How to estimate aluminum window costs in India (2026 guide)

If you are quoting an aluminum window project in India, six numbers drive 90% of the price. Get these right and the rest is rounding error.

1. Frame profile and series

Common series: Domal, Schuco, Eternia, Aluplex, Jindal. The price gap between an entry domal and a Schuco thermal-break can be 3x. Decide the series before measuring — don't guess later.

For mid-market residential work in 2026, expect roughly:

• Normal anodised: ₹220–280 per running foot of section
• Powder coated (white/ivory): ₹250–320
• Thermal break (low-E ready): ₹650–900

Prices vary by city and supplier load. Always confirm with your local dealer before quoting.

2. Glass

Glass is usually the single largest line item. The variables:

• Thickness: 5mm, 6mm, 8mm, 10mm, 12mm
• Type: clear / tinted / reflective / Low-E / tempered
• Configuration: single / double-glazed (DGU) / laminated

A 6mm clear sheet is the cheapest base. Going to 6mm tempered Low-E DGU for a high-rise can triple the per-sqft glass cost.

3. Hardware

Often missed in first quotes:

• Multi-point locks (typical for sliding & tilt-turn)
• Friction stays, hinges, handles
• Rollers (for sliders — heavy-duty vs standard)
• Gaskets and EPDM

Budget ₹400–1,200 per panel depending on whether you are using imported (Sobinco, Roto) or domestic hardware.

4. Labor

Fabrication labor varies widely by city. Typical rates:

• Tier 1 (Mumbai, Delhi, Bangalore): ₹35–55 per sqft
• Tier 2: ₹25–40
• Tier 3 and rural: ₹18–30

Add installation labor on top (usually 30–50% of fabrication).

5. Mesh, transport, wastage

Easy to forget:

• Mosquito mesh (where required): ₹35–60 per sqft
• Transport (per truck or per site visit)
• Wastage: budget 8–12% on sections, 5% on glass

6. Margin

Industry standard for fabrication contractors in India is 18–28% gross margin on residential and 12–20% on volume commercial work.

Common quote mistakes

The fastest way to lose money is to forget hardware, mesh, or wastage on the first quote and then absorb it.

• Skipping wastage entirely (loses ~10% margin instantly)
• Quoting at base section rate without checking current supplier price
• Treating fabrication labor as fixed when site complexity (high floors, restricted access) doubles it
• Forgetting GST when comparing your quote to an exempt informal one
