Basement Window Cost by Type and Configuration
Different basement window styles serve specific purposes and come with varying price points. Your choice should balance functionality, building code requirements, and budget considerations.
Basic Hopper Windows
Cost: $200–$750 installed
Hopper windows are the most economical option for basement installations. They tilt inward from the top, making them ideal for below-grade applications where exterior space is limited. These windows work well in utility rooms, storage areas, and mechanical rooms where egress requirements don’t apply. They provide adequate ventilation and natural light while maintaining security.
Small hopper windows (18″×24″ to 24″×30″) typically cost $200–$440 installed, while medium sizes (30″×36″ to 36″×42″) run $480–$750. These units usually feature vinyl frames with double-pane glass and basic hardware.
Egress Windows for Bedrooms
Cost: $2,500–$4,000+ installed
If you’re creating a basement bedroom, Ontario Building Code requires egress windows for emergency escape. These installations are significantly more expensive because they involve structural modifications. The window opening must provide a minimum clear opening of 0.35 square metres (3.8 square feet) with no dimension less than 380 mm (15 inches).
The higher cost reflects several factors: cutting through concrete foundation walls, installing a window well, adding proper drainage, reinforcing the opening, and ensuring code compliance. Casement windows are popular for egress applications because they provide maximum clear opening when fully opened.
“When homeowners ask about basement bedroom conversions, I always emphasize that egress windows aren’t optional—they’re a life safety requirement. The investment protects your family and ensures your renovation meets legal standards for resale.” — Eugene Siukayev, Project Manager
Sliding Basement Windows
Cost: $340–$810 installed
Sliding windows offer easier operation than hopper styles and work well for wider basement openings. They’re suitable when you need better ventilation or prefer a more traditional window style. Single sliding windows cost $340–$540 installed for medium sizes, while double sliding configurations run $380–$880.
These windows are particularly useful in finished basements where you want more natural light and easier access for cleaning. However, they don’t typically meet egress requirements unless specifically designed and sized for that purpose.
Premium and Custom Basement Windows
Cost: $1,000–$2,500+ installed
Custom basement windows include oversized units, specialty shapes, or aluminum-framed windows for contemporary designs. These installations might feature triple-pane glass for superior insulation, custom colours, or unique configurations to match architectural requirements.
Aluminum windows typically cost 15% to 30% more than vinyl but offer slimmer sightlines and greater strength for larger openings. They’re ideal for modern homes or when you’re installing exceptionally large basement windows.
What Affects Basement Window Installation Costs?
Several variables influence the final price when you install new windows in your basement. Understanding these factors helps you anticipate costs and make informed decisions.
Window Size and Dimensions
Larger windows require more materials and labour. A small 24″×30″ hopper window costs significantly less than a 48″×48″ egress casement. The size directly impacts both the window unit cost and installation time. When planning your project, consider whether you need maximum light or just basic ventilation.
Frame Material Selection
Vinyl windows dominate the Canadian market due to their excellent insulation properties and low maintenance requirements. They perform exceptionally well in our climate and represent the most cost-effective choice. Aluminum frames cost more but suit modern aesthetics and larger spans. Composite materials fall between these options in both price and performance.
Glass Configuration and Energy Efficiency
Double-pane windows with argon gas fill are standard for basement installations. Upgrading to triple-pane glass adds $150–$300 per window but dramatically improves insulation. Low-E coatings enhance energy performance for another $50–$100 per window.
ENERGY STAR™ certified windows meet rigorous performance standards for Canadian climates. These units reduce heat loss, prevent condensation, and lower heating costs. According to Natural Resources Canada, ENERGY STAR certified windows can save homeowners $125–$340 annually on energy bills.
Structural Modifications Required
Installing windows in existing concrete foundations requires cut-out services. This process involves cutting through concrete, installing proper lintels, and reinforcing the opening. Standard cut-outs for small windows add $500–$1,000 to your project. Egress window cut-outs requiring larger openings cost $1,500–$2,500.
If your basement walls need additional waterproofing, drainage improvements, or window well installation, expect another $500–$1,500. These additions ensure long-term performance and prevent water infiltration.
“Many homeowners underestimate the importance of proper drainage around basement windows. We always recommend investing in quality window wells and drainage systems—it prevents costly water damage and protects your investment.” — Vitaly Shapiro, Vice President of Sales
Installation Complexity and Labour
Labour costs vary across Ontario regions. GTA installations typically run $200–$400 per window for straightforward replacements in existing openings. Complex installations requiring structural work, permit coordination, or challenging access cost $500–$1,200 in labour alone.
Professional installation ensures proper sealing, insulation, and code compliance. DIY installations might save money initially but risk air leakage, water infiltration, and code violations that cost more to remedy later.
Building Permits and Code Compliance
Egress window installations always require building permits in Ontario. Permit fees range from $150–$400 depending on your municipality. The permit process ensures your installation meets egress window requirements for safety and emergency access.
Standard window replacements in existing openings typically don’t require permits, but creating new openings or enlarging existing ones does. Factor in inspection fees and potential delays when planning your timeline.
Additional Features and Upgrades
Optional upgrades affect your final cost:
- Multi-point locking systems: Enhanced security features add $50–$150 per window
- Custom colours and finishes: Non-standard colours cost $100–$300 extra per window
- Tempered or laminated glass: Safety glass upgrades add $75–$200 per window
- Interior trim and finishing: Professional trim work costs $100–$300 per window
- Window wells and covers: Galvanized steel wells run $300–$600; covers add $100–$200

How Can You Reduce Basement Window Installation Costs?
Strategic planning and smart choices help you manage expenses without compromising quality or safety. These approaches deliver value while maintaining proper performance standards.
1. Plan Multiple Windows Together
Installing several windows during one project reduces per-window costs. Contractors offer better rates when they can complete multiple installations in a single visit. You’ll save on mobilization fees, permit costs, and labour efficiency. If your basement needs three windows, installing them simultaneously costs less than three separate projects.
2. Choose Standard Sizes and Configurations
Stock window sizes cost significantly less than custom dimensions. Manufacturers produce common sizes in volume, reducing material costs. Standard hopper windows in popular sizes like 24″×30″ or 32″×36″ offer the best value. Custom shapes, colours, or non-standard dimensions add 20%–50% to window costs.
3. Select Appropriate Features for Your Needs
Not every basement window needs premium features. Utility rooms and storage areas function perfectly with basic double-pane vinyl windows. Reserve upgrades like triple-pane glass and custom finishes for living spaces where you’ll notice the benefits. Match window specifications to room function rather than over-specifying everywhere.
4. Time Your Project Strategically
Window companies experience slower periods during late fall and winter. Many offer promotional pricing during these months to maintain steady workflow. Spring and summer represent peak seasons with higher demand and prices. Scheduling your installation during off-peak months can save 10%–15%.
Check available seasonal promotions before finalizing your project timeline. Some manufacturers run special offers that significantly reduce costs on specific product lines.
5. Explore Available Rebates and Incentives
Ontario homeowners may qualify for energy efficiency rebates when installing ENERGY STAR™ certified windows. The Canada Greener Homes Grant provides up to $5,000 for qualifying energy-efficient upgrades. These programs require pre-approval and post-installation verification but offer substantial savings.
Municipal programs sometimes offer additional incentives for basement renovations that add legal dwelling units. Research local programs before starting your project to maximize available benefits.
6. Prepare the Work Area Properly
Clear the installation area before contractors arrive. Remove furniture, stored items, and obstacles that slow work progress. Providing clear access to basement windows reduces labour time and associated costs. Simple preparation saves 1–2 hours of billable labour per window.
7. Maintain Realistic Expectations About DIY
While experienced homeowners can replace windows in existing openings, basement installations involving concrete cutting require professional expertise. Improper installation voids warranties, creates water infiltration risks, and may violate building codes. Professional installation protects your investment and ensures proper performance.
Focus DIY efforts on finishing work like interior trim, painting, or landscaping around window wells. Leave structural modifications and window installation to qualified professionals.

Understanding Egress Window Requirements
Ontario Building Code mandates specific requirements for basement bedroom windows. These regulations ensure occupants can escape safely during emergencies. Understanding these standards helps you plan compliant installations.
Egress windows must meet these minimum specifications:
- Clear opening area: Minimum 0.35 square metres (3.8 square feet) of unobstructed opening
- Minimum dimensions: No dimension less than 380 mm (15 inches) in any direction
- Maximum sill height: Window sill cannot exceed 1,500 mm (59 inches) above the floor
- Operational requirements: Window must open easily without tools or special knowledge
- Window well depth: Wells deeper than 760 mm (30 inches) require permanent ladder or steps
These requirements apply to any basement bedroom, whether in a single-family home or secondary suite. Non-compliance creates serious liability issues and affects your ability to legally rent or sell your property.
When you’re planning to add natural light to your basement while creating a legal bedroom, egress windows become mandatory. The investment ensures safety and maintains property value.
Choosing the Right Window Company
Selecting a qualified installer significantly impacts project success, final costs, and long-term satisfaction. Canadian homeowners should evaluate several factors when choosing a window company.
Look for these credentials and qualifications:
- Proper licensing and insurance: Verify contractor licenses and liability coverage
- Industry certifications: ENERGY STAR™ certification and manufacturer training demonstrate expertise
- Established reputation: Check BBB ratings, Google reviews, and HomeStars feedback
- Comprehensive warranties: Quality companies offer both product and installation warranties
- Local experience: Familiarity with Ontario building codes and climate requirements matters
