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 because it may produce an inaccurate reading. The bubble of your level should fall in the center, indicating the product is installed level.
Next, check plumb of your window or door. Plumb means the window or door is straight down or up, vertically. To test for plumb, place 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 of the two sides. The bubble should fall in the middle on both sides, representing that 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, plus or minus 1/8 inch. It’s crucial to always measure to and from a single point on both sides for consistency. Lastly, see 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 inspect the reveal, where the sash meets the frame. The gap should look the same from top to bottom and left to right. All sides of your product should appear the same, demonstrating the product is installed level, square, and plumb.
