Rontan 0 Report post Posted September 22, 2015 I just confirmed with an ID and will be starting reno for a resale flat in Oct. I am quite worry when my ID said window installation will be the last to do and he insist he know his work better. Can someone please enlighten me as from what I know replacing window will affect the tiling of toilet and kitchen. Shouldn't changing of window be done before the tiling of kitchen wall and toilet wall? Share this post Link to post Share on other sites
