Hi, my name is Michele. I am a mother, grandmother, widow, and a hard worker. Now that I'm on my own, I find all this home upkeep really challenging. Can't really call myself a DIY er, though I would like to beš!I don't have much experience with home projects, not much confidence, and can't afford to hire someone else to do it. But I'm willing to try, so I'm finding places like this one to help me figure things out. So wish me luck! I have a terrible smell in my house. It is intermittent, smells like sewage, or standing mucky water. I have crawled around under the house, all was dry. There are two pipes attached to the back of the house, one big, one smaller. Iām thinking these are some kind of vent pipes?? One has come apart, and looks plugged off by dirt dobber nest. Could this be my problem? I am attaching a picture. Thanks in advance for any advice šš
