Your satisfaction with your Pella windows and doors is our top priority. If you have a problem with your Pella product that you think 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, grab a level and place it on the frame of the product, across the bottom or sill. Do not put it on the sashes or panels of the product because it may not give an accurate reading. The bubble of your level should fall in the center, demonstrating 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, place 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 both sides. The bubble should fall in the midpoint on both sides, indicating the product is installed plumb.
When you finish checking plumb, you can check for bowing by measuring the unit horizontally across the top, middle and bottom. The measurements of these three places should all be equal, plus or minus 1/8 inch. It’s critical to always measure to and from the same point on both sides for consistency. Lastly, find out 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 can also check the reveal, where the sash meets the frame. The gap should look the same from top to bottom and left to right. All sides of your product should appear the same, indicating the product is installed level, square, and plumb.
