Your satisfaction with your Pella windows and doors is our top priority. If you have a problem with your Pella product that you think may be related to the window’s installation, taking 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 put it on the sashes or panels of the product as it may produce an inaccurate reading. The bubble of your level should fall in the center, demonstrating 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, 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 each of the two sides. The bubble should fall in the midpoint on both sides, signifying the product is installed plumb.
Third, 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 one eighth of an inch. It’s crucial to always measure to and from the same point on both sides for consistency. After this, 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 to indicate the product is
You can also examine 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, signifying the product is installed level, square, and plumb.
