Your satisfaction with your Pella windows and doors is our highest priority. Should you have a problem with your Pella product that you suspect 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 set 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 not give an accurate reading. The bubble of your level should fall 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 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. Next, you’ll check for plumb from left to right by placing the level on each side. The bubble should fall in the midpoint on both sides, signifying the product is installed plumb.
After checking plumb, you can examine 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 a common point on both sides for consistency. Finally, find out 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 for the product to be
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. Each side of your product should appear the same, demonstrating the product is installed level, square, and plumb.
