11 May The 2026 Guide to Invisible Grille Costs in Singapore
Planning to secure your new BTO or balcony? While safety is priceless, your budget isn’t. Here is exactly what you can expect to pay for invisible grilles in Singapore this year.
Breaking Down the Price per Square Foot
In Singapore, most installers quote based on square footage. On average, you can expect to pay between $7 to $15 per square foot (psf).
What Influences the Final Bill?
-
Material Grade: 316 Marine-grade stainless steel is the gold standard for rust resistance and carries a slight premium over 304 grade.
-
Cable Thickness & Gaps: A 2-inch gap (common for pet owners) requires more material and labor than a standard 3-inch or 4-inch gap, slightly increasing the cost.
-
Frame vs. Frameless: Fixed frames are generally more affordable, while casement (opening) or sliding invisible grilles involve more complex tracks and hardware.
-
HDB vs. Condo vs. Landed: Accessibility and height can sometimes affect labor costs, especially for high-floor units requiring extra safety scaffolding.
Bottom Line: For a standard 3-bedroom HDB balcony, a full installation typically ranges from $600 to $1,200, depending on your specific requirements.
