Window installation methods

We offer two window replacement methods: full-frame and insert. As part of your consultation, our local Infinity partner will assess your windows’ condition to identify the best option for your home. One-size does not fit all when it comes to window replacement installation. No matter which option is recommended, you’ll enjoy maximum efficiency.

Full-frame window replacement

If you have concerns about water or structural damage, full-frame replacement is the appropriate installation method. During a full-frame installation project, the entire window and trim is removed and replaced. Full-frame replacement is also used for new window styles or enlarging your existing opening for a bigger view.

Insert window replacement

Insert replacement is an efficient approach if your existing window frames are in good condition and you only need to replace your sash and hardware. Our insert solution installs directly into your existing window frame with no disruption to existing trim, interior walls or exterior siding.


Window replacement evaluation

Any window replacement installation will start with an initial in-home consultation to review your project’s particular needs and requirements. A local Infinity expert will ask you how many windows and doors need to be replaced and walk you through the basics of window replacement.
