Andersen Renewel Window air leaks

I came across an old thread on the forum where someone was describing a similar problem with these windows. I have Anderson renewal replacement windows. At the bottom corners of each window there is air penetration. It is only at the corners and of course is only noticeable in the very cold weather. We have had extreme Arctic conditions in the Northeast at night and you can almost feel it blowing in it is so cold. Previously the contractor came and installed thicker seals believing this would address the issue but it has not. Any suggestions on why this is happening or potential solution was to mark

Josh,

Measure the width of the window at the top, middle and bottom. They all three should be exactly the same. I would also use a framing square to check the window. This sounds like someone did not square the window into the rough opening.

Maybe this is a dumb question but where should I measure with the square? The attachment will show the issue at hand.

Josh,

A framing square is not the tool one would use to measure. A Tape measure is the tool for taking a measurement. A Framing square will tell you if the 90 degree corners are in fact a true 90 degrees. If they are not, the window will not operate properly. Verify that each corner of the case is square. And then measure across the top, the middle and the bottom of the case to see if the opening is the same width. If it is not, you will need to take the casing off and apply/remove shims where needed. If the case is not square, it will need to be squared by adding, or removing shims where needed.

I have never liked replacement windows because of the vertical gap the entire lingth of the window. The older windows have only a small horizontal gap that is closed tight when the window locks. And there are no vertical gaps in the casement.

Andy I measured as you suggested and all measurements were consistent. What part of the window should I measure with the square? Starting point? Inside or out? Any help is appreciated.

Josh,

Again, a framing square is not a tool for measuring. It is a tool for checking for square. You want to ensure that the window is square. That each corner is at a 90 degree angle.
