Windows – Hopper Windows
Hopper windows are compact, inward-opening windows commonly used in basements, bathrooms, and utility areas. Their design helps improve airflow and moisture control while maintaining strong insulation and security, making them ideal for small or below-grade spaces.
Hopper windows are an excellent solution for areas where ventilation, moisture control, and security are priorities. At Milton Windows and Doors Services Inc., we provide professional hopper window installation, replacement, and repair for residential and light commercial spaces.
Engineered for compact and below-grade environments, hopper windows allow efficient airflow while maintaining reliable insulation and durability. Their inward-tilting sash design makes them ideal for basements, laundry areas, utility rooms, and other tight spaces with limited exterior clearance. When properly installed, hopper windows help reduce humidity, improve indoor air quality, and maintain year-round comfort.
A hopper window is a compact, bottom-hinged window that opens inward from the top. When opened, the sash tilts into the room, allowing fresh air to circulate downward while keeping water and debris outside.
This inward opening mechanism provides:
Secure ventilation
Strong weather protection
Tight sealing when closed
Space-efficient operation
Because hopper windows do not open outward, they are especially suitable for below-grade applications where obstacles such as soil, walkways, or exterior structures make other window styles impractical. Many homeowners choose hopper windows for their balance of practicality, performance, and improved security.



Hopper windows are highly efficient at releasing trapped moisture and stale air. This makes them a preferred option for basements, bathrooms, laundry rooms, and utility areas where humidity levels can rise quickly.
Their small footprint and inward-opening action allow installation in narrow wall openings without obstructing outdoor access, pathways, or landscaping.
When closed, hopper windows form a tight compression seal that reduces heat loss and drafts. Modern options include insulated multi-pane glazing, Low-E coatings, and thermal-resistant frames for better energy savings throughout the year.
The inward-opening configuration makes it difficult to force open from the exterior. Combined with secure locking systems, this design delivers added protection—especially valuable for basement installations.
The tilt-in sash allows convenient cleaning from inside the home without needing ladders or exterior access. Vinyl and composite frames resist moisture, corrosion, and temperature changes with minimal maintenance required.
Built to handle rain, wind, and fluctuating temperatures, hopper windows help reduce water intrusion, moisture build-up, and air leakage.
