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.

"I'm getting ready to do my 2nd round of window installation with Anderson Windows. I really appreciate the great financing options that they offer! They have top notch sales and installation experts who are very kind and considerate of their customers' wishes. The windows I have installed look great and I am so excited to get the next group of windows put in. My house looks so much brighter with my new windows. I definitely recommend Renewal by Andersen of St. Louis."

"We recently contracted with Renewal by Andersen to replace 5 windows in our home. First of all, we were very delighted that the time from contract to installation was less than two months. Joel and Craig arrived precisely at the agreed-upon time and spent less than four hours from start to completion of installation, including time to demonstrate opening/closing the windows and any questions we had. We were very pleased with the knowledge and professionalism of Joel and Craig, and, of course, we’re very pleased with the windows and how nice they look. We definitely recommend Renewal by Andersen."

"I replaced my front door and several windows. The install team did a great job with installation and clean up. Even covered floors and stairs. The team was very courteous and did a very professional job. Now our windows look great and we love our new door. I would recommend Renewal by Anderson in a heartbeat."
