If you are planning an invisible grill for your balcony or windows, the first question is usually: how much will it cost? The honest answer is that it depends on your space and the material you choose. This guide explains how invisible grill pricing works in Mumbai, what changes the final cost, and how to avoid paying for a cheap grill twice.
How invisible grill price is calculated
Invisible grills are almost always priced per square foot of the area being covered. To work out your area, multiply the height by the width of the opening. For example, a balcony opening 10 feet wide and 4 feet high is 40 sq ft.
Most online listings for Mumbai show standard installations at roughly ₹95 to ₹150 per sq ft, with premium wire, special layouts or difficult access costing more. Treat these as a starting point only. The real price comes after someone measures your site.
What changes the cost
- Wire grade: SS 316 marine-grade wire costs more than SS 304, but it resists rust far better in Mumbai’s salty, humid air. See our guide on SS 304 vs SS 316 wire.
- Wire thickness and coating: nylon-coated wire adds protection and a smoother finish.
- Wire gap: a closer gap for small children or pets means more wire per sq ft.
- Track and fittings: a heavier aluminium track and stainless steel fasteners and stiffeners add strength, especially on large terraces.
- Size and access: very small areas may have a minimum charge, and high or hard-to-reach openings take more time.
- Fixed vs removable: removable grills need extra hardware.
Why the cheapest quote can cost more
A low quote often means thinner wire, a lower steel grade, plain steel screws or a light track. These can rust, sag or loosen within a few monsoons, and then you pay again for a replacement. When comparing quotes, ask:
- What grade of steel is the wire (304 or 316)?
- Is the wire nylon-coated?
- What is the tensile strength per wire?
- Are the fasteners and stiffeners stainless steel?
- Is installation by the company’s own team?
- What warranty do you give, and on what?
How to get an accurate quote
The easiest way is a free site visit. A technician measures every opening, checks the wall and railing, and suggests the right wire, gap and track. You then get one clear price for your exact space, with no surprises later.
