Choosing Basement Storm Windows

Start with where your storm window will mount and how your existing window opens. Explore interior storm windows for an inside-mounted layer, exterior storm windows for fixed or ventilating openings, or specialty storm windows for distinctive shapes. Check the mounting requirements and use our measuring guides before ordering.

What affects the price?

Dimensions determine the size of your frame and glass. Glass options, frame finish, and configuration—including fixed or operating panels, track count, and specialty shapes—also affect the price. Configure your chosen product for available pricing, or request a quote for details that need review.

FAQs

Which storm window style is best for a basement window?

Match the storm window to the shape and operation of the existing opening. Fixed picture models work for non-opening glass, horizontal sliders suit short and wide openings, and vertical models fit taller sash that move up and down.

Can I order an operating basement storm window with a screen?

Yes. The horizontal and vertical two-track and triple-track models shown here include screen configurations for ventilation. Choose the track style that matches how you want the glass and screen panels to move.

How should I measure a basement opening near a window well?

Measure the exterior mounting opening at multiple points and use the smallest usable width and height. Also confirm the available depth, sill condition, well clearance, fastener access, and any obstruction that could interfere with installation or panel movement.

Will a basement storm window solve a moisture problem?

A storm window can reduce direct weather exposure, but it does not correct poor grading, blocked drains, leaks, or an active water-intrusion problem. Keep the sill and weep paths clear, and address drainage concerns before covering the opening.

Are basement storm windows made to standard sizes?

Each window is fabricated from the measurements entered with the order. This made-to-measure approach is useful for older basement openings, which often vary in width, height, trim condition, and squareness.
