DIY Window Installation Troubleshooting in Kalamazoo, MI

Published on

Your satisfaction with your Pella windows and doors is our highest priority. If you have a problem with your Pella product that you think could be related to the window’s installation, trying the following steps could 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 set it on the sashes or panels of the product as it may not give an accurate 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 each side. The bubble should fall in the midpoint on both sides, indicating the product is installed plumb.

Third, 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, allowing 1/8 inch of leeway. It’s important to always measure to and from a common point on both sides for consistency. Lastly, 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 to indicate the product is installed square.

You may 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.
