"Previous homeowners bricked over the only (tiny) access point to the crawlspace. It’s been super fun trying to fix copper plumbing lines they ran under the house, up an exterior wall to the 2nd floor laundry. Every winter they freeze a few times. There’s supposedly a heating line on them but I expect it’s no longer working.

I’m using next weekend to pull out the floor in the back stairwell to create a new access point so I can get under and see what’s happening. I dread going into the crawlspace, been here for 7 years and I have no idea what to expect"
