Why it matters
Resale flats often have hidden floor conditions. Covering the old floor without review can create noise, movement, gaps or raised joints later.
Old tiles can change the result
A resale floor may look acceptable but still have loose tiles, uneven support or hidden moisture concerns. A rigid SPC floor needs the surface below to be stable enough.
Hollow areas can become sound or movement problems.
Uneven floors can stress the click-lock edge.
Door thresholds can expose height issues after installation.
The quote should show the assumption
A resale HDB quote is only useful when it says what the current floor condition appears to be and what still needs site confirmation.
Ask whether preparation is included or excluded.
Confirm trims, skirting and transitions before work starts.
Keep photos and accepted scope for handover records.
