Your satisfaction with your Pella windows and doors is our priority. Should you find a problem with your Pella product that you believe might be related to the window’s installation, trying the following steps could help determine if the product is installed level, square and plumb.
First, get a level and put it on the frame of the product, across the bottom or sill. Do not put it on the sashes or panels of the product since it may not give an accurate reading. The bubble of your level should settle in the center, signifying the product is installed level.
Next, examine plumb of your window or door. Plumb means the window or door is straight down or up, vertically. To examine for plumb, set your level on the two vertical side jambs on the exterior face to ensure the product is plumb from the inside out.

The measurements of these three places should all be equal, plus or minus one eighth of an inch. It’s crucial to always measure to and from a common point on both sides for consistency. Lastly, see if your window or door is square by measuring from one corner to the other in an X fashion on the outside of the product. The measurements should be within 1/8 inch of each other, indicating the product is
You may also inspect the reveal, where the sash meets the frame. The gap should look the same from top to bottom and left to right. Each side of your product should appear the same, indicating the product is installed level, square, and plumb.
