I thought re-sealing the window frame would be a quick afternoon job

Spending the whole weekend with a scraper

It started when I noticed a tiny, dark stain growing on the living room wall right under the window frame. It wasn’t huge, but it looked damp, and every time it rained, it seemed to get a bit darker. I went to the local hardware store and grabbed a couple of tubes of general-purpose silicone and one of those plastic silicone scrapers that cost about 2,000 won. I really thought I could just scrape off the old, cracked rubber, squeeze in the new stuff, and call it a day. That was my first mistake. The old silicone was stuck on like it was bonded at the molecular level, and my wrist started aching after just ten minutes of trying to peel it away from the aluminum frame.

The reality of cleaning the old mess

After an hour, I was still stuck on the first window. My living room looked like a disaster zone, covered in little rubber shavings and dust. I realized then that the scraping part is actually 90% of the work. If you don’t get the old bits off perfectly, the new silicone won’t stick, or worse, it creates an uneven lump that looks even more amateurish than the crack I was trying to fix. I ended up spending about 35,000 won on extra tools, including a proper metal blade scraper and some specialized solvent to help loosen the old adhesive. That was way more than the cost of the original silicone tubes. I just sat there on the floor for hours, thinking about how I could have just hired someone to do this for a couple hundred thousand won, but then I felt too invested to quit.

Why it feels so precarious

I’m on the 12th floor. Every time I had to lean out slightly to check the exterior side of the window frame, my stomach did a little flip. I’m not particularly afraid of heights, but when you’re hanging halfway out a window in a 20-year-old apartment complex, everything feels a bit rickety. The gaps I found on the outside were much larger than the ones inside. Some areas had cracks running deep into the concrete where the window frame meets the wall. A simple tube of bathroom silicone or window sealant really doesn’t feel like enough to stop a driving rainstorm, but I didn’t have the budget or the connections for a professional high-rise rope team. I ended up packing as much sealant as I could into the gaps and hoping for the best, even though I knew the professional guys would have used a specialized backer rod or a different grade of heavy-duty urethane sealant.

The inconsistent finish

By the time I finished the last corner, the sun was already setting. My arms were shaking, and my clothes were covered in white smears that didn’t want to come off. The finish looks okay from a distance—definitely better than the cracked, peeling mess from before—but up close, it’s a bit messy. I didn’t use enough masking tape in the beginning because I was impatient, so there are little jagged edges where the silicone smeared onto the glass. It’s not professional, and honestly, I’m still not 100% sure I sealed the exterior gaps well enough to stop a heavy typhoon.

Lingering uncertainty about the rain

It’s been a few weeks since I finished, and we’ve had a couple of light drizzles. So far, no new damp spots on the wall, so maybe I got lucky. But every time the wind picks up and the rain starts hitting the glass horizontally, I find myself staring at that corner of the wall. I still wonder if the moisture is just waiting for a bigger storm to find its way back in. It’s a strange feeling, knowing you put in all that effort but still feeling like the house might be slowly deteriorating from the outside in. I don’t feel a sense of accomplishment, really. I just feel like I bought myself some time, and eventually, I’m probably going to have to deal with it again, only this time I might just pay the pros to do it right.
