How Long Does a Window Installation Take? The Quick Answer

Are you looking for a quick answer to how long it takes to install windows? Southwest Exteriors delivers with an expert best estimate answer that takes less than a minute. Of course their are factors that can add time to a project and those are quickly addressed as well.

How Long Does Window Installation Take?

That’s a great question—and the honest answer is: it depends on a few variables.

Assuming we’re not working with stucco, a typical installation crew can complete about 8 to 10 windows per day. That’s a reliable benchmark we aim to hit on most standard projects.

However, several factors can affect that timeline:

Trim work & painting – If we’re replacing trim or doing finish work, that will add time

Home height – Multi-story homes may require scaffolding, which slows things down

Window condition – Older or damaged frames can require extra prep work

Our goal isn’t just speed—it’s quality and care. We focus on being as gentle on the home as possible, paying attention to every detail, and making sure the job is done right the first time.
