Your satisfaction with your Pella windows and doors is our highest 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 can 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 put it on the sashes or panels of the product since it may not give an accurate reading. The bubble of your level should rest 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 examine 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. Then, you’ll check for plumb from left to right by placing the level on each side. The bubble should fall in the midpoint on both sides, signifying the product is installed plumb.
When you finish 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 important to always measure to and from a single point on both sides for consistency. Finally, see if your window or door is square by measuring from one 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 may also inspect the reveal, where the sash meets the frame. The gap should have the same look from top to bottom and left to right. Every side of your product should appear the same, signifying the product is installed level, square, and plumb.
