wondering if anyone encounter this problem before. the doors will curl inwards causing the center portion to protrude out slightly. the carpenter said its bcos these days, most of the wood used are young woods (abt 20 yrs old). so its not completing dry. therefore, after installation, the wood will continue to react to the environment. hence, it some of the doors will start to curl after exposing to eg : sunlight. this happen to few of my kitchen cabinet door & my wardrobe door. i m not sure if this is true or the carpenter is just smoking me. anyone have any ideas? TIA.
