Leaking window when it rains
I live in Ontario, Canada, and like lots of other people, are in a heavy rainfall warning today. We had all new windows installed in our house about 8 years ago and this one window has given us grief ever since, in my son's room. Today, the rain was pelting on his window and we realized that his carpet was starting to get wet. It was also leaking down into our basement and almost started a fire from water dripping on a power bar. I went outside and noticed that there was no exterior caulking on the sides of the windows. Is this common? I would think that with rain and wind, rain could come in between the window and siding.
Can anybody tell me what to do. I think I need to caulk all around the window outside, remove the window trim inside plus the gyprock, rug and foam backing in case of mould.
As you can tell, I am very frustrated about this. Any help on this issue would be greatly appreciated.
