How to Install Storm Windows

We offer installation coordination through our installer network, and we do our best to connect you with a qualified local installer. Availability in your area is not guaranteed. You can also install the windows yourself using our installation guides, or hire a local handyman or contractor. We are growing the network and welcome professionals who would like to join.

Do-it-yourself storm window installation can be practical for an accessible opening if you have the tools and can follow the product instructions. Dry-fit first, keep the frame square, fasten as specified, and test operation. Use an installer for difficult access, heavy panels, or damaged surrounds.

Some interior systems are suitable for homeowner installation. Check the required mounting depth, hardware clearance, and attachment method for the specific model. Compression-fit and surface-mounted systems do not use the same installation process.

A homemade storm window generally involves a square frame, a suitable glass or acrylic panel, a compatible glazing method, perimeter seals, and secure mounting. The details depend on the opening and material. This guide covers installing manufactured units; it is not a fabrication plan for homemade glass assemblies.

Choose the mounting system first, then measure at the position where that system will sit. Record each reading requested by the measuring guide and distinguish opening size from finished frame size. Do not apply an allowance unless the product instructions specify it.
