The first sign of the leak
It started with a dark, damp patch appearing near the bottom corner of my living room window. I didn’t think much of it at first. I just assumed maybe someone had left the window cracked during the last rainstorm, but then it happened again. Every time it rained heavily, the paint would bubble slightly, and there would be this faint, earthy smell that I really couldn’t stand. I spent about an hour just staring at it, trying to figure out if it was coming from the actual glass seal or if it was leaking from the exterior wall itself.
Trying to handle the caulking myself
I decided to take matters into my own hands because I honestly didn’t feel like waiting weeks for a management office to send someone over. I went to the local hardware store and grabbed a few tubes of exterior-grade silicone sealant. I’ve seen those YouTube videos where people make it look so effortless, just slicing the old caulk off and laying down a perfect bead of new stuff. In reality, it’s a messy, sticky nightmare. Trying to balance on a small stepladder while holding a caulking gun and wiping away excess goop with a rag that kept falling to the floor was just exhausting. I think I spent roughly 30,000 won on supplies, which was cheaper than calling in a professional for an emergency, but my neck hurt for two days afterward, and the bead I laid down looks incredibly amateurish compared to what was there originally.
The realization about structural issues
After I finished the window, I noticed the ceiling in the boiler room looked a bit off, too. There was a faint ring of discoloration that looked like it had been there for a while. I started wondering if this was part of the larger issue with the building’s aging facade. I read somewhere that the Seoul Education Office is now prioritizing things like waterproofing and exterior wall repairs for older schools because they recognized that waiting too long just makes the whole repair cost balloon later on. It made me feel a bit better knowing that even large government buildings struggle with these exact same maintenance cycles. It’s not just my old apartment; concrete just doesn’t stay waterproof forever, I guess.
Considering the bigger picture
I spoke to a neighbor who had recently had their entire balcony caulking redone. They mentioned they spent about 800,000 won for a team to come in with specialized equipment. Hearing that number made me feel both relieved that I didn’t pay that much yet and worried that my 30,000 won patch job is just a temporary band-aid. The neighbor’s place still has issues with moisture in the storage unit, so it’s clearly not a perfect fix even when you hire experts. Sometimes these buildings feel like they are fighting a losing battle against the weather, especially with the way the humidity hangs around in the city.
Living with uncertainty
It’s been a few weeks since my DIY project, and there hasn’t been any heavy rain to truly test it. I find myself glancing at that corner every time the clouds turn grey. Part of me thinks it’s fine, but another part of me feels like I’m just waiting for the next leak to pop up somewhere else. I’m not sure if I’m waiting for the building management to eventually step in for a full-scale renovation or if I’m just going to keep buying more silicone. It’s a strange, lingering anxiety that comes with owning or managing a space that isn’t brand new. You stop seeing the house as a static object and start seeing it as a collection of parts that are all slowly needing attention, one after the other. I might end up calling an actual professional by the time the next season rolls around, but for now, I’m just watching the wall.

That silicone sealant really does look like a different world than those YouTube tutorials. I had a similar experience trying to patch a small crack – the control slipped, the mess was immense, and I ended up just covering it with tape.
