What do they cost?

window attachments cost

Indow windows start at $24 a sq. ft.

That’s only $268 for a for a 3′ x 4′ window opening.


Consider the cost and disruption of replacing your windows. A vinyl window averages $66-$87/sf. A wood window averages $71-$109/sf. With Indow inserts averaging between $24-$36/sf MSRP, your window project can cost a fraction of other options.

If you live in dealer territory, a dealer will laser measure your windows and also install the inserts. They will cover all costs in your estimate, which normally includes a measure and installation fee as well as your local sales tax.
