INSERT VS. FULL-FRAME WINDOW INSTALLATION: WHICH IS BETTER?

Proper installation is key to long-term window performance. But apart from proficiency, the very replacement method used matters, too. There are many ways to replace windows, but the most common kinds are insert and full-frame window installation. The former only involves setting new units into the existing frames whereas the latter requires the replacement of the entire window.

We discuss both below.

Which One Makes More Sense?

In Renewal by Andersen® of St. Louis’s book, the use of the insert is the more attractive choice since it’s less disruptive and costly. However, it may not apply to your situation when your old window sill and frame are no longer square, solid  and in good repair.

Sometimes, the existing construction doesn’t lend itself to insert windows installation because it’s excessively leaky. When the damage to the old frame is beyond repair, full-frame replacement is necessary to guarantee structural integrity and prevent air infiltration.

But then again, structurally sound, old frames don’t necessarily qualify for insert window installation. If the size of your existing wall openings doesn’t meet the latest fire egress codes, full-frame replacement is required.

"Our installation team was top notch. While they said they were sending a "team"to install 21 windows it was only two people. But I see why, the process was seamless and everything was done correctly and consistently with the leadership of Clayton. We had a tiny problem with one window within a week of installation and their response time was prompt to remedy the situation. Our windows are beautiful. Our home is warm and cozy."

"Love the windows and patio door. We want to finish the whole house when we can financially. We give Anderson and employees, especially the sales rep Mike that came to our house, the highest rating. Mike was knowledgeable and courteous. Also not high pressure."
