Replacing your basement windows may not be the most exciting home improvement project, but it’s one of the most important. Installing new basement windows can help with drafts, leaks, and old frames. They improve energy efficiency, let in more natural light, and can raise your home’s resale value.
But the big question is — how much does it cost to replace basement windows in 2025?
Let’s break down everything you need to know: the average cost, price factors, window types, and whether DIY is a smart move or a risky gamble.
Average Basement Window Replacement Cost in 2025
Basement window replacement costs typically range from $300 to $1,200 per window. This depends on the type of window, its size, and local labour rates.
Here’s a quick breakdown:
| Item | Cost Range (Per Window) |
|---|---|
| Basic Vinyl Hopper | $100 – $300 |
| Mid-range Slider | $250 – $500 |
| High-End Egress | $600 – $1,200+ |
| Labor (Standard) | $200 – $400 |
| Labor (Complex Job) | $400 – $800 |
Pro Tip: Always get at least 2–3 quotes from local professionals to avoid overpaying.
What Affects the Cost of Replacing Basement Windows?
Several key factors impact the total cost of your basement window replacement:
1. Window Type
Different window styles come with different price tags:
-
Hopper Windows: Affordable and common in basements; open inward.
-
Slider Windows: Easy to use and allow more light.
-
Casement Windows: Hinged on the side; more expensive.
-
Egress Windows: Required in finished basements for safety; costly due to size and installation.
2. Size and Material
Larger windows or those made of premium materials (like fiberglass or wood) cost more than standard vinyl.
3. Glass Options
Double-pane or Low-E glass improves insulation but adds to the price. Triple-pane or gas-filled options are even more energy-efficient (and expensive).
4. Wall Structure
If your basement walls are concrete or brick, the labor becomes more intensive, increasing your overall cost.
5. Permit and Code Requirements
When installing egress windows, you might need permits, inspections, or structural changes. These can increase your project cost by $500 to $2,500.
DIY vs. Professional Installation: Which Is Better?
You can install basement windows yourself if you’re handy, but there are some things to consider:
✅ DIY Pros:
-
Save on labor (typically $200–$500 per window)
-
Control over the project
❌ DIY Cons:
-
Risk of leaks or poor insulation
-
Requires tools, materials, and experience
-
Time-consuming and physically demanding
If your project involves concrete cutting, structural changes, or egress window installation — it’s best to hire a licensed professional.
