Your satisfaction with your Pella windows and doors is our highest priority. Should you have a problem with your Pella product that you think could be related to the window’s installation, taking 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 set it on the sashes or panels of the product as it may not give an accurate reading. The bubble of your level should fall in the center, indicating the product is installed level.
Next, test plumb of your window or door. Plumb means the window or door is straight down or up, vertically. To examine for plumb, put your level on the two vertical side jambs on the exterior face to ensure the product is plumb from the inside out. Next, you’ll check for plumb from left to right by placing the level on each of the two sides. The bubble should fall in the center on both sides, indicating the product is installed plumb.

Lastly, find out if your window or door is square by measuring from each 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 examine the reveal, where the sash meets the frame. The gap should have the same look from top to bottom and left to right. Each side of your product should appear the same, signifying the product is installed level, square, and plumb.
