water damage. Window flashing is the material used to cover the joints where windows and doors meet the wall, and it plays a critical role in keeping water out. However, during renovations, the flashing can be damaged or dislodged, compromising its effectiveness.

Before you start the inspection, make sure you have the required tools and safety gear. This should include a ladder, gloves, safety glasses, and a flashlight. It's also a good idea to check the weather forecast to determine the best time for the inspection, ideally on a clear day without inclement weather.

The first step in inspecting the window flashing is to visually inspect the joints around the windows. Check for any signs of wear, shattered glass pane such as cracks, rips, or gaps. Look for loose or dislodged flashing, and take note of any areas where the flashing is not properly seated.

Next, use a putty knife or a similar tool to gently pry up the flashing and inspect the area underneath. Check for any signs of water damage, such as rot or rotting wood. This can be a sign that the flashing is not doing its job, and you may need to replace it.

After inspecting the flashing, check the sealants and cements used to secure it. Make sure they are not disturbed or weakened, and reapply them as needed. You should also check the caulk around the joints, ensuring it is not cracked or missing.

If you find any disturbed or missing flashing, it's essential to replace it as soon as possible. This may require some additional effort, such as repairing or replacing the surrounding wall. However, fixing the issue now can save you a lot of money and headache in the long run.

Finally, it's a good idea to inspect the flashing on a regular basis, especially after severe storms events. This will help you catch any issues before they become major problems. By following these tips, you can ensure that your window flashing is doing its job, and your exterior walls remain safe and secured.
