When the window frame started leaking during the monsoon

Dealing with the first signs of water

It started as a small, damp patch on the wallpaper just below the balcony window. I thought it was just condensation because of the humidity, but when the rainy season really hit, a literal trickle of water started running down the wall. It wasn’t enough to flood the floor, but it was persistent enough that I had to keep a dedicated towel there 24/7. My first thought was that I could just scrape off the old, cracking silicone and redo it myself. I bought a few tubes of generic sealant for about 15,000 won each from the local hardware store, thinking it was a simple weekend project.

The frustration of DIY trial and error

I spent an entire Saturday afternoon precariously balanced on a step stool, peeling away the black, moldy strips of the old seal. It looked easy in the videos online. In reality, the silicone wouldn’t peel off in neat lines; it just kept breaking into tiny, sticky fragments that got stuck to my fingers and the edge of the aluminum frame. After I finally finished the application, I felt proud until the next heavy rain shower arrived three days later. The water was still finding a way in, only now it seemed to be coming from a slightly different spot, which felt even more annoying than before. I had clearly missed a microscopic gap somewhere in the upper corner.

Looking at professional options

At this point, I started looking into actual building maintenance services. A neighbor mentioned that some of these local companies charge anywhere from 300,000 to 500,000 won depending on how many windows need attention. That felt like a lot for a few tubes of sealant, but then I watched a guy from a repair company working on the villa across the street. He was rappelling down from the roof like he was in a movie, sealing the entire exterior frame rather than just the interior side. I realized then that my little indoor DIY project was never going to solve the root cause, which was likely on the exterior side of the wall.

The uncertainty of a permanent fix

There’s this lingering doubt about whether the problem is actually the window frame or the building structure itself. I’ve read stories about people spending millions of won on professional repairs only to have a leak reappear in a different room the following year. It’s a constant trade-off between paying for a temporary fix and worrying that the entire building’s exterior might be failing. I’m currently just rotating towels and waiting for a dry week to see if I should just call one of those general repair services, but I’m still hesitant to pull the trigger. It’s hard to justify the cost when I’m not even certain it’ll stay dry for more than one season. Maybe I’ll just try the external tape method I saw on a forum, even though everyone says it’s just a stopgap measure.
