About Autostem

A Local Window Company That Stands Behind Its Work

Autostem installs replacement windows for homeowners across Syracuse, New York and the surrounding Onondaga County communities. We work with vinyl, fiberglass, wood, and composite frames, and we handle everything from a single fogged unit to a full-home project, always with a written installation guarantee and the full manufacturer warranty behind it.

Syracuse weather is hard on windows. The freeze and thaw cycle that grips the streets off Erie Boulevard every winter finds any weak seal, which is exactly why the quality of the installation matters as much as the window itself. We flash carefully, insulate the gaps, and finish every opening so it holds up season after season.

What Sets Us Apart

• Everything in writing. Our installation guarantee and the manufacturer warranty are both spelled out on your estimate, so nothing about coverage is left to memory.
• One crew, start to finish. The same team that measures your home installs it and honors the warranty, so there is never any finger pointing.
• Honest guidance. We explain the NFRC label, the U-factor, and the real difference between vinyl, wood, and fiberglass before you spend a dollar.
• Local and licensed. We are a licensed, insured Syracuse-area company, and a real person answers when you call.
