DIY Window Installation Troubleshooting in Asheville, NC

Published on

Your satisfaction with your Pella windows and doors is our top priority. If you have a problem with your Pella product that you believe could be related to the window’s installation, taking the following steps could 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 may produce an inaccurate reading. The bubble of your level should rest in the center, signifying 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 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. After that, 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.

After checking plumb, you can check for bowing by measuring the unit horizontally across the top, middle and bottom. The three measurements should all be equal, plus or minus 1/8 inch. It’s important to always measure to and from the same 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 may also inspect the reveal, where the sash meets the frame. The gap should appear the same 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.

Taking the time to do a little troubleshooting on your own can provide helpful information to fix a problem. If it is clear you have run in to one, or even a couple, of these issues, come by the Pella Window and Door Showroom in Asheville or give us a call at 828-202-8673.
