Window Installation & Replacement in Keat Hong Village

uPVC/vinyl is the value pick: good insulation, low maintenance, mid-range look. Aluminium gives slim frames and durability (thermally broken frames fix its insulation weakness) at a higher price. Timber looks best and suits period homes but needs maintenance and costs most. Warranty and installer quality matter more than brand marketing.

Windows are priced per opening: the unit itself (frame material, glazing spec, size) plus installation labour. A standard-size replacement in an existing opening is the base case; enlarging openings, upper-floor access, bay windows and heritage styles add meaningfully. Whole-house jobs get per-window discounts.

Per-window pricing with glazing spec, removal and disposal of old windows, making good internal reveals and external sealing, hardware, and warranty terms for both the unit (often 10 years) and the installation. Cheap quotes commonly exclude making-good — the messiest part.

Like-for-like replacement is usually permit-free, but many places regulate windows through energy codes, safety-glass rules, and egress requirements for bedrooms — and heritage/conservation properties almost always need consent for changes. Your installer should know local rules; ask what paperwork you'll receive at completion.

The sealed unit has failed and let moist air in. The fix is usually replacing just the glass unit, not the whole frame — a fraction of full replacement cost. Widespread misting across many windows of the same age suggests the batch is failing and full replacement may be better value.

Double glazing (two panes with a sealed gas gap) is the modern default. Triple adds insulation and noise benefits that matter most in cold climates and on noisy roads; elsewhere the extra cost rarely pays back. Spend first on installation quality and low-E coatings — a badly fitted triple-glazed unit performs worse than a well-fitted double.

Only BCA-approved window contractors — this is a licensing regime specific to Singapore introduced to stop fallen-window incidents. For HDB flats the contractor must also be HDB-registered, and facade appearance can't change without approval.
