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.

"Very pleased with installation of six windows and a ProVia entry door. I love the look of the windows and door. I am pleased that my wife is thrilled with the look of the door. She is very pleased that the bronze color fits in well with the color of the brick."

"I just had my Renewal by Andersen windows installed and couldn’t be happier, the entire process went very smoothly. The windows are high quality and look great. But the installers Roy, Zack and Jordan were the stars, they introduced themselves upon arrival walked me thru everything they were going to do and when they finished took me to each window to make sure I was completely satisfied. They were clean and courteous and I would definitely recommend and have them work in my home again."

"Wonderful experience with knowledgeable, competent employees. We had Andersen windows in a previous house & didn’t even consider anything else this time. After replacing our patio door almost two years ago, we replaced all our windows this year. What a difference over builder-grade windows, especially in the really cold temperatures we’ve had this year. Andersen windows may be a little more expensive than other brands, but they are top quality."
