Recently encounter some issue with my window works My ID told me that due to the window length exceeded the HDB requirements and they need to have a civil professional engineer to endorse which cost me about $1.5k. Not trying to blame her but is it true that the window length cost us an issue ? We are moving in soon except the window still under pending. Overall except for this sad window issue , will still recommend this company as their responsibility and workmanship is still a thumbs up!!
