Your satisfaction with your Pella windows and doors is our highest priority. Should you find a problem with your Pella product that you believe might be related to the window’s installation, trying the following steps can help determine if the product is installed level, square and plumb.
First, grab a level and put 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 rest in the center, signifying 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 test 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. After that, you’ll check for plumb from left to right by placing the level on each side. The bubble should fall in the center on both sides, indicating the product is installed plumb.
After 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, allowing 1/8 inch of leeway. It’s critical to always measure to and from the same 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 for the product to be
You could also check the reveal, where the sash meets the frame. The gap should appear the same from top to bottom and left to right. All sides of your product should appear the same, signifying the product is installed level, square, and plumb.
