DIY with doorknob replacement and silicon caulking

⌛Time it takes to read this article: < 1 minutesHere are two DIYs I did during the new year. [Doorknob replacement] The doorknob in my bedroom was broken, so I purchased a doorknob from Rakuten and replaced it. At first, I thought of hiring a contractor, but since it was early in the new year and I couldn't bear the expense of around 20,000 yen, I decided to fix it myself. The doorknob I purchased was a little small, but the installation was successful. However, unfortunately the strike of the metal fittings was too small, so I decided to use the current metal fittings as is. This cost me about 4,000 yen including shipping. [Silicon Caulk] Condensation has become intense due to the large-scale repair work that was carried out in my apartment last year, in which the aluminum sash was replaced. The silicone caulking on the bottom edge of the aluminum sash was thin and condensation was noticeable, so I used tools (caulking gun, masking tape) bought at a home improvement store to strengthen the silicone caulking. The paint came off when I removed the masking tape, so I plan to repaint it later. Condensation still occurs, but it seems to be better than before.
