Your satisfaction with your Pella windows and doors is our top priority. If you have 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, take a level and place 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 not give an accurate reading. The bubble of your level should fall in the center, indicating 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 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. After that, you’ll check for plumb from left to right by placing the level on both sides. The bubble should fall in the middle on both sides, signifying the product is installed plumb.
Third, 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, allowing 1/8 inch of leeway. It’s important to always measure to and from a single point on both sides for consistency. After this, see 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 to indicate the product is
You can also inspect the reveal, where the sash meets the frame. The gap should appear the same from top to bottom and left to right. Each side of your product should appear the same, demonstrating the product is installed level, square, and plumb.
