We just neutered Jack (at 8 1/2 months old) because he was marking everywhere. I can happily say after he was neutered for approximately 2 weeks, he stopped marking in the house. I did use a product on the areas that he used to mark to get rid of the urine, but he is using the puppy pads religiously! I couldn't be happier and so glad I had him neutered. Not to mention going for walks has been wonderful as he doesn't want to stop every two feet to mark his scent.
