Understanding Insert and Full-Frame Window Installation

At Renewal by Andersen® of Austin, we regularly replace windows in homes that range from nine to 109 years old. Each project is unique and requires a certain kind of installation. While many methods are available, the two most common forms of window replacement are the insert and the full-frame installation methods.

When Insert Window Installation Makes Sense

The insert installation method involves setting the windows into existing frames, which makes the project less costly and disruptive. Leaving the old sill and frame untouched is logical when these components are in good shape.

In this kind of window replacement, the casing and the trim need to stay in place throughout the process. Because of that, we’ll first verify that the existing construction is structurally sound enough to allow the use of the insert.

When Full-Frame Window Installation Makes Sense

The full-frame replacement method involves the removal of the entire existing window before the new unit can be installed. This method is necessary when the old frame has deteriorated beyond repair. Full-frame window installation lets you maximize the energy efficiency of your replacement double-hung, bay, bow, picture and custom windows. In some cases, we may need to replace the existing frame even if it’s still in good shape in order to comply with the latest fire egress code.

With Renewal by Andersen of Austin, you can rest assured we’ll choose the correct installation method for each of your replacement casement and sliding windows. Our project technician, your personal construction expert, will assess the condition of your frames, sash, casing and trim to determine the best method to use. Our Certified Master Installers are adept at wall material and thickness variations, as well as different types of casing and sill construction, ensuring flawless work.
