Hi all, I'm looking to repair 2 things in my flat: 1) the aircon frame outlet in the master room. Previous owner has an aircon unit installed but this was removed when she shifted out. My ID sealed up the area but with wood planks and cement. After staying for 8 years, there is water seepage during rainy season and the inside wall started peeling. 2) door frame for main door - basically it's old and my family wants to refurbish it Any good & reliable contractors to recommend for these 2 repairs? Must be approved by HDB and not pricey. Thank you!
