Sometimes, however, the weep holes get blocked by a build-up debris and dirt or the weather stripping around the window might need to be replaced.

Another potential culprit of water leaks is the lintel, which is a support for the brick that is above the window. The people who built the home may not have been aware that this lintel should be allowed to drain properly or they could have just clad it with concrete leaving gaps that allow rainwater to get in and build up around the window, causing dampness in the wall or rot in the wood. The installers could have bent fascia boards over the windows to ensure that water is directed correctly. This will stop water from getting into the building.
