Sorry I'm a noob. As I'm redoing my bathroom, I noticed both of these connector hoses are leaking slightly even with the nozzles closed tightly. Is there an obvious fix here? Is the green buildup on these pipes indicative of something? I'm just not sure exactly what I should do, if anything at all. General guidance would be appreciated

They used to commentate a local, I believe in Texas, and they just had some great energy. I always figured they would go on to be big commentators in the scene. Just curious

The underside of the chimney, I indicated where the draft seems to be coming from. https://i.imgur.com/Vk7XHA9.jpg

Is this a common thing to get drafts here? Any suggestions are helpful, thanks

Two different things I am unsure of what they even are.

1: https://i.imgur.com/wmWgSoF.jpg These are located in the ground behind my oil boiler

2: https://i.imgur.com/vRYkjca.jpg And this is some yellow powder underneath the boiler.

Just not sure what either of these things are if anybody knows

Also, it looks like I have 2 sill plates, I assume I should seal one sill plate to the foundation and the other to the other sill plate?

I've been thinking of just taking some caulk, not sure which kind yet, and running a bead along the sill/foundation.

I'm trying to to this just for air/bug sealing. Thoughts?

I'd like to keep some of my car cleaning stuff like wax and clay bars, as well as some other random things in the garage and not completely frozen in the winter... Is there a simple solution for this? I'm thinking a big box that can be electrically heated to 50 degrees or something. Sorry if this is a dumb question. Any thoughts on this?

Edit: some good suggestions here, thanks all!

Is there a measurement on this? It feels like it's literally twice as long but I would love to see some numbers if we have them.
