I have a window in my house that leaks at the bottom corner. What can I do to find out where the leak is coming in from ? The caulking looks fine, the window is 7 years old, could it be a defective window ?
Answer:
No matter how good the caulking compound looks, you'll have to start by checking it more closely. At seven years, a window has already proven that it was not defective but caulking breaks down in rather short order or it can take many years.
