DIY Window Installation Troubleshooting in Ketchum, ID

Published on

Your satisfaction with your Pella windows and doors is our priority. If you have a problem with your Pella product that you think may be related to the window’s installation, taking the following steps can help determine if the product is installed level, square and plumb.

First, grab a level and place it on the frame of the product, across the bottom or sill. Do not set it on the sashes or panels of the product since it could give 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 check 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. After that, 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 center on both sides, signifying the product is installed plumb.

When you finish checking plumb, 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, plus or minus one eighth of an inch. It’s critical to always measure to and from a common point on both sides for consistency. Lastly, find out 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 for the product to be installed square.

You can also check 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, demonstrating the product is installed level, square, and plumb.
