Your satisfaction with your Pella windows and doors is our top priority. If you have a problem with your Pella product that you believe could be related to the window’s installation, taking the following steps can 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 place it on the sashes or panels of the product since it may produce an inaccurate reading. The bubble of your level should fall 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 check 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. Then, you’ll check for plumb from left to right by placing the level on both sides. The bubble should fall in the center on both sides, representing that the product is installed plumb.
When you finish checking plumb, you can look for bowing by measuring the unit horizontally across the top, middle and bottom. The three measurements should all be equal, allowing 1/8 inch of leeway. It’s important to always measure to and from a single point on both sides for consistency. Finally, 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 may 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, demonstrating the product is installed level, square, and plumb.
