Your satisfaction with your Pella windows and doors is our top priority. Should you find a problem with your Pella product that you think could be related to the window’s installation, taking the following steps could help determine if the product is installed level, square and plumb.
First, take a level and place 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 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 check 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. After that, you’ll check for plumb from left to right by placing the level on each side. The bubble should fall in the middle on both sides, signifying the product is installed plumb.
After checking plumb, you can look 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 a common point on both sides for consistency. Finally, determind 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 can also inspect the reveal, where the sash meets the frame. The gap should appear 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.
