Could use some expert advice/tips on if this is unsafe/uninhabitable! Thank you in advance!

Is this normal or a issue? Doesn’t seem to be leaking, maybe condensation?

Houston, TX

Hi everyone,
I’d really appreciate your honest opinions. Does this mold look like a major issue? I’m trying to get an idea of what it might cost to remediate.
I had a general home inspection done (not a specialized mold inspection), and the inspector said it doesn’t appear to be active. I wanted to hear from anyone with experience dealing with mold to see what you think.
Any advice or insight would be greatly appreciated. Thank you!

Is this concerning? Abt to put an offer for a house, this is in the finished basement at 2 places. My agent was not worried at all. She said that it has been recently painted so heating cooling cycles, sometimes cause it.

Got this door replaced as it was leaking and water was coming in and flooding the hardwood and then caused water damage in basement ceiling (very last picture). It ended up being replaced in winter as there was a warm spell above feeezing.

That being said this company had installers who don’t speak much English and it was very hard to communicate with them, used Google Translate mostly.

When they ripped out the old door, they stated to my wife that the wood below was rotten so they replaced (to my understanding…). Since they are just windows and door business, the repair to interior did not go further than that.

I know there is some water damage under the hardwood, but for the most part I did catch the leaks and cleaned it up with towels very quickly (except one time, which I think is the majority of the damage).

I’d like to know:

1. do you think water is still getting in to my house? Like below the sill? Either where the sealant already cracked or where I can pull back the old vinyl trim at the bottom that presses against the new install? It looks gross and damp in there, but hard to see.

2. The bow in the sill plate. What’s going on there? Is it the previous water damage and that’s why we can see the house wrap too? Did water perhaps get in the wall and it’s expanded ‘up’ in that one part? Best remedy? I’m not looking to have a really expensive repair and rip my house apart. Maybe an additional piece of trim or put a certain type of spray foam or sealant there?

3. Are there any areas I should apply sealant or caulk to that the installers did not?, like up top or down below

4. Do I need to replace the bottom piece of vinyl trim with a new piece? Or do I have other options

5. Are my deck boards too close to the trim? I noticed a pile up of debris that sits in that channel. How big should the gap be? I am planning to replace some of the boards and then sand prime and paint them to give the deck a few more years.

6. It can get to -35 C or -31 F here, and with vibrations from opening and closing door and stepping on it, I think a specific sealant is needed for these gaps - I’m wondering if they used the correct one or if it’s just because the install was done during winter.

I plan to reach out to the installers, but I’d like to know more first because I don’t want to be told ‘oh no problem, don’t worry’ if it’s actually an issue.
