Your satisfaction with your Pella windows and doors is our priority. Should you have a problem with your Pella product that you believe might be related to the window’s installation, taking the following steps could 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 put it on the sashes or panels of the product because it may produce an inaccurate reading. The bubble of your level should settle 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 check 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 both sides. The bubble should fall in the center on both sides, representing that 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 each of the three places should all be equal, plus or minus one eighth of an inch. It’s important to always measure to and from a common point on both sides for consistency. After this, find out 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 have the same look from top to bottom and left to right. All sides of your product should appear the same, indicating the product is installed level, square, and plumb.
