Your satisfaction with your Pella windows and doors is our top priority. If you have a problem with your Pella product that you believe might be related to the window’s installation, trying the following steps may help determine if the product is installed level, square and plumb.
First, take 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 settle 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 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 both sides. The bubble should fall in the midpoint on both sides, signifying 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 each of the 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. Finally, 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, indicating the product is
You can 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, indicating the product is installed level, square, and plumb.
