Your satisfaction with your Pella windows and doors is our priority. Should you find a problem with your Pella product that you think could be related to the window’s installation, completing the following steps may help determine if the product is installed level, square and plumb.
First, take a level and set 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 could give an inaccurate reading. The bubble of your level should settle in the center, demonstrating the product is installed level.
Next, check plumb of your window or door. Plumb means the window or door is straight down or up, vertically. To check 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.

It’s crucial to always measure to and from a common point on both sides for consistency. Finally, determind if your window or door is square by measuring from corner to corner 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 could 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. Every side of your product should appear the same, signifying the product is installed level, square, and plumb.
