Thanks for the email address. I spoke to someone there this morning who put a stop to the bricking until the problem was fixed. I've included a before and after picture. You mentioned you had some holes that were fixed. I would say this was more than a hole
Here's the fix, which wasn't the greatest job I've ever seen.
Our house was built in the factory so the guy at the Trailer also directed me to someone in charge who I hoped would be able to explain why that was cut out. He could not give me any explaination however, which I find rather alarming. He actually tried to say it may have been the wind.
