DIY Window Installation Troubleshooting in Washington DC, DC

Published on

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

First, get 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 since it may not give an accurate reading. The bubble of your level should rest in the center, demonstrating 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 each side. The bubble should fall in the middle on both sides, indicating the product is installed plumb.

When you finish checking plumb, you can look for bowing by measuring the unit horizontally across the top, middle and bottom. The three measurements should all be equal, plus or minus one eighth of an inch. It’s critical to always measure to and from a single point on both sides for consistency. Lastly, 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, indicating the product is installed square.

You may also examine 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 offer helpful information to solve a problem. If it is clear you have found one, or even a couple, of these issues, come by the Pella Window and Door Showroom in Washington DC or give us a call at 301-957-7000.
