Your satisfaction with your Pella windows and doors is our highest priority. Should you find a problem with your Pella product that you think could be related to the window’s installation, completing the following steps can 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 because it may produce an inaccurate reading. The bubble of your level should settle 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 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. Next, 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, indicating the product is installed plumb.
After checking plumb, you can examine for bowing by measuring the unit horizontally across the top, middle and bottom. The three measurements should all be equal, plus or minus one eighth of an inch. It’s critical 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 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 examine 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, demonstrating the product is installed level, square, and plumb.
