Understanding the Window Installation Timeline

Replacing your home’s windows is a smart investment for energy efficiency, comfort, and curb appeal. But one question many Chicago homeowners ask is, “How long will the installation take?” The answer depends on the size of your project, the type of windows, and the condition of your existing frames.

Average Time for Single Window Installation

For a standard-sized replacement window in good condition frames, installation can take about 1–2 hours. This includes removal of the old window, prepping the opening, installing the new unit, sealing it properly, and performing a quick quality check.

Full-Home Window Replacement

If you’re replacing all your windows, the timeline typically spans 1–3 days for an average home. Larger homes, complex window designs, or custom sizes may take longer.

Factors That Affect Installation Speed

Weather conditions – Chicago’s winters and rainy days can slow down the process.

Window type – Bay and bow windows require more time than standard double-hung units.

Structural repairs – If there’s rot or frame damage, extra work will be needed.

Preparing Your Home for Faster Installation

Clear furniture and décor near windows.

Ensure installers have easy access both inside and outside.

Confirm parking space for the installation crew’s truck or trailer.
