How Much Does Window Replacement Actually Cost in the Philippines?
Not a guess. Not a "starting at." These are real prices from completed 2026 projects — broken down by every component so you know exactly where your money goes.
"Magkano po ang window?" — we answer this question 30 to 50 times a day. And every time, we wish the answer were simpler. The truth is that window replacement costs in the Philippines range from ₱2,500 per square meter (basic jalousie) to ₱14,000 per square meter (double-glazed insulated) — a 5x difference — and the reason is that a "window" is actually five separate purchases bundled together: aluminum frame, glass panel, hardware, sealant, and labor. Change any one of those five and the price shifts dramatically. Here is the honest, line-by-line breakdown.
The Quick-Reference Price Table
If you just want the numbers, here they are — cost per square meter of window area, fully installed, including all materials and labor:
| Window Type | Aluminum Series | Glass | Cost/SQM (Installed) |
|---|---|---|---|
| Jalousie (louvre) | Series 38 | 6mm clear | ₱2,500 – ₱3,500 |
| Sliding (standard) | Series 798 | 6mm clear | ₱3,500 – ₱5,000 |
| Sliding (heavy-duty) | Series 900 | 6mm tempered | ₱5,500 – ₱7,500 |
| Casement | Series 79 | 6mm tempered | ₱4,500 – ₱6,500 |
| Awning | Series 79 | 6mm tempered | ₱5,000 – ₱7,000 |
| Fixed picture window | Series 798 | 10mm tempered | ₱4,000 – ₱6,000 |
| Sliding + acoustic glass | Series 900 | 6.38mm laminated | ₱7,000 – ₱10,000 |
| Casement + double-glazed | Series 79 | 6+12+6mm IGU | ₱10,000 – ₱14,000 |
Why the range on each line? The lower end assumes mill-finish aluminum (raw silver color) and clear glass in a straightforward concrete opening. The upper end includes powder-coated frames (any color), tinted or tempered glass, complex rough opening preparation, and locations with difficult access (upper floors, narrow alleyways).
Breaking Down the Cost: Where Your Money Actually Goes
Most contractors give you a single lump-sum number. We think that is dishonest because it hides where the quality corners are being cut. Here is what each component actually costs for a standard 1200mm × 1000mm sliding window (Series 798, 6mm tempered tinted glass):
| Component | Cost | % of Total | What to Watch For |
|---|---|---|---|
| Aluminum extrusions (frame) | ₱1,800 – ₱2,500 | 35-40% | Series number and gauge thickness (1.2mm minimum) |
| Glass panels (2 panes) | ₱1,200 – ₱1,800 | 20-25% | Tempered vs annealed — look for the corner stamp |
| Hardware (rollers, lock, handle) | ₱600 – ₱1,200 | 10-15% | Branded vs generic — affects daily operation for years |
| Weatherstripping | ₱150 – ₱300 | 3-4% | Double wool-pile vs single — affects air and water sealing |
| Sealant (perimeter) | ₱200 – ₱400 | 3-5% | Structural silicone vs cheap acrylic (fails in 1-2 years) |
| Mosquito screen | ₱400 – ₱700 | 5-8% | Fiberglass mesh vs nylon — fiberglass lasts 3x longer |
| Installation labor | ₱800 – ₱1,500 | 12-18% | Includes old frame removal, installation, sealant, testing |
| Total per window | ₱5,150 – ₱8,400 | 100% |
The lesson: Aluminum and glass together account for 55 to 65 percent of the total cost. This is where cheap contractors cut corners — using thinner gauge aluminum (0.8mm instead of 1.2mm) and annealed glass instead of tempered. The savings are real — roughly 30 to 40 percent cheaper — but the window will fail in 3 to 5 years instead of lasting 15 to 20.
Real Project Costs — Completed 2026 Projects
These are not estimates. These are final invoiced amounts from GlassInstallerPH projects completed between January and June 2026 across Metro Manila, Calabarzon, and Cebu:
| Project Type | Windows | Specification | Total (Installed) |
|---|---|---|---|
| Studio condo (BGC) | 2 sliding | Series 798, 6mm tempered tinted | ₱18,000 – ₱28,000 |
| 1-BR condo (Makati) | 3 sliding | Series 798, 6mm tempered tinted | ₱25,000 – ₱40,000 |
| 2-BR condo (Ortigas) | 4-5 sliding | Series 798, 6.38mm laminated | ₱45,000 – ₱70,000 |
| Townhouse (Cavite) | 6-8 mixed | Series 900, 6mm tempered tinted | ₱55,000 – ₱95,000 |
| Subdivision house (Laguna) | 8-10 mixed | Series 900, casement + sliding | ₱75,000 – ₱130,000 |
| Custom build (Batangas) | 15-20 mixed | Series 900, tempered tinted | ₱150,000 – ₱280,000 |
| Whole-house premium (QC) | 20+ mixed | Series 1200, double-glazed | ₱280,000 – ₱500,000 |
All prices include materials, fabrication, installation, old frame removal, debris disposal, sealant, and post-installation hose testing. Condo projects include building management coordination. Prices exclude wall repainting after frame removal (painting contractor's scope).
The Aluminum Series — Why It Is the Biggest Cost Driver
The aluminum series determines the frame's structural strength, typhoon resistance, and lifespan. It is also the single biggest variable in your total cost. Here is the honest comparison:
| Series | Gauge | Wind Rating | Best For | Lifespan | Cost Premium |
|---|---|---|---|---|---|
| Series 38 | 0.8-1.0mm | Low | Interior jalousies, budget temporary | 3-5 years | Baseline |
| Series 798 | 1.2-1.4mm | Moderate | Standard residential, condos | 8-12 years | +20-30% |
| Series 900 | 1.4-1.6mm | High | Typhoon areas, coastal, heavy-duty | 15-20 years | +40-60% |
| Series 1200 | 1.6-2.0mm | Very High | Commercial, large spans, premium residential | 20-25 years | +70-100% |
Our recommendation for most Philippine homes: Series 900. The 40 to 60 percent cost premium over Series 798 buys you nearly double the lifespan (15-20 years vs 8-12 years), significantly better typhoon resistance, and smoother daily operation due to the deeper track channels and heavier-gauge rollers. On a cost-per-year basis, Series 900 is actually cheaper than Series 798.
Glass Pricing — The Second Biggest Variable
| Glass Type | Thickness | Cost/SQM | Why Choose It |
|---|---|---|---|
| Clear annealed | 5-6mm | ₱600 – ₱900 | Budget only — dangerous breakage pattern |
| Clear tempered | 6mm | ₱1,200 – ₱1,800 | Minimum safe specification |
| Tinted tempered (bronze) | 6mm | ₱1,400 – ₱2,000 | Heat reduction 30-55% — best value upgrade |
| Laminated acoustic | 6.38mm | ₱2,200 – ₱3,500 | Noise reduction for highway-facing rooms |
| Low-E coated | 6mm | ₱2,800 – ₱4,500 | Maximum heat rejection (60-75%) |
| Double-glazed IGU | 6+12+6mm | ₱4,500 – ₱7,000 | Premium thermal + acoustic performance |
The smart upgrade: Going from clear annealed (₱600-₱900/sqm) to tinted tempered (₱1,400-₱2,000/sqm) costs approximately ₱800 to ₱1,100 more per square meter — but gives you safety glass that does not produce razor shards when broken, PLUS 30 to 55 percent solar heat reduction that directly cuts your monthly electricity bill. For a standard window (1.2 sqm), that is only ₱960 to ₱1,320 more. Most homeowners recover this through AC savings within 6 to 12 months.
Hidden Costs That Surprise Homeowners
Every month we meet homeowners who accepted the cheapest quote, then discovered these additional charges during or after installation:
| Hidden Cost | Amount | Why It Happens |
|---|---|---|
| Rough opening repair | ₱500 – ₱1,500/window | Old concrete cracked or uneven — not visible until frame is removed |
| Old frame removal | ₱300 – ₱800/window | Some contractors quote "supply and install only" — removal is extra |
| Debris disposal | ₱200 – ₱500/window | Old frames, glass, and packaging must be hauled away |
| Wall repainting | ₱500 – ₱2,000/window | Exposed concrete and paint damage around the old frame — separate trade |
| Condo work permit | ₱2,000 – ₱5,000/project | Building management processing fee — non-negotiable |
| Condo security deposit | ₱5,000 – ₱15,000 | Refundable after inspection — but you need the cash upfront |
| Coastal/marine premium | +10-15% on materials | Marine-grade powder coat and stainless hardware for salt air environments |
| High-floor surcharge | +10-15% total | Above 5th floor — elevator coordination, additional safety requirements |
Our policy: Every GlassInstallerPH quotation includes old frame removal, debris disposal, sealant, mosquito screens, and hose testing. The only items excluded are wall repainting (different trade) and condo-specific building deposits (refundable). No surprises.
How to Spot a Lowball Quote
If a quote seems too good to be true, it is. Here are the specific red flags:
No aluminum series specified — the quote just says "aluminum sliding window" without mentioning Series 798, 900, or any series number. This almost always means Series 38 (the cheapest, thinnest profile).
No glass type specified — the quote says "glass" without specifying tempered, annealed, thickness in mm, or tint. This almost always means 5mm annealed clear — the cheapest and most dangerous option.
"Per window" lump sum — no line-item breakdown of aluminum, glass, hardware, sealant, and labor. This makes it impossible to compare quotes because you do not know what is being priced.
No hardware brand mentioned — generic zinc-alloy rollers cost ₱80. Branded stainless steel tandem rollers cost ₱400 to ₱800. The cheap ones grind out within 2 years.
No sealant specification — the quote does not mention sealant type. Cheap acrylic caulk costs ₱50 per tube and cracks within 12 months. Structural silicone costs ₱250 to ₱400 per tube and lasts 15 to 25 years.
No warranty terms — a legitimate installer provides written warranty covering frame integrity, glass seal, hardware operation, and water leakage for a minimum of 2 years.
Payment Terms You Should Expect
Standard industry payment terms for window replacement in the Philippines:
| Milestone | Payment | What It Covers |
|---|---|---|
| Order confirmation | 50% | Material procurement — aluminum, glass, hardware ordering |
| Material delivery to site | 40% | Confirms materials arrived and match specification |
| Completion and hose test | 10% | Final payment after installation is complete and tested |
Never pay 100% upfront. The 50/40/10 structure protects you: 50 percent gets the project started, 40 percent confirms materials are correct, and 10 percent retention gives you leverage to ensure the installer completes cleanup, adjustments, and hose testing before receiving final payment.
