DIY Window Installation Troubleshooting in Hanover, MA

Published on

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

First, grab a level and put 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, 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 both sides. The bubble should fall in the center on both sides, indicating the product is installed plumb.

Third, you can check 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 crucial to always measure to and from a common point on both sides for consistency. After this, 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 could also check the reveal, where the sash meets the frame. The gap should look the same from top to bottom and left to right. All sides of your product should appear the same, indicating the product is installed level, square, and plumb.

Doing a little troubleshooting on your own can offer helpful information to fix a problem. If it is clear you have run in to one, or even a couple, of these issues, visit the Pella Window and Door Showroom in Hanover or give us a call at 781-826-8005.
