Your satisfaction with your Pella windows and doors is our highest priority. Should you find a problem with your Pella product that you suspect may 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 put it on the frame of the product, across the bottom or sill. Do not set it on the sashes or panels of the product because it may produce an inaccurate reading. The bubble of your level should rest 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 examine 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. After that, 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, signifying 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 important to always measure to and from the same point on both sides for consistency. Finally, see 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 to indicate the product is
You can 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, indicating the product is installed level, square, and plumb.
