Your satisfaction with your Pella windows and doors is our top priority. Should you have a problem with your Pella product that you think may be related to the window’s installation, completing the following steps may help determine if the product is installed level, square and plumb.
First, get 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 as it may produce an inaccurate reading. The bubble of your level should fall in the center, indicating the product is installed level.
Next, test 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, indicating 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 these three places should all be equal, allowing 1/8 inch of leeway. It’s critical to always measure to and from a single point on both sides for consistency. After this, 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, indicating the product is
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. Every side of your product should appear the same, indicating the product is installed level, square, and plumb.
