I just transfer in our new house. And same as you, I had experience that on my first day in our new house. There is a stinky smell which I cannot identified. It is really disgusting when I smell that unbearable odor. It will surely adds up to your mood for the whole day. Who wants to live in a home that smells bad? I'm sure no one! As this, I have read an article here. Well, it somehow help my problem. Thank God!
