This calculator gives an estimate for planning by adding up the main cost parts: glass materials, labor, supplies, and (optionally) removal & disposal.
Materials
Material cost = (Number of windows) × (Avg glass area in ft²) × (Glass rate in $/ft²)
Labor
Labor cost = (Number of windows) × (Base labor per window) × (Complexity factor) × (Location factor)
Total
Total = (Materials + Labor + Supplies + Disposal) × (1 + Contingency)
Notice: This uses average costs and factors to ensure it is as accurate as possible, but it is still best for approximate cost estimation for planning, and should not replace a contractor. Actual window glass replacement costs can depend on local market costs, contractor labor rates, glass thickness/coatings (e.g., Low-E), IGU configuration, site access, frame condition, and disposal requirements.
Are you wondering how much it will cost to replace your window glass? Don't panic! In this post, we will guide you step-by-step on using our Window Glass Replacement Cost Estimator to calculate window glass replacement cost instantly.
We did our best to make this calculator as accurate as possible using average costs, and it also allows you to enter custom costs. However, use this estimate for planning purposes only and do not treat it as an exact glass replacement cost, as it varies depending on many factors.
In this guide we explain:
Now let's dive in and understand the window glass replacement cost calculator in depth.
On average, window glass replacement costs homeowners around $380 per window, but prices can range from $300 to $900 depending on location, market conditions, and specifications.
Many factors affect the cost, such as glass type, window size and shape, window type, labor, location, and frame condition. That’s why contacting local contractors for pricing confirmation is essential. Generally, we show you an average list that can give you a cost idea.
| Glass Type | Average Cost Range (per window) |
|---|---|
| Single-Pane Glass | $100 – $400 |
| Double-Pane Glass | $300 – $900 |
| Triple-Pane Glass | $400 – $1,000 |
| Tempered Glass | $200 – $700 |
| Laminated Glass | $275 – $750 |
| Low-E Glass | $350 – $850 |
| Argon / Krypton Gas-Filled Glass | $375 – $1,200 (additional) |
Glass cost can vary based on location and market conditions, but we have prepared an average glass cost and cost range table below (source: thisoldhouse.com):
| Type of Glass | Cost Range (per window) | Average Cost (Per window) |
|---|---|---|
| Argon-filled glass | $375–$850 | $613 |
| Frosted glass | $350–$800 | $575 |
| Krypton-filled glass | $525–$1,190 | $858 |
| Laminated glass | $275–$625 | $450 |
| Low-e glass | $350–$840 | $595 |
| Stained glass | $100–$10,000 | $5,050 |
| Tempered glass | $180–$700 | $440 |
A Window Glass Replacement Cost Estimator is a handy yet powerful tool that helps homeowners and contractors estimate the cost of replacing window glass in one or more windows.
The calculator accounts for many factors, such as the number of windows, glass type, average glass area in square feet (ft²), installation complexity, location and whether you need to remove and dispose the old glass — all of which are used to accurately estimate the window glass replacement costs.
The calculator uses a series of simple formulas to estimate the window glass replacement cost. You can take a look at the “How it works” section to see the exact formulas and explanations.
We will also explain a real-world example to help you understand how the cost is calculated:
For example, let’s assume that in your house, 5 windows need glass replacement. You decide to choose a double-pane IGU glass type and measure an average glass area of 9 ft². You also decide to include disposal of the old glass or IGU.
You can contact a local contractor or your local market to determine the current costs:
We have all the data needed. Now, let’s combine them to make the interpretation easier. We are assuming the following costs in this example:
Now, perform the calculation to approximate the total cost and cost per window:
So, we have calculated the glass replacement cost for 5 windows at a total of $2,564.50, with a per-window cost of $512.90.
Our calculator uses a series of formulas, conditions, and logic to give you an accurate estimate in an easy-to-read and understandable format. Use our calculator to instantly estimate your costs.
