DIY Window Installation Troubleshooting in Charlotte, North Carolina

Published on

Your satisfaction with your Pella windows and doors is our priority. Should you find a problem with your Pella product that you believe could be related to the window’s installation, taking the following steps can 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 place it on the sashes or panels of the product because it could give an inaccurate reading. The bubble of your level should rest in the center, signifying 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 check 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. After that, you’ll check for plumb from left to right by placing the level on both sides. The bubble should fall in the middle on both sides, signifying 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 each of the 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. Finally, find out 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 for the product to be installed square.

You could 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. Each side of your product should appear the same, indicating the product is installed level, square, and plumb.

Taking the time to do a little troubleshooting on your own can offer helpful information to resolve a problem. If you find that you have stumbled upon one, or even a couple, of these issues, stop by the Pella Window and Door Showroom in Charlotte or give us a call at 704-228-9149.
