Your satisfaction with your Pella windows and doors is our 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 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 place it on the sashes or panels of the product as it could give 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 test 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 both sides. The bubble should fall in the midpoint on both sides, signifying the product is installed plumb.
Third, you can look for bowing by measuring the unit horizontally across the top, middle and bottom. The three measurements should all be equal, plus or minus 1/8 inch. It’s important to always measure to and from a single 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, indicating the product is
You could also examine the reveal, where the sash meets the frame. The gap should appear the same 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.
