A window quote that’s only a per-square-foot frame rate leaves out the part that
decides whether the window leaks in the monsoon — the wall-frame sealing. In Thane,
where wind-driven rain finds every weak joint, that detail matters as much as the
frame itself. This guide breaks sliding window and grill cost down by type and explains
what a complete window rate covers.

_The figures here are indicative current market ranges for Thane and the wider MMR—
not Jyani’s quote — your exact cost depends on the window size, frame type, glazing
and finishing, and is confirmed only after a free site visit and a review of your
requirements._

## Cost by type

| Type | What it suits | Indicative basis | 
| Aluminium sliding (2-track) | Standard windows | ₹350 – ₹600 per sq ft | 
| Aluminium sliding (3-track/with mesh) | Better ventilation + mosquito mesh | ₹500 – ₹800 per sq ft | 
| UPVC sliding | Better sealing/insulation, premium | ₹600 – ₹1,200 per sq ft | 
| MS / SS grills | Safety grills (painted MS to SS 304) | ₹120 – ₹700 per sq ft |

## What’s in a complete window rate

A complete rate covers the **frame** (aluminium grade and section, or UPVC), the**
glazing** (glass thickness), the **mesh** provision, the **fixing**, the **wall-
frame sealing** (silicone perimeter seal, weep holes, over-flashing), and the **
finishing** (plaster and paint touch-up around the new frame). A rate that quotes
only the frame and glass, leaving sealing and touch-up as extras, isn’t comparable—
and the sealing is the part that keeps the wall dry. The full scope is on our sliding
window and grill work in Thane page.

## Grills — MS vs SS, and the cost-over-time view

Painted **MS grills** are cheapest upfront but need repainting every few years; **
powder-coated MS** lasts longer; **SS 304** costs the most upfront but never rusts
or needs repainting — the right choice on monsoon-facing (west/south-west) elevations,
where the recurring repaint cost of MS adds up. The material-life trade-off is covered
in our [monsoon-proof materials guide](https://jyaniinterior.com/best-materials-thane-homes-monsoon-proof/).

## The sealing detail that prevents leaks

A new window on a poorly sealed wall edge leaks within a monsoon, regardless of 
the frame brand. The detail that matters: a silicone perimeter seal, working weep
holes at the base of the frame, and an over-flashing strip above directing water
away from the joint. This is a civil detail as much as a window one — the wall-edge
correction sits with our [civil contractor rates in Thane](https://jyaniinterior.com/civil-contractor-rates-thane/),
and the waterproofing logic is in our [pre-monsoon waterproofing guide](https://jyaniinterior.com/home-waterproofing-thane-monsoon/).

## Frequently Asked Questions

**How much do sliding windows cost in Thane?** It depends on the frame type (aluminium
2- or 3-track, UPVC), the glazing, the size and the finishing. A complete rate includes
frame, glass, mesh, fixing, wall-frame sealing and touch-up — the exact figure comes
from a quote after a site visit.

**What should a window rate include besides the frame?** Glazing, mesh provision,
fixing, wall-frame sealing (silicone seal, weep holes, over-flashing), and plaster/
paint touch-up around the new frame. A frame-only rate isn’t comparable to a complete
one.

**MS or SS 304 grills — which is better value?** Painted MS is cheapest upfront 
but needs repainting every few years; SS 304 costs more upfront but never rusts 
or needs repainting — better value over time on monsoon-facing elevations.

**Why do new windows sometimes leak?** Usually a poorly sealed wall-frame joint,
not the frame itself. A silicone perimeter seal, working weep holes and an over-
flashing strip are what keep the wall dry.

**Is UPVC worth the extra cost over aluminium?** UPVC offers better sealing and 
insulation and suits noise- or weather-exposed windows, at a premium over aluminium.
Aluminium remains the economical, durable default for most flats.
