We had our home built in 2008 by a national builder. We have a 5 year leak warranty. Recently, I noticed during some rain storms that there is window leaking through from the outside what appears to be underneath the window. Depending on the rain 'force' sometime the water actually drips to the floor, but I've never had a true puddle. A picture of this is attached.
There are 2 windows, both are at least 3 feet from grade and one is probably 6 feet from grade, so the water is not pooling outside, simply driving rain or rain coming from down the siding.
I've reported this to the builder for warranty claim and they are indicating this is 'homeowner maintenance' and I need to reseal the window. I have the option to escalate the issue to arbitration, but I'm wondering if this is indeed a problem that can be completely and correctly resolved with sealant.
I'd appreciate any advice - Thanks!
